Losing weight

www.design-engineering.com Publisher Alan Macpherson (416) 510-6756 AMacPherson@design-engineering.com

L

ocked away under three bell jars in the temperature and humidity controlledvaults of the International Bureau of Weights and Measures (BIPM) in Sevres, France, lies one of the most pampered and influential objects in civilization—a hunk of platinum and iridium forged over 130 years ago following the French Revolution.

Called the International Prototype, or IPK for short, this slab of metal is the quintessential kilogram that defines the SI unit of mass. As such, all scales and thereby weight and mass measurements are based on it. In fact, many of the basic units that describe the forces of nature are tied to its exact value.

The only problem is, it’s been getting steadily lighter. No one knows why, but when the quintessential unit of mass was compared to official copies of itself, none of the values matched. Most importantly, the IPK was found to be lighter to the tune of a whopping 50 micro-grams or approximately the mass of a fingerprint.

Considering how little the IPK is off its original value, it may seem that somebody should just plant their thumb on the thing and have done. However, the fact that its mass is actively changing wreaks havoc with other SI units that depend on it. For example, the measurement unit of force, the newton, is defined as the “oomph” needed to accelerate one kilogram at one meter per second squared.

Complicating matters is that other units, including the pascal (pressure), the ampere (electrical current) and the joule (energy) are tied to the value of the newton.

In turn, the joule is used to define the watt. As a result, changes in the value of one kilo, however small, cascade through most all other measurement units.

Since the kilo is the only SI unit defined by a physical and apparently unstable object, the international metrology community is looking to redefine it based on a fundamental constant of the universe, like the speed of light. In the Kilo’s case, it’s Plank’s constant which describes the relation between the momentum and the quantum wavelength of any particle.

However, nobody’s absolutely sure what that exact value is either. To help settle the matter, two methods of nailing down Plank’s constant have been proposed. One would use a special scale called a watt balance that measures the electricity needed to resist the Earth’s gravitational pull. The second, called the Avogadro Project, involves precisely counting atoms in the world’s roundest ball of pure silicon.

Unfortunately, experiments using both methods have come up with results that diverge by around 175 parts per billion. For the fastidious metrologist who oversee such things, that’s too much. However, in an uncharacteristic “laid back” manner, a former head of BIPM’s mass division has proposed that the two numbers be averaged to arrive at a final value. Not surprisingly, many of those involved in the controversy don’t relish the idea of adding the kilogram to horseshoes and hand grenades in the expression about “close enough.”

Whatever method is ultimately used, the final definition of the kilo is expected to occur in 2015 when the international General Conference on Weights and Measures next meets. Along with the scientists whose job it has been to babysit the IPK, I can wait. In the meantime, I can enjoy the fact that I’m just that much lighter.

SolidWorks 2012 and Beyond Solidworks provides a peak at its future directions and latest software release.

By Ralph Grabowski

A

t the end of August, Solidworks flew in a select group from the CAD media to get a preview of the then soon-to-bereleased Solidworks 2012. To my disappointment, the day was narrowly focused on Solidworks 2012 and so ignored other products, such as the wildly successful DraftSight and the upcoming SolidWorks V6.

Bertrand Sicot is the new CEO of DS SolidWorks, and this was his first chance to describe for journalists his vision for the company. He wants both he and his employees to listen, keep it simple, keep users first, work on evolving the software and not start a revolution, invest in the channel (dealers or resellers) and extend the market for professional CAD. He understands that the company exists only because of customers, and so he expanded on each of his points. As an example of listening, he wants 90 percent of new functions to be useful to all users, not just 10 percent. It is easy to make software complex, he said. Instead, he wants he wants to simplify it, so it works the way users expect it to.

“We are in the market where things are changing, but we are not in a revolution; the technology we use is changing,” he said. Perhaps he said this to calm those upset by statements made in previous years about the revolution in switching SolidWorks to the Cloud.

