his month’s Brainstorm asks what design changes must be made in order for wearables to become adopted by the general population (Brainstorm, page 24). The consensus?

Smaller, longer lasting batteries. While I don’t contest these answers, the reason that I don’t wear my Fitbit has nothing to do with its size or charging requirements – it was comfortable on

T

E d i t o r

According to a recent report by Pew Research Center, 83 percent of experts say wearable technology will have a “widespread and beneficial effect” on the public by 2025. While I don’t doubt the consensus, I don’t think this “beneficial effect” will be the ability to count how many steps we take in a given day.

Recently, I had to wear a Holter monitor, a medical device that continu-

When Wearables Actually Work my wrist, water-resistant, and since I charge my phone every night, I had no problem plugging in one more device.

My issue was that the wearble didn’t provide me with any real benefit. Although I quickly jumped on the bandwagon, as my dad and sister decided we would compete to see who could get the most steps on any given day (we are a wildly competitive family), the novelty soon wore off, and I removed my Fitbit for good.

What my Fitbit did tell me was that I really don’t walk that much some days (so is the life in a cubicle) and I really don’t sleep that soundly at night.

But I knew these behaviors already.

The wearable just made it difficult to deny. Apparently walking to the coffee machine and back doesn’t force me up and around as much as I had hoped (even though it happens regularly, all day, because of the aforementioned sleep issues and general caffeine addiction).

My other qualm: It didn’t give me any credit for going to yoga but my dad racked up his steps by simply rocking in his La-Z-Boy. Needless to say, my dad still wears his, although he did take a short hiatus from the tech in a period of frustration, as he has less patience with the device’s charging time.

ously recorded my heart's rhythms for 24 hours (don’t worry, I am quite positive any issues stem from my aforementioned coffee consumption).

However, I was able to avoid a long stay in a hospital bed because of this technology. Although the technology is not new (Norman J. Holter invented telemetric cardiac monitoring in 1949) it is an example of where wearables have an opportunity to really improve quality of life.

The device let me go along about my day as normal, but it was very uncomfortable and bulky. Simple tape was still used to secure the electrodes to my skin – apparently some instances offer no high-tech solutions.

My issues with consumer wearables persist, and I remain hesitant about the many expert reports that predict our future. Yet any time I find myself feeling doubtful about impending technology, I remember that my grandfather grew up nothing during the Great Depression, and now he can FaceTime with his grandchildren on his new iPhone. That is pretty amazing.

REPLACING THE HUMVEE After 25 years, the U.S. Army and Marine Corps are upgrading the iconic Humvee.

By Melissa Fassbender, Editor

L

ockheed Martin began its foray into the tactical wheeled vehicle market in 2004. Two years later, after purchasing HMT vehicles LTD, Lockheed Martin was awarded a contract for the Army Future Tactical Truck System Army Concept Technology Demonstration (ACTD). The JLTC program was born soon after when the U.S. Congress directed the U.S. Army and Marine Corps to replace the High Mobility Multipurpose Wheeled Vehicle (HMMWV) – the vehicle commonly known as the Humvee – which has been in use since 1985.

14

May 2015

Lockheed Martin developed its first JLTV Combat Tactical Vehicle prototype in 2007. The next year the company successfully competed for the JLTV Technology Demonstration contract, which it used to continue developing the technology.

In 2014, after successfully completing the U.S. Government’s Production Readiness Review (PRR), in which they demonstrated assembly, integration, and production capabilities, Lockheed Martin submitted their production proposal.

Joining Lockheed Martin, however, is AM General LLC (who builds the current Humvee) and Oshkosh Defense, the two other companies vying for the contract to produce the next generation vehicle.

Protecting Soldiers & Marines The Lockheed Martin JLTV Team is made up of various companies with decades of military vehicle production experience, including production partner BAE Systems, which is responsible for the JLTV’s occupant-centric protection system.

Additionally, the vehicle is equipped with an independent air bag suspension from Meritor, and a unique scalable power generation/exportable power solution from L-3 Communications. The 4.5-liter, 4-cylinder engine is provided

by Cummins, and an Allison six-speed transmission completes the drive train.

