Transportation Category Winner (Winner of an HP Workstation)

Re-Thinking Automotive Tire Pressure Monitoring SystemsIvan Batinic, ATPS, Inc., San Martin, CAThe 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.

Lightening the Load of Recovery

A unique treadmill, invented by a NASA scientist, supports people trying to get back on their feet.Ask the Denver attorney whose legs were smashed in a car accident. Ask the veterans rehabilitating from injuries sustained while defending the nation. Ask NBA star Blake Griffin, or NFL safety Jim Leonhard, both of whom endured leg injuries playing their sports. Ask U.S. soccer pro Charlie Davies, who returned to the field only a month after suffering life-threatening trauma in a car crash. All will tell you about the benefits of NASA-derived technology.

Determining Key Isotopic Ratios In The Field

On August 6th, 2012 the automatic Mars Science Laboratory rover named Curiosity landed on Mars. One of the scientific instruments on board is ChemCam, which has a pulsed laser capable of ablating a focused spot on a remote sample to create a glowing plasma plume of target material. Light from plasma is collected by rover’s telescope on a mast, and the optical spectra are then analyzed by an internal spectrometer. ChemCam can take thousands of spectra per day from a distance of about 7 meters, thus making chemical analyses on the surface of Mars with unprecedented speed. Operationally, the ChemCam data facilitates decisions of where the rover should be driven.

LED Sensors and Controls Technology

It’s common knowledge that one of the easiest ways to save energy is to shut off lights when they are not in use. Even so, the lighting controls market accounts for a fraction of the overall lighting industry. The market is small, despite the benefits of control technology, because in the past energy consumption was not a high priority. In addition, frequently turning lights on and off reduces the lifetime of light bulbs by as much as three times. LED lighting eliminates traditional lifetime issues and is aligned to enable a rapid growth in the lighting controls market.

Testing LEDs in a Climate Controlled Environment

Though they are a relative latecomer to the world of lighting technology, light-emitting diodes (LEDs) are quickly making up for lost time. Since their invention in 1962, LEDs have been applied in a wide range of lighting applications, including traffic signals, automotive panel lighting, aviation lighting, remote controls, DVD players and other household appliances, just to name a few. LEDs’ functionality and longevity have led to a substantial and growing market share. In fact, a recent study presented at the University of Chicago says that LEDs will capture 60 percent of the global lighting market over the next decade. However, in order to reach that market share, LED lighting devices are subject to an important technical challenge – consistency in the brightness and quality of the light emitted from LED bulbs.

Simulation of Fluid-Structure Interaction in Hydraulic Pump Design

Axial pumps with cam-driven commutation units — so-called PWK pumps — emerged as a result of a research project conducted in the Department of Hydraulics and Pneumatics at the Gdansk University of Technology. As for all axial hydraulic piston pumps, several cylinder chambers are positioned around the rotating shaft of an axial pump with cam-driven commutation units — called PWK pumps. The rotation of the shaft and the attached swash plate leads to movement of the pistons that alternately decreases and increases the fluid volume of the chambers. A window — which is part of the control sleeve or commutating bushing — connects the chamber between the pistons with the low-pressure and highpressure intake and outtake channels.
