Schaeffler, with our INA and FAG brands, has set a standard that is unrivaled throughout the industry by offering innovative products and unmatched support services that can dramatically improve the performance and reliability of pumps used in wastewater, dewatering and petrochemical applications. Here’s why this is no idle boast: Innovative Products Schaeffler’s latest generation of double-row angular contact bearings in X-life™ quality generate less friction, put less stress on lubricants and enable lower operating temperatures. Thanks to higher ball quality, improved raceway surfaces and more precise dimensional and running tolerances, the bearing’s internal friction is significantly reduced. As a result, higher speeds or longer bearing operating life can be achieved. So reliability goes up, and energy consumption goes down. Groundbreaking Technology X-life is Schaeffler’s designation for premium products from our INA and FAG brands that offer engineers completely new design perspectives. Thanks to superfinished raceway surfaces that ensure smooth, uniform running characteristics, maximum load-carrying capacity and superior rigidity, the operating life of X-life bearings is considerably longer than standard bearings under identical operating conditions. Alternatively, higher loads can now be applied while maintaining the same rating life values. Unmatched Engineering Support The industry’s most comprehensive suite of calculation software, BEARINX® is Schaeffler’s cutting-edge program for performing rolling bearing and linear guidance system calculations. One of our latest modules, BEARINXonline “Easy Friction” enables customers - free-of-charge - to calculate all of the friction forces at the discrete points of the contact surfaces inside the bearing. When it comes to bearings for your pumps, don’t just go with the flow. Go with Schaeffler. Need more details? Please contact us at ads.ind@schaeffler.com www.schaeffler.ca ©2013

Birth of an Idea

www.design-engineering.com

here’s no telling where the next big idea will come from. We expect such things from research and development mavens at the top of their respective fields in IT, engineering, medicine or what have you. Sometimes, however, they spring from the most unlikely of people based on the most seemingly unrelated spark of an idea. Take the case of 60-year-old Jorge Odón. He isn’t an obstetrician, doctor or in any way associated with the medical profession. Nor is he an engineer specializing in medical equipment. Instead, Mr. Odón is a car mechanic from Argentina. Still, his simple invention is considered by the World Health Organization (W.H.O.) as the most promising solution to a problem that threatens the lives of expectant mothers and children in developing countries and costs millions in developed countries due to delivery complications. His device assists in cases of obstructed labor, often brought on when the baby’s head is too big or the mother’s contractions cease from exhaustion. According to the W.H.O., this birth complication plays a major role in millions of stillbirths each year around the world. Even in developed countries like the U.S., the rate of C-section has risen to approximately 33 percent per year, or one in three births. A statistic like that translates to not only skyrocketing healthcare costs, but also potentially serious health problems for mothers and children. Odón says the idea came to him in his sleep, after watching a YouTube video explaining how to remove a cork pushed into a wine bottle. In the video, a portion of plastic grocery bag is placed in the inverted wine bottle, so the cork falls near the neck. The bag, blown up like a balloon, envelops the cork and allows it to be pulled easily from the bottle. Similarly, the Odón Device employs a plastic sleeve lined with a plastic bag that surrounds the baby’s head. As the bag is inflated, it grips the cranium and evenly distributes pressure as it eases delivery. Current methods of assisted childbirth employ a suction cup attached to the baby’s scalp or forceps, which can introduce significant risk, especially when used by the untrained. Although his wife and family thought his idea was crazy, Odón worked on the project in his garage using a glass jar, a fabric bag and his daughter’s doll. He spent years refining the device, but it wasn’t until he showed the idea to the chief of obstetrics at a major Buenos Aires hospital before it was taken seriously. Since then, the Odón Device has received grants from Grand Challenges Canada and the United States Agency for International Development as well as endorsement from the World Health Organization as a cheap (it will cost less than $50 to make) and easy-to-use alternative to forceps for mid-wives working the third world. So far it has been successfully tested on 30 women in Brazil but will soon enter further trials around the world. The interesting thing about Jorge Odón and his device is that, although obstructed birth has been a serious medical problem since the beginning of the human race, little progress had been made toward solving it other than refinements to past, less effective techniques. Sometimes, with an intractable design problem, it takes someone who doesn’t know any better, who is unconstrained by history or popular wisdom, to lend a fresh pair of eyes and thereby change the world.

