Insights

Reflect, adapt, and grow As the calendar turns toward the final weeks of 2025, it’s a perfect moment to reflect on what has stood out this year at Design World, and to preview the direction we’ll be heading as we enter 2026. It’s been a busy, vibrant year for design engineering content, and the pace of change is only accelerating.

What stands out most in hindsight is an age-old theme: successful engineering teams do not work in silos.

The designs of tomorrow — complex mechanical systems embedded with smart sensors, actuated with precision, connected to real-time data flows, and optimized for energy efficiency — increasingly require integrated thinking.

Our content has mirrored that shift, providing the component fundamentals you expect and important context within systems and applications.

For engineers and product designers, all of this prompts change. Not a makeover or complete overhaul, but strategic adaptation and evolution. The common theme is that the boundaries between disciplines are blurring and require more knowledge overlap, whether you’re designing a linear motion system for a packaging machine, choosing the right connectivity devices for an industrial robot, or integrating AI-driven analytics into a mechanical product.

Though designers and engineers must continuously refine their expertise in their domains, they also need to expand their understanding to ensure applicability, integration with emerging applications, and adaptability to future needs.

At Design World, our editors are committed to helping design engineers,

Ultra-thin chiplet materials put silicon to shame As artificial intelligence (AI), robotics, quantum computing, and edge workloads grow in complexity, traditional silicon-based architectures may be hitting physical and architectural limits. Rising energy costs, slower data transfer, and fragmented chiplet packaging are constraining progress across industries. CDimension aims to solve these challenges, starting with new materials and progressing toward a monolithic 3D architecture based on atomically thin chiplets.

“The world’s demand for computational power is accelerating faster than traditional hardware can evolve,” said Jiadi Zhu, founder and CEO of CDimension, and an MIT Ph.D. in electrical engineering with deep expertise in 2D materials and monolithic 3D integration. “We’re no longer limited by chip architecture alone — we’re constrained by the physical materials themselves. To move forward, we must rebuild the foundation.”

At the core of the company’s commercial debut is a proprietary lowtemperature process that enables the direct growth of ultra-thin 2D materials, such as molybdenum disulfide (MoS₂), onto finished silicon wafers without damaging underlying circuitry. The resulting layers are atomically thin, low-leakage, and energy efficient, supporting dense vertical stacking and enabling new levels of integration.

While 2D materials have long held promise for next-generation chips, manufacturing and integration hurdles can slow adoption. CDimension claims its process overcomes these challenges with an Si back-end-of-line (BEOL) compatible approach that supports uniform, wafer-scale monolayer film growth across full silicon wafers, a key step in moving 2D materials from lab

10

December 2025

DFI DW 12-25 v5.indd 10

experiments to scalable commercial use. In internal testing, CDimension says its materials have demonstrated up to 1,000 times improvement in transistor-level energy efficiency compared to silicon.

“2D materials have enormous potential in many areas, especially for the semiconductor industry and future computing, and the development of successful wafer-scale synthesis is the key to unlock many of these possibilities for the future,” said Jing Kong, faculty member at MIT.

www.designworldonline.com

In addition to MoS₂, CDimension provides a full suite of 2D materials, including n-type, p-type, metallic, and insulating films, via a wafer-scale deposition process compatible with silicon manufacture. This allows integration with existing manufacturing workflows and forms the materials backbone of CDimension’s broader vision to unify compute, memory, and power in a single chip architecture.

Sustainability has become a strong driver of business value as pharmaceutical companies scale and localize operations. Digitalization works in tandem to enable sustainability-related business outcomes, especially in energy and power management, thereby driving efficiency and operational resilience.

1. Cost control. Digitally enabled energy management not only cuts carbon emissions, but it also significantly reduces energy costs. For example, with demand/response capabilities, new facilities can adjust power use in real time based on grid needs or price signals.

2. Business continuity. Power disruptions cost pharmaceutical firms millions in lost productivity and delayed customer commitments. A digitalized energy infrastructure strengthens operational resilience by improving power reliability and quality, thereby minimizing the risk of downtime. Technologies such as combined heat and power (CHP), solar, wind, and battery storage bolster energy security, and microgrid systems provide islanding capabilities that maintain production during local grid outages or fluctuations.

3. Time-to-market. Engaging partners early in the planning phase can significantly accelerate time-to-market.

For example, with tools such as Digital Twin, experts can simulate and optimize the plant’s power systems before construction begins, ensuring energy-efficient design from day one.

With rising cost pressures and renewed focus on U.S. manufacturing, leaders can also account for global export market expectations.

Design For Industry • MEDICAL

Ensuring polymer consistency at scale With global plastic production soaring to almost 450 million tonnes annually, slight variations in polymer quality can quickly cascade, leading to scrap, downtime, or even recalls.

Stephanie Williams, senior product specialist at Instron, states that melt flow testing (MFT), a precise “flow speed” test, helps ensure consistency and efficiency in polymer processing for medical device manufacturing.

During MFT, molten polymer is forced through a die under standardized conditions, yielding a melt flow rate (MFR) in grams per 10 min (g/10 min).

While high MFRs can ease mold filling and cycle times, they can also signal thermal degradation, especially in engineering materials such as polycarbonates or acrylonitrile butadiene styrene (ABS), risking weaker, crackprone parts. Conversely, low MFRs usually indicate stronger molecular chains but complicate processing due to higher viscosity and greater energy demand. For quality assurance, however, MFR can also reveal inferior or incorrect products.

MFT also aids production-floor quality control. For example, a medical device maker faced complaints about

hairline cracks in prefilled syringes after shipment. MFT confirmed the pellets used for the syringes met viscosity specifications and, therefore, the manufacturer had received the correct batch.

This knowledge enabled the company to shift focus to its production processes. Upon investigation, an unevenly heated cavity in an injection press caused poor flow and weak walls.

Without MFT, blame might have fallen on suppliers, leading to wasted material and regulatory issues. Instead, fast, consistent MFR results enabled targeted fixes and prevented costly disruptions.

Additionally, with sustainability goals now mainstream, compounders are increasingly using recycled or mixed-source polymers, with forecasts predicting the global recycled plastic market will reach $107 billion by 2032.

With this shift comes variability in composition and degradation, and makes ensuring consistent processing and performance more important than ever.

MFT offers a quick check. If a recycled HDPE batch shows an MFR of 25 g/10 min instead of the expected eight, it may indicate degradation or contamination. While MFT cannot identify exact chemistry, it can flag nonconforming batches before they reach production. For compounders, tracking MFR helps determine whether a batch meets specs, needs blending, or should be rejected.

With millions of tonnes of plastic produced each year, ensuring consistent polymer quality through melt flow testing is vital to reducing waste and preventing defects. DW Instron • instron.com

Precision technology for pouch-filling machines Speed is of the essence for packaging machines: Products must be filled, reliably sealed, and prepared for shipping in the shortest possible cycles. Ideally, maintenance and unplanned downtime are rare to keep the total cost of ownership low. The list of requirements is long and applies to the packaging machine itself and its components, such as the drive technology.

The Belgian company Scaldopack develops, produces, and services advanced spout-inserting machines and pouch-filling and sealing machines. The manufactured packages must be of very high quality, with a low error rate, stable production speeds, and high machine availability. At the same time, flexibility is also important, as their systems are converted from one batch to the next in a short time. Depending on the system and application, changeover times range from a few hours to less than 30 minutes.

Scaldopack uses Faulhaber BLDC motors in their machines, which operate around the clock, seven days a week. The direct linear drives with built-in Hall sensors enable a position accuracy of up to 0.1 mm with an acceleration of up to 4 g. This allows the machine to move pouches quickly and precisely to the proper filling position.

There, they are filled and sealed with the correct quantity, then stacked in displays for shipment or sale.

Because floorspace in production facilities is often expensive and limited, the systems need to occupy as little space as possible.

In the compact machine, the drive unit has a volume of 22 x 22 x 74 mm, achieves a peak force of 27 N, and can operate continuously for nearly three years without maintenance.

In addition to the drive’s reliability, system integration and machine operability are also DESIGN WORLD

DFI DW 12-25 v5.indd 13

decisive factors. The MC 3603 motion controllers perform the position control in the machines. Using standardized communication interfaces, such as RS232, EtherCAT, or CAN, control setpoints can be easily set, or the drive can be integrated into the automation system. In Scaldopack’s application, the motion controller’s CiA402 compatibility enables integration with the filling system's EtherCAT control system, simplifying integration

and required tests. This allows the company to optimally match drive systems and machines to achieve peak performance. The application makes clear what a decisive role dynamic, precise, compact, lowmaintenance, and easy-to-integrate drive technology plays in the automated packaging industry.

