  6. 6. 6 EditorialViewpoint I enjoy hearing from you so please contact me at and your letter could be published in an upcoming issue. @ Every year, another federal budget comes out, sending various sectors into a flurry of cheers for increased spending and dire warnings of the consequences funding cuts will bring about. There may be much to argue about in the budget unveiled in March, but it’s hard to dispute that innovation isn’t high on its list of objectives. In total, it allocates almost $1.6 billion in innovation spending. Specifically, the budget is interested in fostering the broader sense of the word ratherthanfocusingonthenarrower“invention”definition.Inotherwords,itplaces greater emphasis on the “D” rather than the “R” in Research and Development. Thrown into the mix is the often unstated “C” for Commercialization. While it can be argued that Canadians are every bit as creative as their counterparts in other industrialized countries, we often get poor marks for successfully bringing those creations to market. Since the 1980s, the Conference Board of Canada has given Canada a “D” grade in innovation. That’s not due as much to a lack of patent filings or ground-breaking research, but to the comparatively little profit derived from either. According to the Global Innovation Index for 2011, Canada ranked eighth in innovation inputs and tenth in outputs but 54th in terms of innovation efficiency. To engineer this shift towards measurable results, the budget closely follows recommendations put forward in the Expert Panel Report, Innovation Canada: A Call to Action. First and foremost, the report advocated restructuring the Scientific Research and Education Development (SR&ED) tax credit program. The most significant change is that, starting in 2014, capital expenditures will no longer be eligible.TheintentbehindthepolicychangesistotakecomplexityoutoftheSR&ED application process and shift compensation toward SME’s labour-related costs. While the budget squeezes SR&ED, new funding is being pumped into more direct forms of support, again, in line with the Expert Panel Report. For example, the budget proposes doubling contributions made to the Industrial Research Assistance Program (IRAP), an initiative administered by the National Research Council to fund innovation within SMEs. In addition, the Canada Foundation for Innovation will receive $100 million annually,fornextfiveyears,tosupporttheprivatesectorthoughresearchconducted in Canadian Universities. And, to address the dearth of Canadian VC money, the budgetallocatesanextra$100milliontotheBusinessDevelopmentBank’sventure capital activities as well as $400 million to create large-scale venture capital funds. The only panel major recommendation missing from the budget was the forma- tion of a proposed Industrial Research and Innovation Council, an arm’s-length funding and delivery agency with focus on supporting business innovation. While not formally addressed, the government hasn’t rejected the idea for the future. It’s hard to anticipate what affect all this budgetary effort will ultimately have on Canadian innovation. Socially engineering success is a tricky business; govern- ment funding and economic incentives have a tendency to bounce in unanticipated directions. But whatever your political leanings, the government is at least making an honest effort to foster innovation. Like any government initiative, it will depend on how the recipients choose to use the money allocated.

Up Front Canadian Satellite Design Challenge heats up Following a critical design review held at the CSA’s David Florida Lab in Ottawa this past March, the Canadian Satellite Design Challenge (CSDC) has come down to three leading Canadian University teams. Theprimaryobjectiveofthechallengeisforuniversitystudentstodesign and manufacture an operational “cubesat” satellite, predominantly using off-the-shelf components. Of the 12 universities competing, teams from Concordia Univer- sity, University of Manitoba and University of Saskatchewan have taken the top three positions so far. Concordia University’s ConSat-1, designed by a 30-student team, is tasked with studying the South Atlantic Anomaly of the Van Allen radiation belt, to discover how it works and affects space weather. University of Manitoba’s T-Sat cube satellite carries two scientific payloads. The primary payload will study a colony of small organisms calledtardigradesandmonitortheirbehaviorwhenexposedtotheharsh space environment. The second remote sensing payload is designed to learn more about the Sun through spectroscopy. University of Saskatchewan Space Design Team’s (USST) nano- satellite is intended to measure and map plasma densities in the Earth’s ionosphere to help improve the accuracy of multi-million dollar GPS satellites. Presently, the satellites are undergoing full space environmental and launch qualification testing. When the contest wraps in October, one or more winning teams will be chosen to have their satellite launched into outer space where they will conduct its experiment at 26,280 kilometres per hour, approxi- mately 700 kilome- tres above the Earth.

NKK Switches names new president NKK Switches has appointed Michael Wada as president of NKK Switches, succeeding Kiyoko Toyama. Wada has been with NKK since 2006, previously serving as vice president of business development. Up Front Canadian bike maker leverages CFD analysis for latest racing model Canadian high-end bicycle company, Cervélo—known for the distinctive airfoil shape of its bikes’ down pipe—teamed up with, Intel, R Systems and engineering software company, CD-adapco, to test the design of its S5 racing bike before its release. As a result, the company says the S5 doubles the aerodynamic advantage its S3 model had over traditional road bicycles. Anyone who has ridden a bicycle on a windy day knows aero- dynamics play a huge role in cycling. Drag makes up 80-90 percent of the resistance experienced by an average rider on a flat road— 80 percent of this drag is due to the rider, with the remaining 20 percent down to the bicycle itself. In the design of the S5, Cervélo ran simulations using the STAR-CCM+ Power-on-Demand licensing scheme on R Systems HPC resources powered by multi-core Intel processors. STAR- CCM+ Power-on-Demand allows users to run STAR-CCM+ simulations using an on-demand cloud computing service. Based on extensive wind tunnel testing and Computational Fluid Dynam- ics (CFD) simulation, Cervélo says the S5 is the most advanced aerodynamic road bicycle it has yet developed. EADS, Creaform form partnership EADS and Creaform have entered into a technological partnership agreement covering 3D optical measurement for aerospace and defence applications. This 5-year agreement provides for the development of innovative applications in the field of optical 3D measurement for non-destructive testing (NDT), test monitoring and form and surface measurement, applied to aeronautics, space and defence. “EADS has successfully implemented Creaform’s 3D scan- ning and optical measurement technologies since 2008. The developments planned will enable EADS to reduce its develop- ment time cycle, create synergies and reduce the time-to- market of its new products,” said Yann Barbaux, Head of EADS Innovation Works. Comprising Airbus, Astrium, Cassidian and Eurocopter, EADS employs more than 1600 people in Canada through EADS Canada, Eurocopter Canada, Composites Atlantic, Cassidian Communications, Aerolia and Vector Aerospace.

