THE GOAL OF THE PROPOSED PROGRAM IS TO DEVELOP A CURRENT MONITOR SUITABLE FOR MEASURING RF CURRENTS INDUCED IN THE HUMAN BODY. IT HAS BEEN FOUND THAT CURRENTS OF HUNDREDS OF MILLIAMPS CAN BE INDUCED IN A STANDING HUMAN EXPOSED TO VERTICALLY-POLARIZED RF ELECTRIC FIELDS AT A LEVEL OF 1 MW/CM2 IN THE FREQUENCY RANGE OF TENS OF MHZ. LARGE CURRENTS CAN ALSO BE INDUCED WHEN A HUMAN COMES IN CONTACT WIT ...

THE REQUIREMENTS OF SPACE WARFARE DICTATE THE NEED FOR INNOVATIVE TECHNOLOGIES TO SOLVE COMPLEX SPACE OBJECT CLASSIFICATION PROBLEMS. ADVANCES IN COMPUTING SPEED AND EXISTING SOFTWARE TECHNOLOGY ALONE ARE UNLIKELY TO RESULT IN A REAL-TIME DISCRIMINATION SYSTEMS CAPABLE OF MEETING THE COMPLEX REQUIREMENTS OF SPACE OBJECT SURVEILLANCE AND CLASSIFICATION. RATHER, AN ALTERNATIVE METHODOLOGY SUCH AS AB ...

THIS SBIR PHASE I PROPOSAL SPECIFICALLY ADDRESSED 'EARLY STAGE' DEVELOPMENT ISSUES INVOLVED IN APPLYING FIELD EMISSION (FEA) TECHNOLOGY TO BUILD A MONOCHROME, FLAT SCREEN, PAGE SIZE, HIGH CONTRAST, HIGH RESOLUTION DISPLAY. A 90 MM DIAGONAL 700 X 7000 LINE BLACK AND WHITE HE LMET DISPLAY IS THE TARGETED PHASE II PRODUCT. COLOR DISPLAYS AND 138 MM DIAGONAL DISPLAYS ARE TARGETED TO FOLLOW THE INITIAL ...

THE MEASUREMENT OF STRAIN AT HIGH TEMPERATURE IN CANDIDATE NASP MATERIALS IS REQUIRED IN ORDER TO MONITOR MATERIAL RESPONSE UNDER SIMULATED OPERATIONAL CONDITIONS AND TO DESIGN EFFICIENT HOT AEROSPACE STRUCTURES. CONVENTIONAL CONTACT RESISTIVE FOIL STRAIN GAGES ARE NOT SUITABLE FOR HIGH TEMPERATURE MEASUREMENTS DUE TO REDUCED ACCURACY, REQUIREMENT FOR FREQUENT CALIBRATION, AND DEBONDING FROM TEST ...

WITH THE ADVENT OF HIGH-GRADE SOSURCE DEPLETION, ENVIRONMENTAL POLLUTION COSTS AND FOREIGN COMPETITION, BIOHYDROMETALLURGY IS BECOMING BOTH APPLICATION AND COST EFFECTIVE. THE MARKET STRENGTH OF GALLIUM AND GERMANIUM IS INCREASING WHILE DOMESTIC ORES DECREASE. TRA BELIEVE THAT THROUGH BIOLEACHING PROCESSES, US STOCKPILES CAN BE INCREASED AT MINIMUM COST AND MAXIMUM EFFICIENCY.

THE UNITED STATES AIR FORCE IS SEEKING A SIMPLE, LOW COST METHOD FOR MANUFACTURING LARGE SOLID ROCKET MOTORS. LOW COST CONTINUOUS PROCESSING EMPLOYED IN THE COMMERCIAL PLASTICS INDUSTRY SHOULD OFFER THIS POTENTIAL. HOWEVER, THERE ARE UNIQUE PROBLEMS AND REQUIREMENT IN MANUFACTURING PROPELLANTS AND COMMERCIAL CONTINUOUS PROCESSING TECHNIQUES HAVE NOT YET FOUND THEIR WAY INTO PROPELLANT MANUFACTURIN ...

THIN-WALLED TUBULAR STRUCTURES ARE EXTREMELY USEFUL FOR STRUTS AND JOINTS IN LIGHTWEIGHT TRUSSES FOR SPACE PLATFORMS, FOR ANTENNA SUPPORT SYSTEMS, AND, PERHAPS, EVEN FOR WAVEGUIDES. ON THE BASIS OF MASS-SPECIFIC PROPERTIES, GRAPHITE-FIBER-REINFORCED MAGNESIUM (GR/MG) COMPOSITES HAVE THE GREATEST POTENTIAL TO SATISFY AEROSPACE STRUCTURAL REQUIREMENTS FOR STRENGTH AND DIMENSIONAL STABILITY (STIFFNES ...

THIS STUDY INVESTIGATES THE ENHANCEMENT OF AIRCRAFT MUNITIONS LOADING PROCEDURES. PRESENTLY, MUNITIONS ARE TRANSPORTED FROM THE FLIGHT LINE TO THE AIRCRAFT ON A BOMB LIFT TRUCK EQUIPPED WITH A ONE DEGREE OF FREEDOM (DOF) LIFTING ARM. THE ARM CAN RAISE THE MUNITIONS TO THE CORRECT HEIGHT, BUT THE REMAINING FIVE POSITION DOF ARE ACHIEVED MANUALLY THROUGH THE FLEXURE OF THE ARM OR BY REPOSITIONING TH ...

SAR (SYNTHETIC APERTURE RADAR) IS A RADAR IMAGING TECHNIQUE THAT PRODUCES HIGH RESOLUTION MAPS OF THE RADAR CROSS SECTION OF A SCENE BY PROCESSING THE COHERENT PHASE HISTORY OF THE RETURN SIGNAL OVER MULTIPLE PULSES. SAR SYNTHESIZES AN ANTENNA THE LENGTH OF WHICH IS TWICE THE DISTANCE THE SAR PLATFORM FLIES DURING ONE COHERENT DWELL; SINCE THE AZIMUTH RESOLUTION IS INVERSELY PROPORTIONAL TO ANTENN ...

THE OBJECTIVE OF THIS PROPOSAL IS TO CONDUCT PRELIMINARY TESTS ON A NOVEL CHEMISTRY WHICH COULD RESULT IN THE PRODUCTION OF A LOW COST WAFER WHICH CHANGES COLOR UPON EXPOSURE TO WARFARE GASES (WG). SIMILAR WAFERS WHICH WE DEVELOPED FOR OTHER GASES ARE ABOUT 2" X 1" X 1/16" AND WEIGH ABOUT 2.3 GM. THESE CHROMOSENSE (TM) WAFERS CAN DETECT HYDROGEN SULFIDE, ETC. IN 10-30 SEC. AT CONCENTRATIONS OF THE ...