Electro-hydraulics solves liquid hydrogen pumping challenge

The energy industry has long considered hydrogen a promising, sustainable, renewable energy source.

However, the technical complexity of liquid hydrogen refueling challenges infrastructure designers seeking to match the operational speed and reliability of diesel systems. Bosch Rexroth’s CryoPump stations, unveiled at Hannover Messe 2025, introduce an electro-hydraulic solution that

14

addresses these constraints by departing from conventional crankshaftbased pump designs.

Developed in partnership with FirstElement Fuel, a California-based operator of commercial hydrogen stations, the system has two hydraulic stages, each with two hydraulic cylinders powered by electric motors.

operation. This direct-fill architecture streamlines the overall system design while minimizing potential leak points in the hydrogen pathway.

With a delivery rate of 600 kg/h, the CryoPump system can fill a Class 8 truck in less than 10 minutes.

Additionally, the system’s compact footprint of less than 11 m3 and noise level below 65 dB(A) enable integration into new and existing fuel station layouts, including residential areas. The design also incorporates AI-supported condition monitoring for predictive maintenance scheduling.

Plus, Bosch Rexroth claims that investment costs can be reduced by up to 50% by dispensing with highpressure accumulators and cooling power units.

“Everybody thinks it’s the cost of the molecule, that the hydrogen cost is high. That’s not really the case,” said Dave Hull, regional VP at Bosch Rexroth. “The equipment around the delivery of hydrogen is really immature, it breaks all the time, and it drives the operational expenses of your station really high.”

The CryoPump stations aim to address a fundamental infrastructure gap in hydrogen mobility by accelerating refueling, increasing profitability for operators, and improving the usability of hydrogenpowered commercial vehicles. DW

here are two types of servomotors commonly used for positioning motion control applications — the dc brush motor (which uses mechanical brushes to commutate the motor) and the brushless dc motor. The latter is also known as the BLDC motor or ac synchronous motor and is electronically commutated by external circuitry.

Unlike stepper motors that move in discrete position steps, servomotors

don’t have a built-in sense of where they are so need feedback (as from an encoder) to control position. A position servo loop drives the motor to a given position. It does this by comparing the target position from the trajectory generator at any given moment with the actual motor position and applying a continuous correcting motor command.

Consider the control-flow diagram for a general-purpose positioning www.designworldonline.com

servomotor controller. A host specifies high-level commands such as move from point A to point B using this set of trajectory parameters … then the motion controller’s profile generator continuously generates a commanded position input to the position control loop, followed by a current control loop and amplifier.

PID filter essentials In the PID position loop diagram the ‘loop’ part of the controller is the summing junction at which actual position is subtracted from commanded position to generate a position-error value. The PID part of the controller is actually a type of filter known (not surprisingly) as a PID filter. The PID filter takes as input a stream of position error values and generates as output a stream of commands to a current loop, or for some systems a velocity loop.

Tuning a position PID loop doesn’t require knowledge of how a PID filter is calculated, but the basic equation is shown below. This PID filter value (as well as its inputs) are updated and calculated at each servo loop update.

Modern motion controllers operate with servo loop update rates anywhere from 1 to 80 kHz with 10 to 20 kHz typical for general-purpose small-motor controllers sized NEMA 17 through NEMA 34.

control schemes, but the most common for motor positioning is the PID loop. Digital PID loop variations abound but are based on the simplified PID position loop.

A PID position loop is tuned by setting values for the proportional gain Kp, integral gain Ki, and derivative gain Kd which in turn determine their relative influence on the controller’s final output. In its basic form, the PID position loop only requires settings for these three parameters. That said, other commonly used settings are the integral limit, the derivative sample time, and feedforward gains.

AMPLIFIER

Where En = Current position error value; En-1 = Previous position error value; and Sum(En) is the sum of En values past and present.

A key reason that the PID position control loop is so widespread is that the effect of its constituent P, I, and D can be easily described and understood.

The P term is called the proportional term because it provides a proportional restoring correction to the amplifier output command. When presented with the position error the P term functions such as a spring. The larger the servo’s position error, the larger the corrective restoring motor command.

The I term is the integral (or integration) term because it integrates (over time) the servo position error. This is useful as a proportional term alone can’t arrive at the exact commanded position when subject to forces or mechanical issues such as gravity, stiction, and motor detents. The I term

crescendos over time and can get the servo surmount to the final target position.

The contribution of the D term is calculated by subtracting the previous position error from the current position error. It provides a feedforward boost whenever the profile velocity increases or decreases, and it provides a general purpose drag term to damp oscillations.

Industry staple: Step-response tuning The most common manual-tuning method to determine PID gain values is the step-response method or step response tuning. This approach leverages the reaction of the motor to an instantaneous (step) change in commanded position.

Manual tuning is relevant because many motion control vendors, in addition to auto-tuning tools, supply tools that help with manual tuning. After all, auto-tuners don’t always devise the best tuning values, and many autotuners don’t determine all the settings offered by a position loop. Of course, manually tuning a motor-driven axis is also a great way to get an intuitive feel P

for how changes to the P, I, and D gain values affect axis behavior.

To make step response tuning work, or for that matter any manual tuning method, we need a position trace facility to display the results of the moves. At a minimum we need to display a stream of captured values of the target position (commanded by the trajectory generator) and the actual position (as the motor’s measured location).

Consider the screencapture of such a facility — motion scope and trace software from one motion supplier. In fact, design engineers can use this software, similar products from other motion-control vendors, or even systems developed in-house.

Start with just the motor and go from there Once the motion controller as well as the motion trace and display software tools are in place, the actual mechanical system that will be tuned should be added. For most engineers the goal is to determine PID gain parameters that will smoothly and accurately operate the machine with significant stability margin.

In fact, this can be more complicated than it sounds because the axis and attached mechanisms being tuned may involve variable loads and operating modes.

So engineers should consider the specific operating condition of for which the controlled mechanism will be tuned. Often servomotor-system tuning starts sans load

or load mechanism. Tuning just the motor is a good first approach because from that baseline one can progressively add more realistic conditions. For example, after tuning just the motor one can connect the mechanism with no load, then one can add the minimum expected load to the mechanism, followed by the maximum expected load.

Having multiple PID settings for various mechanism configurations can also be useful in its own right. Many control systems apply different gain settings depending on the load or performance goal for a given operating mode. As we’ll explore, the PID gain settings that reach the highest end point positioning accuracy may be different than for those used to rapidly slew from one machine operating area to another.

Step-by-step PID-loop tuning procedure With capture and display software in place with the mechanism to be optimized, tuning can happen in five steps.

Step 1 is to setup the motion-trace capture facility. Different terminology may apply according to the vendor but in PMD’s

DESIGN WORLD

PMD has been producing ICs that provide advanced motion control of dc brush and brushless motors for more than 25 years. The supplier has also embedded these ICs into plug-and-play modules and motioncontrol boards. While different in packaging, all these products are controlled by C-Motion — PMD’s motion control language.

system one will set the trace capture system to trace Active Motor Command as the first variable, Commanded Position as the second variable, and actual position as the third variable. An optional fourth variable is position error, but defining this isn’t necessary for the procedure described here.

Step 2 is to setup the motion controller to make an ‘instantaneous’ step move from the current to a programmed destination position. Motion controllers from certain suppliers have a direct step-response mode that lets engineers simply enter the step distance. One caveat: The engineer may need to select a profiling mode (such as trapezoidal point-to-point) and program it with extremely large velocity and acceleration values, so the effective profile move time is close to zero.

One note when setting the step distance: During the step response move, the amplifier command shouldn’t go to 100%. Say the current limit for a given motor is 5.0 A and the controller is properly set so it doesn’t exceed that amplifier command value. Well, if the traced motor-current command reaches 5.0 A, the step distance should be lowered to prevent the servo output from being saturated.

This is an example of a system capture made with PMD’s ProMotion software.

Step 3 (for controllers with certain PID control settings) is to set the integral gain Ki, integral limit Ilim, acceleration feedforward gain Kaff, and velocity feedforward gain Kvff to zero. Proportional gain Kp is then set to a small value — perhaps 10 to 50 for motors

with quadrature encoders. Then Kd (derivative gain) is set to a value fivefold the specified Kp value. Finally, for small motors such as NEMA-17 motors, set the initial derivative time to 0.25 mSec; for NEMA-23 motors, set to 1.0 mSec; and for NEMA 34 or larger set to 2.5 mSec. Note that initial gain settings are controller-specific, engineers new to the controller will need to experiment. When in doubt, use lower values of Kp.