I found his aim for extending the professional market for 3D interesting, because he listed the following fields: AEC,

medical, high technology, industrial design, manufacturing and consumer product development. But there were no further details provided.

I did get a chance to ask an executive what had become of the Cloud, and why we were not hearing any more about it. It is now known as SolidWorks V6, because it is based on Enovia V6, the parent company’s collaboration software. (The executive called the current desktop version “SolidWorkd V1.”)

To my surprise, the V6 software hasn’t entered beta testing yet, even though its development by now is stretching out to five or six years. I asked if V6 would be full SolidWorks or a subset, like AutoCAD WS. The executive indicated it would be a subset with the tools most often used by those people would are likely to use SolidWorks on the Cloud. He reiterated that desktop SolidWorks would be developed for as long as there was demand for it on the desktop, which to my estimation is “forever.”

I also found it interesting that other V6-based software, such as the oddly named and heavily promoted n!fuse file sharing software, is now being treated as test software, something for which DS SolidWorks is taking feedback to determine future development.

The biggest number thrown out at the media event was 1.6 million; SolidWorks is now running on 1.6 million computers, although 1.1 million of them are educational seats.

Still, the educational number is significant, because SolidWorks charges for them, unlike, say, Autodesk and Siemens PLM, who hand them out for free.

SolidWorks 2012 As vice president of product development, it was up to Felder Hiss to introduce us to the 20th release, SolidWorks 2012. He did so by first running through its history, release by release.

The company began under the name Winchester Design Systems, and today it is a “brand name” of Dassault Systemes, arguably the largest CAD company in the world.

Then we were given 1.5 hours of demos by Mark Schneider and Ian Hogg, who showed us some of the 200 or so enhancements. Of them, perhaps the most interesting is the new Costing Tool – and the one of which users will say, “What took so long?”

Costing is common in AEC, but no other MCAD package incorporates it. Even so, it came Solidworks 2012’s eagerly awaited Costing Tool lets engineers determine the cost about almost by accident. A few releases ago, impact of design choices in terms of component pricing and cost to manufacture.

SolidWorks incorporated an environmental October | 2011

11-10-12 12:12 PM

CADReport 15 calculator that determines the impact proposed designs have on pollution, transportation and other environmental “costs.” But how about practical costs, such as the cost to manufacture?

The costing module was mocked up, and then demo’ed to dozens of customers before going into beta. DS SolidWorks wanted to make sure the process of determining costing would work the way customers expected. What you get is the ability to see the effect of different manufacturing techniques and materials, and segregate parts between those that can be bought and those that must be made.

Running through some of the other new features I thought are pretty good: Large Design Large Design Review allows for quickly view very large assemblies. Through it, users can Review is a way to view huge assemblies instantly; highlight, hide or inspect individual components and load related parts for editing. you can now load related assemblies by rightclicking parts. Also, balloons have magnetic lines, so they act Previously-loaded files can be pinned, so that they are easy like groups. Feature freeze was supposed to make it into an to find and reload. Finally, during continuous dimensioning, earlier release, but finally appears in 2012; this command lets you can press Esc to go back one step.

DE you determine which features should not regenerate. www.solidworks.com More important to me are the little improvements that help every day drafting, such as command search.

Creo Hands-On Nearly a year after PTC announced it would change CAD history, how does Creo 1.0 deliver?

By Ralph Grabowski

A

Installing Creo Installing Creo is much like other software, with one exception: The license server. The server software installs on your computer, and it determines whether you are allowed to run the software. Some customers experience no problems; others have problems, as I did.

The server works by tying the Creo license(s) to your computer’s CPU serial number and monitoring the network card every few minutes. In my case, the serial number I received was incorrect, preventing installation. Tech support guided me through the multi-step process for applying for a new license from the PTC website.