  12. 12. 12 Canadian automotive RD receives funding boost Six new projects—supported by Automotive Partnership Canada initiative—were announced at the University of Windsor in March. Intended to advance RD in Canada’s automotive industry, these university-industry partnerships will receive approximately $34 million from Automotive Partnership Canada and other industry partners, including Natural Sciences and Engineering Research Council of Canada (NSERC), Canada Foundation for Innovation (CFI) and National Research Council Canada (NRC). The projects include a million- dollar investment to assist in the devel- opment of manufacturing processes to produce lighter-weight car parts, headed by Daniel Green, a UWindsor mechanical automotive and materials engineering professor. In addition, Dalhousie University received a total of $6.4 million to develop a low-cost method of producing titanium parts for automotive applications and another project to identify cell chemistries optimize battery life. Other awards include $3.7 million to the University of Waterloo to examine multi-material automotive structures; $5.5 million to Simon Fraser University to develop polymer electrolyte membrane fuel cells with lower platinum require- ments; and $2.3 million to McMaster University to identify improvements to lithium batteries. Announced by the Government of Canada in April 2009, Automotive Part- nership Canada is a five-year, $145-million initiative that supports collaborative RD and pushes the Canadian automotive industry to greater levels of innovation. COM DEV one of the best employers for new Canadians COM DEV International Ltd., a leading manufacturer of space hardware subsys- tems, announced that it has been named one of the “Best Employers for New Canadians.” This designation, awarded by the editors of Canada’s Top 100 Employers, recognizes employers that offer programs to assist recent immi- grants in making the transition to a new workplace and a new life in Canada.

  14. 14. March/April | 2012 14 If a CAD user conference is any indication, the healthy attendance at SolidWorks World 2012 suggests that the economic rebound is taking hold in North America. Nearly 5,650 registered attendees descended on San Diego Conven- tion Center this past February. That’s significantly larger than the approximately 4,300 of the year previous. To kick off the conference, CEO Bertrand Sicot’s remarks during the first general session were somewhat overshadowed by the small, child-like robot—called the NAO—that intro- duced him. Designed in SolidWorks, NAO robot is the brain- child of Paris-based Aldebaran Robotics and is intended to, among other things, help autistic children learn. Other highlights of the show included presentations by Mike Rowe from Discovery’s Dirty Jobs; NEPTUNE Canada, the world’s first underwater observatory network; and a sit- down interview keynote address between Sicot and the father of the Apple iPod, Tony Fadell. While these presentations were entertaining and informa- tive, SolidWorks World this year lacked the buzz of prior years. In the history of the event, Day 3 is typically the big reveal when execs show off what’s coming in the next release. Typically, attendees sit at the edges of their seats, eager to hear how their favorite design software will become that much more powerful. The 2012 event lacked that kind of excitement. There was simply a lack of cool new stuff. IsthisonlyaSolidWorksproblem?Notreally.It’sanindustry problem. Now that CAD tools are so robust, it’s questionable if they can be pushed much further; 3D CAD has matured to the point that most of the real cool stuff has been done. Running downthetop10bestenhancementstoexpectinthe2013release shows that there are only one or two real enhancements and a handful of nice-to-haves but one disappointment in the lot. 10Assembly visualization: You will be able to sort parts and assemblies depending on which is more graphically intensive. Combined with the feature lock capability of last year’s 2012 release, it could make working on large assemblies much easier. 9eDrawings markup import into SolidWorks drawings: Not too many people use eDrawings but for design shops that do, this is a must have. Being able to import the markups from an eDrawing into a SolidWorks drawing will likely save having to flip between multiple windows (SolidWorks and eDrawings) to get a drawing done and just do it all directly in SolidWorks. Two thumbs up! 8SectionXpert: You will be able to create sections quickly without having to make a sketch to start the command, saving a few mouse clicks. Everyone wants to save mouse clicks so this is a definite win-win. Plus, there is some added functionality to make more complex section cuts. 7Revision clouds: This is self explanatory and been in the industry since God was a child. In this case, all I have to say is that it’s about time they added this to the software. 6Bring multiple components into assembly at once: Again, this is a mouse click saver. Anything to keep carpal tunnel syndrome at bay is good in my books. 5Favorite features folder added to feature manager: Put- ting common features you use in an accessible folder in the feature manager is a good idea but to get users to put this to use might be a bit of a challenge. 4Dowel holes added to the hole wizard: Much like the revision cloud ability, this comes under “It’s about time”. 3Surface intersect: With this command, you can add and subtract material to a solid body in one step using surfaces. This is something that could be pretty awesome. CADReport As CAD software and the industry approach maturity, Solidworks pushes to generate excitement and satisfy user requests at annual conference.