Even with this impressive lineup of partners, the design process began with a simple blank sheet of paper, as the vehicle was designed from the ground up to meet the JLTV’s specific requirements.

“Our design and prototyping efforts were extensive, as we knew we had to design in not only new technologies, but also allow for growth and expansion in the future,” explains Kathryn Hasse, Lockheed Martin JLTV program director.

From day one, sustainability was one of the key considerations in the JLTV’s design. “We realized early on that we had to design and produce a vehicle that was sustainable over decades, so we designed in modularity and expandability in every possible aspect of the vehicle,” says Hasse.

To facilitate a smooth design process, the team applied robust systems engineering and lean manufacturing techniques to the entire design and production chain. Hasse explains that the processes were even applied down to the individual component manufacturers to ensure that all of the parts could handle the rigors of a military grade vehicle. Various software tools were also used for simulation and modeling purposes prior to drawing generation. The production system for the factory layout and the production processes were also modeled.

“The challenge was to engineer a family of vehicles capable of restoring protected mobility to our soldiers and marines, but doing that in an affordable manner for our customers,” explains Hasse. While she couldn’t be too specific, as the JLTV program is still in an active competition, Hasse explains that the vehicle’s protection solution is able to provide higher levels of blast protection than has traditionally been available in a vehicle of this size and weight.

“We were able to design a combat tactical wheeled vehicle system that provides MRAP [mine-resistant ambush protected] levels of protection to soldiers and marines without compromising our mobility or weight while keeping vehicle cost affordable,” she adds.

According to Hasse, achieving this was also the biggest challenge.

Closing the Capability Gap According to the Army, while the Humvee has been a reliable vehicle for the past 25 years, there has been a growing capability gap between what the vehicles can handle and what modern day soldiers need. The most important capability is protection.

“The challenge of our JLTV design was to engineer a family of vehicles capable of restoring protected mobility to our soldiers and marines,” explains Hasse. “The Lockheed Martin team takes a holistic approach to providing the best protection possible in our new JLTV.” Providing this protection is a patented hull design that dissipates blast effects, providing MRAP-levels of protection. The vehicle also features an adjustable ride height that places occupants farther away from potential blasts, further increasing survivability. “Internally, our isolation floors, shock-absorbing seats, and restraint harnesses provide significantly higher levels of protection,” adds Hasse.

Vibration dampening also provides a much smoother ride, reducing crew fatigue and stress on the vehicle components and electronics, such as the vehicle’s NetEnabled, Information-Assured Digital Backbone, which provides secure communication. “In an age where up-tothe-second information is vital to mission success, crews riding in a Lockheed Martin Team JLTV will always be well connected,” explains Hasse. “All these elements combine

to assure our soldiers and marines are the most effective fighting force in the world.”

However, all of this technology must also be reliable, and sustainable. To date, the vehicle has undergone more than 250,000 miles of testing.

“Our commercial Cummins engine and Allison transmission have proven to be extremely durable in testing, and are easily maintained and supported with a global supply chain,” adds Hasse. “Our JLTV was also designed for chassis commonality and ease of configuration for maximum mission adaptability. Modularity is built in to our JLTV design to make both maintenance and vehicle expansion simple and painless.”

However, Hasse acknowledges that any vehicle that cannot quickly expand and adapt can become obsolete. “The JLTVs were engineered with expandability options built in with no redesign needed, making them easily reconfigurable, which provides high levels of mission flexibility.”

Showcasing this expandability is the vehicle’s integrated starter-generator with a significant growth capacity. Today it is capable of delivering 15 kW, however it can reach 75 kW for future requirements, far exceeding government expectations.

Another government expectation in the JLTC competition is that the assembly line cost is below $250,000.

“Budgets are constrained,” says Hasse, “That’s why we designed our JLTV to deliver greater fuel efficiency, greater range, and reduced operational energy consumption, which all contribute to lower total operating cost-per-mile for our vehicle, as well as reducing the logistics sustainment requirements of the Army and Marine Corps.”

With a range of more than a 300 miles, the vehicle can reach speeds of more than 70 miles per hour at tactical weight. It is also CH-47 and CH-53 helicopter-transportable.

“The JLTV is far more than just a truck,” says Hasse.