Canadian $100 3D printer blows past crowd-funding goal

group of Canadian inventors, (operating under the company name Rinnovated Design), have blown past their modest funding goal of $50,000 with the promise of a 3D printer, called the Peachy Printer, that costs only $100. After posting the project to Kickstarter Canada, the group raised more than $650,000. According to the project’s leader, Yorkton, Saskatchewan resident Rylan Grayston, the aim of the project is to make 3D printing affordable enough for anyone. Similarly oriented hobbyist or prosummer printers, like the 3DSystems Cube or MakerBot’s ReplicaInvented by Yorkton, Saskatchewan resident, tor, typically retail for Rylan Grayston, the Peachy Printer rapid prototype $1,300 or more. machine has raised more than $650,000 on The Peachy PrintKickstarter Canada crowd-funding web site. er’s low cost largely stems from its unique lithographic process. Instead of a printer head or extruder moved on the x and y axes by motors, the Peachy Printer uses laser light reflected by two electro-magnetically controlled mirrors. The directed laser light then solidifies layer after thin layer of a photo-sensitive liquid polymer. To control the z-height of the object, the printer uses a drip system to slowly raise the level of the polymer within a fish tank-like build space; as each build layer cures, the object being printed is submerged under the rising liquid and the process repeats. By the end of the build, the final print has been suspended in a tank of the uncured polymer that acts like support material and can be reused for the next print job. Similarly unconventional is the fact that the Peachy Printer doesn’t process .stl files directly. Instead, geometry created or imported into open-source 3D modeler, Blender, is output through the audio-out port of a computer sound card and transfers to the Peachy Printer via a standard stereo jack. By way of a Blender plug-in, geometry is converted to digital waveforms that control the Peachy Printer’s mirrors and thereby dictate where the laser will solidify the polymer for any given layer. At present, the Peachy Printer is a rough but functional prototype but contributors who pledged $100 or more will receive a Peachy Printer kit for assembly. The developers’ hope to use the funding to refine the printer’s z-level drip system to attain higher resolutions and further polish the final product. www.peachyprinter.com www.design-engineering.com

The National Research Council of Canada (NRC) announced that it will partner with Unmanned Aerial Vehicle (UAV) maker, Brican Flight Systems. As part of the agreement, the NRC has chosen the Brampton-based firm’s TD100 fixed wing UAV as its ‘platform of choice’ for its Civilian Unmanned Aircraft Systems program (CivUAS), an initiative to accelerate the development and improve the adoption of UAVs for civilian use over Canadian domestic airspace. According to the company, Brican will work with NRC’s aerospace engineers over the next five years to solve specific UAV technical issues, such as flight safety, sense-and-avoid technologies, anti-icing, flight operation interfaces and data collection. Presently, the TD100 is going through a commercialisation program to demonstrate the safety and value of remotely piloted aircraft systems for use in hazardous and remote environments. The company says commercial UAVs represent a cost-effective way to perform certain tasks such as inspecting remote stretches of power transmission lines, pipelines and other infrastructure that traverse vast areas of open territory. With a max payload capacity of 9kg (20 lbs.), the TD100 can be equipped with HD and infra-red video and mega-pixel still frame cameras to collect data during automated patrols over remote area. www.bricanflightsystems.com

3D printing materials market to exceed $600m by 2025 A report released by industry research firm IDTechEx says the 3D printing materials market alone will be worth in excess of US$600 million by 2025. According to the report (3D Printing Materials 2014-2025: Status, Opportunities, Market Forecasts), the market for photopolymers will retain the largest single segment of the market through to 2025. Other materials are projected to gain market share as the technology matures from purely prototyping/tooling applications to final product manufacture. The report states that metal powders will see the highest growth, although production will remain relatively low. This,

in combination with high raw material and processing prices, will cause the price of metal build material to decline slower than other materials. While most media attention focuses on additive manufacturing machines themselves, the report points out that the materials market for 3D printing is the most contentious issue in the industry presently. Mirroring the 2D printing industry’s “razor-razorblade” business strategy, 3D printer manufacturers are increasingly employing lock-in strategies on the build materials using key-coding and RFID tagging of material cartridges. Perceived by end-users as anti-competitive, the activity is effectively enabling monopoly pricing, while hindering development of new 3D printing materials and maintaining high barriers of entry for 3rd party suppliers. Those who do enter the market are unable to get the economies of scale required to accelerate both materials development and progress towards a competitive market. The report concludes that downward pressure on materials prices, in the short to mid-term, will be driven mainly by new 3D printer manufacturers that allow customers to source materials from 3rd-party suppliers. In addition, downward pressure will come from large end-users wielding buying power. www.idtechex.com

What’s New in

SOLIDWORKS Dassault Systemes’ latest version boosts the popular 3D modeling software’s drafting, sketching, sheet metal and assembly handling capabilities. By Ralph Grabowski

assault Systemes is riding on a high these days. With 2.1 million licenses of SolidWorks out there and $2.8 billion (est. for 2013) in revenues, it is by far the largest CAD vendor on the planet. Admittedly, the majority of those 2.1 million licenses are used by educational institutions only for training, but that’s true of any MCAD program. To put the numbers in perspective, November/December | 2013