Step 4 is to execute the step move.

This should quickly spur the trajectory generator (in a single instantaneous step) to command a move having the programmed step distance. Assuming the trace function has been synched to the move start, a trace scope window will then display data. Adjustments to the data capture and scope display may be needed to get the full trace of interest on a single screen.

Uncontrolled motor oscillations mean Kp should be set to a lower value and DESIGN WORLD

Motion Control Feature DW 12-25 v2 Final.indd 25

Step 4 repeated. If at any point there’s concern that the motor or power supply is over-stressed, the controller should be disabled. If the motor produces a highpitched chatter or whine, KD derivative gain can be lowered or derivative time increased.

Step 5 is next once the position loop is at least somewhat stable. Then comes this repeating sequence: • View the scope display to determine whether the response is underdamped, critically damped, or overdamped (as described below).

• Adjust the gain settings accordingly.

• Make another step move (as in Step 4).

The next three sections will show one how to characterize the step move response and how gain settings should be adjusted.

typical underdamped response. The yellow trace shows that the commanded position instantly changes from a position of 0 to 100. With the software being used in this situation, this jump equals whatever the engineer entered into the step-response dialog box. The green trace shows the resultant motor location.

Though actual position does eventually settle to the commanded 100, it overshoots and oscillates several times. A system behaving this way is underdamped. To correct it, the design engineer should increase the derivative gain Kd. December 2025

Critically damped servo response curve: Now consider the screencapture of a plot of a critically damped response. In this trace the actual position doesn’t overshoot the commanded position, and it settles quickly (in 10 msec) to the commanded position of 100. Note that in these given trace displays, the unit of time is set to servo cycles. For the controller used in this setup, that’s 50 µsec per servo cycle.

It’s worth noting that many Kp and Kd combinations may spur a response that appears critically damped. In this manual tuning process, the distinction between critically damped and overdamped is somewhat subjective.

Overdamped servo response curve: Lastly consider a screencapture showing an overdamped response and compare it with the critically damped response. An overdamped system is stable but needlessly slow in its response to changes in the position command.

If the response is overdamped one should reduce Kd to the smallest value that still yields a critically damped response.

Setting the PID derivative sample time The derivative time setting is powerful. Derivative time is the period over which the PID loop derivative contribution is calculated in units of servo cycles or in milliseconds depending on how the controller is programmed.

Increasing the derivative time can be useful for reducing axis ‘chatter’ by effectively introducing a low-pass filter on the PID loop’s control response. This in turn allows the effective Kd damping contribution to be increased. Again, depending on how the controller functions the impact of the Kd on the PID loop command output is a direct multiple of the derivative time. For example, if the derivative time is set to 10 and the Kd value is 100 this would be an

equivalent derivative term impact as a derivative time of 5 and a Kd of 200.

Larger motors with larger loads will generally use higher derivative time settings and vice versa for smaller motors with smaller loads.

Experimentation is the best way to determine what values of derivative time and Kd gain give the quietest critically damped response.

Arriving at the final gain settings of Kp and Kd The main position-loop tuning goal is to set Kp as high as possible while still finding an associated Kd value capable of yielding a critically damped response.

Higher Kp values will spur more accurate tracking and faster responses to command position changes.

Trying higher and higher Kp values makes it clear at a certain point there’s no value of Kd and derivative sample

time that yields a stable and critically damped response. At this point one should reduce Kp by 35 to 50%, determine the associated Kd for critically damping, and use those settings as the final values for Kp, Kd, and derivative sampling time. Backing down from the ‘borderline’ Kp is key to stability, accommodating small controller and motor differences, allowing for attached hardware behavior, and handling system changes over time.

Setting the PID Ki gain and limit Once Kp, Kd, and derivative time have been set, one can enter a value of Ki (integral gain) to improve tracking accuracy. It depends on the controller scaling but typically Ki settings are a tenth to half the Kp value. Smaller motors typically use relatively larger ratios, and larger motors with larger loads typically use smaller Ki ratios.

Higher Ki settings increase tracking accuracy during and after the motor move is complete but can also reduce system stability. So, one should set Ki to the smallest value that can reach goals for tracking accuracy while not distorting the critically damped response the Kp and Kd settings created.

For most controllers the integral limit Ilim setting can be left at a very large value to effectively disable it as an integration-value limit. Most controllers including many position and velocity motion controllers have built-in anti-windup logic so it’s unlikely this integration limit will ever be reached. DW

The network protocol connects individual device data from sensors and actuators back to a controller. Because data from those sensors and other machine devices is key to automation, the data link is crucial to any successful automation strategy.

IO-Link basics IO-Link is an open standard, point-topoint communication link for sensors and actuators. It’s defined by the IEC 61131-9 international standard which specifies a single-drop digital communication interface technology (SDCI, commonly referred to as IO-Link) for sensors and actuators.

A typical IO-Link configuration includes an IO-Link master, which is the interface between the devices and a controller, such as a PLC. Devices can include sensors or actuators but can also be other devices such as hubs or robotic grippers or even power supplies with IO-Link connections. The master can be connected to virtually any fieldbus, and information flow between the master and devices is bi-directional. A key differentiator between IO-Link and standard IO is that with IO-Link, three types of data can be transmitted between the master and devices: process data, service data, and events.

What’s more, IO-Link is not a fieldbus itself.

Being fieldbus-independent, it can be integrated with and applied over various networks, fieldbuses, and backplane buses. IO-Link is a part of PROFIBUS & PROFINET International (PI), one of the world’s largest industrial automation organizations, where continued development includes IO-Link Safety and IO-Link Wireless.

IO-Link has a number of benefits that make it a viable alternative to other types of more traditional I/O setups, including reduced cost and complexity and improved efficiency. One such benefit is that it’s based on standard, unshielded, three-wire cables, so it eliminates custom cabling and connectors and simplifies wiring overall, particularly for analog devices. Plus, IO-Link relies on standards such as M12, M8 or M5 connectors, simplifying connections even further. And in case a device requires a power

connection, a standard 5-wire cable can be used.

IO-Link compares favorably with several types of networking setups, including analog and Ethernet-based methods. While many factories still use analog systems, these can suffer from data and accuracy losses during analog to digital conversion. IO-Link being entirely digital eliminates these losses.

With simple analog connections, there’s an advantage for IO-Link in that it can offer much more. While both are not complex to integrate with standard connections, analog connections lack the digital advantages of real-time diagnostics that IO-Link offers.

With IO-Link, real-time data can be collected directly from devices on the factory floor, providing data about pressure, temperature, and other parameters as well as diagnostic data about individual devices.

IO-Link also supports IIoT and Industry 4.0 initiatives by providing more data about devices and machines, which lets users perform real-time monitoring and diagnostics and make better, faster decisions. In particular, the bidirectional communication feature allows for extended diagnostics of sensors and actuators, and simple and fast parameter setup.

With the added data from factory-floor devices that IO-Link enables, manufacturers can more easily monitor machine performance to predict potential failures. They can also proactively schedule machine maintenance and reduce unplanned downtime to extend equipment and machine life.

Photoelectric sensors aren’t the only ones benefiting from IO-Link.

For instance, Hottinger Brüel & Kjær (HBK) has added IO-Link functionality to its T210 torque sensor to help engineers perform R&D and end-ofline torque testing more efficiently while streamlining their processes.

strain-gauge based, the shaft-style T210 is designed for integration into test benches, automation systems, or direct connection to the device under test. Its non-contact energy and signal transmission system ensures long-term reliability and high measurement precision.

Along with the new IO-Link interface, the torque sensor also includes voltage and frequency outputs for torque, speed, and angle, giving engineers flexibility across a wide range of applications, from development testing to automated end-of-line testing.

The future of IO-Link As the IO-Link organization reports, the long-term IO-Link strategy is based on further development of its range of technologies for opening up new application areas to both manufacturers and endusers. By enhancing transmission technology, IO-Link can also penetrate and open up new markets.

Enhancing data with precise time information is one such improvement.

Using so-called time stamps, sensor signals can be synchronized with actuator responses independently of cycle times in a highly precise way, for example. It will also be possible DESIGN WORLD

12/2/25 1:45 PM

to correlate measurement data from different sources for time-accurate evaluations. An example of this would be the multi-channel vibration analysis of machines. The goal is time accuracy of under 50 μsec, which represents a significant improvement over the cyclical transmission of 2 msec. Time stamps with an absolute time can be used for the time-accurate logging of events in the devices, for example.

