Renesas’ speedy recovery from quake is “miraculous” The earthquake and subsequent tsunami that rocked Japan’s coastline on March 11th of this year literally shaked the foundations of Renesas Corporation’s Naka fab, producers of 70% of the world’s microcontrollers supply.

Built to withstand ‘8’ on the Richter scale, the facility suffered from such extreme damage, experts projected a minimum 6 to 9 month recovery plan. In a recent interview with Ali Sebt, COO of Renesas Electronics America and Kevin Simmonds, president of Canadian operations, the firm’s return to normal operations 3-months sooner than expected was simply “heroic and miraculous”.

This was achieved through effective planning, teamwork, help from partners and customers, capped by a “monumental amount of dedication, sacrifice and communication,” Sebt says. Roughly 80,000 people contributed to the company’s recovery on a global basis, including 2,500 external employees, all of whom shared a sense of urgency and optimism from the beginning.

“The biggest surprise and the most gratifying thing for me was the groundswell of support Renesas received from its own employees, customers, suppliers, contractors and even competitors,” he adds. “It was clear to me that these people were determined not to let this earthquake stop us from succeeding.”

In the early stages of the disaster, news reports kept North Americans abreast of recovery efforts in Japan, and Renesas customers were very understanding to delays in the supply chain of their ordered MCUs, according to Simmonds.

“For the first couple of weeks, our Canadian customers were very understanding,” says Simmonds, who received updates via daily teleconferences from corporate HQ. “This was no small sacrifice for some of these customers, as Renesas’ products impact 70% of their revenues. Everyone understood that it was not our fault. In the end, we’ve come away with stronger customer relationships.”

During our telephone chat in September, Sebt said he expected Renesas would be close to 100% capacity by this month and likely exceed its production capacity in November. Ensuring future stability, Sebt walked me through Renesas’ New Business Continuity Plan, which focuses on strengthening and prioritizing a stable contingent product supply for customers.

“Over the course of time, the whole supply eco-structure will morph to reflect a similar strategy, thus providing redundant supply sources,” he says.

Truly a testament to teamwork and dedication, Renesas’ rebuilding story has provided our industry with an amazing example in courage and learning from adversity -- sometimes with unexpected benefits.

Renesas is now also sharing a YouTube video that details its rise from the depths of disaster, candidly detailing the rebuilding process. It can be viewed at http://www.youtube.com/ watch?v=Vwkdf7j65IQ Stephen Law, Editor slaw@ept.ca Follow me on Twitter http://twitter.com/#!/EPTmagazine

Avnet and NXP host USB workshops

Quebec tech groups strike strategic partnership

Avnet Electronics Marketing Americas Inc. recently teamed up with NXP Semiconductor recently to host its Speedway Design Workshop - USB Made Easy.

Featuring hands-on labs with Avnet’s team of field application engineers (FAEs), the seminar demonstrated how to develop USB applications based on NXP’s fully scalable Cortex-M USB portfolio. This Speedways (pictured here) was held recently in Mississauga ON, along with multiple cities across North America.

Featuring NXP’s low cost LPCXpresso development platform, the course explored how NXP microcontrollers are making the task of developing USB enabled devices faster and speeding time to market. The LPCXpresso labs focused on the Cortex-M0 LPC11U00 and pin-to-pin compatible Cortex-M3 LPC1300 microcontroller series. This device is the latest addition to the Cortex-M0 family, providing a highly configurable, full speed USB 2.0 device controller; bringing unparalleled design flexibility and reliable USB connectivity for consumer electronics and mobile devices.

“USB is quickly becoming the main ‘communication protocol of choice’ for most applications,” says Shelley Carpenter, marketing manager for microcontrollers at NXP Semiconductor. “This training shows customers how easy it truly is to implement USB in their solutions with NXP’s technology.”

Aiming to become the definitive voice for the electronics industry within Quebec, two industry related associations have formed a strategic partnership in hopes of better showcasing the technological developments within the Province.

Quebec’s electronic industry association or RIE (Regroupement de l’industrie électronique du Québec) recently announced its official affiliation with VERi-T, specialists in commercial project management & business development for high tech companies.

Working synergistically through collaborative partnerships, the group intends to promote regional high tech activities to a global audience, according to René Boutin, RIE business development manager.

“The electronic industry has changed dramatically in past years and we have witnessed OEM’s and developers working very hard to keep their business position,” says Boutin.

“Now is the time to share that experience to the world and demonstrate the benefits of local innovation built in recent years in Quebec.”

Marking its 10th anniversary this year, RIE was originally established to act as a liaise or industry representative to government authorities and a bridge to educational institutes and businesses.

“RIE also offers support through its technical, commercial and other industry related activities,” adds RIE president François Verdy-Goyette. “We want to make people aware of these activities, many of which are planned over the next few months.”

Among recent activities included a conference and dinner (in French), which featured speakers: Gilles Gagnon, vice-president business development at R2G2; and Walter Poggi, president of RETLIF. Earlier this month, another conference & dinner was held at the same location under the title of “WorldWide open markets... could globalization be reversed?”. The event was led by guest speaker Yves Lusignant, president of Ciblexpert.