Days later, Creo balked at running when I reopened the lid of my notebook computer, waking it from sleep. Because Creo could not communicate with the license server, it asked if I wanted to save my work before it exited. Problem was, it would not let me save. Tech support advised me to use Task Manager to stop the license server service (lmadmin_ptc), and then run the ptcadminstartservice.bat file to restart it. (The batch file is in C:\ Program Files\FLEXnet Admin License Server\bin.) Tech support and I continue to work at finding a better fix to the problem.

year ago, PTC generated much speculation with ads that claimed its new software would get us all “out of CAD jail.” When unveiled, we learned of newish software and a new name: Creo, it was explained, means “create” in several Latin languages.

Creo is a second restart for PTC, the company that ignited the parametric and history-based CAD design in the late 1980s.

The first restart was named “Wildfire,” in which Pro/E was tuned for Windows and the Internet.

When PTC renamed its CAD software “Creo,” it confused people into thinking this was new software. In the weeks that followed, PTC had to explain that Creo was only the beginning of a rewriting its old software.

“Keep in mind, what we announced in October [2010] was a vision and strategy for the future of [our] CAD,” explained Mike Campbell, PTC’s divisional VP of design and visualization products on the Deelip.com blog. “What we delivered in Creo 1.0 is the first step on the path toward that vision.”

The renaming even extended to the venerable Pro/Engineer Wildfire software, confusingly renamed “Creo Elements/Pro”. Now, the re-name goes by simply “Creo Parametric.”

As well, the company’s direct modeling CoCreate software was renamed “Creo Elements/Direct Modeling.” This software shouldn’t be confused with “Creo Direct,” a smaller scale direct modeling package Figure 1: Creo Direct moves and deletes parts of developed on the Granite kernel and assemblies imported from other CAD systems. purpose built to partner with Creo Parametric. PTC’s non-CAD software, such as Arbortext and MathCAD, did not get the Creo label.

(See http://www.ptc.com/products/ creo/product-mappings.)

When it comes times to decide on licensing Creo from PTC, you have the two same choices, Creo Parametric (i.e., Pro/E) or Creo Elements/Direct (i.e., CoCreate); everything else is a module that you call from one of these two, such as Figure 2: After drilling down in the feature tree, Creo sketches, layouts and simulation.

Direct fully edits imported parts in a separate window.

Pairing Parametrics and Direct When PTC launched Creo, their aim was to solve “four unaddressed problems” in the MCAD space: usability, interoperability, assembly management and technology lockin. PTC provided me with Creo Parametrics and Direct for me to check out their claims.

Usability: Besides a new name, the Creo line of software sports the now-common ribbon user interface and a softer blue-green color scheme.

Opening either Creo Direct or Parametric brings up the new ribbon interface along the top, and a not-new integrated Web browser in the drawing area. The ribbon is meant to make it easier for new users to find commands, because, as one oldtimer put it, “In Pro/E, you could find any command—in seven mouse clicks.” For power users, the old Mapkeys facility continues to work. www.design-engineering.com

Technology Lock-in. PTC’s ideas on solving technology lock-in don’t match mine.

To me, we should be able to move our drawings to (and from) any CAD package, keeping in mind the limitations of translation.

In addition, PTC boasts of its many translators for importing models and drawings from comHydraulic pumps and motors • Valves • SAHR brakes petitors’ systems, so that you don’t need to Wheel drive units • Control systems • Power units be locked-in with them.

Q&A with Solidworks CEO Bertrand Sicot I

n August, Design Engineering had the opportunity to sit down with Bertrand Sicot, CEO of Solidworks, at the grand opening of Javelin Technologies’ new headquarters in Oakville, Ontario. During the interview, the young, affable executive spoke eloquently about his first year in the top spot and his vision for company’s future.

DE: Now that you’ve served your first year as CEO, what are you’re impressions?

Sicot: For the business, I would say that it is good to be back at a normal speed again. After 2009, 2010 and 2011 have been much better. The business side is very strong everywhere in the world. For the job, it is exciting because I’ve been with the company since day one. I joined Solidworks back in 1996 so I’ve seen the small Boston company grow into a large corporation with a large community of users. In my new job, it is a mixture of managing the short-term, which is delivering

what the company has to deliver, and also looking to the future and making sure we are well positioned for the next three to five years.