Another building block for future growth is the ease of device use in the applications of machine and system producers. Thanks to profiles for different device classes, data models are being standardized and can also be used in a standardized way. Profiles for the smart lights, identification, smart actuators and smart power device classes are currently in the works.

Another key element of the IOLink strategy is the IIoT connection

of the IO-Link level to the world of IT. Successful JSON connection via the REST API will continue to advance MQTT support in an upcoming release, offering a streamlined, highly functional connection, such as to cloud-based monitoring services or asset management.

Lastly, there is the promise of IOLink Wireless. Wireless connectivity in general is revolutionizing industrial automation. It reduces cabling effort, lowers maintenance costs, and creates new freedom in system design.

The IO-Link wireless standard features a reliable, real-time capable and deterministic protocol that was specially developed for the requirements of factory automation. It enables the wireless transmission of signals from switching and measuring sensors as well as simple actuators. This is particularly advantageous for rotating

or moving systems where conventional cabling is impractical. Retrofits can also be implemented quickly and efficiently thanks to simple integration without point-to-point cabling. DW

WHAT ARE THE

THREE LEVELS OF

TEMPEST TESTING? Telecommunications electronics materials protected from emanating spurious transmissions (TEMPEST) testing, also called emission security (EMSEC) by the National Security Agency (NSA), is an NSA specification and is defined in the NATO SDIP-27 standard.

EMPEST is designed to deny unauthorized access to information derived from intercepting and analyzing unintended electrical signals, sounds, and vibrations emanating from electronic equipment, including computers, servers, telecommunications systems, cryptographic equipment, and similar devices.

The specific requirements of TEMPEST testing are classified. This article reviews Van Eck’s phreaking, called Van Eck radiation, which forms the basis of the threat that TEMPEST testing addresses. It also presents an overview of the three levels of TEMPEST testing.

Initially, phreaking was specifically referred to as hacking into a telecommunication system. Today, its definition has expanded to include hacking into any electronic system. www.designworldonline.com

Van Eck’s phreaking uses specialized equipment to attack the electromagnetic emissions of electronic devices’ side channels. While the U.S. government and Bell Labs knew about the possibility of phreaking as early as the Second World War, it was classified.

In 1985, Wim van Eck published the first unclassified paper on the security risks of unintended electromagnetic emissions. The paper described how to remotely reproduce the screen of a cathode-ray tube (CRT) display.

The emissions were captured with a specialized antenna to recreate the displayed images (Figure 1). The technique is not limited to CRT displays.

TEMPEST testing TEMPEST testing measures and analyzes the unintentional DESIGN WORLD

12/2/25 2:21 PM

electromagnetic emissions from electronic devices. It uses specialized antennas and receivers to capture the emissions and software to analyze the data and determine whether it can reconstruct sensitive information.

Most of the specifics related to TEMPEST testing are classified.

The three general factors include: • Distance is a critical factor determining signal attenuation, and TEMPEST testing is defined for 1, 20, and 100 m.

• Frequency range is important, and testing is conducted across various frequencies.

• Orientation is also considered, and devices are tested from various angles to identify potential emission locations.

NSTISSAM TEMPEST/1-92 from the

NSA details the TEMPEST laboratory test requirements for electromagnetic emissions. It defines three security levels and provides a certification framework for equipment and systems that meet the document’s standards.

NATO SDIP-27 also defines three security levels for electronic devices, which limit the electromagnetic radiation they emit to prevent eavesdropping. It also includes three NATO zoning levels.

Zones, levels, and ratings TEMPEST performance is defined by a series of zones and levels that lead to equipment ratings. The three basic zones and levels are (Figure 2): • Full is the strictest level of performance, which is called Level A by NATO and Level I by

the NSA. It applies to Zone 0.

It assumed that an attacker has almost immediate access to the equipment from 1 m or from a neighboring room.

Intermediate is called Level B by NATO and Level II by the NSA. It applies to Zone 1 and is designed to protect equipment from 20 meters of unobstructed distance and a comparable distance through walls and obstacles.

Tactical is the least strict performance and is called Level C by NASA and Level III by the NSA. It applies to Zone 2. This level protects equipment from 100 meters of unobstructed distance or a comparable distance through walls and obstacles.

lectric vehicles (EVs) are becoming mobile power stations capable of energizing everything from camping equipment to entire buildings.

Vehicle-to-Everything (V2X) technologies, including Vehicle-to-Equipment (V2E) applications, are changing how engineers design EV power architectures.

Bidirectional charging is the core concept behind these systems. This article examines the progress of bidirectional charging systems, including converter types and semiconductor advancements.

EV ENGINEERING

EV Supplement DW 12-25 v7 final.indd 37

What is V2X, and how does V2E fit?

V2X consists of five primary applications, including Vehicle-to-Grid (V2G), Vehicleto-Home (V2H), Vehicle-to-Building (V2B), Vehicle-to-Load (V2L), and Vehicle-to-Vehicle (V2V). Each places unique demands on the vehicle’s power architecture (Figure 1).

However, V2E/V2L stands out for its simplicity and practicality.

Unlike V2G, which requires complex grid synchronization and external bidirectional chargers, V2E operates independently through the vehicle’s

www.evengineeringonline.com

integrated power conversion systems.

V2X applications show multiple ways EVs can connect, building a complete ecosystem where EVs serve purposes beyond transportation.

The simplest entry into this ecosystem is V2E/V2L, which needs minimal external infrastructure and can power equipment or applications immediately (Figure 2).

V2E technology lets EVs power external devices and equipment with standard ac power through built-in inverters and outlets. EVs can now act as mobile power stations providing 2.4 to

How have EV power architectures evolved to support V2X? EV power architectures have changed significantly with the addition of V2X and V2E capabilities.

Earlier EVs had power flow systems that were only unidirectional and designed solely for propulsion.

Bidirectional applications, however, require more complex power

management. To be safe and efficient, these systems must handle energy flow in both directions.

Modern EV power architectures use multi-stage conversion, with each stage optimized for specific functions. As shown in Figure 3, the first stage typically uses an ac/dc converter that corrects power factor so EVs can charge from the grid. Dc/dc converters in the second stage manage the battery and stabilize voltage.

For V2E uses, an extra dc/ac inverter changes the dc voltage from the battery to a normal ac output. In this configuration, the vehicle can work as a power source on its own.

From an engineering point of view, this is where things get interesting.

Because of how complex the architecture is, converter topology design has come a long way.

Two-stage bidirectional onboard chargers (OBCs) are now common among manufacturers. These systems separate grid-interface and batterymanagement functions, allowing performance optimization in each mode.

Totem-pole power-factor-correction circuits and isolated dc-dc converters are typical, while dual active bridge (DAB) and CLLC resonant converters are the most common designs.

The detailed architecture of the bidirectional charger in Figure 4 illustrates its complex control systems that regulate power-flow direction, battery-charging profiles, and grid synchronization.

How do dc-dc converter technologies support V2E? As V2X and V2E capabilities have grown, they have sped up development in dc-dc converter technologies. Hybrid energy storage systems in EVs need complex power management. They must work together with different energy sources, like supercapacitors, main traction batteries, and other systems.

What does this mean for system designers? Because of this need, more advanced bidirectional dc-dc converter topologies have been used. These topologies make it easy for power to flow between different types of energy storage elements.

EV ENGINEERING

EV Supplement DW 12-25 v7 final.indd 39

This level of integration is an improvement over older charging systems that only worked unidirectionally.

It’s enabled safety protocols and power management algorithms required for V2X to work reliably.

A detailed classification of topologies shows the wide range of converter architectures used in EVs. It has become more popular to use non-isolated topologies like interleaved buck-boost

and three-level converters. They’re compact and efficient.

These converters lower the voltage stress on power switches and make the whole system more reliable. When galvanic isolation is required, isolated topologies offer higher safety and better voltage conversion. Dual active bridge and bidirectional forward converters are two examples.

Coupled inductors and soft-switching technologies have been added to make converters even better. They cut down on switching losses and current ripple.

These changes are especially important for V2E applications, where power quality and efficiency have a direct effect on the user experience and battery life in V2E systems.

Why have SiC and GaN become essential for V2X architectures?

Wide bandgap (WBG) semiconductors such as silicon carbide (SiC) and gallium nitride (GaN) have transformed EV power architectures. Compared to traditional silicon, they deliver higher breakdown voltages, superior thermal performance, and faster switching speeds, enabling compact and efficient bidirectional converters.

