A CRYOCOOLER CAPABLE OF OPERATING UNDER EXTREMELY HIGH ACCELERATION LEVELS IS PROPOSED. THE CRYOCOOLER USES THE LINDE-HAMPSON CYCLE, AND CAN REACH APPROXIMATELY 80 KELVIN. MULTI-STAGE UNITS, TO REACH LOWER TEMPERATURES, ARE ALSO POSSIBLE.

THIS PROPOSAL IS A UNIQUE AND INNOVATIVE APPROACH TO CONSTRUCTING 2-D GAAS ACOUSTO-OPTIC LIGHT DEFLECTORS FOR HIGH POWER LASER APPLICATIONS WITHOUT THE USE OF MIRRORS. ADVANTAGES OF SUCH SYSTEM OVER CONVENTIONAL LASER BEAM MIRRORS ARE THE INABILITY OF MIRRORS TO DEFLECT AT HIGH SPEEDS DUE TO THE MIRROR'S INERTIA. AS A RESULT WITH ELECTRONIC ACOUSTO-OPTIC DEVICES, THEIR PERFORMANCE AND HENCE SPEED ...

WITH THE INTEREST IN THE DEVELOPMENT OF VERY FAST COMPUTERS, MUCH FASTER THAN THE CONVENTIONAL DIGITAL CHIP-BASED SYSTEM, THE FUTURE SEEMS VERY BRIGHT FOR OPTICAL-SIGNAL PROCESSING. TWO-DIMENSIONAL OPTICAL PROCESSING IS BEING USED FOR PATTERN RECOGNITION, MACHINE VISION, AND OPTICAL COMPUTING. CURRENTLY, A MAGNETO-OPTIC SPATIAL LIGHT MODULATOR (MOSLM) IS USED TO CONVERT ARRAYS OF PROGRAMMABLE ELEC ...

CURRENTLY AVAILABLE ALGORITHMS FOR SYSTEM IDENTIFICATION AND CONTROL ARE NOT COMPLETELY RELIABLE FOR AUTOMATIC IMPLEMENTATION ON MICROPROCESSORS IN REAL TIME. A NEW CLASS OF ALGORITHMS BASED UPON A GENERALIZED SINGULAR VALUE DECOMPOSITION IS BEING CONSIDERED FOR SYSTEM IDENTIFICATION, STATISTICAL MODEL ORDER DETERMINATION, MODEL ORDER REDUCTION, AND PREDICTIVE CONTROL. IN THIS APPROACH, THE ALGORI ...

A LARGE SEGMENT OF SOCIETY-HEARING AND SPEECH IMPAIRED PERSONS-IS CUT OFF FROM THE MAINSTREAM OF SOCIETY BECAUSE IT HAS BEEN BYPASSED BY CURRENT COMMUNICATION TECHNOLOGY. INTEGRATED MICROCOMPUTER SYSTEMS, INC. (IMS) PROPOSES TO RESEARCH, DESIGN, DEVELOP AND EVALUATE AN EFFICIENT AND COST-EFFECTIVE TELECOMMUNICATIONS UNIT TO MEET THE SPECIFIC NEEDS OF HEARING AND SPEECH IMPAIRED USERS TO CALL OR RE ...

CURRENT COMPUTATIONAL APPROACHES ARE INADEQUATE TO PERFORM REAL TIME PATTERN RECOGNITION AND ADAPTIVE RESOURCE ALLOCATION IN ORDER TO SUITABLY RESPOND TO ENEMY THREATS WHEN COMPARED TO THE DYNAMICALLY CHANGING MILITARY ENVIRONMENTS. DESPITE DECADES OF EFFORT BASED UPON STATISTICAL SIGNAL PROCESSING AND PATTERN RECOGNITION METHODOLOGY, THEREAL TIME RECOGNITION OF COMPLEX TARGETS REMAINS A CHALLENGI ...

THE ACQUISITION OF POST BOOST PHASE VEHICLES AND/OR INDIVIDUAL REENTRY VEHICLES BY AN INFRARED SENSOR ON BOARD A SMALL G HARDENED PROJECTILE WHICH SUBSEQUENTLY HOMES ON AND IMPACTS ITS TARGET OFFERS AN ATTRACTIVE APPROACH FOR REENTRY VEHICLE KINETIC ENERGY KILL. THE ACQUISITION, TRACKING, DISCRIMINATION AND GUIDANCE FUNCTIONS REQUIRED OF SUCH AN IR SENSOR RESULT IN A NUMBER OF CRITICAL ISSUES. THE ...

MANY INDIVIDUALS WITH DISABILITIES WOULD BENEFIT FROM IMPROVED METHODS FOR VOICE INPUT INTO, AND VOICE OUTPUT FROM, MICROCOMPUTERS. THE ADVANTAGES OF COMPUTERIZED VOICE OUTPUT FROM PRINTED MATERIAL FOR BLIND OR VISUALLY IMPAIRED INDIVIDUALS IS OBVIOUS. VERY OFTEN, INDIVIDUALS WITH LANGUAGE-LEARNING DISABILITIES FALL INTO THIS CATEGORY. THEADVANTAGES OF SYNTHESIZED SPEECH IS OBVIOUS FOR INDIVIDUALS ...

THE DEVELOPMENT OF HIGH POWER, HIGH REPETITION RATE CLOSING SWITCHES HAS RECENTLY BECOME IMPORTANT FOR MANY PULSED POWER APPLICATIONS. HISTORICALLY, HIGH REPETITION RATE SWITCHES FOR PULSED POWER APPLICATIONS HAVE EITHER BEEN SPARK GAPS OR THYRATRONS. THYRATRONS HAVE HIGH REPETITION RATES, BUT ARE LIMITED TO LOW VOLTAGES AND LOW CURRENT. CONVERSELY, SPARK GAPS CAN CARRY HIGH CURRENTS AND STAND-OFF ...

MANY OF THE SYSTEMS FOR SDI INVOLVE PULSE POWER AND HIGH VOLTAGE SYSTEMS, INCLUDING LASERS, PARTICLE BEAM ACCELERATORS, AND RAILGUNS. ONE OF THE SIGNIFICANT PROBLEMS YET TO BE SOLVED IN DEVELOPING OPERATIONAL SDI SPACECRAFT IS THE MANAGEMENT OF ELECTRIC FIELDS WITHIN THE SPACECRAFT, THE PRIMARY WEAPON SYSTEM, AND ITS POWER SUPPLY AND CONDITIONING EQUIPMENT. THE ELF CODES UNIQUELY HAVE THE ABILITY ...
