THIS PROPOSAL COVERS THE DEVELOPMENT OF A CRYOCOOLER WITH A REFRIGERATION CAPACITY OF 0.75 WATT AT 20 KELVIN. THE CRYOGENIC UNIT WILL HAVE A VOLUME OF LESS THAN 16 CM3, AND CAN PROVIDE COOLING FOR 5 MINUTES AFTER A COOLDOWN PERIOD OF LESS THAN 20 SECONDS. THE CRYOCOOLER USES A NEW FABRICATION TECHNIQUE THAT LEADS TO A HIGH RELATIVE EFFICIENCY WITH A MINIMUM VOLUME.

ACTIVATED STEEL FOIL FABRICATED INTO ELEMENTS TO BE PACKAGED AS EXPENDABLE DECOYS HAS SHOWN GOOD PERFORMANCE IN LOW IR SIGNATURE APPLICATIONS. THE PRESENT BATCH PRODUCTION PROCESS FOR THESE FOILS ENTAILS, IN PART, TWENTY HOURS OF FURNACE TREATMENT. A COMBINATION OF NINE SEPARATE OPERATIONS, LOW PRODUCTION RATES AND HIGH LABOR COSTS YIELDS A UNIT MANUFACTURING COST OF MORE THAN $250.00. WE PROPOSE ...

THIS PROPOSAL ADDRESSES THE TECHNICAL CHALLENGE TO U.S. INDUSTRY FOR DEVELOPMENT OF CONTROL SYSTEMS THAT ARE ADAPTABLE TO CHANGES IN THE COMPLEX MULTIPLE, CONCURRENT PROCESSES OF A SEMICONDUCTOR MANUFACTURING ENVIRONMENT. THE PROPOSED WORK IS EXPLORATORY RESEARCH WHICH WILL RESULT IN THE DEVELOPMENT OF AN ABSTRACT SETTING FOR THE CONTROL SYSTEMS, INVOLVING A THREE TIER HIERARCHICAL APPROACH, WITH ...

THE DESIGN OF FEEDBACK CONTROL LAWS FOR SYSTEMS WITH UNKNOWN PARAMETERS AND OTHER SIGNIFICIANT UNCERTAINTIES IS A FUNDAMENTAL PROBLEM IN THE AREA OF AEROSPACE VEHICLE CONTROL. THE APPLICATION OF DISTURBANCE ACCOMMODATING CONTROL (DAC) THEORY TO THIS AREA HAS RESULTED IN A REVOLUTIONARY APPROACH TO THE DESIGN OF ADAPTIVE CONTROL LAWS. THIS APPROACH HAS PROVEN TO BE EXTREMELY EFFECTIVE WHILE, AT THE ...

CONTINUOUS, FULL POWER OPERATION OF HIGH OUTPUT SEMICONDUCTOR DEVICES IS GENERALLY LIMITED BY THE HEAT DISSIPATION CAPABILITY OF THE DEVICE PACKAGE. EXISTING COOLING SCHEMES REQUIRE COOLING PUMPS AND SECONDARY RADIATORS, WHICH LIMITS THE APPLICATION OF THESE DEVICES TO LARGE VEHICLES. THIS PROPOSAL CONCERNS THE ANALYSIS AND DESIGN OF A THERMAL PACKAGE WHICH IS CAPABLE OF DISSIPATING HIGH HEAT FLUX ...

THE NAVY DESIRES AN OPTICAL CORRELATOR SYSTEM TO DETERMINE AIRCRAFT PARAMETERS DURING THE TERMINAL PHASE OF LANDING ON AIRCRAFT CARRIERS. THE FOUNDER OF ADVANCED OPTICAL SYSTEMS, INC. (AOS) CONCEIVED AND DEVELOPED A SERIES OF OPTICAL CORRELATORS FOR MISE. TERMINAL GUIDANCE AND FOR SMART BOMBS. WE DEVELOPED A MULTICHANNEL TRACKING CORRELATOR WHICH WE PROPOSE TO APPLY TO THE AIRCRAFT LANDING PROBLEM ...

PROPOSAL FOR UTILIZING SOLID STATE PIEZO-RESISTIVE SENSORS TO MEASURE AND RECORD CUMULATIVE WHEEL ROTATIONS. WHEEL ROTATION IS SENSED BY EXPLOITING THE FORCE DUE TO NORMAL (CENTRIPETAL) ACCELERATION, WHICH IS A FUNCTION OF THE ROTATIONAL SPEED SQUARED. THE ELECTRONIC PACKAGE IS SMALL (INCORPORATING SMT) AND CONSISTS MAINLY OF THE SENSOR AND A MOTOROLA F68HC11 MICROPROCESSOR. THE MICROPROCESSOR IS ...

THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP IMPROVED DETECTION AND CLASSIFICATION ALGORITHMS FOR TACTICAL AIRBORNE MILLIMETER WAVE (MMW) SEEKERS EMPLOYING POLARIMETRIC PROCESSING. THE PROPOSED RESEARCH IS BASED UPON NONCOHERENT TARGET INFORMATION (NTI) FEATURES (1) EXTRACTION BY WIDEBAND CIRCULAR POLARIZATION DUAL-CHANNEL ACTIVE MMW SEEKERS. THE NTI FEATURES ARE NEAR-COMPLETE IN TARGET INFORMATIO ...