In past articles, we have looked at various infrastructure support that exists for the high tech industry, and how we need to strengthen our emerging technologies and encourage enterprise. This is exactly what the Alberta Centre for Advanced MNT Products (ACAMP) aims to deliver to its technology clients, providing access to world-class equipment, facilities, expertise and a network of organizations that support and develop micro and nano technology devices, advanced materials and manufacturing worldwide.

I recently had the chance to speak with ACAMP’s CEO, Ken Brizel and CFO Rosy Amlani, about the not for profit organization’s services in support of the commercialization of Alberta-based tech products.

What is your niche – what size companies do you serve?

ACAMP is a manufacturing and development organization, with experts recruited from all over the world. The group’s primary interest is to help small and medium enterprises (SME) build their businesses and take their technologies to market, according to Brizel.

“We focus on design for manufacturing and developing products for real market opportunities,” says Brizel. ACAMP’s services encompass key areas identified as critical for the commercialization of MNT products - marketing & business development, product development, packaging and assembly, test and characterization.

What makes ACAMP so successful?

Brizel says when he joined the firm in the summer of 2008, ACAMP had its first five clients, which were board members. Today, it has 85 active clients and about 40 that they are engaged in talks with.

“Our model is quite unique in North America, you won’t find another ACAMP. Our approach is real world help, we are not academics. We have all come from industry with between seven to 30-years of experience,” adds Brizel.

Any words of advice for a budding tech entrepreneur?

“Stick to it, don’t give up, network globally and build for real market opportunities,” Brizel says.

The element14 knode

Engineering design information to a web-connected world

By Jeff Jussel, senior director of global technology, Newark/element14

Electronic system design requires engineers to gather information for many different technologies from many different places. So where is the best place for an engineer to find all this information?

That is the question that Newark/element14 set out to answer when it commissioned a study by Technology Forecasters Inc. (TFI) focused on the key challenges faced by design engineers in improving electronic system design efficiency. The results of this study, released in September 2011 show an opportunity for an independent, web-based source of technology solutions and design information to address the needs of design engineers.

The scope of the TFI study covers the external information gathering needs for design engineers throughout the entire design process, from initial specification and technology research, through detailed design, prototype testing and evaluation, and finally to engineering release and production.

The study surveyed engineers across the globe in big and small companies, and asked them where they spent their time searching for information, which information was the hardest to find, and about their perceptions concerning the value and quality of the information they found at those sources. The study was conducted both through written surveys and through many phone conversations with engineers around the world.

Not surprisingly, the study found that most of the time spent searching for external technology information was spent during the early stages of the design process. This makes sense, as it is during the initial conceptual design, and detailed implementation stages that engineers are most likely to need external technical information. In these initial stages of the design process, the designer is often left to single-handedly gather information from a variety of sources. Ideally, the experienced engineer will have a set of “go-to” places to search for information – and indeed the survey found that seasoned engineers were somewhat less likely

Source: Technology Forecasters

to encounter difficulties and delays in this information gathering phase. Yet, even the experienced designers spent unproductive weeks during this process – exposing a big opportunity for improvement to the design process.

In a typical design process, the electronic design engineer begins by researching the technology; including gathering information about design protocols and standards, learning about existing architectures, and discussing possible new approaches with experts in the field.

In today’s world, the starting point for this search is usually a general purpose search engine like Google. Unfortunately, while a Google search will return thousands of items on a term like ‘Zigbee,’ it will probably add days to the engineer’s workload to sift through the results to find the relevant technical data. Further, engineering research also requires digging through dozens of vendor web sites to search for the latest product information, each with different structures and data formats.

“Unfortunately, while a Google search will return thousands of items on a term like ‘Zigbee,’ it will probably add days to the engineer’s workload to sift through the results to find the relevant technical data” The element14 knode provides an engineering-focused search tool that helps speed up and simplify electronic engineering design research by consolidating relevant technical information into a single learning center and combining it with technology forums for connecting semiconductor supplier experts and engineers with similar design interests.

The next step in the design phase may include testing potential technologies for their performance and suitability to the application. For hardware analysis, an engineer can use a development platform as an “instant prototype” of a portion of the design. A single resource for all development kits, arranged by application type and by supplier, can help accelerate the design process by defining the right parts for the system. Similarly, system software can be prototyped using off-the-shelf software elements for specific applications. Engineers download trials for real-time operating systems and software stacks to evaluate different implementation options. By finding compatible application software and hardware solutions together

in one location, engineers can devote more time to adding differentiating features to their systems rather than debugging interfaces between vendor products.

instance, pricing and availability might be found on a distributor site, but unbiased product reliability data, or long-term endof-life information about a component may be more difficult to find. In fact, the bias of a vendor web site, along with the skewing of product specification data is one of the biggest concerns facing engineers making component purchasing decisions.

In some cases, the component datasheet may show best-case specification numbers for every design constraint (e.g. power, voltage, current), making the component described by that datasheet a device that could never exist in the real world. Other suppliers may show only the most pessimistic numbers for the same device, making valid comparisons almost impossible without doing weeks of laboratory testing. A single, unbiased source of comparison data can help replace the ubiquitous spreadsheets that engineers produce for every new project.

Finally, the study explored the many sources where engineers find their design data and compared the advantages of the addition of an independent source as a place to start design research. While most design searches begin with Google as a neutral starting point, the huge volume of information returned is problematic, as is the possibility of the right data being hidden behind thousands of irrelevant search results.