DE: What are the goals for the next three to five years?

Sicot: We have to start with the users; this is really what matters. There are a few trends you will see happening in the market. The first one, I believe, is mobility. I spoke with a group of end customers this morning and four of them were carrying computer tablets. Customers are asking us to provide solutions to help them get access to their engineering data wherever they are. The second trend, platform neutrality, is a consequence of first. The solution has to be platform neutral where it is not a question of the device being iPhone or Android OS-based. Users don’t care if they are using technology A, B, C or D; they only care if they can access their data.

DE: Technically speaking, what is the future for Solidworks the software; will it become more tightly integrated with Dassault Systemes’?

Sicot: We have said that we are working on the next generation of Solidworks, which means that all options are on the table.

Dassault Systemes is a large group with a lot of clever engineers and we are going to take the best technologies that are available from the group. At the same time, it is one thing to think about the future, but we need to deliver a solution that fulfi lls users’ needs. That’s the critical part, because today we can have a lot of proof of concept prototypes but that isn’t the solution. The technologies are changing but we will put a full solution on the market when it is ready.

DE: Solidworks 2012 is nearing its launch. As an engineer yourself, what excites you about it?

Sicot: There is some great innovation in it. We have worked not only on the functionality but also the performance again and again because we know this is what customers are interested in. We have made some good progress on that.

For myself, there is one thing I feel is new. When you design a product, you end up making a series of decisions that lead to

So what we are trying to do is to give the engineering community tools so that they understand that, if they go this way or that way, they will know what the price impact will be on producing a part or assembly. At the end of the process, users will be able to compare the options, because today, designers are blind to the cost side of what they are doing.

This is somewhat similar to the sustainability tool that we have that lets engineers understand the carbon footprint or certification implications for that product. Like sustainability, this new tool pulls data from outside so users can compare but I think costing is very good one because the user community is much more sensitive to costing than sustainability so far, especially given the state of the world economy.

DE: Solidworks is regarded as the plucky entrepreneurial upstart whereas its parent, Dassault Systemes, is a large corporation.

Do you foresee Solidworks’ culture changing over time?

Sicot: Today, we are a bigger group, a bigger company with more than a 1,000 people. So what was obvious 10 years ago, because we were smaller, can be a little bit hazy today because

we are a larger group. We have to keep things simple. I hate complexity. I’m always looking at ways to keep things simple and that is a challenge for a company or organization that is growing. As to the company culture, it comes from the top, and that is why I’m here. I am and will be an accessible CEO and my executive team is accessible because it is all about people first. So the tone and the mind set of the company are not changing.

DE: Solidworks founder Jon Hirschtick spoke at a Javelin event a number of years ago and now you’ve come up for the company’s new headquarters opening. Besides the fact that it’s the leading Solidworks VAR in Canada, what makes Javelin Technologies special?

Sicot: John [Carlan] and Ted [Lee] started Javelin way back in 1997. At that time, it was a risk to bet on Solidworks and start a company that depended on a small start-up from Boston delivering a promising solution called Solidworks.

Together, we have had a lot of successful business but, 14 years ago, they shared the same dream with us. They started in their garage, and when I joined Solidworks in Europe, I started in my bedroom. Look where we are today. We must be doing something right. The goal is to continue.

Molding the sets of resin samples presented a whole new set of challenges. The first molded prototype for the sample stars addressed general design issues. These included adjusting clips on each chip; orientation of the “keys” on the chips; adjustments to draft; positioning of the parting line around various features; and adding fillets to make parts “touch friendly”.

Once these general issues had been addressed, some of the resins presented their own issues. This came as no surprise since the six resins—ABS, acetal, polycarbonate (PC), thermoplastic elastomer (TPE), glass-filled nylon (PA-GF) and highdensity polyethylene (HDPE)—were chosen specifically for their differences.

like a lot of prototypes, but every additional step produced significant improvement in the final product. We were able to get real parts into a lot of people’s hands and get real feedback instead of just guesses.

