A SOLID STATE SWITCH FOR OPERATION AT CRYOGENIC TEMPERATURE IS BEING DEVELOPED THAT WILL PROVIDE MULTI-MEGAWATT POWER CONDITIONING IN THE RAPIDLY EXPANDING FIELD OF LOW TEMPERATURE ELECTRONICS. SINCE EXISTING CONTROLLED SWITCHES ARE NOT DIRECTLY SUITABLE FOR CRYOGENIC OPERATION, ONLY A FUNDAMENTAL APPROACH CAN DEVELOP STRUCTURES CAPABLE OF LOW LOSS AND RELIABLE OPERATION IN THE TEMPERATURE RANGE B ...

A PROGRAM IS PROPOSED TO DEVELOP AN INFRARED THERMAL INSPECTION APPLICATION FOR THE EXAMINATION OF BARE AND COATED FIBERGLASS HULL STRUCTURES. PRIOR WORK HAS DEMONSTRATED THE APPLICABILITY OF THE INFRARED APPROACH TO THE INSPECTION OF THIS TYPE OF MATERIAL. SEVERAL TECHNIQUESWILL BE EVALUATED FOR THE APPLICATION OF THE THERMAL LOAD NEEDED TO PERFORM THE TEST. INFRARED THERMOGRAPHY OFFERS VERY RADI ...

THE COOLING REQUIRED FOR THE PROPER OPERATION OF VARIOUS SENSORS AND INSTRUMENTS IS A KEY PROBLEM IN SPACE-BASED FACILITIES. A NOVEL CONCEPT HAS BEEN DEVELOPED AT LONE PEAK ENGINEERING BASED ON THE COMPRESSION OF A GAS TO HIGH PRESSURES USING A SOLID ELECTROLYTE COMPRESSOR. RAPID EXPANSION OF THE COMPRESSED GAS (JOULE-THOMSON EFFECT) CAN BE USED TO COOL SPACECRAFT INSTRUMENTS AND EQUIPMENT. SOME O ...

THE OBJECT OF THIS WORK IS TO DEVELOP A PROOF OF CONCEPT PROTOTYPE BUOY PHOTOVOLTAIC POWER SUPPLY DESIGN WHICH WILL BE A PART OF A SINGLE UNIT INSTALLED ON A BUOY'S STRUCTURE. THIS SYSTEM INTERFACES WITH A STATUS MONITORING SYSTEM FOR COMMUNICATION OF SYSTEM PARAMETERS TO REMOTE MONITORING STATIONS. DESIGN WORK WILL DEVELOP NEW APPROACHES TO THE UTILIZATION OF SOLAR CELL ARRAYS TO GENERATE ELECTRI ...

THE OBJECT OF THIS WORK IS TO DEVELOP A PROOF OF CONCEPT PROTOTYPE BUOY STATUS MONITOR AND REPORTING SYSTEM DESIGN WHICH WILL BE A PART OF A SINGLE UNIT INSTALLED ON A BUOY'S STRUCTURE. THIS SYSTEM INTERFACES WITH THE BUOY PHOTOVOLTAIC POWER SUPPLY AND THE BUOY POSITION MONITORING SYSTEM FOR COMMUNICATION WITH REMOTE MONITORING STATIONS. THE SYSTEM WILL BE MODULAR AND EXTENDABLE ALLOWING MODULES S ...

THE OBJECT OF THIS WORK IS TO DEVELOP A PROOF OF CONCEPT PROTOTYPE BUOY POSITION MONITORING SYSTEM DESIGN WHICH WILL BE A PART OF A SINGLE UNIT INSTALLED ON A BUOY'S STRUCTURE. THIS SYSTEM INTERFACES WITH A STATUS MONITORING SYSTEM FOR COMMUNICATION OF SYSTEM PARAMETERS AND ALARMS TO REMOTE MONITORING STATIONS. THIS EFFORT WILL EVALUATE LORAN AND GPS POSITIONING SYSTEMS TO DETERMINE WHICH IS MOST ...

A KEY FACTOR IN THE ABILITY TO SAFELY OPERATE A TRAIN IS THEOPERATOR ALERTNESS. OPERATOR ALERTNESS CAN BE COMPROMISED AS A RESULT OF FATIGUE, SUBSTANCE ABUSE OR EMOTIONAL DISTRESS. A DEVICE THAT WOULD OBJECTIVELY REPORT A PERSONS STATE OF ALERTNESS COULD INDICATE THAT PERSONS FITNESS FOR DUTY, FOR EXAMPLE, AT THE BEGINNING OF A SHIFT. IT IS WELL KNOWN THAT ALERTNESS IS HIGHLY CORRELATED WITH VARIO ...

INFRARED SYSTEMS ARE NEEDED FOR A VARIETY OF DEFENSE RELATED APPLICATIONS, SUCH AS: SURVEILLANCE, TARGET DETECTION, ACQUISITION AND TRACKING, MISSILE GUIDANCE, ETC. FOR MANY APPLICATIONS SUCH AS THOSE INVOLVING COLD-DIM TARGETS, THESE SYSTEMS NEED TO OPERATE IN THE VERY LONG WAVELENGTH REGION OF THE INFRARED SPECTRUM, E.G. 15-35 MICRONS CUTOFF. IN THIS WAVELENGTH REGION, THE AVAILABILITY OF SUITAB ...