Vendor sites by contrast, yield accurate component data, but TFI’s survey revealed concern regarding vendor bias in any comparison data. New social media sites such as forums, communities and blogs are another possible source of data, however engineers have concerns over unknown levels of expertise or bias in anonymous posts. The strategy for element14 is to provide a new credible alternative for engineers as an independent source of engineering design information and solutions.

The results of this study highlight the opportunities to advance the design process and design engineer’s overall productivity via a web-based design knowledge-base that gives engineers consolidated design resources, increased collaboration with peers working on similar stages of the product design lifecycle, and access to reliable search sources.

Designing embedded systems with Wi-Fi connectivity

T

Today Wi-Fi products can do everything from sending email to streaming audio and video— linking users to the Internet from their home, office, coffee-shop or even from a plane 30,000 feet in the air. All this is essentially enabled today by the Wi-Fi connection on laptops and mobile phones.

The next wave of Wi-Fi applications will likely be driven by the integration of Wi-Fi into embedded systems—the billions of dedicated electronic systems that run on microcontrollers. The applicability of robust wireless local and Internet connectivity provided by Wi-Fi has prompted a rush of Wi-Fi integration into embedded systems. These systems are the heart of a broad range of devices in various vertical segments, including healthcare, industrial, automotive, smart energy and smart buildings.

In this article, we will cover the integration of Wi-Fi connectivity into an embedded design and discuss come of the challenges and benefits of doing so and how to overcome those challenges.

Wi-Fi’s original intention was to provide wireless extension to data oriented Ethernet. The software protocol is designed to work as a layer-2 network interface. The Wi-Fi protocol is sophisticated and typically has a requirement to run a Wi-Fi driver on a host processor with a minimum size of 100KB. Integration of these complex Wi-Fi drivers typically requires long design cycles and expertise in Wi-Fi. Embedded systems are characterized by limited computing resources with limited host memory. They perform dedicated functions like interfacing to sensors or peripherals. They are characterized by a variety of micro-controllers ranging from 8-bit versions, with a few kilobytes of instruction memory, low-speed serial interfaces UART/SPI to 32-bit higher-end versions with SDIO/USB interfaces. Most embedded systems run a simple RTOS or no operating system at all; a host microcontroller may not even have TCP/IP on it.

Embedded Wi-Fi poses multiple challenges such as seamless ease of integration, how to future proof Wi-Fi on

resource constrained systems and shorter design cycles. Moreover, embedded systems demand wireless devices that offer ease of integration, little or no load on the host microcontroller, low power operation, low cost, quick wake-up from low power modes, small footprint, and guaranteed interoperability in current or future wireless network scenarios. Their users also wish to be free from demands associated with wireless engineering.

The integration of a Wi-Fi interface into these systems should not only have a minimal impact on the system configuration and resources used, but also on the design methodology itself. Embedded users are acquainted with tool-chain and development environment of microprocessors. If Wi-Fi can act as a peripheral to microcontroller platforms providing an option of ready-to-use starter kits with fully compiled libraries integrated to development environment, it will also provide an excellent starting point for a large number of embedded system designers to “Wi-Fi” their products.

Embedded Wi-Fi block:

Figure 1 shows a WLAN subsystem integrated into the embedded system. The microcontroller’s UART or SPI interface is used here to connect to the WLAN module.

Interfacing a WLAN subsystem to a microcontroller-based device requires considering several factors including the physical and electrical specifications, choice of interface, host load, the software architecture, power-save mechanisms, wireless configuration, wireless performance, and certification. We look at these below.

Fully integrated self-contained Wi-Fi modules or integrated chips require a single 3.3V supply and provide a simple external interface consisting of the antenna and the host-interface. High levels of integration, with on-chip DC-DC, zero-host-architecture and power-amplifier integrated into the RF. The choice of host interface is generally made from one of several low-power interfaces including SDIO, SPI, and UART. The modules are FCC/IC/CE certified and enable modular certification for the systems into which they are built-in. Self-contained WLAN modules are usually calibrated during manufacture, and the software controlling the device would use the calibration data during normal operation. Using pre-calibrated wireless modules helps avoid the complexity and cost of calibrating an assembled embedded system during its manufacture.

Software architecture is an important aspect of the integration of a wireless LAN into an embedded system.

Figure 2 shows the typical complete software stack related to data transfer over 802.11 Figure 2: Software components of 802.11 wireless data transport WLAN. This software

option is used when a host microprocessor has an operating system and has the capability to handle a Wi-Fi host driver.

On the other, most embedded systems are based on low-end microprocessors with no operating system or TCP-IP stack capability.

Ease of deployment: Embedded Wi-Fi modules are sometimes integrated into end devices that lack a display/keyboard to configure the wireless link (e.g., security password and other link parameters). This limitation can be overcome if the end device has a serial or USB connector; in that case, the link can be configured through that interface. In a few embedded systems (e.g., wireless tags) the provision of that connector would violate the system form-factor— in such cases the “wireless” configuration mechanisms have to be deployed.

One of the possible implementation could be to have the embedded Wi-Fi device put to a factory-reset state, starting with a default configuration. New credentials like SSID, passphrase for new connection are wirelessly transferred through a configuration application running on a laptop or a smartphone.