DE Kevin Crystal is a Senior Engineer at Proto Labs. He was also the lead engineer on Protogami, as well as a number of other Proto Labs design aids.

Production Challenges The unavoidable mix of thick and thin areas in the star presented some challenges. Gate sizes had to be adjusted for each resin to ensure proper mold filling. Of particular concern was the “break me” tab, located downstream of a hinge on each star. Because resin had to pass through the thin hinge to get to the tab, poor fill and resulting shrink could have been a problem.

In each case, the designer used standard hinge parameters as a starting point, but adjusted thickness as required to allow the tab to fill. Similar revisions were required for some of the sample inserts. Published manufacturer’s shrinkage specs were used to machine the mold, but fits varied from ideal to so loose that chips fell out of the frame. For those inserts that required modification, careful planning allowed the changes to be made by modifying molds rather than remaking them from scratch.

Over the course of development, we made a total of 21 different machined and molded prototypes. By working out most of the major design issues using inexpensive machined prototypes, we were able to reduce the number of molds we had to make for prototyping. In several cases we were able to modify existing molds to accommodate changes, and all the molds that produced our final prototypes are now being used for production. 21 may seem www.design-engineering.com

I

n engineering research, detail is vital. Researchers must not only develop models quickly, but they also require in-depth analytical tools to help them understand, on a fundamental level, the intricacies of their models. Researchers at many academic institutions have adopted MapleSim, advanced physical modeling software from Maplesoft, as a key tool in their engineering research activities.

One of those researchers is Dr. Amir Khajepour, Professor of Engineering in the Mechanical and Mechatronics Engineering Department at the University of Waterloo, who has used Maplesoft technology in his research projects over the past 10 years. Recently, Dr. Khajepour used MapleSim as part of an ongoing project with the Canada Space Agency, to develop a solution for the power management system of autonomous rovers.

“The benefits of MapleSim compared to traditional tools are significant,” said Dr. Khajepour. “We now have the mathematical model of the six-wheeled rover without writing down a single equation. MapleSim was able to generate an optimum set of equations for the rover system automatically which is essential in the optimization phase.”

Dr. Khajepour first chose Maple, Maplesoft’s advanced technical computing software, while working on a research project to develop and solve the equations of motion for a standard delta robot. From this work, Dr. Khajepour developed the DeltaBot. Capable of handling up to 20 kg, the DeltaBot robot uses cables instead of rigid arms to reduce moving inertia and mechanical equipment costs. Based on commercial demand, Dr. Khajepour established AEMK Systems, a company specializing in the design and distribution of high-speed, cable and vision-based robotics systems for use in a variety of industrial applications.

Force Feedback Similarly, Dr. Venkat Krovi Director of the Automation, Robotics and Mechatronics (ARM) engineering research lab at the State University of New York (SUNY) at Buffalo uses Maplesoft software in his robotics research, haptic user-interface design and real-time simulation and control of engineering systems.

One of his research projects involved the study of kinematic and dynamic simulations of 6 degree-offreedom Prismatic-Universal-Spherical (P-U-S) type manipulators. A October | 2011

parallel manipulator combines a platform that moves and a fixed base, interconnected by several legs.

He and his team then worked with Markham, ON-based real-time control systems designer Quanser Consulting Inc. to create a specialized version of a parallel manipulator.

Using Maple and MapleSim, Dr. Krovi and his team were able to obtain the optimal geometrical parameters for the specialized 6-DOF P-U-S system. The motion platform, termed the Hexapod, is now part of Quanser’s mechatronic controls collection.

Another of Dr. Krovi’s research projects at the ARM Lab, completed in cooperation with Quanser Consulting Inc, involved the design and analysis of in-parallel haptic devices.