“Our design is a fully integrated combat tactical wheeled vehicle system that meets today’s requirements and was designed with the future in mind.”

The Army will award the contract to a single vendor at the end of fiscal 2015 and is expecting initial deliveries in 2018, with the full production cycle ending sometime after 2030. The production will total 49,000 JLTVs for the Army and 5,500 for the Marines. PDD

A Small Robot for Compact Spaces

By Kaylie Duffy, Associate Editor

obotic assembly is becoming the cornerstone of many factories.

From large vehicles to small electronic components, robots are assembling many of world’s most popular products. However, as manufactured goods become smaller and more intricate, robots must follow suit. Comau had this in mind when it unveiled its six-axis articulated Racer 999 robot in January.

18

May 2015

“The robotics industry is moving toward faster applications in smaller and smaller layouts,” explains Alessio Cocchi, Comau marketing manager. “The requests that come from the markets are for increasingly safer robots.”

The project was derived from the Italian company’s Racer 7-1.4 robot, saving the company months of development. The Racer 999 retains the same technology platform as its older brother, but with a reduced mechanical size that is 30 percent more rigid.

The new robot features a reach of less than one meter (999 mm) and a repeatability of approximately 0.05 mm, making it more suitable for limited space applications, such as assembly, materials handling, machine tooling, and packaging.

“We carried out a series of tests measuring the speed of our robot compared to the speed of other robots in the same product category,” says Cocchi. “On a standard cycle, and with a 10 kg payload applied on the wrist, there was no match.” The company spent about 11 months developing the robot, from the first concept to pre-series validation.

Small Benefits Comau predicts that hundreds of the Racer 999 will be sold in 2015. “From the beginning, the robot has had a great [reception],” says Cocchi. “The first installation was only a few days after the robot was unveiled.” The base of the Racer 999 was designed for maximum stability, and can be mounted on walls, ceilings, and even inclined supports.

The new robot also adopts the Racer 7-1.4’s control (C5Compact), teach pendant (TP5), engines, and spare parts. However, the market’s transition to smaller component assembly requires a robot that could perform these tasks in a compact environment.

The TP5 Teach Pendant is a control box for programming the robot’s motions. It features a user interface, simplified keyboard, and enhanced ergonomics from previous versions. Both of the robot’s control units (C5G and C5Compact) are modular systems for the drive unit and I/O. The C5G drives up to 16 axes in a multi-arm configuration, while the C5Compact drives up to 8 axes.

Designed for a 7 kg payload, the robot is capable of carrying up to 10 kg, with a limited excursion of the axis 5 for high-speed pick-and-place. “The most challenging part of the robot’s development was creating a robot that was fast and reliable at the same time,” muses Cocchi. “The robot’s stiffness and speed are the robot’s most competitive advantages.”

According to Cocchi, “The robot allows a considerable cycle time savings from 10 percent to 20 percent for a joint work cycle, and from 15 percent to 30 percent for a work cycle with Cartesian movements.” In terms of production, this means an increase in performance, efficiency, and productivity.

Although the development process was relatively quick, every new Comau robot must go through a rigorous prototyping process. The Racer 999 had to go through parts and assembly engineering, 3D printed prototypes, functional prototypes, control tuning, and various tests before pre-series validation.

Human Physiognomy The geometric shape of the robot was designed to match the physiognomy of a human muscle. However, the curves of the robot are more than just aesthetically pleasing, they are directly related to the robot’s speed with which the trajectory points are met. Additionally, the robot

can utilize the company’s E-motion software to increase fluidity.

“The trajectories generated by E-motion enable companies to make the most of the technology installed,” says Cocchi. “For example, in the start and stop phases, the jerks, or variations of acceleration, are limited because the acceleration profiles are smooth.” The design was created to emulate the muscles and nerves ready to spring into action.

“The robot accelerates constantly and is performing at tops speeds, but any movement also takes into consideration the other mechanical characteristics,” explains Cocchi. “This prevents the possibility that the excessive speed in the start phase or excessive delay in the slowdown phase will affect the accuracy or repeatability of the robot’s action at a given point in the trajectory assigned.”

