Industry Update: Analysis & Simulation Software

In our annual poll of executives at leading analysis and simulation software vendors, we found that more widespread use of the cloud, mobile devices, and touchscreen interfaces will be major trends for 2013. These trends will require that vendors take a careful look at their software interfaces to evolve accordingly.

Grand Prize Winner

Sensordrone: A Practical, Tricorder-Like Platform for Consumers and Mobile Device Developers

Mark Wagner, Ben Madoff, and Mark Rudolph Sensorcon, Buffalo, NY

What if sensors, meters, and instruments were just apps instead of single-purpose, bulky, expensive equipment? Sensordrone is a first step towards making this a reality.

LumEN: Luminescent Solar Concentrators for Sustainable, On-Demand Electricity Production

Gianmarco Griffini, Massimo Micocci, and Francesca Ostuzzi, Politecnico di Milano, Milan, Italy

Lum-EN is the first portable device able to harvest solar energy and deliver electrical energy on-demand, employing organic luminescent solar concentrators (OLSCs). High light-to-electricity efficiencies can be attained with little use of conventional solar cells.

Grid-X Cloud and Smartphone Accelerator

James Awrach SeaFire Micros, Beverly, MA

Supercomputers are linked worldwide, creating ultra-highperformance cloud, utility, and grid computers. The Bandwidth-Delay Product (BWDP), where “delay” is the roundtrip time for data transfer, defines required buffer memory. Grid-X addresses BWDP, and enables faster local and globally distributed supercomputing at lower power and cost. SeaFire also created a variant called Grid-X Mobile for smartphones.

Thermal Stir Welding Process

Jeff Ding NASA Marshall Space Flight Center, Alabama

The patented thermal stir welding process is a new solid-state (meaning the weld metal does not melt during welding) welding process invented at NASA’s Marshall Space Flight Center. The unique welding process de-couples the heating, stirring, and forging elements of friction stir welding, and allows for the independent control of each element of the weld process. An induction coil first heats the weld joint material to a desired plasticized temperature, at which time the weld joint material moves into a through-thickness stir rod that stirs the already plastic material. The stir rod can be independently controlled to rotate at a desired rotational speed or RPM. Upper and lower non-rotating containment plates, also independently controlled, compress or squeeze the plastic weld zone to consolidate the plasticized material as it is being stirred. The stir rod protrudes through the center of the upper containment plate, through the weld material thickness, and is captured by the lower containment plate.

Prosthetic Leg Connector

Dave King Synergy Tech, Kelowna, BC Canada

This is a device to aid those who wear prosthetic limbs. The current state of the art is a multilayer system that consists of a cotton sock and a silicone rubber sock that fits over the limb. The prosthesis can attach to the silicone sock by means of a rod and ratchet device. In the case of an artificial leg, the user places the rod into a receptacle in the leg and steps into it. The ratchet then holds onto the rod. However, this can cause problems for patients who are physically weak or who suffer from tenderness in the remaining upper leg. That is enough to stop the patient from trying to use the prosthesis. This device replaces the silicone sock and allows for much easier “application” and better comfort.

LIFE PACK Hypothermia Prevention

Floatation Device Dwight and Jane Cushman, Village Memorial, Portland, OR

Even with floatation gear, when a person who is not prepared for the cold falls into cold water (temperatures of 52 °F or less), the shock of the cold alone can be fatal. Most people who die of hypothermia do so in the first few minutes from failure to breathe or to sustain their heart. The LIFE PACK floatation device is designed to offer protection from coldwater temperatures, and the wearer can hold a child hands-free in water.

Aquaback Water Purification System

Bill Zebuhr, Scott Newquist, David Dussault, E. Andrew Condon, Steven Sahagian, Nicholas Wong, Michael Easton, William Burie, Charles Blanchard, and Nicole Sandoval, Aquaback Technologies, Tewksbury, MA

A highly efficient, low-cost, lowmaintenance, compact, modular vapor compression distiller is designed to be the water processing module in a wide variety of water processing systems to clean incoming water or reclaim waste water. The systems will enable recycling of most water for any use, including potable water, at a lower overall cost than any other technology or combinations of technologies, addressing water supply and disposal problems worldwide. Distillation provides the highest-purity water in a single operation, but until now, distillers have been too expensive to make or operate to be practical. Aquaback has optimized every aspect of distillation using the known vapor compression method to recycle over 99% of the heat of vaporization using a mass-manufactured, self-cleaning design.

Re-Thinking Automotive Tire Pressure Monitoring Systems

Ivan Batinic, ATPS, Inc., San Martin, CA

The ATPS system is a new approach to implementing vehicular Tire Pressure Monitoring Systems (TPMS) that is more economical and ecological than existing systems. A passive, non-electronic sending unit (inside the tire) eliminates RF electronics, thermal compensation issues, raising of the RF noise-floor, and wasteful consumption of limited lithium resources for batteries. The TPMS is comprised of two fundamental components per wheel/tire assembly: an in-tire transducer, and an external, statically mounted chassis sensing component. Signal processing is performed by direct 2- or 3-wire sensor interfaces.