Proof for long-life span: Embedded systems (wireless thermostats, sensors, etc.) demand long-life span. Wi-Fi technology evolved from 802.11b in 1997 with a migration to 802.11g in 2003 and then to latest state of the art 802.11n technology in 2009. Designing an embedded system with future proof technology like 802.11n is a very important design consideration. The following are a few advantages of 802.11n devices over legacy 802.11b/802.11g Wi-Fi devices: 1. Future-proof without cost overhead Single antenna 802.11n incurs zero cost-overhead over legacy 802.11b or 802.11b/g solutions and future-proofs the Wi-Fi system.

2. Lower power The higher available data-rates (up to 65Mbps) enable smaller durations for packet transfers and hence less time spent in “active” mode, thus reducing average current consumption. In-fact single-antenna 802.11n solutions transfer 20x more data than 802.11b solutions and 2x more data than 802.11g solutions on the same battery.

3. Better coexistence Increasingly, 802.11n embedded systems are deployed into enterprise and commercial 802.11n networks. These networks use Wi-Fi for voice, video and other quality-of-service intensive applications. Legacy solutions, especially 802.11b solutions, disrupt such networks since they use the same wireless medium. In addition to this, 802.11n access-points use ‘legacy protection’ mechanisms in the presence of legacy 802.11b or 802.11g solutions.

Legacy solutions affect the network throughputs and quality of service.

4. Higher throughputs Due to higher PHY data-rates and advanced MAC mechanisms including packet-aggregation and block -ack to reduce overheads, singlestream, 802.11n implementations can achieve 40-45Mbps of host goodput.

This is almost double compared to legacy 802.11g implementations.

5. Higher range STBC in the down-link (AP to STA) and MRC in the uplink (STA to AP) enable 6-9dB better performance in multipath for single-antenna 802.11n stations over legacy 802.11b and 802.11b/g stations.

Wi-Fi starter kits: Wi-Fi Starter and evaluation platforms provide a user-friendly introduction of embedded Wi-Fi modules, for example Connect-io-n modules from Redpine and its integration with MCUs from leading vendors (Atmel, Cypress, Freescale, Renesas,etc). These kits include an API library to control and configure the Wi-Fi module, sample code, and easy-to-use demo applications integrated to MCU software/hardware tools.

This approach makes the integration of Wi-Fi connectivity into an embedded design as easy as using any peripheral on microcontroller and aid penetration of Wi-Fi connectivity to billions of embedded devices.

Medical Electronics

Opening up A NEW WORLD of TREATMENT

I

In recent years, there has been great excitement about the use of neuromodulation to treat a wide array of medical conditions and diseases. The technology uses electrical signals to stimulate or block different nerve impulses in the body and is adapted from technology used in cardiac rhythm management. It holds promise for a variety of conditions, including reducing or eliminating back pain, curing obesity, lowering high blood pressure and controlling diabetes without daily injections of insulin.

Advanced ceramic materials are playing an important role in the technology and are poised to play an even greater one

as these medical devices flood onto the market to treat an increasing number of ailments. Ceramic-to-metal brazed assemblies for hermetically sealed electrical feedthroughs, piezocomposite materials that facilitate ultrasonic device communication and biocompatible ceramics as an alternative to titanium device casings, are just a few of the ways that advanced ceramics are playing a part in enhancing this technology. These ceramic materials and technologies play an important part in developing new and innovative treatment methods that were simply not possible with traditional materials.

Implantable pulse generators ‘stimulate’ medical device industry

ceramic composite materials and assemblies, as well as high pin density feedthrough assemblies, is being pursued to enable a next generation of neuromodulation devices that will provide better treatment, improved patient safety and convenience, and better communication with other devices.

Bacteria-inhibiting film impedes harmful growth on medical devices A duo of high-tech firms have collaborated to develop a groundbreaking bacteria-inhibiting film that impedes bacterial growth through a chemical-free micro-texture.

The surface protection product can be used in environments where bacteria pose a health risk, including medical electronics. FLEXcon, Spencer MA, an innovator in adhesive coating and laminating, is supporting biomimetic technologies in partnership with Sharklet Technologies Inc., Aurora CO. Sharklet Technologies’ core technology, Sharklet, is inspired by the microbe-resistant properties of sharkskin and is the first no-kill, non-toxic and environmentally-friendly surface designed to inhibit bacterial growth. Sharklet Technologies selected FLEXcon because the film specialist proved to be the only manufacturer that could successfully image the patented, microscopic texture on film in large production rolls. Each Sharklet micro-feature in the Sharklet pattern must be manufactured to a specific height, width and depth in order to create a surface that bacteria find inhospitable for growth.

“FLEXcon’s application expertise, technology leadership and collaborative spirit have enabled Sharklet Technologies to innovate and bring this revolutionary product to market,” said Mark Spiecker, CEO at Sharklet. “We are appreciative to have a strong relationship with FLEXcon who not only manufactures our technology with precision, but satisfies our rigorous demands for quality and quantity.

This success provides a foundation for future Sharklet-patterned products which are intended to revolutionize the way humans and microbes co-exist.”