As part of this research, Dr. Krovi and his team, and Paul Karam, director of engineering at Quanser, developed the system-level kinematic model of an in-parallel haptic device, using the symbolic computing techniques in Maple and MapleSim. Using this approach, they were able to generate the relevant symbolic equations for the system, and a combined symbolic and numeric analysis of the system performance.

“The resulting symbolic equations helped to identify singularities, perform parametric design refinements and improve the real-time model-based control strategies,” said Dr. Krovi.

Engineers at the University of Waterloo used MapleSim to develop a full solution for the power management system of robotic space rovers for the CSA.

Automotive Modeling As NSERC/Toyota/Maplesoft Industrial Research Chair for Mathematics-based Modeling and Design at the Waterloo Centre for Automotive Research, Dr. John McPhee is responsible for research efforts focused on producing new methods for modeling physical systems.

Current engineering practices create computer models that are numerical in nature, to explore different design concepts and evaluate their performance.

McPhee and his team are collaborating with experts at Maplesoft and Toyota to develop these mathbased models and computer simulations, with a focus on automotive applications such as vehicle dynamics, powertrains and hybrid electric vehicles.

Together with Dr. Thanh-Son Dao and Mr. Aden Seaman, McPhee also conducted research involving batteries for hybridelectric vehicles. The development of such vehicles is a significantly more complex task than designing conventional cars because they incorporate many different engineering domains into a single system.

One of the most important components of an electric vehicle is the battery itself. The team is currently working to develop high-fidelity models of hybrid-electric and electric vehicles, including the batteries. For battery electric vehicles, they designed a math-based model of a complete battery pack

in MapleSim, along with a simple power controller, motor/generator, terrain and drive-cycle. The resulting differential equations were simplified symbolically and then simulated numerically with physically consistent results. For hybrid-electric vehicles (HEV), they developed a multi-domain model of a series HEV using MapleSim, including an automatically generated optimized set of governing equations.

The HEV model consists of a mean-value internal combustion engine, DC motors driven by a chemistry-based NiMH battery pack and a multibody vehicle model. As a result of MapleSim’s lossless symbolic techniques for automatically producing an optimal set of equations, the number of governing equations in both models was significantly reduced. “We firmly believe a math-based approach is the best and quite possibly the only feasible approach for tackling the design problems associated with complex systems,� Dr. McPhee said.

Smooth and Quiet “The stepper motors were so quiet that I thought the machine wasn’t running,” says Matthew Dunne, President of Align-Rite Tool Company. Align-Rite makes a broad line CNC routers and mills plus other tools used by fabricators in the woodworking, jewelry, metalworking and solid surface industries.

“One of the reasons we’ve switched to Testra’s SoftStep drive systems is that you get really accurate, very quiet drives compared to other ones,” Dunne explains. “It also allows you to cut faster because the drives virtually eliminate the vibration, so you get a much smoother movement on your X, Y and Z axes.” Dunne adds that his customers are satisfied with the SoftStep drives that are installed on Align-Rite’s wood routers because it is capable of going faster with smaller bits with greater accuracy. Also, with the vibration problem removed, there is much less a tendency to break bits.

“When you get down to some of our smaller bits – people doing the pool cue inlays and things like that – you have to have a CNC router that can run at a fairly high speed, but very smoothly,” he says. “For applications such as jewelry or where you have expensive Corian inlays you must have a very smooth stepper system so that you don’t have any chipping from vibration. Also, our high-end cue builders need to have a seamless inlay on their cues.”

he affordability and reliability of step motors – “steppers” – has made this technology highly popular among many industries, ranging from electronic printers and disk drives to aircraft controls and many CNC applications. One of the major reasons for this is the application of microstepping drives, which have improved the smoothness and accuracy of the step motors.

Yet, for many users, such as manufacturers using CNC equipment, the microstepping technology still has some conspicuous drawbacks. Despite technology already on the market, step motors are still subject to vibration, noise and harmonic resonance issues because of the way they are driven. Even today’s microstepping motors can break tooling when operating at higher speeds, and often have chatter problems that create flaws when cutting arcs or circular shapes.

