MOUTHSTICKS OR ORTHODONTIC ORTHOSES ARE WIDELY USED BY PEOPLE WITH SPINAL CHORD INJURIES OR SIMILAR DISABILITIES TO INCREASE CONTROL OVER THEIR ENVIRONMENT. PEOPLE WITH THE ADDITIONAL LIMITATION OF LITTLE OR NO ANTERIOR/POSTERIOR HEAD MOTION MAY BENEFIT FROM AN EXTENDIBLE MOUTHSTICK. HOWEVER, COMMERCIAL EXTENDIBLE MOUTHSTICKS SUFFER IN THAT THEIR ACTION IS OFTEN SLOW, EXTENDIBILITY IS LIMITED, OR ...

AstroPower is developing a two-junction monolithic tandem solar cell composed of (AlxGa1-x)0.51In.49P lattice matched to GaAs for use as the top cell in a three-junction, two-terminal tandem stack. This tunable bandgap material system is capable of current matching, at 2.03eV, in a two-junction monolithic tandem solar cell two terminal design of (AlxGa1-x)0.51In0.49P/GaAs yielding a best case pred ...

ASTROPOWER IS PROPOSING THE DEVELOPMENT OF AN ULTRA-LIGHTWEIGHT, HIGH PERFORMANCE, THIN LIGHT TRAPPING GAAS SOLAR CELL FOR ADVANCED SPACE POWER SYSTEMS. A THIN DEVICE LEADS TO HIGHER PERFORMANCE IN TERMS OF OPEN CIRCUIT VOLTAGE, RADIATION RESISTANCE, AND SPECIFIC POWER. IN A THIN DEVICE, THE INCORPORATION OF LIGHT TRAPPING TO EXTEND THE OPTICAL PATH LENGTH PERMITS GREATER CURRENT GENERATIC THAN CA ...

ASTROPOWER PROPOSES TO DEVELOP A LIGHTWEIGHT, HIGH PERFORMANCE, ULTRA-THIN ELECTROSTATICALLY BONDED GaAs SOLAR CELL WITH COPLANAR BACK CONTACTS. THE INNOVATIVE DESIGN INCORPORATES LIGHT TRAPPING, ADHESIVELESS COVER SLIDE BONDING, AND ELIMINATES GRID SHADING. THIS NOVEL DEVICE WILL EXHIBIT INCREASED EFFICIENCY AND SPECIFIC POWER DUE TO THE HIGHER OPEN CIRCUIT VOLTAGE AND SHORT CIRCUIT CURRENT OBTAI ...

X-ray computed tomography (CT) is widely used in defense, aerospace, and industrial applications. CT provides flaw detection, density measurement, accurate dimensions, morphology, assembly verification, material property analysis, and other vauable information. However, a major limitation of CT has been the inspection time required for 100% coverage of an object, since a single slice through the o ...

We propose to develop in this Phase I SBIR a technique to produce high-energy, multi-aspect radiographic images in near real-time, using a conventional real time radiography (RTR) system. This technique, stereo-pair imaging, will allow three-dimensional analysis of RTR images by producing two views, at different angles, of the object being inspected. The separate views will be generated by taking ...

REMOVAL OF TOXIC METALS FROM WASTEWATER STREAMS HAS BECOME A PROBLEM OF INCREASING NATIONAL IMPORTANCE, AS A RESULT OF INCREASING CONCERN FOR OUR ENVIRONMENT, AND INCREASINGLY STRINGENT WASTE DISPOSAL REGULATIONS. CHROMATOCHEM, INC., HAS DEVELOPED AN ECONOMICAL AND EFFECTIVE NEW TECHNOLOGY FOR THE REMOVAL OF LOW LEVELS OF TOXIC METAL IONS FROM WASTEWATER STREAMS, USING SOLID PHASE EXTRACTION (SPE) ...