Sharklet Technologies’ film-based surface protection products can be applied to germ-prone surfaces to reduce the presence of bacteria. These films can be converted into adhesive-backed “skins” for application to high-touch, bacteria-prone areas such as hospital surfaces, public restrooms, childcare facilities, commercial venues, and laboratories. The film may also be manufactured into the top layer of workspace mats to create immediate and moveable surface protection.

A NEW WORLD of TREATMENT

ment clinical trial is investigating whether an implanted device can help control high blood pressure by stimulating pressure sensors called baroreceptors located on the carotid artery and in the carotid sinus. These sensors measure and report blood pressure to the brain, where it is compared to the needs of the body.

Another example is investigations on a device that stimulates the vagus nerve to control obesity; researchers testing the device have seen a dramatic drop in hypertension as an unexpected benefit of the therapy.

continued from page 16

hypertension and diabetes. Examples of devices focused on these conditions (either available now or under investigation) are provided below.

Chronic back pain

IPG devices deliver mild electrical pulses to the spinal cord, which interrupt or mask the transmission of pain signals to the brain. In this application, the IPG is implanted in the back, in close proximity to the nerve that doctors are trying to block.

Hypertension (high blood pressure)

Most patients with high blood pressure control the condition by using a regimen of anti-hypertensive drugs.

However many studies have reported a persistence of refractive hypertension (elevated blood pressure despite using

at least two anti-hypertensive drugs) in as many as 18 percent of the patient population. The IPG devices are being developed to provide a new and improved therapy for treating hypertension which is not only safe and effective, but avoids undesirable side effects of drug therapy.

The system includes an IPG, sensors and leads, external electronics for calibration, programming and periodic adjustment of parameters by the attending physician.

For example, one hypertension treat-

vated in response to direct measurement of blood glucose or symptoms, or could be activated automatically for predetermined times or intervals. Alternatively, it could be automatically activated using an implanted sensor to detect the blood glucose concentrations.

Diabetes

Several devices are being used or are under development, especially as an option for patients with diabetes that has proven unresponsive to drug therapy. An IPG is implanted and used to stimulate or inhibit the patient’s vagus nerve to modulate its electrical activity to increase or decrease secretion of natural insulin by the patient’s pancreas.

The stimulator might be selectively acti-

Accurate & Real-Time Sensing for Gesture/Motion Recognition Applications

One implantable system, originally tested to control obesity and other gastrointestinal disorders, is showing some promise in controlling diabetes. The device is designed to precisely control nerve and organ function using the vagal nerves, which regulate much of the activity of the stomach and the pancreas. The device being studied delivers high frequency, low energy electrical signals through laparoscopically implanted leads to block vagal nerve transmission. The delivery of energy to the nerves is intermittent and the effects of the therapy on the nerves and end organs are intended to be reversible.

The system is designed to be precisely programmed and non-invasively adjusted to meet individual needs.

Headaches, obesity, epilepsy, depression, Parkinson’s, syncope, sleep apnea and restless leg syndrome are a few of the many other conditions for which this treatment is being investigated.

The general trend in implantable devices is miniaturization. New devices tend to be smaller, but with a greater number of leads that get more signals into and out of a single device. It is clear that improving the feedthrough and expanding its capability is central to the next generation of IPGs. Future neurostimulator applications are currently looking at 100-200 leads, which will give device manufacturers opportunities to add further treatment to an implantable system.

“We know where the IPG device is headed and we want to proactively provide improved feedthrough capabilities to help the device manufacturers meet their needs,” says MTC-Alberox’s John Antalek.

“Just look at how far we’ve come with cardiac rhythm management. Pacemakers were the size of a Blackberry just a few years ago and had only two leads. Now the typical pacemaker is about the size of a lighter and can have as many as 10 leads, some of which allow better communication to the device, monitoring of other patient information and the ability to send information directly from the device to a doctor.”

Additional leads could also build in intentional redundancy, which would reduce the device downtime and eliminate the need to remove the device if any of the leads fail.

One of the most exciting avenues of research to increase the number of leads is the development of new high density feedthroughs that could contain ten times the number of leads, while keeping the current size and spacing.

Today’s feedthroughs are constructed by assembling many different parts, stacking them into complicated arrays with braze materials and putting them in a furnace for joining. However, researchers are now developing high density feedthroughs using cutting edge advanced ceramic materials and processing technologies that use miniaturization techniques to pack many more wires together in a much tighter space. continued on page 22

ENCLOSURES Built in 2-3 days!

CUSTOMER EXPERIENCE:

SpaceX achieves major milestone towards more reliable and cost effective space access On June of 2010, SpaceX, a private space venture chosen by NASA to provide cargo resupply services to the International Space Station, successfully launched its new Falcon 9 launch vehicle into orbit. The test launch was an overwhelming success, with Falcon 9 reaching orbital velocity and achieving its intended orbit. A company representative referred to the launch as a great day for SpaceX and a promising step forward for the US space program.

This exciting event was just one more step in SpaceX’s ambitious mission to reduce the cost and increase the reliability of space access by a factor of ten. This long term team effort combines the creativity and hard work of many individuals. One of them is George Ketigian, an Avionics Engineer responsible for developing electronics that range from in-flight devices, to testing and launch control.