Siemens PLM last summer announced that it has sold “over” 550,000 licenses of Solid Edge, education and commercial combined. Several years ago, Autodesk stopped announcing Inventor sales, but analysts guess its number is perhaps half that of SolidWorks. Dassault’s numbers are remarkable, considering the world economy is not robust and that, a few years ago, SolidWorks itself was in a slump, feature-wise. Users back then complained that the www.design-engineering.com

programmers (who were under new management) lost sight of what designers needed: Better tools for getting work done more quickly. Hyped functions like 2010’s SustainabilityXpress (for determining how “green” a design is) and 2011’s n!fuse (social collaboration) weren’t popular. So, what brought about the turnaround? Dassault realized they needed to go back to targeting the real customer. SolidWorks was not deployed by large corporations so much as by small shops. Small shops make things locally, and so it was irrelevant to them how green things shipped from China were; no need to collaborate remotely, either, when the entire staff of two is in a single room. www.design-engineering.com

14-17-DES.indd 15

What’s New The last couple of releases of SolidWorks were catch-ups, where programmers worked to add useful functions that helped designers — rather than pleasing management and accounting types. SolidWorks 2014 repeats the formula, helping its sales figures rocket beyond the competition. Let’s take a look at some of the functions Dassault added to the new software. 2D Design and Drafting: There is an emphasis on 3D in many areas of technology, yet 2D is where the work gets done in the form of flat drawings used on the shop floor. SolidWorks 2014 makes ordinate dimensions available to measure angles in drawings, and these can be placed automatically. By holding down the Shift key, two points can be dimensioned on a single arc. The Dimension PropertyManager is used to change the line styles of leaders and dimension and extension lines. The Hole Wizard now generates slots with or without counterbores and countersinks. Long tables are split automatically to fit the space available. Patterns (arrays) in curves and sketches (no longer just parts and features) now generate patterns for assemblies, such as for making holes and linear types of repeating elements. Also, soft snaps work at 15-degree intervals. A cool new function locates “virtual sharps,” which is where SolidWorks finds the virtual intersection of two geometric features that don’t physically intersect. This makes it easier to dimension offsets. Balloons and labels get small boosts in lots of areas. For instance, leaders can be fi xed to balloons, and we can specify the distance between the balloon border and its text. Any balloon can be reattached to any component, and balloon arrows can be moved independently of drawing views. In sketches, we can now use driving dimensions to specify a path length for closed loops of entities, such as for all the parts that make up a bicycle chain. Also interesting is the new Replace Sketch Entities function that replaces existing entities with new ones; SolidWorks 2014 then updates all references.

In addition, relations and dimensions can be applied to control vertices. Assemblies: SolidWorks 2014 makes it easier to work with parts in assemblies. Hold down the Ctrl key and, when we click entities we want to mate, a new toolbar appears that lists only the mates appropriate for the geometry. A new type of mate joins curved objects by their tangent points, and to linear objects like lines and sketches. Components can be mirrored in assemblies through bounding boxes, instead of by the center of mass. Subassemblies can be toggled between rigid and flexible states just by clicking a new button on the Assembly toolbar. When an assembly is exploded, we can now specify that parts rotate, with or without linear movement. Sheet Metal: Sheet metal design seems simple, yet functions are added with every release to every MCAD program. This time in SolidWorks 2014, there are gussets for stiffening sheet metal boxes, more control over how corners are generated, and lofted bends that takes into account the limitations of press brakes. When we sweep a linear sketch entity along a circular path to create cylindrical and conical sheet metal shapes, Solid-

Electrical: A few years ago, MCAD vendors realized that electrical design is a rational way to expand their systems, because all electronics have to be housed in something designed with MCAD. SolidWorks 2014 includes dozens of new ECAD functions, such as inserting passive symbols, resolving equipotential conflicts manually, and many more functions for generating and formatting reports.

The Future of SolidWorks Ever since 2010, when then-SolidWorks CEO Jeff Ray announced the software was being rewritten for the cloud, users and pundits worried about the future of SolidWorks on the desktop. Since that ill-fated announcement, Dassault was forced to state repeatedly, “The desktop version is not going away.” Instead, a parallel cloud-based version is being worked on, albeit slowly. Dassault is basing the cloud version of SolidWorks on Enovia V6, the company’s PLM database that undergirds all of its V6 software. Every bit of data, including CAD data, is stored in this database; there is no longer a discrete “CAD fi le,” such as .sldprt — only the ability to export CAD data in formats like 3DXML. Dassault is combining SolidWorks, Catia, Enovia and all its other software in something it calls the “3DExperience Platform.” As I write this, the 3DExperience platform for the cloud is planned for release in January 2014. Explained Dassault CEO Bernard Charles, “New products of the SolidWorks family will take advantage of the 3DExperience platform online.” After a series of missteps four years ago, Dassault Systemes recovered successfully by adding to SolidWorks functions desired by end-users, while working separately on a cloud-based version that will please large corporations.