  16. 16. March/April | 2012 16 2Equation entry everywhere: Being able to add equations on the fly while designing is great to have. I take notes when coming up with conceptual designs on things I need to re- address once the initial approvals are done. The most common note I take is where to add smart dimensions using formulas to be able to generate multiple iterations quickly for final design and prototyping. Now, being able to add them while in concept phase will help speed up the prototype phase. 1Backwards compatibility: This issue has been seen on the top 10 list for years and, on the surface, it seems like it’s finally being addressed. But there is a significant limitation. Backwards compatibility is limited to 2013 files being saved back to 2012, provided you have the latest service pack. In general, I think SolidWorks is going in the right direc- tion; when a recent user group meeting was polled if they could use backward compatibility, everyone raised their hands. However, when shown the current backwards compatibility functionality being proposed and asked if this would help them, no one raised their hands. Why? The fact is that users are just as shy to upgrade to the latest service pack as they are to upgrade to a new version for fear that bad things happening to their data. So if someone is using one service pack back from the last released for 2012, then this functionality will simply not work. For this group of users, this is the critical detail that makes this a bitter sweet enhancement. On the one hand, SolidWorks is adding what the users asked for. On the other, the company has limited compatibility to such an extent that it misses the mark. Hope- fully, this is just the start of SolidWorks’ backwards compatibil- ity and it will improve in future releases. SolidWorks has been taking care of bugs and stability issues for the last few years and I see a little trickle of new innovative things coming to light now that the software is more stable and less buggy. It’s hard to say what the future holds for SolidWorks. There has been talk of some great stuff coming from the company’s staff, but it’s all just rumors at this point. The company has been tight lipped, and only time will tell if they can get their mojo back with some super cool features or innovative solutions to CAD issues in the next year or two. SolidWorks is now leaving the stability and bug phase of the development cycle, so my fingers are crossed that we will see a resurgence of cool things in the future.

  18. 18. March/April | 2012 18 By Treena Hein In a world beset by fossil fuel energy woes, fusion energy is holiest of Holy Grails. A working fusion reactor would not only release large amounts of energy but, unlike nuclear fission plants, they can’t melt down. They’re also significantly “cleaner,” in that a fusion reaction only uses small amounts of an abun- dant fuel (hydrogen isotopes tritium and deuterium), which is only weakly radioactive. The problem is, no one has yet created a net gain reactor (more energy out than in), although many well-funded programs are actively pursuing it. It’s not surprising, considering the daunting challenges involved. Similar to the process that drives the Sun, a fusion reaction—meldingtwohydrogenatomstoformhelium—requires heatingthereactorfueltogalactic-scaletemperaturesandcrushed underintensepressures.Ofcourse,youalsoneedavesselcapable of producing and containing these thermonuclear conditions. Consequently, building fusion reactors will take decades, as wellasenormousexpenditures,whichiswhyenthusiasmforthis type of energy production has dampened. However, these same issues have many in the field keeping a close eye on a Canadian company,GeneralFusion,anditscomparativelylow-techapproach tofusionpower.TheBurnaby,BC-basedcompany’smechanical design sidesteps the massive costs of other leading approaches. “Fusion reactions require plasma to be heated to near 150 million˚C, and that requires a lot of energy,” says Michael Delage, General Fusion’s vice president of business development. “Where you get this energy, and how you deliver it to the fuel, has a big effect on system cost.” Reactor Design 101 To appreciate General Fusion’s concept, it’s important to under- stand how it differs from the two leading projects. ITER, a multinational collaboration based in France, is the larger and uses an approach called magnetic confinement. Using this method, a stream of super-heated tritium and deuterium gas, or plasma, is contained in a donut-shaped vacuum vessel called a tokamak. Super conducting magnets heat and compress the plasma to create the fusion reaction. The National Ignition Facility (NIF) at Lawrence Livermore National Laboratories is pursuing the other approach, inertial confinement.Itemploys192laserbeamsfocusedondeuterium- tritium pellets inside a 10-meter-diameter target chamber to convert the fuel to plasma and generate X-rays. The radiation then compresses the plasma until fusion occurs. Both methods, saysDelage,requiremassiveamountsofinputenergyanddepend on expensive, complex equipment that drive development costs into the billions and time lines out to 2050 at best. In comparison, Delage says a commercial General Fusion reactorcouldbeonlineby2020andatafractionoftheprice.The company’sapproachisahybridbetweenthetwomainmethods, called “magnetized target” fusion, and employs a comparatively lesspowerhungryreactordesign.BasedonaconceptcalledLINUS first developed by the U.S. Naval Research Laboratory in the 1970s,GeneralFusion’sreactorstartswithasphericalvesselfilled withliquidlead-lithiummetal.Theliquidmetalisthenpumped in a circle until centrifugal force forms a vortex in its center.