Much of the ground electronics that Mr. Ketigian develops are installed in rack mounted enclosures, which he would traditionally acquire on an ‘off-the-shelf’ basis, and then customize in SpaceX’s in-house CNC machining facilities. Although this approach got the job done, sourcing and modifying enclosures takes a lot of effort and focus, and sending his enclosure projects to Protocase gives Ketigian more time for other aspects of his job.

In 2008 Ketigian adopted a new approach to this part of his job. He began to work with Protocase, who specializes in building custom enclosures for engineers and designers. Protocase’s combination of advanced enclosure design tools and unique 2-3 day manufacturing process can change the way that designers work, giving easy access to fully finished professional quality metal enclosures with a fraction of the time and effort required by traditional techniques.

Ketigian now uses Protocase’s free ‘online enclosure template generator’ tool, which creates a base design for him, and then customizes it by using SpaceX’s 3D CAD system to add details such as cutouts, fasteners, and silkscreens. The designs are then sent to Protocase who builds them in 2-3 days.

By automatically generating the base enclosure design, he retains the simplicity of dealing with off-the-shelf enclosures, in that he starts with a fully functional base design without having to design the box from scratch. But he also gains the advantages of doing the modifications in CAD, and gets a fully finished custom enclosure, built to meet his needs right out of the box.

Ketigian says, “The custom built box is more expensive than buying off-theshelf enclosures, but if I account for my own time savings, we’re actually saving money. Plus I get to focus on other more important parts of my job”.

Ketigian also notes that he achieves better overall results, which is particularly important at SpaceX. The enclosures are built to his exact needs without compromise. This includes aesthetic features which he expresses through custom graphic-like cutouts and bold silkscreen graphics. “SpaceX has a special culture. We’re relaxed, Southern California style, but totally dedicated to our work. Going the extra distance to make our electronics look great is an expression of our creativity and pride in our work.”

A NEW WORLD of TREATMENT continued from page 20

Body communications

Another interesting development in the IPG arena is the development of “body communications,” in which ultrasonic devices are placed into a medical device casing and used to remotely power and communicate with other devices in the body.

“This next level of improvement has great advantages, because it could mean that no wires would have to be implanted,” noted Mark Bartrum, transducer design manager for the ElectroCeramics business of Morgan Technical Ceramics (MTC ElectroCeramics) in Bedford, OH. MTC ElectroCeramics uses its piezo ceramic components (high density PZT and single crystal piezo materials) in medical device manufacturing.

“Implanting wires in4/30/07 the body 4:54 can bePM Trust/EP&T7x10

a challenge. They may eventually fail and subsequent removal and replacement can be difficult. Also, using ultrasound, as opposed to radio frequency, means the communication stays within the body.

This means one person’s medical device is less likely to interfere with another person’s device and it could be more readily protected against interference from MRI equipment, scanners, or other large electrical devices.”

Using ultrasound to both power and interrogate remote sensors is a likely development for many implantable devices, but wiring would still be needed for neurostimulators, where leads are attached to the skull, brain, or spine.

However, in the future, the main implant might be able to communicate with other devices implanted in the body or the external programmer via ultrasound, Page 1

rather than radio frequency.

Another exciting development, the use of piezo ceramic components, is an outgrowth from the technology used in cochlear implants. The Bedford, Ohio plant has researched a custom assembly that uses piezo ceramic components to increase resolution for an annunciator that could be inserted into a main IPG and use intelligible speech to warn the user that an event is occurring.

New biocompatible materials for IPGs Most IPGs are currently made of titanium, a strong and light metal that is lustrous and corrosion-resistant. However, along with efforts to improve the basic electrical feedthroughs so more leads can be added, research and development is being conducted using ceramic injection molding (CIM) to develop a thin-walled ceramic case that could be smaller, simpler and provide more efficient communications to the device electronics.

enables production of small components with very high precision and without a secondary grinding process.

For example, MTC’s Stourport UK CIM facility is currently in the early stages of developing an implantable housing for use in migraine and cluster headache treatment that is made using Zirconia injection molding. Zirconia is the preferred material for this device because it has a high mechanical strength that allows the casing to be made with very thin walls. The ceramic casing would then be brazed and hermetically bonded to the feedthrough.

The Zirconia ceramic casing is stronger than titanium, allowing for a mechanically robust structure in a smaller sized housing. By comparison, an Alumina equivalent would be strong, but twice as thick. Both Zirconia and Alumina are transparent to radiofrequency energy, so signals could be passed through the wall for communication and possible charging.

The hope is that developing a device casing out of Zirconia would mean that no feedthrough wires would be needed to connect to an antenna. Keeping the antenna within the device improves function for the patient. The Zirconia material is also inherently insulating, so electrical wires can be placed closer together than a metal flanged feedthrough brazed into a metal housing.

Such a device would have no need for a battery, so it would not require replacement, as long as it retains its hermetic seal.

Finally, the injection molded Zirconia is a biocompatible material that complies with ISO 13356 implants for surgery.

Next steps

The market for neuromodulation is estimated at more than $2-billion, with a compound annual growth rate (CAGR) estimated at 18-22% and a seemingly never-ending supply of new applications for the basic technology. With an increasing acceptance by the Food and Drug Administration and insurance companies, preference over some drug therapies and increasing device complexity to deliver more features and tailored effect, it is clear that developing the next generation of IPGs is critical to advancing neuromodulation technology.