Over the last decade, these materials have rapidly replaced silicon in advanced two-way charger designs, establishing the foundation for next-generation V2X systems. As EVs evolve into integral parts of the broader energy network, these semiconductor advances will define the efficiency, reliability, and scalability of future electric mobility. EV

lectric vehicles (EVs) have rapidly digitized over the last decade, morphing into a complex web of software and hardware. Technology under the hood now spans lidar sensors, radars, driver assistance systems, and in-vehicle networks. The average EV runs 150 embedded electrical control units and 100 million lines of code.

These innovations are being integrated to improve vehicle performance and increase driver safety. However, while physical safety has benefited, connected cars present many emerging securityrelated threats.

As a result, cybersecurity is one of the top concerns of automotive manufacturers. Security impacts their bottom line in the form of cyberattacks, resulting in billions (yes, billions) of system downtime costs annually.

Software introduces new threat vectors As EVs become more intelligent and additional software is embedded, their vulnerabilities increase as cybercriminals gain a larger attack surface to exploit (Figure 1).

A couple of years ago, researchers identified several security weak spots that impacted 16 automakers. The flaws affected 20 different API endpoints, and if hackers had exploited them, they could have taken control of the vehicles, tracked locations, and accessed systems containing personally identifiable information (PII) of employees and customers.

Here are five critical areas of vulnerability that cybercriminals may target, as EVs become increasingly connected and autonomous. www.evengineeringonline.com

Over-the-air (OTA) updates and malware-infected apps can introduce vulnerabilities through wireless code updates delivered over Wi-Fi or cellular networks. This lets hackers inject malicious code, modify vehicle firmware, or alter system functionality unless the OTA process is protected with end-to-end encryption, authentication, and verification protocols (Figure 2).

Networked attacks exploit wireless, backend networks, and vehicle-toeverything (V2X) communications.

If successful, this tactic can impact electric car systems and disrupt traffic.

Securing messages transmitted by V2X communication channels remains a critical problem for the EV and the broader automotive industry.

prime targets. By intercepting and altering signals, bad actors can take over the EV’s controller area network.

If successful, hackers can affect braking and powertrain components, potentially causing sudden stops or acceleration.

Infotainment systems connect with a vehicle’s Internet and other devices via Bluetooth, cellular, USB, and Wi-Fi, creating potential entry points for bad actors. These systems contain personal information, such as payment details and location data, making them attractive targets for cybercriminals. Automakers can mitigate this risk by implementing strict access controls, deploying secure communication protocols, and using software and firmware to patch vulnerabilities.

Charging infrastructure is a major target for adversaries to install malware that can compromise a car’s safety and functionality. Hackers can tap into these public systems remotely or physically. In addition, EV supply equipment may be susceptible to malware attacks, threatening the integrity of the charging infrastructure and causing widespread disruptions in the power distribution system. Once compromised, bad actors can alter charging speeds, disrupt availability, or switch between alternating and direct currents.

Figure 2. Wireless code updates, often done via Wi-Fi and cellular connections, can introduce vulnerabilities that hackers use to insert malware into vehicle software.

Prioritizing cybersecurity Each point of connectivity is now a pathway hackers are eager to exploit.

However, despite widespread awareness of the risks, security is not a focus for EV manufacturers at the start of the vehicle design cycle.

Automakers must rethink this approach and identify and address vulnerabilities as early as possible. Every element requires testing, from sensors to software to telematics to charging infrastructure, to avoid costly delays and mitigate the risk of a successful cyberattack.

Once a vehicle is on the road, security testing can’t grind to a halt either. Every

software or system update requires the same rigorous evaluation to ensure it doesn’t introduce vulnerabilities. For example, each app must be tested before being integrated into a vehicle’s software system, and embedded firewalls should be integrated with firmware to provide reliable end-to-end encryption.

EV manufacturers must prioritize security and collaborate with all stakeholders to rigorously test for security vulnerabilities to ensure a safe driving experience. This will ensure that the technology transformation within the EV industry doesn’t provide an entry ramp for hackers to glide through and exploit. EV

leet electrification is often framed as a capital project: secure the vehicles, install the chargers, and you’re on the road to zero-emission operations. But the real work begins once the hardware is in place.

For many fleet operators, day-today operational complexity becomes the barrier to success. Ensuring vehicles are fully charged and ready to depart on schedule, managing energy costs, avoiding demand charges, achieving charger uptime goals, and maintaining healthy vehicle and infrastructure systems can quickly overwhelm teams.

When these challenges are worked through disparate platforms or outdated

tools, the impact can be profound, increasing operating costs and decreasing fleet reliability.

In this new landscape, systems must align across vehicles, grid capacity, utility tariffs, charging infrastructure availability, and cost. Artificial intelligence (AI) is beginning to emerge as the orchestrator that brings order to that post-deployment complexity.

A survey from logistics provider Penske revealed that 91% of executives understand the next generation of fleet and logistics professionals must be equipped with AI-enabled skills and tools.

transmit location and performance information), chargers, energy tariffs, and fleet operations, AI-enabled platforms can help managers and operators make smarter, faster decisions that improve reliability and reduce costs.

Let’s explore a few critical ways AI is expected to help address the most pressing challenges of post-deployment fleet management.

AI and human oversight: A formula for fleets Beyond the upfront investment in vehicles and chargers, one of the toughest ongoing challenges for EV fleet operators is ensuring each vehicle hits the proper state-of-charge (SoC) to match its daily route and duty cycle.

In conventional systems, this is a semi-automated process where planners estimate energy needs and schedule charging with limited data. Looking ahead, AI could dramatically improve this equation by automating route-aligned charging.

AI also has the potential to keep vehicles charged and moving with AIpowered predictive maintenance. This is becoming a must-have for modern fleets. EV chargers generate an enormous amount of operational data including charging cycles, fault codes, energy throughput, and environmental conditions.

With more data and time, AI could sift through this information to detect early warning signs and flag components or chargers likely to fail.

Not only that, but by pairing charging capabilities supported by AI with a humanmanaged Network Operations Center (NOC), operational anomalies could be minimized thanks to the two working in tandem. This enables fleet operators to act on insights from the NOC team, making adjustments that keep vehicles mission-ready and schedules intact.

In short, charging could be shifted to off-peak periods, infrastructure strain could be minimized, and vehicle availability maintained all without vehicle operator intervention.

Factoring in variables like climate, terrain, and battery health, AI-driven platforms will play a growing role in ensuring every vehicle is properly charged and ready to roll. Additionally, when a charger exhibits irregular behavior, AIenabled monitoring tools could correlate

Smart fleet management tools optimize charging schedules, reduce costs, and improve uptime.

that signal with other fleet-wide data and notify support teams.

Currently, this takes the form of automated alerts from monitoring patterns within the charging infrastructure, while the rest of the lifting — diagnosis, action, and resolution — is handled by trained personnel in the NOC, who can intervene before the issue impacts route readiness or delays departures.

While much of AI’s promise in fleet management is still developing, its influence is already evident in today’s EV operations. At one depot, for example, staff assumed a vehicle had been properly connected to its charger after a shift.

In reality, the plug was not fully engaged. Within minutes, AI-enabled monitoring flagged the issue, allowing the operations team to intervene and prevent what could have been a costly disruption the next morning.

In practice, predictive diagnostics could shift fleet operations from reactive fixes to proactive uptime management, keeping schedules on track and costs under control.

Turning data into savings Traditional charge management systems can help schedule sessions and monitor utility tariffs, but they often fall short when confronted with unexpected factors like weather disruptions, route changes, or equipment downtime. www.evengineeringonline.com

AI introduces an added layer of intelligence by going beyond static schedules. These systems can evaluate day-ahead energy prices, anticipate demand charge windows, and automatically shift charging to optimize for cost without sacrificing operational readiness.

The benefits only grow over time. With each data point, ranging from local climate patterns and driver behavior to rate variability and equipment performance, AI platforms continuously refine their models, uncovering new opportunities to improve efficiency. The result is a compounding effect: incremental adjustments today lead to accelerated gains tomorrow.

This means fleets can consistently minimize energy expenses while maintaining the confidence that vehicles will be charged and deployment-ready when needed.

This transition is already underway, as AI is helping fleets get ahead of problems, lower their TCO, and deliver more consistent, cost-effective service. The challenge for operators isn’t whether to adopt these tools; it’s how quickly they can start using them.

Essentially, the success seen by EV fleet managers won’t hinge on the number of chargers installed or vehicles deployed but on how seamlessly and cost-effectively fleets can operate every day after deployment. EV EV ENGINEERING

acemakers and implantable cardioverter defibrillators (ICDs) are small, battery-powered devices implanted under the skin to manage abnormal heart rhythms. Pacemakers deliver low-energy electrical impulses to treat bradycardia, while ICDs monitor life-threatening arrhythmias and deliver controlled, high-energy shocks. Despite their functional differences, both devices rely on specialized connectors and interconnects to ensure safe, long-term performance.

technologies. It covers legacy and emerging standards — such as IS-1, DF-1, DF-4, IS-4, and nanominiature connectors — and outlines typical lead and header configurations. The article also discusses reliability and system integration, detailing key design factors such as fixation, sealing, and conductor and insulator materials.