Due to the fluidity, reduced dimensions, and the robot’s installed energy reduction system, the Racer 999 consumes less energy. “On the mechanical arm, we mount high efficiency servo-motors to reduce energy consumption,” says Cocchi. “And the cabinet used to control Racer 999 is the C5Compact, a version of our control units (CUs) with less installed power. Moreover, in all our CUs, the high efficiency fan cooling system works only when really needed.”

Robots of the Future Although Comau has 40 years of experience in advanced manufacturing systems, it still strives to be better, whether through energy efficiency, design, or new market needs. As manufacturing spaces become more compact and product parts become more intricate, it will become more essential than ever to have robots that can keep up with the changing face of manufacturing.

“The robots of the future will be like smartphones of today,” predicts Cocchi. “They’ll have multiple sensors, be more open, intelligent, easier, more intuitive to implement, and be able to exploit many more motion axes.” PDD

INDUSTRIAL

Trends: Manufacturing

Connecting to the Industrial Internet of Things A proactive approach for enabling intelligent manufacturing solutions.

By Tom Mariano, Executive Vice President & General Manager, Foliage

F

or the first time in its brief and storied history, the Internet has more machines and inanimate objects talking to each other than people.

Cisco, the worldâ&#x20AC;&#x2122;s largest provider of Internet equipment, estimates there are now 10 billion devices and data-gathering sensors connected online â&#x20AC;&#x201C; with that number expected to reach 50 billion over the next six years.

22

May 2015

The Internet of Things (IoT) is considered the fourth evolution of the Internet (the first three major developments being the introduction of email and websites, e-commerce platforms, and the combination of social media, video sharing, and the cloud).

The much hyped IoT describes the use of web-enabled sensors embedded in physical objects to gather, track, and analyze data in the cloud, then acting on that information.

At the consumer level, the poster child for the IoT is Googleâ&#x20AC;&#x2122;s recent $3.2 billion purchase of Nest, which makes smart thermostats and smoke detectors that can be monitored with a mobile app. IoT is extending its reach to the manufacturing floor as well. For manufacturers, the ability to remotely operate and gather data from their manufacturing machinery, communicate this information through the cloud, and achieve improvements in their operations through analysis of this data is transforming the way they do business.

The Move to Automation & Connectivity The vast majority of industrial equipment today is still standalone and manually operated. Cisco estimates that only 0.6 percent of physical objects that could be connected to IoT are currently gathering and streaming data. But inside the manufacturing world, there has been a 300 percent increase in the number of connected machines over the past five years.

The potential benefits of deploying the Industrial Internet of Things (IIoT) are significant for manufacturers. A connected and automated factory can decrease downtime, increase output and quality, all while reducing labor costs. The benefits also extend to the suppliers of capital equipment used in manufacturing who can be the enablers of the IIoT. Consider the following: • Introducing equipment data tracking, remote equipment service, and predictive failure analysis can improve product reliability and minimize downtime.

• Acting on this information in real time can boost customer return on investment (ROI) through productivity and quality gains.

• Automating the operation of equipment can result in lower customer labor costs and increased manufacturing throughput.

• Leveraging the knowledge gained from 24/7 connectivity can ultimately increase long-term market share through product performance improvements.

By remotely tracking data, capital equipment suppliers can offer more value to customers by always knowing what’s happening and why, and being able to diagnose and fix problems over the Internet instead of the more timeconsuming and costly approach of sending a repair person.

Suppliers also can use this data to improve their next-generation machines.

These benefits aren’t hypothetical. The first generation of smart factories is experiencing them now. Earlier this year, Intel reported that connecting their assembly and testing equipment for semiconductor chips to the cloud resulted in a 2X improvement of their mean time between failures (MTBF) metric – the statistical benchmark for a hardware product’s reliability.

In Amberg, Germany, Siemens’ 100,000-plus square-foot factory makes automated industrial equipment for manufacturing giants such as BASF, Bayer, Daimler, and BMW. The facility is now 75 percent automated with machinery able to retrieve and assemble components with little human supervision.

As more multinational companies migrate their manufacturing plants from China to the United States, pursuing more automated production lines to offset high labor costs is becoming the norm. In 2014, Apple invested a record $10.5 billion in robotics and automated equipment to make and test its iPhones, iPads, and other gadgets in the U.S.