Takes FLIGHT Design Engineering Expo welcomes a record number of attendees and exhibitors.

he Design Engineering Expo hit a new high this year as a record number of Canadian engineers, machine builders and OEMs descended on the tabletop show held September 30 at the Mississauga Convention Centre. In total, show attendance grew by nearly 35 percent over its inaugural year, signalling to the show’s manager, Alan Macpherson, that DEX is striking a chord with Canada’s engineering community. “DEX Mississauga exceeded our expectations and we very much look forward to expanding the show to other manufacturing centers across Canada over the next two to three years,” Macpherson said. “We’re adding two additional shows in 2014, Coquitlam and Calgary, and plans are in the works for another two shows in 2015.” As with last year’s shows, located in Mississauga and Coquitlam B.C., the one-day tabletop trade expo showcased some of the latest industrial products and design tools. Overall, nearly 79 percent of exhibitors described DEX 2013 as good to excellent. In addition, 85 percent of those surveyed rated attendees as well qualified. Of those in attendance, 90 percent said they plan to attend DEX 2014 in Mississauga next year. In part, buzz at this year’s show was generated by the expanded Design Pavilion, a showcase of Canadian engineering talent and their innovative projects. First and foremost among those on display were keynote speakers, Dr. Todd Reichert and Cameron Robertson of Toronto-based AeroVelo. The aerospace engineering duo were the driving force behind the Snowbird ornithopter, the world first flapping wing aircraft to sustain flight, and the human-powered helicopter, Atlas, that won the Sikorsky Prize, a feat many in the aerospace community claimed was mathematically impossible. “Math doesn’t lie so if it’s telling you that something is impossible, then you have to look at the underlying assumptions,” Reichert said. “People say you have to think outside the box, but at the same time you have to fully understand what the box is, learn from the experience of others and unconstrain the problem from the outset.” For their next impossible task, the pair look to break the human-powered land speed record of 133 kph in an aerodynamically-refined “speed bike” called Bluenose.

in a fibreglass shell, the recombinant bike utilizes a video camera in its tail fin and a display in the cockpit in place of a traditional windshield. Reichert, who pilots all of AreoVelo’s human-powered vehicles, says the new design allows for a smoother and more aerodynamically efficient shape. In addition to AeroVelo, Jeffrey Azzolin and his spring-loaded Bladetech hockey skates drew a crowd at the event. Azzolin’s innovative approach to the classic ice skate not only reduces the risk of stress-related injuries but helps skaters jump off the line and speed down the ice faster. University of Waterloo brought its entry to General Motors’ EcoCar 2 competition, a modified hybrid electric Chevy Malibu with an all-electric range of 60 km plus a 2.4L engine to provide power and extend vehicle range. For racing fans, the University of Toronto’s FSAE Racing Team showed off its student designed and built formula-style racecar. The DEX Expo also showed off the robotic building talents of Team 4814 of Western Engineering’s FIRST robotics club (WE FIRST) who demonstrated their Frisbee-throwing robot that won multiple awards at this year’s FIRST Robotics World Championship. Similarly, Queen’s University’s Space Engineering Team (QSET) displayed their student-designed and built lunar rover that will be entered in the University Rover Competition.

Vaporizing Regulators A vaporizing regulator is a pressure-reducing regulator used either to prevent condensation or to induce vaporization. The reason for preventing condensation is to forestall rapid pressure drop that could result in the JouleThompson effect and cause a regulator to freeze up. The Joule-Thomson effect is caused by a gas losing heat as it undergoes a complete or partial condensation. A vaporizing regulator applies heat via a steam or electric heating element at the point of the pressure drop, preventing the condensation from occurring. In other cases, such as are typical for gas chromatograph applications, it may be desirable for a liquid to be vaporized. In this instance, the vaporizing regulator applies heat to vaporize the liquid to a gas. www.design-engineering.com