Pacemaker architecture and function As shown in Figure 1, surgeons implant compact, battery-powered pacemakers under the skin near the collarbone.

They regulate slow or irregular heart rhythms by delivering electrical impulses to the heart muscle. By supplementing or replacing the heart’s natural electrical signals, pacemakers help maintain cardiac output in patients with bradycardia, heart block, or other types of heart failure.

Most pacemakers comprise two main components: a pulse generator, which contains the battery and circuitry that control pulse timing and amplitude, and leads, which function as interconnects between the pulse generator and the heart, delivering electrical impulses and sensing cardiac activity.

Pacemaker leads typically incorporate MP35N alloy for the main conductor, selected for its mechanical durability and corrosion resistance. Manufacturers commonly use platinum-iridium for electrode tips, which provides excellent conductivity and biocompatibility.

Insulation materials such as silicone rubber or polyurethane offer flexibility and long-term biocompatibility.

During implantation, surgeons thread leads through veins into the heart under local anesthesia or sedation. Leadless pacemakers, used in patients requiring single-chamber pacing, are implanted CONNECTOR TIPS

Some pacemakers, such as biventricular devices, stimulate multiple chambers to improve synchronization in heart failure patients. Devices can also be programmed to adjust pacing based on patient activity level.

Pacemaker connectors and interconnects A reliable electrical and mechanical connection between the pulse generator and pacing leads is critical to ensure safe, long-term device performance. These connections must withstand continuous mechanical stress, fluid exposure, and electrical cycling over many years. To meet these requirements, pacemakers use standardized, medicalgrade connectors engineered for compatibility, secure fixation, and biocompatibility.

As shown in Figure 2, the IS-1 connector is the global standard for bradycardia pacemaker leads: It supports bipolar pacing with a 3.2 mm pin diameter and is typically secured in the device header using a set screw. The IS-1 specification enables interchangeability across manufacturers, simplifies replacements, and reduces the risk of lead-to-device incompatibility.

Hermetic sealing protects internal components by preventing moisture intrusion and pressure-related failures.

Engineers choose connector materials such as titanium and silicone rubber for their durability, corrosion resistance, and long-term biocompatibility within the body.

Other cardiac-related connector types include: • Nanominiature connectors are used in some compact or leadless pacemakers. They feature contact spacing as small as 0.635 mm and typically incorporate twistpin contacts and vacuum-sealed housings to resist corrosion, fluid ingress, and pressure fluctuations.

• DF-1 and DF-4 are used primarily in ICDs and cardiac resynchronization therapy defibrillators (CRT-Ds) for highvoltage defibrillation, not in standalone pacemakers.

• IS-4 supports leads with multiple electrodes, such as those used in cardiac resynchronization therapy.

They are rarely incorporated into standard pacing systems.

• SQ-1 is specific to subcutaneous ICDs (S-ICDs) and is not used in pacemakers.

ICD architecture and function As shown in Figure 3, surgeons implant ICDs under the skin in the chest.

It continuously monitors heart rhythm and delivers electrical therapy to correct life-threatening arrhythmias.

Depending on the severity of the condition, it may respond to ventricular tachycardia or ventricular fibrillation with either low-energy pacing or highenergy shocks.

Like pacemakers, ICDs comprise a pulse generator, which houses the FIGURE 2. The IS-1 connector interface between a pacemaker header port and pacing lead, highlighting the port end, setscrew mechanism, sealing components, and bipolar electrode configuration.

battery and electronic circuitry, and one or more leads, which function as interconnects between the generator and the myocardium, sensing cardiac activity and delivering electrical impulses.

These leads typically incorporate MP35N alloy for the main conductor, selected for its corrosion resistance, conductivity, and fatigue durability.

Platinum-iridium is commonly used at the electrode tips to ensure stable electrical contact with cardiac tissue. Insulation materials such as silicone rubber or polyurethane provide flexibility and longterm biocompatibility.

Many ICDs also offer pacemaker functionality, delivering low-energy pulses to manage bradycardia in addition to their primary defibrillation role. While both devices are implantable and used to manage cardiac rhythm disorders, their core functions differ: Pacemakers deliver low-energy electrical impulses to maintain a steady rhythm in patients with slow heartbeats.

ICDs detect and treat dangerously fast or irregular rhythms by delivering therapeutic shocks. These devices often include pacemaker capabilities as a secondary function.

ICD connectors and interconnects The electrical interface between the ICD pulse generator and its leads is critical for therapy delivery, safety, and long-term reliability. These connections must endure repeated mechanical stress, electrical

cycling, and exposure to internal body fluids over the device’s lifetime. To ensure optimal performance, cardiac-related connector designs have evolved to reduce procedural complexity, improve cross-device compatibility, and minimize implantation errors.

One example is the transition from the DF-1 connector, the legacy standard for high-voltage shock delivery in ICDs, to the more streamlined DF-4 connector. In a typical DF-1 configuration, the system includes one IS-1 connector for lowvoltage pacing and sensing, along with one or two DF-1 connectors for highvoltage defibrillation.

In some legacy systems, the ICD pulse generator case — typically made of titanium — also functions as an active electrode for defibrillation. This configuration results in a bifurcated lead structure, which increases system bulk and interconnect complexity, complicating implantation and replacement.

As shown in Figure 4, the DF-4 connector addresses these limitations by integrating both low-voltage (pacing/ sensing) and high-voltage (shock) functionality into a single, four-pole inline connector.

It uses one plug and a single setscrew to simplify the interface. The design incorporates four contact points — two for pacing/sensing and two for defibrillation — and places sealing rings in the device header rather than on the lead. This reduces mechanical wear, improves reliability, eliminates the need for a yoke, and lowers the risk of lead misconnection. As a result, DF-4 is now the preferred standard in most new ICD implants.

Other connectors used in ICD systems include IS-1, which remains in use for low-voltage signals in some configurations, often paired with DF-1 leads in older systems. IS-4 supports quadripolar leads for cardiac resynchronization therapy (CRT) but isn’t typically used in ICD-only devices.

Regardless of type, all ICD connectors and interconnects must meet stringent performance and reliability requirements.

Connectors require careful attention to fixation, sealing, and materials, while interconnects such as leads must provide long-term electrical integrity, mechanical flexibility, and biocompatibility.

ICD setscrews and spring contacts ensure stable mechanical and electrical coupling, while integrated sealing rings and hermetic housings protect against fluid ingress and maintain electrical isolation. Connector materials, such as medical-grade alloys and biocompatible polymers, offer corrosion resistance and long-term reliability within the body.

Pacemakers and ICDs rely on standardized connectors, hermetic seals, and biocompatible materials to ensure safe and reliable long-term performance. IS-1 remains the dominant standard for pacemakers, while ICD systems are shifting from the bulkier DF-1 to the integrated DF-4 connector, simplifying lead management and reducing complications. Additional connector types, such as nanominiature and IS-4, support specialized functions, including cardiac resynchronization and compact designs.

Bill Reese, general manager of accumulation and senior director of engineering for Columbus McKinnon, spoke with Packaging OEM about the new system, emphasizing that it was made possible through a collaboration within the Columbus McKinnon portfolio of brands. www.packagingoem.com

“We’re constantly trying to expand our product lines and find markets where we might have a solution but not the right product fit,” said Reese. “We teamed up with Dorner Manufacturing to develop the aluminum Bi-Flo to help us touch more markets that might be a bit more of an industrial setting where stainless steel is not required.”

Recirculation in a compact footprint The aluminum Bi-Flo uses a single motor to drive three modular chain sets in different directions, enabling product recirculation in a small footprint.

“Traditionally, you might have two, sometimes three motors on the system.

We replace those with one slightly larger motor to be able to take the load of the product and the chain,” said Reese. “It tends to be more energy-efficient because that single motor can run in its most efficient range.”

He added that this setup also eases integration, as it only requires one variable frequency drive (VFD). It also supports multi-line integration to merge or split product flow across lines.

The Bi-Flo can handle products from 1.25 to 10-in. in diameter or length, supports a maximum load of 500 lb, and has a top-of-chain height range of 20 to 60-in. The system includes safety features, including a pinch-free design and controlled flow with optional manual or automatic gates.

