Appareo Systems, LLC, proposes to develop a functional prototype head-mounted position and orientation system (HPOS). The HPOS will be capable of operating in electromagnetic fields of up to 200 volts/meter and will provide at least one degree of accuracy and at least one degree of resolution at a 60 Hz update rate while providing 3 degree of freedom (DOF) information on head orientation, includi ...

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 ...

Laser-induced breakdown spectroscopy (LIBS) and Raman spectroscopy are developing rapidly for chemical and biochemical sensing applications. There is an urgent need for high-sensitivity detectors so as to minimize sample quantity and maximize detection range from the source. In most field-deployable spectrometers, a photo-detector array is used for analyzing the spectral contents. The sensitivitie ...

CERAMICS HAVE BEEN SHOWN TO BE VERY EFFECTIVE IN THE DEFEAT OF A WIDE RANGE OF KINETIC ENERGY (KE) THREATS. HOWEVER, THE USE OF CERAMICS IN ARMORED VEHICLES HAS BEEN LIMITED DUE IN MOST PART TO THEIR HIGH COST. CERAMIC PARTICULATE REINFORCED METAL MATRIX COMPOSITES (MMCS) PRODUCED BY PRESSURELESS LIQUID METAL INFILTRATION ARE INEXPENSIVE RELATIVE TO MONOLITHIC CERAMICS DUE TO THE LOWER COST OF THE ...

Current riverine craft are built in aluminum. Although aluminum is an obvious candidate material for a riverine operating environment, innovative solutions that deliver structural weight reduction to enable higher speeds, greater payload and increased survivability are always desired. Advanced lightweight composite structural armor concepts, comprised of hybrid fiber reinforced materials, grade ...

Sioux Manufacturing Corporation will develop a novel processing method for carbon-carbon composites manufacture with reduced processing time and costs. Current carbon deposition processes are unacceptably slow and expensive. The new feature of our process is the deposition of iron oxide onto the carbon filters to catalyze the deposition of carbon from methane. Laboratory tests have shown that this ...

Based on multiple technology platforms and theoretical analyses, in the Phase I program we have demonstrated the feasibility that RF polymers with desirable high frequency properties can be achieved. Following Edison¡¯s model of product and process development for technology innovations, Phase-II will pursue further incremental improvement in material properties upon the concept-proving materi ...

IN THE TREATMENT OF THE DYNAMIC PROBLEMS OF STRUCTURES, TWO ALTERNATE TESTING METHODS, BASED ON EXTERNAL AND EMBEDDED SENSORS, EXIST IN THE LITERATURE. IF THE SENSORS RESPOND TO THE CHANGES IN THE DYNAMIC CHARACTERISTICS OF THE STRUCTURE, AND/OR THE ENVIRONMENT, THEN THEY ARE REFERRED TO "SMART" STRUCTURES. SMART SENSORS AND SMART MATERIALS HAVE BEEN USED FOR DETECTING STRUCTURAL DAMAGES AND/OR CO ...