Those drawbacks have largely been overcome with the development of “SoftStep” microstepping, a technology that can virtually eliminate noise and vibration that have been problematic in the past.

NCR Canada’s Director of Engineering Susan Carreon displays her team’s Scaleable Deposit Module, an ATM that simultaneously accepts bills and checks for deposit.

Cashing in New Canadian technology makes ATM line-ups a whole lot faster.

By Treena Hein

B

anking took a giant leap forward when the ATM appeared; their ability to get cash out and put cheques in anytime was a huge hit. When on-line banking came on the scene, banking again became more convenient, but ATM’s were still needed.

However, when a person has to deposit a bunch of items at once at the ATM, it can take quite a while. That’s why a team at NCR Canada in Waterloo Ontario, headed by Director of Engineering Susan Carreon, has developed a new ATM that allows consumers to rapidly deposit an assortment of up to 50 banknotes and cheques all at once, no envelopes needed. It’s been welcomed by U.S. banks and will be arriving in Canada soon (after enabling legislation is passed).

When dollar bills and cheques are fed in, the NCR ‘Scaleable Deposit Module’ separates each item, straightens it so the best image can be taken and then passes it through camera and sensor arrays.

“If it’s a banknote, the technology determines the denomination and checks security features,” says Carreon. “If it’s a cheque, the machine ‘reads’ the magnetic codeline at the bottom and the handwritten amount.” The system then displays cheque images, along with a summary of the cash deposit and total deposit for the consumer to confirm. This same information, including thumbnail images of cheques, is provided on the receipt. The whole process for an average deposit takes under 60 seconds. www.design-engineering.com

35-DESv1.indd 35

The NCR scanning system is a two-sided full colour image scanner with specialised magnetic, transmissive and invisible spectrum sensors for currency and cheque validation. Errors occasionally can happen, but they’re prevented in several ways.

“The first is the ability of the consumer to review and correct the deposit on the screen,” notes Carreon. “If the handwriting is too messy, the system will display the image of the cheque and prompt the consumer for the amount.”

If the bills or cheques are in very poor condition, the system will return them. “Occasionally, the system can jam on damaged items, and in that case, the ATM will automatically send for service help,” adds Carreon. The other failsafe is in the bank’s final processing, where cheques and currency are cleared and any discrepancies picked up on.

Carreon says that, although they’ve been working on cheque processing technology at NCR Waterloo for almost 40 years, it’s only been in the last seven years that the technology has been inexpensive and reliable enough to be able to adapt it to an ATM. Among the many challenges involved, two stand out.

“How to create a system that physically handles cheques is something we had a lot of experience with, but building one that can handle cheques and banknotes intermixed was tricky,” she says. “Cheques are made of stiff paper, and dog-ears and creases are common, so the transport mechanisms have to be able to overcome that. Dollar bills, especially older ones, can be very soft, and that requires different handling. We had to devise mechanisms that could manage both.”

The second challenge was quick recognition. “There’s a lot of processing that has to go on in a very short span of time to gather and process all the images and sensor data from the note or cheque; be able to decide which it is; denominate and validate the notes and read the amounts on the cheques; and then move the items to the correct location inside the machine,” Carreon says. “If the transaction time took a lot longer than the current envelope deposit system, there wouldn’t be any point. It was one thing to get quick processing in place, but the technology also had to be inexpensive and reliable enough.”

Overcoming these challenges requires a highly multi-disciplinary team, which Carreon loves leading. “The mechanics, electronics, firmware and software required to make this system work are tightly interconnected and we’re constantly discovering new ways to make the system better,” she says. She also thinks it’s fascinating to see new types of currency and different features and to stay on top of ways to process them. “We have so many ideas on how to make the SDM faster, more reliable, cost-effective and globally-applicable,” she says. “I don’t think we’ll ever stop innovating.”