Asthetargetscombine,approximately200steam-drivenpistons simultaneously hammer the spherical vessel, sending a shock- wave through the molten metal. The shockwave collapses the vortex and compresses the plasma, heating it adiabatically (like a diesel engine), to produce a short burst of fusion energy. During the reaction, the hydrogen isotope atoms fuse into Helium and throw off high-energy neutrons that pass into the swirling liquid metals, transferring heat and converting some of the lithium into tritium. After the reaction ends, the metal is pumpedoutofthechamberandpassedthroughaseparatorthat removes the helium and tritium, which can be directed back to theplasmainjectorsasfuel.Meanwhile,thehotleadpassesthrough a heat exchanger that creates steam, half of which will be used to re-power the pistons and the other half to generate electricity. According to Delage, each fusion pulse will result in approx- imately 100 MJ of net electrical output. The cycle repetition rate canbevariedtocontroltheoverallpowerplantoutput;ifrepeated oncepersecond,thenetoutputwillbe100MW.Inaddition,the reactorwoulduseonlysmallamountsofdeuteriumandlithium. If fusion reactors began generating enough electricity for the entire world, Delage says, lithium reserves would last for 207 million years and deuterium for more than 67 billion years. Fusion for Less For all its promise, the quest for net gain fusion has been a time consuming and costly endeavor. The ITER reactor is projected to take 10 years and 13 billion euros to construct. That doesn’t count the 25 years and counting since the project began and the millionspouredinbycontributorssofar.Evenwhenbuilt,ITER’s superconductingmagnetsandothercomponentswouldrequire 50MWworthofinputpowertostartandmaintainthereaction. Similarly,costsforLaurenceLivermore’sNationalIgnitionFacil- ityareestimatedatupwardsof$850millionanditsreactorrequires 500 trillion watts of laser light to kick-start fusion reactions. Where General Fusion’s magnetized target method stands apart is in its relatively low-tech, low-cost mechanical means of compressing the plasma. “As an energy storage medium, com- pressedgasisordersofmagnitudelessexpensivethancapacitors,” Delage explains, “but it’s hard to release this energy quickly.” That’s the problem that ultimately scuttled LINUS, the pre- decessor of the General Fusion reactor, in the 1970s. The LINUS concept proposed impacting the liquid metal directly, which resultedinarelativelyslowvortexcollapseofupto40milliseconds, whilethemagnetizedtargetholdsitsstructureforonlyabout100 microseconds. According to Delage, General Fusion has solved this problem by impacting the containment vessel itself. “Our sphere is in fact full of holes, like a Wiffle ball,” he explains. “Each hole is plugged with an ‘anvil’ and compressed gas is used to accelerate a 100 kg ‘hammer’ piston. This accel- eration takes about 80 milliseconds. When the hammer piston impacts on the anvil piston, it moves a small amount and trans- fers the energy into the liquid metal in about 80 microseconds. That’s a timescale shorter than the lifetime of the magnetized target and an increase in power of 1000 times.” The challenge is that as the energy delivery speeds up, the requirements for symmetry of compression increases. “Every piston has to be individually servo-controlled to achieve the necessary synchronization,” Delage says. “Achieving this wasn’t possible in the 1970’s, but we are able to nurse each piston’s trajectory using a fast-response, closed-loop control system and brake, so that the timing of the impact is controlled to within microseconds. It’s the use of modern electronics—the computing power that has only come available in the last ten years—that makes our proposed system possible.” Approaching the Finish Line Presently, General Fusion is creating a prototype and key sub- systems at full scale. These include a plasma injector that cre- ates the magnetized target; individual full-scale pistons that meet requirements for impact energy and timing; and a 1-meter- diameter sphere with 14 pistons to demonstrate the symmetric collapse of a liquid metal vortex. “We’re also performing a series of experiments to demon- strate the behavior of the plasma target at peak compression CoverStory General Fusion’s reactor will employ 200 steam-powered pneumatic pistons, like this one, to create the necessary pressures to induce nuclear fusion. The largest of its kind every constructed, this plasma injector is designed to inject “smoke rings” of magnetized tritium and deuterium plasma into the fusion reactor’s core. 18-21-DES.indd 20 12-04-11 11:11 AM