One- or Two-Stage Regulators The manner in which a regulator adjusts to variations in the high pressure supply is known as supply pressure effect (SPE). In general, one-stage pressurereducing regulators are suitable for most applications where the inlet pressure is relatively constant. In applications where the high pressure supply is subject to large variations, a two-stage regulator with a low SPE will provide the most stable, lowpressure delivery. The degree of variation that Figure 1. Process analyzer with pressure-reducing and back-pressure regulators. can be expected in the outlet pressure differs between one- and two-stage regulators. A high- of the inlet-pressure range. In Figure 1, the inlet pressure varies quality, one-stage regulator will deliver an outlet pressure range by 5 bar (35 to 40 bar), so 5 bar x 0.01 equals an outlet pressure that may be estimated using the following formula: variation of 0.05 bar. If the outlet pressure is set for 2 bar, and â&#x2C6;&#x2020;P (outlet) = â&#x2C6;&#x2020;P (inlet) x 0.01 the inlet pressure rises from 35 to 40 bar, the outlet pressure In other words, the variability in outlet pressure is 1 percent will drop from 2 to 1.95 bar.

the high-pressure (inlet) rising and the low-pressure (outlet) dropping is typical of one-stage regulators. The high-pressure rise causes the valve seat to constrict slightly, reducing the regulator orifice size and the corresponding outlet pressure. A two-stage regulator consists of two one-stage regulators in series and combined into one component (Figure 2). The first regulator reduces the high-pressure supply to an intermediate point between the inlet pressure and the desired outlet pressure. The second stage reduces the intermediate pressure to the desired outlet pressure. To calculate the variability of outlet pressure for a high-quality, two-stage regulator, the inlet-pressure difference is multiplied by 0.0001, or by 1 percent for each regulator (0.01 x 0.01 = 0.0001). In a typical application for a two-stage regulator, a gas cylinder is emptied at a near constant outlet pressure. As the cylinder empties, pressure at the regulator inlet will drop. If, for example, the pressure drops from 175 bar to 5 bar, the inlet pressure variation is 170 bar. If a two-stage regulator is used with a target outlet pressure of 2 bar, then the outlet pressure will drop from 2 to 1.983 bar. On the other hand, if the same gas cylinder were outfitted with a one-stage regulator, the pressure would increase from 2 bar to 3.7 bar. While a two-stage regulator is handy, two one-stage regulators may work just as well, or better in some applications. One example is a cross-over arrangement, where two gas cylinders feed one point of entry (Figure 3). One cylinder is used until its pressure drops below a certain point. The second cylinder then goes into service. This specialized configuration places a onestage regulator with each of the two cylinders. An additional regulator (often referred to as a line regulator) is located at the entry point to the system, so that at all times the gas is passing through two regulators. November/December | 2013

Diaphragm Regulators Diaphragm regulators are generally the most sensitive in response to changes in pressure, especially in low-pressure applications. Depending on their rating, they may be used with inlet pressures up to 248 bar and controlled outlet pressures up to 35 bar. As inlet pressure rises, the thin metal diaphragm flexes up, allowing the poppet to rise into the regulator seat, reducing the effect of the increasing inlet pressure thereby providing a constant outlet pressure. As the inlet pressure drops, the diaphragm flexes down and pushes the poppet out of the seat. This action allows for a flow increase through the regulator, which in turn creates a stabilizing pressure at the outlet. The flexibility of the diaphragm is vital to the long-term performance of the regulator.

or polymeric seals. The use of a backing plate between the diaphragm and the cap assembly can guard against diaphragm rupture. The backing plate is a sturdy stainless steel disk that can also help to apply uniform pressure across the entire surface of the diaphragm. The poppet is a critical piece in a diaphragm regulator. Generally made of a high-grade stainless steel, such as S17400, the poppet is electro-polished to provide a high-tolerance seat seal. In a pressurereducing regulator, the poppet is springloaded and held vertically in the inlet channel, with the tip in constant contact with the diaphragm. With the poppet pushing up and the diaphragm pushing down, the two work together toward the desired balance. The poppet closes or opens the regulator inlet as its conical shape fits against a precision machined seat. A damper fitted to the bottom of the poppet supports and centers the poppet to reduce noise and vibration in high-flow conditions. With stainless steel regulators for high-purity applications, particular attention should be paid to the materials of construction for the diaphragm and poppet seat. For the diaphragm, an alloy such as Inconel may be more appropriate than Type 316 stainless steel due to IncoFigure 3.

CFPA Corner

Moving FORWARD The Canadian Fluid Power Association plans for the future.