Adaptable for different line setups Garvey says the aluminum Bi-Flo can be configured in three ways to suit different

IT TENDS TO BE MORE ENERGY-EFFICIENT BECAUSE THAT SINGLE MOTOR CAN RUN IN ITS MOST EFFICIENT RANGE. packaging line needs, including: • One outfeed lane: Applied in applications where the product needs to be introduced to a line in a single file from a bulk station.

• One infeed lane: Designed for endof-line applications with inconsistent output to prevent backups.

• One infeed and one outfeed: Serves as an accumulation station to balance a production line and maintain throughput.

“It can not only act like an accumulation table, but it can almost act like a machine itself,” said Reese. “If you have a manual process where maybe on a smaller line, they’re manually placing products onto a single-linked conveyor and feeding them onto the line, you could put that infeed table at the beginning. It allows the operators to load the table up with maybe three, five minutes of product.”

With this method, labor is freed up so employees can pay attention to other parts of the line. “It’s not always about just throughput of the line, which you do get the benefit of that, but also making the employees more efficient on the line,” Reese said.

The company adds that the system provides optimized product transfer with flush side in/outfeeds and offers an optional nosebar for tight spaces.

Reese said the collaboration between Dorner and the wider Columbus McKinnon conveyance group allows Garvey to reach new customers in markets that previously required lighter-duty, nonwashdown solutions. OEM

CHALLENGE with bidirectional charging AS ELECTRIC VEHICLE ADOPTION ACCELERATES, VEHICLE-TO-GRID (V2G) TECHNOLOGY IS EMERGING AS A CRITICAL SOLUTION FOR MANAGING GRID STABILITY AND COMPLEXITY. MIKE SANTORA, MANAGING EDITOR OF DESIGN WORLD, SPOKE WITH DR. GRAHAM DUDGEON, PRODUCT MANAGER FOR ELECTRICAL TECHNOLOGY AT MATHWORKS, ABOUT THE TRENDS DRIVING V2G DEVELOPMENT, THE ENGINEERING CHALLENGES DESIGNERS FACE, AND HOW SIMULATION TOOLS ARE HELPING SOLVE THESE COMPLEX PROBLEMS.

DESIGN WORLD

12/2/25 2:59 PM

Design World: What are the trends driving demand for vehicle-to-grid technology, and how does it help utilities better manage grid complexity?

Dr. Graham Dudgeon: This is all based around the increasing number of electric vehicles that we’re expecting to be on the roads over the next decade or two. If we think about the battery on that electric vehicle only as a load — meaning that we need to charge it from the grid — then there’s a great deal of concern about the stress that might cause as the number of EVs increases.

But if we take a step back and think of that battery not just as being the primary way an electric vehicle is propelled, but also as a mini power plant that we can use to put energy back onto the grid, then we expose this potential value of having a virtual power plant enabled through all these vehicles, which we can coordinate to benefit the grid.

I'll give you one example of where that benefit might be. During a day, we typically have a peak demand on the grid, which may be problematic for the grid operator. The way I think about EVs at scale in coordination is we can mold or sculpt the grid response by adding and extracting energy.

By doing that, we can do things to help the grid by bringing down peak power. That would be one example of where vehicle-to-grid is beneficial.

DW: So, Dr. Dudgeon, what are the underlying mechanisms of bidirectional power converters that enable this two-way energy flow between EVs and the grid?

Adobe Stock

DESIGN WORLD

Mind Over Machine Supplement DW 12-25 v3 Final.indd 57

www.designworldonline.com

DG: The enabling technology of all of this is the bidirectional converter.

That’s a power electronic device which enables power to flow either charging the battery or to take energy out of that battery into the grid. Basically, it consists of power electronic switches — switches that turn on and off.

If we can control them appropriately, we can sculpt that electricity; we can change the voltage and the current.

One of the ways that’s important for V2G is changing the direction of the current flow, and that is enabled through digital control.

December 2025

12/2/25 2:59 PM

Mind Over Machine DW: So, the next question would be, how do you do it? From a design standpoint, what are the biggest challenges facing engineers in designing bidirectional charging for V2G systems?

“BUT IF WE TAKE A STEP BACK AND THINK OF THAT BATTERY NOT JUST AS BEING THE PRIMARY WAY AN ELECTRIC VEHICLE IS PROPELLED, BUT ALSO AS A MINI POWER PLANT THAT WE CAN USE TO PUT ENERGY BACK ONTO THE GRID, THEN WE EXPOSE THIS POTENTIAL VALUE OF HAVING A VIRTUAL POWER PLANT ENABLED THROUGH ALL THESE VEHICLES, WHICH WE CAN COORDINATE TO BENEFIT THE GRID.

DG: From my perspective, the primary challenge is what’s called design space. Let me explain what I mean by that. The range of possibilities in your design are very large. The engineer who designs that charger has to think about a number of things: voltage levels, current levels, normal and abnormal operating conditions.

What if a device fails? What if a power electronic switch fails? What does that mean for the overall response? Can we provide the power both supplying the battery and pulling energy out?

Can we provide that across all the anticipated ranges we expect, and can we also do it within the thermal constraints of our system as well?

The bidirectional charger itself and the battery management — that is a huge design space.

And when you get to the system level, it expands even further. Your options for design are enormous.

So, we have this concept of design space exploration: how do we explore the design space? We do that through simulation. By having simulation

models, we can set those simulations up to behave in the way that we would expect in real life and cover this design space. We can use parallel computing to help us, but overall, what we’re looking to do is build our confidence in the engineering design, and we use simulation as part of that.

DW: That brings me to my next question: what are the best practices for using simulation, advanced control design, and automated code generation to develop bidirectional power converters?

DG: At MathWorks, we do what we call model-based design. We provide tools that enable engineers to use simulation models at the heart of their technology development.

In late 2024, MathWorks and NXP Semiconductors released the Model-Based Design Toolbox (MBDT) for Battery Management Systems (BMS) to help engineers model, develop, and validate BMS applications.

DESIGN WORLD

12/2/25 2:59 PM

Best practices would be: form a simulation model at the earliest stage of your technology development cycle — the early stage being your eureka moment. When you have the idea, do something in simulation, get that idea down. And as that technology advances and develops, what you are doing is advancing that simulation model.

You’re basing your entire design off of that simulation model. It serves as a golden reference for other engineering teams. When control engineers come in to do control design, when systems-level engineers come in to look at the system, they’re operating off the same simulation model.

You can design controllers based on the simulation, but then when you are satisfied that your control systems are designed appropriately, you can automatically generate code, and that code will then go on the processors which are on your actual deployed systems.

The fundamental value here is: use simulation to unlock innovation and use it across the entire technology development cycle.

DESIGN WORLD

DW: I want to talk a little bit about some of the feedback you might be getting from your customers. What trends are you seeing with your customers who are developing V2G systems?

DG: We’re certainly seeing an increased level of interest from different industries.

We’ve got the automotive industry, power equipment industry, and utilities industry all looking at V2G, but looking at it from different perspectives.

I would say V2G is still in the emerging stage, where there’s a lot of exploration going on right now from an engineering standpoint. We’re seeing many customers developing the bidirectional converters and applying model-based design to do that.

We’re also seeing those organizations now starting to expand the value by looking at the system level — the energy management. They’re bringing other computational tools to the problem like optimization, statistics, and AI as well. They’re all coming to bear now in this emerging area. DW

Rapidly advancing technologies like artificial intelligence are revolutionizing how factories strategize, how goods move, and how high the efficiency bar can be raised. But for Emily LeVasseur, the selfdescribed “supply chain geek” and Co-Founder and Managing Director of Waypost Advisors, it’s the synthesis of human expertise and institutional knowledge with cutting-edge technology that will lead us into the future.

From the reality of AI-driven decision-making to the dawn of digital twins, LeVasseur details how manufacturers are leveraging data to transform the way companies handle supply chain management. The following is a condensed version of our conversation edited for length and clarity.

DESIGN WORLD

12/2/25 2:59 PM

Design World: Hi Emily! Thank you for being here. You previously mentioned the statistic that, according to the Data Manufacturing Institute, 97% of manufacturers are concerned about losing institutional knowledge as their workforce retires. The question is: how are manufacturing companies using artificial intelligence to capture this silent knowledge now?

Emily LeVasseur: Yeah, great question.

I can’t verify the 97% — I’m not aware of that — but what I can tell you is that the companies we work with, which are middle-market manufacturers across many different industries, are very concerned about it. In fact, I was just having a discussion with a data modeler about a project we have for a company whose production scheduling decisions are highly sensitive. They risk a lot of changeover loss and downtime if they don’t optimally schedule their production facility — and all those decisions go through one person who’s been there 25 years.