What is also clear is that advanced ceramics will be a major part of that quest. Morgan Technical Ceramics’ experience as a multi-national ceramic manufacturer gives them the ability to take technologies from other parts of the advanced ceramics business and use them in parts of the business where they haven’t been used before. The same robust biocompatible materials already being used to make implantable drug delivery devices may now be used to develop a feedthrough that will be used in next generation IPGs.

Test & Measurement

OPTIMIZING microwave and millimeter measurements Where should

S

Signal analysis at microwave and millimeter frequencies is an unforgiving discipline. Even the basic task of connecting the signal under test (SUT) to the first mixer in the analysis chain is a challenge, and the choice of techniques will strongly affect measured parameters such as amplitude accuracy, modulation quality and signal-to-noise ratio (SNR).

The best choice can also optimize solution cost and convenience.

Why focus on mixer location? The answer is in the structure of almost all microwave and millimeter measurements, where the first thing the signal encounters is a mixer, used to downconvert the signal to a lower frequency for analysis. Although there are usually two or three stages of downconversion, we’ll limit this discussion to the first one, generally the only one in which the signal analyst has a choice.

This article will review the main choices for initial mixing and outline the most important information on benefits and costs to optimize a solution for specific measurement needs.

What about attenuators, preamplifiers and other signal conditioners? These are certainly important, and also affect the measurements, but they are generally choices that depend on the first one: the location of that mixer. It’s a choice that some analyzer users sometimes don’t explicitly make—but in demanding measurements it can make a critical difference in optimizing solution performance, cost and convenience.

The fundamental mixer choice Most choices related to signal connection and mixing can be boiled down to three categories: internal mixing, external mixing and “no mixer.” Each of these is worth a closer look.

Internal mixing: This is the default choice, especially for microwave (as opposed to millimeter) measurements. The first mixer is inside, and very near the input connector of the analyzer, often preceded by an attenuator and sometimes a preamplifier. This is a single-box, single-connection approach that typically uses a coaxial connection. The analyzer handles all operations including downconversion, digitizing, analysis and display. For microwave and millimeter measurements, some form of harmonic mixing is used inside the analyzer, and a bandpass “preselector” filter (inside the analyzer) is tuned to the frequency of the SUT to avoid the production or display of unintended mixing products.

the first mixer be?

By Ben Zarlingo, product manager for communications test with Microwave and Communications Division of Agilent Technologies Inc.

External mixing: This method typically takes one of two forms, either standalone mixers or separate downconversion assemblies. As the name implies, the first mixer is external to the analyzer and typically does not include an attenuator, preamplifier or preselector. Instead, the analyzer supplies a local oscillator (LO) drive signal to the external mixer and receives an intermediate frequency (IF) signal from the mixer.

This IF signal is the result of mixing the SUT with harmonics of the analyzer-supplied LO signal. The external mixer is often attached directly to the SUT using a waveguide or coaxial connection. The analyzer further processes the IF signal with filtering, digitizing, analysis and display operations similar to those for internally-mixed signals. Indeed, the analyzer user may not see any other differences in operation.

No mixer: The advent of oscilloscopes with analog bandwidths that extend to microwave and millimeter frequencies has widened the solution landscape.

When paired with signal-analysis software (typically vector signal analysis or VSA software) scopes can handle traditional signal-analysis tasks such as spectrum analysis, temporal analysis and demodulation or modulation-quality analysis. With a microwave or millimeter oscilloscope the SUT is digitized directly and the sampled signal represents the entire frequency range rather than a narrower band of frequencies in the vicinity of the signal of interest. Some would argue with the characterization of this as a “no mixer” measurement because many signal measurements still involve narrowband analysis, with the VSA software performing the downconversion (mixing), filtering and data-reduction operations normally handled by analog hardware.

Why consider external mixing?

There are numerous factors to consider when assessing where to place the first mixer. Here are four important highlights: Cost: Analyzer price generally increases with frequency range and microwave or millimeter frequency coverage is typically needed only for a specific band or bands. External mixing can allow an analyzer with only RF or low microwave coverage to analyze signals at any frequency, using the appropriate external mixer.

Convenience and sensitivity: Some microwave and many millimeter signals are provided through waveguide. Waveguide has comparatively low transmission loss but connections are typically inflexible continued on page 26

External mixing, shown here with the Agilent PXA Signal Analyzer, moves the first mixing (downconversion) stage outside of the analyzer by sending an external mixer a tuned LO signal and bringing an IF signal back in.

Further signal processing is similar to internally-mixed measurements. http://ept.hotims.com/34486-17

and expensive. It is a precision plumbing operation, after all, and connection fabrication is often the domain of an external contractor. External mixing can allow the first mixer to be bolted directly to waveguide supplying the SUT, with the analyzer connections then accomplished by flexible, inexpensive, (comparatively) low-frequency, low-loss cabling.

Frequency coverage: Some frequency ranges are only covered by externally mixed solutions. Some signals cannot be readily connected to single-box solutions because of a combination of distance, physical configuration and loss in transmission.

Performance: Direct connection of the mixer to the SUT can improve the noise figure of the measurement system, improving both SNR and accuracy.