By John Lamb, Chair, Canadian Fluid Power Association

ver the past year, the Canadian Fluid Power Association (CFPA) has been working hard to provide true value for our membership and reconfirm our national identity. The CFPA has clearly identified our value proposition and is continuing to provide the important services our members have been requesting. Our goal is to have a membership that is strong and involved while keeping it uniquely Canadian. We have seen resurgence in membership through the creation of new sub-committees which offer the opportunity to work on specific topics in small teams. These sub-committees form the Four Pillars of the CFPA and are structured to create value and interest for our members on different topics which are deemed to be at the core of our association. The Four Pillars are: Market Insight, chaired by John Lamb, provides statistical information specifically for our Canadian fluid power marketplace. Education, chaired by John Bachmann, has been a cornerstone of the CFPA since its inception and continues to increase awareness of our fluid power industry. Industrial Relations, chaired by Doug Newton, has a mandate to provide an information conduit to our members regarding fluid power industry regulations and certifications. Communcations, chaired by Alan Wheatley, is responsible for media outreach, updates to the CFPA website and regional/ national events. We are also updating our membership throughout the year with our newsletters. Having the ability to share our message to the Canadian Fluid Power industry through our media part-

ners is very important. Throughout the year, CFPA Directors travelled across Canada to reach out to our membership as we want to understand and appreciate regional differences within the fluid power industry. In early 2013, we held a regional meeting in Calgary, AB where we enjoyed a presentation on global energy requirements and the oil sands. Western members organized a golf tournament in Red Deer, AB during the summer, which has become a great western tradition. We held another regional meeting in Montreal, QB where we learned the importance of social media as it relates to business. CFPA plans to increase our social media outreach in 2014. In September, we held our 2013 Annual General Meeting (AGM), which was held in Niagara-on-the-Lake, ON. The meeting offered membership the opportunity to network with fluid power industry leaders while enjoying a great game of golf or taking a tour of a world class Niagara Winery. During the main meeting, we enjoyed the inspirational true story of Jeff Adams, a Canadian 13-time and gold medal winner in the Paralympics as well as the CEO of Icon Wheelchairs. The Toronto-based company makes customized wheelchairs that are also reconfigurable to adapt to the user’s changing needs. We also heard about Gen Y and how understanding generational differences can impact business. We had workshops on topics related to our Four Pillars as member participation is a key to our success. As we look ahead, the CFPA will to continue stepping forward and offering the services that are important and relevant to our membership. We will continue to reach out and understand our members’ needs while providing industry knowledge to help them reach their companies’ goals. DE www.cfpa.com

BIONIC Eyeglasses Ottawa-based eSight’s hands-free intelligent eyewear allows those with 20/60 to 20/400 eyesight read or recognize faces for the ﬁrst time.

Canadian high-tech goggles restore sight to legally blind and low-vision individuals. By Treena Hein

ecessity, as we all know, is the mother of invention. In the case of Conrad Lewis, it was the critical necessity of providing sight for his two sisters, who were legally blind due to Stargardt’s Disease. There was nothing that could be done medically, but Conrad believed he could develop an engineering solution that would restore their sight. “Everyone said it couldn’t be done, but he was sure he could prove them wrong,” explains Kevin Rankin, who is president and CEO of eSight Corporation, the Ottawa-based company Lewis founded. “He wanted to help his sisters and change the lives of millions around the world.” Lewis started eSight in 2007, beginning his quest with a small team of researchers and engineering developers. Head-mounted displays for the visually impaired had already been created by that time, but they were too large, heavy and awkward to be practical. They also lacked the realtime image processing that would have made them truly effective. The eSight team set to work to solve these issues, developing November/December | 2013

two generations of prototypes over the next few years. Test after test, solution after solution, they achieved a pre-production version in mid–2012 and fully launched the product this year. Many private and government agencies provided support along the way, including angel investors from Canada and the U.S., the NRCIRAP Industrial Research Assistance Program, the Federal Economic Development Agency for Southern Ontario’s Investing in Business Innovation Initiative and the Southern Ontario Fund for Investing in Innovation, Ontario Centres of Excellence and MARs Discovery District Investment Accelerator Fund. eSight eyewear employs several integrated components. First, an advanced, high-resolution video camera captures what the wearer is looking at. Those video images are then relayed to a controller, where sophisticated software processes the images in realtime and projects them onto two LED screens in front of the wearer’s eyes. The technology is customized to provide vision as near to normal as a person’s condition allows, providing improved distance, near and intermediate range vision to those with macular degeneration, diabetic retinopathy, Stargardt’s Disease, ocular albinism and other conditions.