Deer in the Headlights Capital equipment suppliers realize their world is dramatically changing and know that their customers are – or soon will be – demanding full connectivity and automation for many types of machines on the manufacturing floor. They see that their customers’ needs are evolving, yet it is not so

easy to shift gears. For starters, there are no universal connectivity standards for the manufacturing floor. Nearly two dozen competing software platforms assert they are the best Intelligent Manufacturing solution. Complicating matters is that legacy equipment with long lifespans employs a multitude of different connectivity protocols.

Faced with this chaotic situation, many suppliers of industrial equipment are frozen in their tracks as they ponder two unsatisfactory options: 1. Wait for a potential customer to specify their preferred automated interface as part of the purchase requirements, requiring a large engineering effort with a tight delivery timetable that would result in a one-off solution for that particular customer.

2. Pre-emptively pick a solution to standardize on and develop an interface to the IIoT based on that solution, ignoring the odds that a customer may choose a different software standard or platform.

Adopt a Proactive Approach There is a third option that capital equipment suppliers may not have considered. Suppliers can develop their own interface that is independent of the connectivity standards being used by potential customers. Some suggested elements: • Aggregate the equipment control and data collection into a separate layer of the system architecture creating an “abstraction layer.” This will enable the equipment to adapt to any communication solution/platform that a customer may deploy.

• Include a data and control port in the interface that can remotely collect data and provide remote diagnostics.

• Include an application programming interface (API) so that third-party integrators can buy your equipment and integrate it into automated work cells.

Offering up your API flips the current process on its head. It empowers manufacturers to stop guessing what customers will choose for a platform and gives them their interface specifications instead. The customer can then bring in a systems integrator to make the two systems compatible. At bare minimum, this approach gives suppliers a huge head start in creating connectivity rather than be held hostage to working with multiple systems at the whim of the customer.

The promise and potential benefits of the Industrial Internet of Things are real and accessible to all. The biggest obstacle for many equipment suppliers is likely insufficient experience and expertise on how to leverage the IIoT in new systems – and also a lack of expertise on how to retrofit legacy equipment for connectivity. Leveraging the right technology and product development partner can help manufacturers proactively prepare to meet customers’ needs and anticipate what they’ll want tomorrow.

Competition in the capital equipment market is intense, and getting a jump in IIoT connectivity is critical to keeping and increasing your market share. More machines than ever before are talking on the factory floor. As the growing demand for more intelligent systems dramatically expands the Industrial Internet of Things, you can’t afford to be left out of the conversation. PDD

THE

BRAINSTORM

In the Product Design & Development Brainstorm we talk with industry leaders to get their perspective on issues critical to the design engineering marketplace. In this issue, we ask:

How does the design and usability of wearables need to change in order for the market to see widespread consumer adoption?

Mark de Clercq, Product Marketing Group Manager, Dialog Semiconductor We’re at the start of a wearable electronics revolution that will bring new meaning to personal connectivity. We’re going to be sharing more information with friends, with medical professionals, and perhaps even with our personal fitness coaches. Some experts predict a market of 175 million wearable computing devices will be sold every year by 2018.

Wearables will integrate a growing number of sensors, including biosensors, environmental and motion sensors, and microphones. The data gathered will enable wearables to become more accurate and more context sensitive. They’ll deliver only relevant data, where and when it’s needed.

Security will be critical to ensure that only the data you want to share is shared. Much of this data may be sent to cloud infrastructures via smartphones or other wireless links, where it can be analyzed.

Some wearables will be multi-purpose access devices, automatically opening doors and logging you into systems. Others will be able to control your environment and monitor your health and fitness.

With battery lifetimes being a powerful driver of consumer preference, achieving low power consumption will be a critical focus for wearables designers. This effort needs to extend to sensors, system and communications hardware, and the software.

The Holy Grail is the wearable that monitors you continuously, a wearable you never remove. This could be made possible through wireless charging or powering the device using energy harvesting. Of course, such a wearable should be as small and light as possible too.

