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.

Medical Category Winner (Winner of an HP Workstation)

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.

Safety & Security Category Winner (Winner of an HP Workstation)

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.

Sustainable Technologies Category Winner (Winner of an HP Workstation)

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.

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.