28 CoverStory It includes the wearer’s prescription lenses and enables people with low vision to see in a number of ways. First, the eyewear can magnify an image up to 14 times. It also auto-focuses to enable the wearer to read at a normal distance and then look up and view something in the distance. There are also contrast settings and colour modes that can be adjusted to best suit how a person prefers to see. For example, he may prefer to read white on a black background versus the reverse. Regarding blind spots, Rankin says the improvement eSight provides depends on the individual. Some users have informed the company that their blind spot completely disappears, while in others it is significantly diminished. “The effect this technology can have on the lives of people with vision loss is remarkable,” says John Rafferty, president and CEO of CNIB (formerly known as the Canadian National Institute for the Blind). “It’s an exciting device that can enable some people to recapture activities they haven’t experienced in decades, like watching their kids play soccer or reading the Sunday morning newspaper.”

allow users to control features such as zoom. Among the mechanical challenges was achieving high-precision alignment of the displays with the user’s eyes. “We really needed innovative approaches to position the displays correctly for individual users,” Jones says, “and to allow the device to pivot between a heads-up mode and an immersive mode while integrating a user’s unique prescription lenses.” “Everything was difficult, and there were many nights when we went home wondering if the naysayers weren’t right,” Jones admits. “But we had a highly motivated team that would not give up.” In addition to their own innovative ideas, staff was also able to consult with the company’s advisory board, which includes experts such

perceptible lag. The software system developed by the eSight team ended up including several control and image processing sub-systems, with low-latency application software that allows a captured image to be processed and enhanced on a frame-by-frame basis before being served up to the user on the near-to-eye displays. At the same time, the team needed the right hardware. “We looked at electronic components available on the market, but as is often the norm in developing breakthrough technology, their physical size and performance requirements just didn’t meet the needs of the end-customer,” notes Director of Development Frank Jones. “In particular, no off-the-shelf camera system met our requirements, and so appropriate components for image capture and lens control needed to be designed and developed.” In addition, near-to-eye display systems were – and still are – not yet mass-market, so the team put significant effort into component customization, under strict weight and volume constraints. In integrating the entire device, the realtime operating system needed to be ported to these specialized hardware components. A multi-threaded application environment was developed to handle the realtime image capture and display system that would also November/December | 2013

as Dr. Graham Strong (low vision rehabilitation optometrist and director of the Centre for Sight Enhancement at the University of Waterloo School of Optometry) and Dr. Rejean Munger (senior scientist at the Ottawa Health Research Institute, and an assistant professor of ophthalmology at the University of Ottawa Faculty of Medicine). Jones says overall integration and sticking to the product development schedule were likely the biggest challenges in getting the product to market. “With each design element presenting unique and difficult issues, it would have been very easy for the product development schedule to go off the rails,” he notes. “But with careful project management and control, we were able to engage excellent designers, developers and subcontractors to deliver our current production system on time and on budget.” Currently, the eSight team is working to expand the capabilities of its eyewear. In its current form, the device already addresses a large range of vision problems, but software enhancements will extend that even further. There are other technologies in the works as well, obviously under wraps for now. Speaking on behalf of the entire company, Rankin says it feels “amazing” to be finally helping people keep their independence or gain more independence than they’ve ever had. “When we see a child who is legally blind, reading and giggling, and the tears in her parents’ eyes, it is nothing short of awesome,” he says. “Our little company in Kanata, Ontario, with less than 20 people, developed a world class innovation that enables people who are legally blind, to actually see. We are very fortunate to be able to do such meaningful work.” DE www.esighteyewear.com www.design-engineering.com

The Art of MOTION CONTROL EtherCAT synchronizes movement of 1,216 servo axes in kinetic sculpture.

ir passengers and airport visitors who enter Terminal One at Changi Airport in Singapore are greeted by “Kinetic Rain”, a kinetic sculpture flowing gracefully above them as they make their way through the modernized check-in hall. Mimicking the movement of tropical rain, the installation consists of 1,216 copper-plated aluminum droplets, suspended from the ceiling on thin steel wires, and each individually moved by a small servomotor. During a 15-minute show, the droplets form into different dynamic shapes all connected by the theme of flying. The installation consists of two contiguous fields of 608 droplets each, extending over a total area of more than 800 square feet and plays over a room height of nearly 24 feet. The artistic concept for the installation came from Art+Com, a Berlin-based agency specializing in spatial design. The technical implementation and programming of the overall project was accomplished by MKT AG from Olching, near Munich, Germany. MKT AG, experts in kinetic installations, took care of the complete technical implementation, including the software. “In ‘Kinetic Rain’ we have realized the most sophisticated project of this type to date,” says Axel Haschkamp, Director of MKT AG. “More than 2,000 engineer hours flowed into this project. Particularly challenging was the transport to Singapore of the fully pre-assembled installation weighing over 30 tons.” The challenge of moving 1,216 servo axes synchronously was solved on the basis of Beckhoff ’s EtherCAT industrial Ethernet technology, TwinCAT automation software and compact EL7201 EtherCAT Terminals that function as servo drives.