Integrated semiconductor devices – Systems-on-Chip (SoC) – will be at the heart of successful wearables. These ultra-low power integrated circuits feature flexible processing power, built in flash memory, circuits for sensor control, analog and digital peripherals optimized for wearable products, and an advanced power management unit. It eliminates a lot of external components from wearable product design, enabling 24

smaller form factors, lower system cost and frugal power consumption. In fact, it’s effectively a ‘Wearable-on-Chip.’

Designers just add sensors, a power source, packaging, and creativity.

Rob Parenti, Technical Marketing Engineer, Alta Devices A survey by Endeavour Partners published in 2014 of 6,223 U.S. adults over the age of 18 revealed that one in ten (623 adults) owns a modern activity tracker. However, a third of those 623 adults abandon these devices within six months and over half stop use within a year. Why did those surveyed abandon the devices? In the study, lack of habit formation was identified as one of the key behavior parameters that led users to abandon their devices. In fact, users were not forming the habit of wearing the device because of inconsistent charging centered on usage. For example, an activity tracker uses small amounts of power except during times when users perform activities. If the user performed the activity during varying times of the day or for varying durations both the charge time of day and duration would also change.

How can designers increase user habit? In two ways, the first would be to create a device that the user would never need to charge. The second would be to provide a robust charge during peak activity to increase battery life. As energy harvesting chips begin to reach their limits, experts agree that solar could provide a substantial increase in battery life to the wearables market.

Adding solar to existing wearables can significantly increase the battery life and in some instances increase the battery indefinitely. Now, the user can begin to form the habit of wearing their device consistently. Furthermore, consumers consistently rate battery life as the number one feature of portable electronic devices. By both wearing the device longer and increasing battery life, solar will provide a key link for widespread consumer adoption of wearables.

Paul Karazuba, Director of Marketing & Media, QuickLogic Corporation In order for wearables to become mainstream, OEMs need to determine a way to make them invisibly ubiquitous while providing value and feedback that cannot be had from smartphones.

Wearables generally take the form of wrist-worn devices. This allows them to be a much better gauge of the user’s activity and health/wellness levels versus smartphones, as a smartphone’s carry location changes by the user (some users carry their smartphones in their pants pocket, others in a pocketbook, and others are only carried when needed). This provides wearables a unique ability to give real-time bio-feedback that cannot be done with smartphones.

If a wearable could provide feedback like “your pulse is suddenly elevated – are you OK?” or “you have been sitting for some time – perhaps you should take a walk?” consumers could perceive a value that can’t be delivered by their smartphone.

However, no matter how valuable the feedback, unless a wearable is something that can be invisibly ubiquitous (you don’t notice it, but it’s always there), they may never become mainstream.

Consumers are accustomed to wrist watches lasting two years or more with a single battery. Today’s wearable device may last less than a day with even basic use – this is likely a huge barrier to mainstream acceptance. Furthermore, consumers will continue to demand advanced features on each successive generation of wearables, increasing the power burden on already over-taxed batteries.

Wearables could be designed with much larger and

Are you a thought leader in your industry?

To participate in the next Brainstorm, email Melissa.Fassbender@advantagemedia.com heavier batteries, but would consumers be willing to sacrifice sleek designs for something more bulky and costly, but with a week’s worth of battery life? Most of us have a hard enough time remembering to charge our phones – and how many times have we been caught with a dying battery on our phone, desperately searching for a charger or wall socket? Consumers are not likely to accept this from another device – especially if it offers no advantages over their smartphones.

Without a clear application differentiator from smartphones (for instance, coaching), and without greatly improved battery life (perhaps through alternative processing architectures), wearables may never achieve widespread consumer adoption.

Mike Salas, VP Marketing, Ambiq Micro Rather than get overly technical, let’s address this question by taking a cue from the likes of Donna Karan and Giorgio Armani. In these classical wearables, it is the aesthetics, form, and function that help drive them into the mainstream. Put another way, they must look great, feel great, and provide a sense of value to the consumer.

To look great, one must be able to design a solution that the mainstream will find appealing. The problem with today’s wearable solutions is that it is typically the size of the battery that drives the form factor, when what is actually needed is to have the aesthetics drive the solution. Unfortunately, this will not be possible until we are able to dramatically reduce the size of (or even eliminate) the battery.