March/April | 2012 21 in accordance with theoretical predictions, and developing simulation tools, matched experimental data, to be used in the design of the prototype system,” says Delage. “To date, the most challenging work has been related to the formation of the magnetized target plasma.” He says General Fusion’s plasma injector is the largest such device ever constructed. Rather than a straightforward extension of smaller systems, many issues have been overcome to achieve the necessary performance. “All our efforts have required significant innovation in mechanicaldesign,materials,electricalandpulsepowersystems, diagnostics and advancements in plasma science,” says Delage. “Italltakestime.”Thecompanyhopestohaveaprototypeoper- ating by early 2015, and a working reactor by 2020. “Thepathtoasuccessisaboutunderstandingthephysicsand the engineering and managing the outcome to produce energy safely and reliably,” notes Dr. Paul Wilson, associate professor of nuclear engineering at the University of Wisconsin-Madison. “The understanding of the physics of the mechanisms they are employing is less mature than with the two standard approaches, but they’re obviously learning more all the time,” Wilson adds. “Magnetized targets have been achieved in many experiments, but it’s a matter of determining how you can have atoms collide with enough symmetry that you get the bang and not a fizzle.” Wilsonbelievesit’spossiblethatacompany like General Fusion may beat large national and international programs to the finish line. Dr. Kevin Bowcutt, a senior technical fellow and chief scientist of hypersonics at Boeing, agrees.Heledanindependenttechnicalreview of General Fusion’s technology in 2008. “We found that their engineering challenges can be solved and they’ve been solving them since then,” Bowcutt says. “They have achieved things such as control of impact timing.” He notes that General Fusion will be holding an important physics test this summer of their plasma compression device. If all goes well, it’s likely to change the global fusion mindset. “The world has been saying that achieving fusion will cost billionsofdollarsandtakedecades,”saysBowcutt,“butGeneral Fusion’s approach, if it’s shown to work, will sidestep all that.” “I think a horse race metaphor works well,” Wilson observes. “We’reprobablygoingtoseeonehorsepullaheadandthenmaybe another catch up and maybe lead the group for a while, and so on. This will be an interesting decade.” DE At the center of a liquid metal vortex, tritium and deuterium atoms fuse, releasing a short burst of energy. CoverStory 18-21-DES.indd 21 12-04-13 2:13 PM
  22. 22. March/April | 2012 22 When choosing between position feed- back components, resolvers may just have an edge over optical encoders. By Mark McCann, B.Sc. Electrical Engineering While most motion control systems can work with either resolvers or encoders to monitor shaft position, they are not interchangeable. Many engineers are unfamiliar with resolver electronics and opt for an optical encoder as a default. As with all components, it is important to understand the basic operation of both options and keep abreast of technological advances to build the most efficient and effective systems. Both resolvers and optical encoders function as transducers bytransformingmechanicalmotionintoelectronicinformation. This information is fed back to electronic devices that control the mechanical motion, providing feedback that closes the con- trol system loop and improves system performance. A resolver is an electromechanical device with a mechan- ical design similar to a motor or a small transformer. It con- tains a rotor with one or two orthogonal primary windings and a stator with two orthogonal secondary windings. AC voltage is applied to the rotor and the voltage induced in each stator winding depends on the position of the shaft. The voltage in one stator winding is Er Cos theta, where Er is the input voltage and theta is the shaft position, while the voltage in the other stator winding is Er Sin theta. A resolver-to-digital converter (generally mounted in the equip- ment to which the resolver is connected) compares the two voltages to give a highly accurate value of theta. The biggest upside to resolvers is their ruggedness. They are MotionControl Resolvers Stage a Comeback While less common than optical encoders, resolvers provide ruggedized and reliable position feedback in “extreme” environments. resistant to electrical distur- bances and, because they have no fine-pitch gratings through which light must pass, they can tolerate dust and dirt that would stop an encoder. In contrast, an optical encoder uses a scale with a pattern of lines deposited or engraved on its surface. A light source shines on the scale, and the transmitted or reflected light passes through the grating to a photodetector. Encoders are available with both incremental and absolute outputs. An absolute encoder has as many tracks as it has output bits. An incremental encoder outputs a stream of pulses as the shaft rotates and are specified in pulses per revolution (ppr). Incremental encoders can be optical, using a scale or disk with just one or two rows, or magnetic, using several different technologies. An incremental encoder does not provide any position information at start-up, but merely keeps track of how far it has moved. The only way to determine the absolute position of an incremental encoder is to set the equipment to a known reference position and then zero the counters. Unlike a resolver, encoders are intrinsically digital, which means they can interface easily to most modern control systems. However, optical encoders have had a reputation for being fragile. The thin glass disk at the heart of most optical encod- ers could be broken by excessive shock or misaligned by strong vibration. In addition, their integrated circuits could be dam- aged by a severe electrical disturbance or they could be obscured by dirt. Over the last decade, encoders gained popularity as the glass disks were replaced with steel and plastic disks and the electronics became more integrated and durable as a result. Resolvers have also undergone a transformation in the past few years, which affects the way engineers are thinking about them. Advances in electronics manufacturing have lowered the cost of circuits and provide an increase in resolution. In fact, 21 byte resolvers are now available with more than 2 million ppr. Resolvers are also gaining exposure through their use in automotive and green energy applications that deal with environmental exposure. Compared to optical encoders, resolvers are far more durable in extreme conditions, operate under greater temperature ranges, tolerate higher vibrations and are not as easily degraded by contamination. For these reasons, resolvers excel in modern application positioning feedback for hybrid vehicle electrical mechanical components and solar panel positioning systems.

  28. 28. March/April | 2012 28 CanadianInnovator Kick Starter Canadian engineer perfects a low-cost prosthetic to help impoverished amputees. By Treena Hein Even if they are mobile and reasonably healthy, people in developing world countries face many challenges. When they lose a lower leg to a land mine or another factor, their circumstances become much more dire. What they need is a lower limb prosthetic that is durable and allows great func- tionality—but it also must cost little to make. That’s been the quest—and amazing achievement—of Jan Andrysek, assistant professor at the Institute of Biomaterial and Biomedical Engineering at the University of Toronto and researcher at the Bloorview Research Institute. “I’ve always been interested in inventing things and also fascinated by how the human body works,” he says, “so that led me to learn mechanical engineering and to use it to pro- vide bio-medical engineering solutions.” It’s been a journey of six years to create and perfect what is now known as the LC Knee—a very inexpensive, simple, tough and highly-functional lower limb prosthetic knee joint. The quest started in earnest during Andrysek’s Master’s degree on knee joints, when he investigated numerous existing types of simple lower limb prosthetics for children. “They’re all based on a handful of common mechanisms created after WWII,” Andrysek notes. “The main problem with many of them is that they do not provide stability to allow individuals to safely negotiate different terrains.” Some prosthetics are designed to provide a higher level of stability by restricting the knee from bending when the user’s weight is placed on the limb; however, this makes it difficult for the user to bend the leg as it swings forward during walking. But it’s exactly that ability of a prosthetic—to swing eas- ily—that Andrysek says provides an efficient and natural walking pattern for an amputee. He has achieved this through the creation of “Simplified Automatic Stance-Phase Lock” (SASPL) technology. “The system actually locks up the knee joint before you put weight on it, so that there’s a feeling of safety for the user,” Andrysek explains. “The unlocking occurs in response to the load conditions that occur naturally in walking. We studied this extensively and figured out that we needed to configure the limb so that the unlocking would automatically occur at the point where the weight is placed on the toe of the prosthetic, at the same time as it’s cued by the user’s hip flexion motion.” Andrysek also needed to create a mechanism that would provide a forward-swing motion that’s smooth, natural and properly-timed. “We optimized a spring and friction system that mimics the motion provided by hydraulics in more expensive prosthetics,” he says. “The faster a person walks with the LC Knee, the faster it swings forward.” But it wasn’t simply about engineering the limb to provide a natural gait—a big challenge in itself. The prosthetic had to be light, durable and cheap to make. “Plastic is great because it’s light, but the plastic parts had to be strong,” explains Andrysek. “With injection-moulding, which is the way we wanted to go because it’s so inexpensive, you can’t just make the part thicker to achieve greater strength. There are many other limitations, such as what’s possible with pulling certain shapes out of the mould.” After much tweaking and trial-and-error (and the use of a durable nylon plastic), Andrysek achieved manufacturing costs that are a stunning 90 per cent less than that required by other prosthetics with similar functionality. The final cost? Only about $100. The leg also had to be very low-maintenance, so Andrysek has incorporated self-lubricating plastic bearings and wear parts that are easily replaced after extended periods of use. Some long-term testing has been done in Central America, but Andrysek wants a broader look at how the LC Knee func- tions in different environments. A newly-awarded Grand Challenges Canada grant of $100,000 is about to help him to do just that in places like Chile, India and Tanzania. “The award is very nice,” Andrysek says, “but it’s also great to get direct feedback from the people using it or from the people who work with patients, to hear it’s allowing them to do this or that, things that they couldn’t do before. We wanted to provide a lot of function with a simple device, and it’s great to have done that.” DE Biomedical Engineer Jan Andrysek’s LC Knee is a light-weight knee joint that’s rugged, easy-to-make and works as well as standard prosthetics but at a fraction of the manufacturing cost.