How It Works “The synchronous movement of 1,216 axes is one of the absolute highlights of this project,” says Raphik Shahmirian, sales representative for Beckhoff in Munich. The demands on the control of “Kinetic Rain” are extraordinarily high, with the precise movement of 1,216 axes. In addition, the project demanded high availability, compact design of the components, and the replacement of components without addressing. “One of the top specifications from our customer, Changi Airport, was that the system must run 24 hours a day. Even if an individual axis were to fail, the show must go on,” said Peter Haschkamp, MKT. Beyond that, high requirements had to be met where dynamics, precision and speed of the motion sequences were concerned. The droplets move at a speed of 1.5 m/s and an acceleration of 1.4 m/s². The movement must be dynamic, but at the same time, flowing and absolutely free of jerks. MKT found their solution with the PC- and EtherCAT-based Beckhoff control platform along with compact servo drive technology. A central C6525 Industrial PC is responsible for the control. It communicates via TwinCAT ADS (Automation Device Specification) with a special GUI computer from MKT. At the same time, the PC centrally controls the 1,216 axes via TwinCAT NC PTP and acts as the master. Via the TwinCAT cam table function, the master PC coordinates the distribution of the position data to the six slave PCs, which each are assigned 192 or 208 axes and ensures the synchronicity of all axes according to a master axis as reference. The GUI computer from MKT serves for visualization, but also contains the show in the form of a table, ensuring the position data for each droplet at time intervals of 200 ms, www.design-engineering.com

WATERS

The robotic Kingfisher autonomously collects hydrographic data in hazardous and remote locations.

Clearpath Robotics’ Autonomous Surface Vehicle automates the environmental engineering profession’s dirtiest and deadliest jobs. By Mike McLeod

n many mining operations, tailings ponds pose a particularly difficult logistic and environmental challenge. Tainted by toxic chemicals, the man-made containment reservoirs require constant management to assure mining by-products don’t cause long-lasting environmental damage. A large part of that work involves a process called dewatering, by which water in the pond is removed in proportion to the new tailings added. Calculating how much water to remove, however, requires knowing how much tailing sentiment has settled on the bottom of the pond. Conducting detailed depth measurements, known as bathymetric surveys, can be hazardous work. Typical measures entail technicians, equipped with sonar or probes, cruising the pond in a tin boat to take readings from various locations—an unappealing and expensive task that often results in inaccurate or incomplete data. Into these dangerous waters sails Clearpath Robotics, a Kitchener, ON-based robotics firm specializing in unmanned vehicles for research and development. Among its turn-key autonomous vehicles, the company is best known for the Kingfisher, an Autonomous Surface Vehicle (ASV) that can survey tailing ponds and other remote or hazardous water environments. “There are some fairly significant health and safety concerns with having people in fast, cold or polluted water, so using a robotic system helps minimize that safety concern,” says Clearpath Robotics CEO, Matt Rendall. “And because it’s so time consuming, the number of data points collected in a manual survey is quite low. What we’ve found with Kingfisher is that, because we can collect hundreds of times more data, we are able to provide much more detailed analytics.” www.design-engineering.com

37-40-DES.indd 37

Water ‘Bot Kingfisher grew out Rendall’s university studies while he and his Clearpath partners—CTO Ryan Gariepy, COO Bryan Webb and VP of Hardware Patrick Martinson—were undergraduates in the University of Waterloo’s mechatronics engineering program. Determined to turn their shared passion for robotics into a business, the group established the company and landed their first contract, a professor who needed a water borne robot for water data collection, before graduation. “Originally, we were only interested in land robots, so when we finished that first contract, we went back to that,” Rendall says. “But people kept coming to us for water and, after three or four requests, we discovered a fairly substantial market opportunity.” Now in its second generation, Rendall says the present Kingfisher M200 is designed to maximize portability, agility and reliability while minimizing the manpower needed to operate it. Measuring 1.3 meter long and just under a meter wide, the ASV weighs approximately 29 kilograms, making easy for one person to transport and deploy. In the water, the vehicle’s 14.4V NiMH battery powers twin water jets (one at the back of each pontoon) that not only propel the electric craft at up to 3.3 kn but also steers the Kingfisher without rudders. This, says Rendall, allows the CSV to navigate shallow waters conventional boats couldn’t while its low center of gravity keeps it stable in variable conditions. “For our use case, we needed a design that would allow our boat to move in a very slow and controlled manner through fast moving water so we created a semi-planing/semi-displacement hull,” Rendall explains. “The reason we went with the catamaran design is that we want to have high stability for the sensors on board since the less stable the boat, the more disturbances in the data collection.” November/December | 2013