Similarly, to have a wearable feel great requires making it virtually invisible to the end user. Put another way, I want to wear shirts that fit comfortably on my body – why would I want a wearable that interferes with my comfort level? Unfortunately, making the wearable invisible also requires the batteries to either be incredibly small or not there at all.

Finally, to make a wearable valuable means providing users with a range of information that they find interesting or necessary. To do this requires not only the utilization of a larger array of sensors, but also that the sensors are on all the time in order to provide accurate and relevant information. Again, the requirement to keep sensors always on – much less adding even greater varieties of sensors – drives up the power budget which only compounds the battery problem.

In summary, power consumption is the key to unlocking the door. By solving this problem, it will be possible to truly unleash the potential of wearables.

Concerns of Military Computer System Configurations

By David “Avi” Shefet, President, Daisy Data Displays

There is zero tolerance for failure in the battlefield. Developing a rugged computer that lasts involves a defined process of identifying the need, designing the system, and specifying the equipment.

1. Space Allocation

The system’s footprint is as large of a consideration as its ability to operate reliably in its intended environment.

Minimizing the size of the hardware is important, but sometimes this desire is taken too far. A small form factor is desirable, but it isn’t always practical.

First: Stop thinking ultra-thin Consumer market computers are not the same as ruggedized computers, and while engineers know this, it’s desirable to specify a ruggedized computer that is super thin even when then installation footprint will not support it.

Specifiers must change this mindset and stop creating configurations that include ultra-thin computers or displays like those available on the commercial market or in embedded solutions.

Now: Start thinking custom — and collaboratively Consult the manufacturer at the beginning of the design process, not at the end when it’s time to request a quote. By consulting the manufacturer you will ensure smooth integration of ruggedized computer into your system and avoid issues related to inadequate space allocation.

2. Life Cycle What’s standard in rugged system development is to consider the lifecycle of the entire system. Three years or better is the norm, but to avoid in-field failures related to product and component life cycle, engineers should look at all parts instead of just the sum of the parts.

Not all components are considered mainstream and can be difficult to replace in the result of a failure, or may not be able to be replaced at all. If the latter issue arises, the cost is significant. Typically a complete replacement of not just the components but the entire system itself is required.

To avoid this, ask questions at the beginning of the specification process: • What is the MTBF (Mean Time Between Failure) of the entire system? What is the time measurement between the replacement of a failing part and the next failure?

• Which component is the limiting factor of the MTBF? Example: a fanless system with low power i7 processes will significantly increase the MTBF. • Have all of the individual components within my system been tested to and validated at the same level of testing and 26

standards as the ruggedized computer itself? Are all components designed to withstand the range of environmental requirements that my application demands?

• What is the life cycle for all components?

• What is the replacement or service plan associated with the computer?

3. Compatibility

Operating System Compatibility – While many government agencies and military branches choose Linux as their primary Operating System (OS) there is no acrossthe-board standard. With this lack of standardization and the many different versions of OS (using Linux’s Ubuntu vs. Debian as an example), system engineers cannot assume that the chipset will be compatible with the OS. To avoid compatibility problems, it is best to test the OS using the CPU card to make sure the system operates without problems.

EMI/RFI Compatibility – Ensuring EMI/RFI compliance for a system is critical. Electromagnetic interference (EMI) and radio-frequency interference (RFI) are among the most dangerous environmental conditions that can impact the performance of electrical equipment. However, certain components, such as power supplies and touch screens do not always meet EMI/RFI compliance for all military standards.

4. Restricted Materials Certain dangerous substances commonly used in electronic equipment in consumer applications are restricted in military equipment.

Mercury, often found in older generation LCD panels with backlight using CCFL (Cold Cathode Fluorescent Lamp), is one example. In spite of the fact that LED backlights are rising in prominence due to significant advantages over CCFL, parts containing CCFL — and therefore mercury — are still available. Systems engineers should be aware of the amount of restricted material that may exist within a computer system, particularly when using COTS.

5. Longevity & Serviceability Serviceability may be an afterthought during the initial specification process. But rising technology costs make the longevity of a solution more important than ever. To create a system that lasts 10 or even 20+ years, customization and vendor capabilities are key. PDD