  32. 32. 32 Showing off the speed, repeatability and power density of pneumatic systems in a way that captures the imaginations of weary trade show attendees can be a challenge. However, Business Development Manager Rob Clippard and a team of inventive engineers at Clippard Instrument Laboratory, Inc. have combined their interests in music and fluid power to create one attention-grabbing pneumatic application. They’re creation is the Clippard Air Guitar, a pneumatically automated guitar playing machine that incorporates 62 cyl- inders, 58 valves and an iPad as the machine controller. More than 30 cylinders along the neck of the six-string guitar depress the strings on the fret board while another cylinder mounted horizontally at the bottom of the soundboard drives a pick to strum the chords. For the melody, six cylinders across the sound hole pluck individual strings. Additionally, the “clack” of the cylinders provide percussive accompaniment. In total, Clippard says the Air Guitar took about a month and a half of nights and weekends to prototype and build. “I have a new found respect for the human hand,” he says. “The biggest challenge came when we started prototyping. “When you play guitar, the pressure you put on or take off the strings varies dramatically depending on what you want to do next,” he adds. “When controlling basic components with very high speeds and variable pressures, it’s amazing how much complexity goes into playing a single note in the way the human hand does without thinking.” To date, the Clippard Air Guitar has a repertoire of 16 songs. Similar to the rolls of punched paper of a player piano, the musical machine uses midi song files that digitally des- ignate whether a particular note is played at any given moment. The iPad functions as a time-based PLC, outputting the binary song files through a midi soundboard that interprets the on/ off of the digital signal to control the relays of the individual pneumatic cylinders. The Air Guitar made its first appearance last year at PackEx in Las Vegas but is currently on its way back from the Analytica Show in Munich, Germany. Clippard says it will most likely make its next appearance in May at the Medical Design and Manufacturing East show in Philadelphia. For those interested in re-creating Clippard’s musical machine, the company has posted a video and component list on its web site.

  34. 34. March/April | 2012 34 Choosing the most efficient control option requires full understanding of a hydraulic application. By Pat Jones, P.Eng. As with all things technical, some decisions are not neces- sarily as easy as they first appear and require a better understanding of the application. In previous articles, I have discussedthebenefitsofademand-flowsystemusingapressure- compensated pump and also with a load-sensing pump. In those cases, it was easy to see the energy/cost saving of using variable displacement pumps over fixed displacement pumps. In applications where the flow supply can be matched to the flow demand, then power is not wasted moving fluid that is not used in the circuit. Fixed displacement pumps can also be used in load- sensing type circuits. This does offer power savings over a simple circuit with just a fixed displacement pump and a relief valve where unwanted flow is forced across the relief valve (which would be set at maximum system pressure). It may also offer power savings over using a pressure compensated variable displacement pump. In a fixed displacement/load-sensing circuit, a bypass type compensator is used with the sensing line from the compen- sator connected into the circuit downstream of the flow con- trol. With this type of circuit, system pressure is determined by the load pressure felt in the sensing line, plus the spring value of the compensator (typically 200 psi to 350 psi or so). Therefore, system pressure upstream of the flow control will always be 200 psi higher than the load so the pressure difference across the flow control will always be 200 psi. When the flow control is adjusted for the desired speed, the unwanted flow is forced across the bypass compensator at load pressure plus 200 psi. This unwanted flow across the bypass compen- sator is wasted energy, but not as much as would be wasted if dumping flow across the relief valve. So how can a fixed pump circuit be more efficient than a variable pump circuit? It depends on duty cycle and the load flow/pressure demands. Consider the following comparison at a certain point in the duty cycle: System pressure setting 2,000 psi Maximum pump flow 20 USgpm Flow to circuit 15 USgpm Load pressure 500 psi In this scenario, the system efficiency of the pressure com- pensatedpumpisapproximately25percentwhilethefixedpump with load sensing achieves about 44 percent efficiency. From the graphs 1 and 2 above, you can see that, in this condition, the pressure compensated pump circuit will be much less efficient due to the control’s inability to sense the load. In this high-flow/light-load situation, the fix pump with load sensing-type circuit is much more efficient. This example points out that the nature of the control and the motion profile of the load, as well as duty cycle, must be clearly understood to choose the most efficient control option. It may be the most efficient to always specify a variable load- sensing pump for all circuits; however, if the duty cycle is intermittent usage, then a total cost case can be made for a fixed pump, load-sensing circuit. In a previous article, I mentioned that closed loop hydrau- lic circuits represent an efficient circuit option. The advantage to these drives is that—because both the direction and speed of the load are controlled with the displacement of the pump— the throttling losses of open loop hydraulic circuits are eliminated. This type of circuit offers one of the most efficient hydraulic circuits possible. In a typical closed loop circuit, there are two pumps: The main loop pump that controls the load and the charge pump that supplies make-up fluid for main loop leakage and also Maximizing Hydraulic Efficiency FluidPower: ShopTalk AD-116 34 FluidPower: Shop Graph1: Pressure Compensated Pump Graph 2: Fixed Pump with LS Control 34-37 DES.indd 34 12-04-11 11:46 AM