So this is a big concern. That person is starting to think about retirement, or even just how to delegate and democratize decisions. What we’re starting to see is companies asking: how do we use data, information, and AI to help democratize those decisions while keeping them as high-quality as possible?

Depending on your definition of AI — since we work primarily in supply chain, though that’s inextricable from production and manufacturing — AI means a few things. I think a lot of people think of ChatGPT or large language models, but in supply chain it’s really about data analytics and machine learning.

Large data models can bring in far more data than a human could process in a reasonable time, and they help structure decision-making so that outcomes can be presented as scenarios to a human decisionmaker. That’s where AI really shines.

We’re also seeing things like digital twins — which I think I saw an article about in Design World, right?

DW: Yeah, it’s a big part of what DW covers from the factory automation standpoint. It’s always on everyone’s mind.

DESIGN WORLD

Mind Over Machine Supplement DW 12-25 v3 Final.indd 61

EL: Exactly. The digital twin factory is really helpful because it generates so much data around the supply side. You can also bring in data from the demand side — orders, forecasts, macroeconomic trends — and combine it all to optimize inventory: having enough to meet demand, but not so much that you’re sitting on excess or obsolete stock.

DW: That’s such a good point. We frequently find ourselves at shows — IMTS comes to mind — and we hear people say, “We’ve collected mountains of data, but if we can’t analyze it and make it actionable, what’s the point?”

And hiring a data analytics team is expensive and time-consuming.

Especially with digital twins, I have this conversation constantly.

It’s interesting to see where AI might bring solutions for people.

EL: I absolutely think it will. Data is the unsexy foundation of all these powerful tools. I was talking yesterday to a woman who’s a data governance director at a large manufacturer in the Twin Cities, and she said it’s getting huge — because data is the fuel for the AI engine.

DW: Right.

EL: And one thing I’ll say — I’m super passionate about the supply chain planning function: demand forecasting, inventory strategy, capacity modeling. www.designworldonline.com

AI in supply chain focuses on using large data models and machine learning to process vast datasets and present clear, scenario-based decisions for human decision-makers.

Waypost Advisrors

It’s the mathy, sciencey side of supply chain. But those roles are probably the first ones that’ll be replaced by AI once companies figure out their data, because so much of it is math.

DW: Right. People avoid that topic, but it’s true. AI will integrate with many jobs and help people do them better, but we’re lying to ourselves if we think a few roles won’t disappear altogether. Once it’s cost-effective and easy to implement, those data-heavy jobs might go first.

EL: Yes. In a previous career, we had a team of 20 people doing supply and inventory planning. So much of that was just “plug and chug,” exporting Excel spreadsheets and doing analysis. You won’t need 20 people to do that once the AI systems are set up — you’ll need maybe two.

December 2025

12/2/25 2:59 PM

Mind Over Machine

Climate change, aging workforces, labor shortages, and strained infrastructure are converging to make the physical movement of goods one of the supply chain’s biggest ongoing challenges.

Waypost Acvisors

DW: Exactly — one or two people who know how to use and maintain the technology.

EL: Correct. And back to your question about losing institutional knowledge — the big thing is understanding how we make decisions, getting that tribal knowledge out of people’s heads, and democratizing decisions using tools.

DW: Yes, and that leads into my next question: what ways can AI capture and learn from essential institutional knowledge?

EL: I really think it’s through data analysis — especially if you can build a machine that continuously processes data and learns from outcomes. It takes time and investment to “teach” the system, but once you do, it can start making higher-quality decisions and reveal insights that humans might not have had the bandwidth to discover.

DW: Could you give us some real-world examples of manufacturing clients using AI? EL: Sure. This wasn’t one of our clients, but a company someone in my network worked with used AI to track and trend absentee rates at their facilities.

They correlated it with weather, local

62

December 2025

Mind Over Machine Supplement DW 12-25 v3 Final.indd 62

events, holidays, and more. Eventually, they could forecast absentee rates to 97% accuracy — which helped them plan temp labor better.

DW: That’s incredible.

EL: Yeah — it minimized throughput constraints and improved planning.

Another example: we worked with a company that was building a demand-sensing model to improve inventory management. They had a lot of “roving inventory” — stock in trucks or distributed across regions — and they wanted to use external data like weather and economic trends to predict where demand would rise. That helped them reposition inventory efficiently instead of stockpiling everywhere.

DW: So as a self-proclaimed “supply chain geek” (which we love), what do you think is the next big challenge for supply chains — and can AI help?

EL: That’s a big question. There are so many challenges. Climate change comes to mind — it’s going to impact infrastructure: ports, rivers, the Panama Canal, transportation routes. Physical movement of goods in a changing climate, plus labor shortage — that’s huge. www.designworldonline.com

Also, demographics — in the U.S. and China, populations are aging, and labor forces are shrinking.

Even if automation improves, the redistribution of workers doesn’t necessarily fill demand where it exists.

So, yeah. I think the physical movement of goods and infrastructure challenges will remain major concerns, especially with climate change and global instability.

DW: You’re absolutely right — climate change is already here for many, and we don’t have a clear path forward yet.

EL: Until we learn how to teleport food and goods, that’s going to stay a challenge. But I’ll put a positive spin on it: human ingenuity is amazing.

We’re adaptable. Whether it’s climate change, labor shortages, or supply chain disruptions, we always find ways to adapt. Yes, it’s going to cost more, and yes, it’ll cause short-term pain — but it’s also a breeding ground for innovation. DW

Technical Thinking

By Mark Jones

The fascinating idea of fast whiskey “Processed,” at least in front of food, is a dirty word these days.

Finding someone pro-processed food has proven impossible. “Fast” is similar. Put it in front of food and lots of noses turn up. I recently was introduced to processing that makes whiskey faster. In the case of whiskey, “fast” and “processed” aren’t bad.

The history of how “processed” became derogatory eludes me, as does exactly what processed means.

There was a time where preservation and making food nutritionally dense were considered positive technical advances. I discovered a site ranking foods on a 0 to 10 scale of processing. The more I look at it, the more confused I became. When first confronted with a text box for entry of a food, I thought I would try for a 10 with Pringles. Completely uniform potato chips in a can surely were surely processed. Nope, dead middle of the scale at 5. Flavor on chips, even seemingly natural sounding salt and vinegar, by this site’s measure, pushes up the score. I have a book describing the science that went into the creation of Gatorade. Science

be damned, it ranks a 10 for being a processed food, higher than the artificially sweetened electrolytes. The scores aren’t at all intuitive. I’m left uncertain of what processed means and whether it should be derogatory.

In the case of something that is already highly processed, like whiskey, more processing may be okay. All whiskey is clearly processed. The malting, mashing, and distillation are all processes. No one complains.

I am a whiskey and bourbon novice, but that’s changing thanks to a local fundraiser with a bourbon focus. The most recent event introduced me to Cleveland Whiskey and its process for duplicating whiskey aging in days rather than years. Increasing temperature and pressure bypasses long barrel aging. Barrels still are needed to call the whiskey bourbon, but stainless-steel vessels and toasted wood chunks do the heavy lifting for some of the whiskeys. Medals adorn Cleveland Whiskey bottles, proving processed whiskey can be as good, maybe better than traditional methods.

Much about bourbon is about tradition. Rules limit what can be

called bourbon. Composition of at least 51% corn is one. Aged for at least two years in new, charred oak barrels is another. Pictures on the Cleveland Whiskey site show barrels in spite of using a process to avoid barrels. The barrels aren’t needed for flavor, only to match rules to be called bourbon. Barrel aging is a science all its own. The charring of the inside is a processing technology of uncertain origin. It plays a significant role in releasing flavors from the wood, the flavor in the finished whiskey.

Aging is costly. Barrels add cost, but that’s minor and they are also the source of bourbon’s distinctive flavor.

The business cost is the working capital tied up during aging. The ingredients and labor are paid for long before the whiskey can be sold. Tom Lix, the founder of Cleveland Whiskey, developed a pressure-aging process to accelerate aging with pressure.

He learned to make bourbon fast.

There is a lot of prior art detailed in his patent. Along the way, he discovered that the process allowed flavoring with other woods, other ingredients that couldn’t be made into a barrel. Use of maple, apple, and cherry wood gives flavor profiles previously impossible to realize.

Cleveland Whiskey is innovating to make better whiskeys faster. Unlike fast food, fast whiskey can be good, even medal winning. All whiskeys are processed. Adding more processing brings benefits. At least for whiskey, processed isn’t a bad thing. DW