Phase noise performance may also be improved, due to higher LO output frequencies from modern analyzers and the resulting lower harmonic numbers used by the external mixers. In some cases, externally-mixed measurements can have significantly lower phase noise than onebox solutions.

Smarter mixers An external mixer is a relatively simple thing to connect, requiring just one or two relatively low-frequency (≤10 GHz) cables for the interface with a spectrum or signal analyzer. Accurate measurements require the analyzer to be configured for the correct output frequency (mixer harmonic number) and

Choosing the best location for the first mixer in a measurement makes it possible to optimize the most important factors in a specific application.

associated mixer conversion loss. Mixer conversion loss is accounted for through frequency response curves supplied by the mixer manufacturer and entered as amplitude correction factors in the analyzer.

These amplitude correction factors can be entered manually or uploaded from a disk or USB device.

Configuring the analyzer for a specific mixer introduces opportunities for error: in the entry of conversion loss numbers, the association of those numbers with a specific mixer, and in connection problems such as inadequate or unflat LO drive levels.

A simple digital interface between the host analyzer and an enhanced or “smarter” mixer can solve all these prob-

lems at once. For example Agilent’s new M1970V/W waveguide harmonic mixers (Figure 2) store factory-measured conversion-loss parameters internally, along with model and serial number.

These mixers also contain an LO power measurement/monitor circuit to help optimize LO drive level across their frequency range and detect any connection problems. Instruments such as the Agilent N9030A PXA signal analyzer can then automatically detect these mixers through a simple USB cable, download conversion loss information, configure themselves correctly for the specific mixer, and perform an LO drive-level alignment for optimum accuracy.

The result is enhanced performance and measurement convenience, reduced chance of errors, and the implementation of a simple “remote measurement head” that can be placed in the optimum configuration to the SUT.

Conclusion Well-considered choices about the placement of the first mixer can help overcome the unforgiving nature of signal analysis at microwave and millimeter frequencies. There are many important factors in optimizing these measurements, and this article has focused on a few essential elements that can be tuned to suit specific needs. Decisions about the location and type of the first mixer drive many other choices, and these have a major influence

on solution convenience, performance and cost. Recent developments in analyzers and mixers have widened the solution landscape, and it makes more sense than ever before to begin by asking, “Where should that first mixer be?”

Multi-channel data acquisition system is portable

newswatch

Tektronix creates new oscilloscope category First mixed domain oscilloscope combines scope & spectrum analyzer functionality Tektronix Inc., Beaverton OR, has officially launched what it’s calling the world’s first mixed domain oscilloscope (MDO) that delivers the functionality of an oscilloscope and a spectrum analyzer in a single instrument.

The MDO4000 Series captures time-correlated analog, digital and RF signals for a complete system view, helping users to quickly solve complicated design issues. More than 60% of oscilloscope users also use a spectrum analyzer to troubleshoot embedded system designs with integrated wireless functionality, requiring them to work in both the time and frequency domain. Traditionally, an engineer was either a mixed signal/digital engineer or an RF engineer. But with wireless becoming more commonplace, design engineers must often work in both domains.

“We believe that this is the most revolutionary product to hit the oscilloscope market in the last 20 years, for the first time breaking down the barrier between time and frequency domains,” says Roy Siegel, general manager, oscilloscopes at Tektronix. “It fundamentally changes what’s involved in debugging designs with RF where there is a need to correlate events in the frequency domain with the time domain phenomena that caused them. Just as the mixed signal oscilloscope (MSO) is the standard for embedded design test, we expect the MDO will become the new standard for designs that increasingly include RF capabilities.”

With the MDO4000, engineers can replace both a scope and spectrum analyzer with a single instrument. This enables the user to continue using the tool of their choice, the oscilloscope, to look at the frequency domain rather than having to find and relearn a spectrum analyzer. The device goes beyond typical spectrum analyzer functionality by allowing users to capture time-correlated analog, digital and RF signals across 4 analog, 16 digital and 1 RF channel. The RF input frequency range extends up to 6GHz and provides a capture bandwidth of ≥ 1GHz at all center frequencies, 100 times wider than typical spectrum analyzers.

The unit also allows designers to see the RF spectrum of a signal at any point in time within a long acquisition to see how the spectrum changes over time or with device state. By simply moving the unique and patent pending Spectrum Time throughout the time domain acquisition, designers can see the RF spectrum for any point in their acquisition while simultaneously seeing their analog, digital and/or decoded buses at the same point in time.

Similarly, RF time domain traces are used to show how the amplitude, frequency or phase of the RF input signal changes relative to time. This makes it easy to characterize frequency hop transitions, settling times, and RF event timing relative to other system components and activities. The RF time domain traces are shown in the same window as the analog, digital and serial/parallel bus decoded waveforms, providing instant insight into device operation.

Dash MX powerful, lightweight and compact portable data acquisition system captures high frequency data and transient signals, as well as long term trending. Product records up to 8 channels of isolated voltage inputs to an internal 320 GByte hard drive at sample rates up to 200KHz per channel. High frequency data captures can be saved directly to hard drive for review and post analysis. Includes support for IRIG time codes A, B & E. Unit is equipped with a 12" color display for intuitive touch-screen control, as well as realtime data viewing and analysis.