The charge pump is usually fixed displacement and continually forces fluid across a relief valve that is typically set from 350 – 500 psi. Thechargepumpsizewouldtypicallybe10-15percentofthe main loop pump. So the continuous wasted energy is always at least the charge pump flow across the charge pump relief. The worst-caselossiswhenthemainloopisatfullloadandthemotor and pump are at maximum leakage. This could typically repre- sent10percentofmainlooptotalflowbeingforcedthroughthe pump and motor clearances at full load pressure. Using the same flow and load pressure numbers from the example above and assuming a charge pressure of 350 psi we see that, in the worst case, the closed loop circuit efficiency will be approximately 83 percent. So, why aren’t closed loop circuits used everywhere if they offer such a distinct efficiency advantage? Considering that one main loop pump is required for each load, this is very practical on a stationary crane where there would be four main functions: Main boom, rotation, extension and winch. This makes for a very compact and efficient circuit. However, as the number of loads grows and possibly the distant between them, having a separate closed loop circuit for each load becomes less practical from a machine design point of view. One input power source, capital cost wise, is very cost effective as opposed to having multiple closed loop circuits and the necessity of multiple prime movers. Of course, the long-term energy costs need to be weighed against this. Fromanefficiencystandpoint,thereareclearstandardoptions available. It’s a matter of understanding the combined flow- pressureprofileoftheloadsandthemachinedutycycleandthen looking at capital and longer term costs to determine the best solution.Efficiencydoeshaveacost,butwecancalculatethereal cost of proper design if we understand all the variables.

So, high quality products, particularly those that protect the operator, are gaining the most in popularity. —Shane Monaghan, Product Manager, Fluid Power Division, Gates Canada Inc Canadian leaders discuss the market, globalization and grooming the next generation of fluid power professionals. By Mike McLeod DE:Formanyinthefluidpowerindustry,2011wasarebound year. How would you characterize 2012, so far? Shane Monaghan, Product Manager, Fluid Power Division, GatesCanadaInc:ForGates,2011wasanexcellentyear.Infact, Gates Canada was recognized as the largest growth region for all of Gates North America. You can attribute those high sales to forestry, oil and mining—our top three markets.

Those are the end markets we want to attack for 2012. SteveApps,SalesProductManagerforMobileMarkets,Bosch Rexroth: For us, 2011 was definitely a good year, and 2012 is looking the same if not better, although it’s a bit early to tell.

Prior to therecession,therewereagreaternumberofcompaniesineach ofthosedifferentsectors,butthedownyearstooktheirtoll,and somecompaniesdidn’tcomeback.Thosethathavearegenerally what I would consider larger OEMs—that is, companies that deal both locally and internationally. AndreasSobotta,VicePresident,ProductandMarketManage- ment, Festo Canada: We had a very strong start to 2012, more or less in all industries except automotive which was expected to be flat. Assembly and handling; food and beverage; and natural resources are all very strong. This is something that we anticipated, and we are getting stronger in these areas where we were already strong. The reason is that we aren’t just selling products; we sell solutions, and our customers appreciate this. Festo has been focused on this worldwide, so that customers will see us as a partner instead of just a supplier. Kevin O’Doherty, Regional Manager, Hydraulic Systems and Services, Wajax Industrial Components: From our perspective, 2012 is definitely going to be a more robust year than 2011, which was better than 2010. Through the first quarter, sales are up across both industrial and mobile seg- ments and we’re hopeful the trend continues. The rebound is being led by the resource businesses, whether its oil and gas in Western Canada or metals and minerals here in Ontario.

  39. 39. Steve Apps For the mobile hydraulic market, emission control is probably the biggest consideration. Meeting the Tier 4 emission standard will affect performance, costs, physical design and a number of other things. — Steve Apps, Sales Product Manager for Mobile Markets, Bosch Rexroth As well, I think a lot of companies, through the belt tighten- ing years, performed a bit less maintenance on their machin- ery in plant. Now that production is beginning to ramp back up, they do have to put those investment dollars back into their machinery. DE: At the NFPA annual conference in March, the prevailing themewasglobalization.AreyourCanadiancustomerslook- ing beyond the U.S. market? Monaghan-Gates: Absolutely. We have Canadian distributors who supply mines in North Africa, as well as agriculture equip- mentinRussia,EuropeandAsia.Forthepasttwodecades,Gates hasbeenonfivecontinents.Whatwe’vedonetohelpdistributors is develop a global product. Any OEM, across the globe, can purchase our products so they don’t have to import the product from a specific country of origin. We’ve also re-named most of our hose and fittings to include the letter “G” for global, which means that no matter where you buy it, it will be manufactured to the same specifications and standards. Apps -Bosch Rexroth: From my perspective, this has always been there. When the demand for domestic machines was higher, maybe globalization wasn’t as prevalent because cus- tomers could concentrate on their own backyard. With the change in the Canadian economy, the factors that influence production or harvesting of natural resources has dropped. As a result, to stay in business, people are looking for markets other than Canada and the U.S. One of the advantages we have is that we are able to draw on the applications and expe- 39FluidPower: Roundtable March/April | 2012 38-41 DES.indd 39 12-04-13 2:22 PM

