THE PRIMARY OBJECTIVE OF THIS PROJECT IS TO PROVIDE THE DESIGNER OF AN TI-RADIATION HOMING MISSILES WITH THE INFORMATION NECESSARY TO STRUCTURE FUTURE STUDIES AND TECHNOLOGY PROGRAMS AIMED AT DEVELOPING AN ANTI- RADIATION MISSILE CAPABLE OF HOMING ON THREAT RADIATION MISSILE CAPABLE OF HOMING THREAT RADARS UTILIZING SPREAD SPECTRUM TECHNIQUES. THIS INVOLVES THE FOLLOWING TWO TASKS: 1. DEFINE THE C ...

THIS RESEARCH ADDRESSES TECHNIQUES AND MATERIALS FOR ON-ORBIT MAINTENANCE AND REFURBISHMENT OF THERMAL CONTROL SURFACE COATINGS USED ON LONG-LIFE SPACECRAFT. IN MANY CASES, CONSERVATIVE ASSUMPTIONS ON THE EFFECTS OF LONG-TERM DEGRADATION HAVE DRIVEN THE DESIGN OF SPACECRAFT THERMAL SYSTEMS TOWARD OVER CAPACITY WHICH RESULTS IN WEIGHT, SIZE, COMPLEXITY, AND COST PENALTIES. IF CRITICAL SURFACES COUL ...

THE DESIGN OF A MECHANICAL, AUTOMATIC HEAT SWITCH FOR USE WITH A REFRIGERATOR IS PROPOSED. EMPHASIS IS PLACED ON OBTAINING A HIGH SWITCH RATIO FOR THE SYSTEM. THE MAIN EFFORT WILL CONSIST OF A CAREFUL THERMAL DESIGN FOR LIMITING THE THERMAL RADIATIVE TRANSFER WHICH WOULD REDUCE THE OFF STATE THERMAL RESISTANCE.

THE INCREASINGLY WIDESPREAD APPLICATION OF MIL-STD-1553B TO MILITARY AND, POTNTIALLY COMMERCIAL AIRCRAFT HAS CREATED A NEED FOR DIGITAL OUTPUT FLOW ANGLE TRANSMITTERS. THE CURRENT MEANS OF GENERATING A DIGITAL OUTPUT FROM EXISITING TRANSDUCERS HAS AN UNFLAVORABLE IMPACT ON SIZE, WEIGHT, POWER, COST AND RELIABILITY. DIGITIAL ENCODING TECHNIQUES ARE BELIEVED TO HAVE BENEFICIAL APPLICATION TO EXISTIN ...

THE POSIDENT CONCEPT USES FINGER PRINT IDENTIFICATION SYSTEM TO COMPARE THE SUBJECTS LIVE FINGER PRINT WITH A STORED FINGER PRINT. THE STORAGE MEDIUM CAN BE ONE OF SEVERAL TYPES. A PHOTOGRAPHIC IMAGEIIS ONE METHOD OF STORAGE. DIGITAL DATA IN PROM IS A SECOND METHOD. THE ID CARD IS PLACED FON THE ELECTRO-OPTICAL CORRELATION DEVICE. A VIDEO CAMERA (VIDICON OR SOLID STATE CCD CAMERA) IS USED TO SCAN ...

VERY LARGE AND ACCURATE REFLECTIVE SURFACES WILL BE REQUIRED FOR FUTURE APPLICATIONS SUCH AS LASER POWER TRANSMISSION, LASER PROPULSION, SOLAR ENERGY COLLECTION, ANTENNAS AND TELESCOPES. PRESENT TECHNIQUES USED TO CONSTRUCT HIGHLY ACCURATE REFLECTORS ARE LIMITED IN APPLICATION TO DIAMETERS OF A FEW METERS (LESS THAN 5). METALLIZED THIN-FILM MEMBRANES HAVE THE POTENTIAL TO SATISFY THE REQUIREMENTS ...