Festo has been focused on this worldwide, so that customers see us as a partner instead of just a supplier. —Andreas Sobotta, Vice President, Product and Market Management, Festo Canada rience of companies from around the world. Also, people want to know that what we are supplying is going to be sup- ported if it is shipped, for example, to Eastern Europe. That has a certain attractiveness to local Canadian companies. Sobotta-Festo: About 75 percent of Canadian exports still go to the U.S., but I know that a lot of customers are looking to expand into new markets. For example, some of our Canadian customers are exporting into South America and some pulp and paper companies into Europe. Yet, it will take some time for some to look beyond the U.S. The difficulty is in the require- ments and the expectation in Europe. They are used to a more sophisticated level of product. For example, in Europe, they use more bus systems and smaller products with better per- formance. For a lot of U.S. companies, if something isn’t big, it can’t be good. It’s important for some of our customers to re-think their approach into new markets. O’Doherty-Wajax: Our customers are definitely looking at the export markets. For example, a lot of the mining machin- ery OEMs we work with are doing more business in South America and Africa as well as parts of Russia and Asia. So, we definitely see customers taking a much more globalized approach to their sales channels versus just Canada and the U.S., the way it was a few years ago. Wajax is very much a Canadian-based company, so we don’t sell directly into other countries, but we do support the after-market for products that we manufacture here in Canada. DE:Technicallyspeaking,whattrendsaredrivingyourcom- pany’s new product development? Monaghan-Gates: For 2012, Gates has budgeted nearly double the industry standard for product growth to create products designed for specific regions. For example, in Canada we are coming out with a low-temperature product— an arctic version of a hydraulic hose. We are also re-releasing global products with improved pressure ratings and minimum bend radius. The product capabilities gaining the most trac- tion have to do with safety, which is always a concern in the fluid power industry. For example, our Lifeguard line of sight hydraulic hose sleeves protects against catastrophic failure. If the hose were to burst or there were a pin hole, the sleeve protects the operator. Safety is more of a concern for OEMs now, and it’s a selling feature for them as well. Apps-BoschRexroth:Forthemobilehydraulicmarket,emission control is probably the biggest consideration. Meeting the Tier 4 emission standards, which come into play at the beginning of 2014,willaffectperformance,costs,physicaldesignandanum- ber of other things. That single point has played a large role in shaping, not only the components themselves, but the system concepts. The trick is to find ways to improve a machine’s operation or performance such that it’s emissions are reduced. Bosch Rexroth saw this coming because there is an internal connection between the automotive and hydraulics sectors. So, we have some access to the technologies and concepts used in the automotive industry, which was hit with these emission standards well before the off-road industry. Sobotta -Festo: The new trend coming from Europe is that products need to be more efficient. As a German company, we aretryingtoconvinceourcustomerstojumponthatbandwagon and be more productive. In terms of product, what we see is smaller, faster and more energy efficient. In terms of products that are gaining traction, customers want to have more flexibil- ity so we have a single form factor product series that allows differentsizevalvestodrivedifferentapplicationsoverdifferent distances, all in one control panel. Additionally, you have the abilitytoconnecttoanytypeofbussystem.Whetheracustomer has an Allen Bradley, Siemens or Omron system, they can take advantage of their existing software to drive our modules. O’Doherty -Wajax: We see a lot going on with electronics and with the quest for higher pressures. For example, the marriage between high-pressure hydraulics and electronic systems on mobileequipmentisbecomingmuchmoreofatrend—anything that helps with emissions and fuel consumption but increases payloads. If you fill your car each week, you know it isn’t getting any cheaper. Of course, the bigger the equipment, the more fuel they burn, so if they can get something as miniscule as a five or 10percentfuelsavings,thattranslatesintosomefairlybigdollars for these guys at the end of the year. DE: Which strategies or initiatives are you finding most suc- cessful in developing tomorrow’s fluid power professionals? Monaghan-Gates: Recruitment is definitely an issue and has been for a number of years. We combat that through the high schools and colleges. To get the fluid power name out there, it’s usually best to find a high school senior who hasn’t made 38-41 DES.indd 40 12-04-11 12:20 PM

It is really incumbent upon us to take the lead in their development such that we can hone their skills and turn them into a value player. —Kevin O’Doherty, Regional Manager, Hydraulic Systems and Services, Wajax Industrial Components up his mind yet. Specifically, Gates provides a lot of product and equipment to high schools and we give out six scholar- ship awards every year to high school seniors. We also put on training courses at colleges and offer engineering services to FIRST Robotics, where a large number of participants go on to pursue a career in engineering. Sobotta-Festo: Festo is one of the largest sponsors of Skills Canada competitions for colleges and universities. The last World Skills competition was held in Calgary, Alberta two years ago and we got a lot of interest from Alberta colleges and universities, which not only generated business for us, but they have now incorporated our equipment into their curriculum. As a result, students become familiar and ben- efit from this advanced learning technology. We also have a unique product offering for high schools that is at the begin- ning of the implementation phase, which is well underway. We just have to work on the curriculum so that high schools move toward a more automation and pneumatic focus. O’Doherty – Wajax: As an industry, I think this is one of our biggest collective challenges. There is very little talent walking out of schools ready to go these days. Most people in fluid power have to be built from within. It’s really incum- bent upon us to take the lead in their development such that we can hone their skills and turn them into a value player. A lot of companies have backed off the throttle a bit, especially through the recent recession. But as business starts to ramp back up, we definitely see the need to train, develop and build our own.
