AUTONOMOUS TECHNOLOGIES CORPORATION IS DEVELOPING A TECHNIQUE FOR MAKING HIGHLY ACCURATE ANGLE MEASUREMENTS USING A NEW APPROACH TO PROCESSING MONOPULSE HETERODYNE LASER RADAR SIGNALS. THE ADVANTAGE OVER CURRENT MONOPULSE SIGNAL PROCESSING CONCEPTS IS THAT THE EFFECTS OF LASER SPECKLE ARE DECOUPLED FROM THE ANGLE MEASUREMENT. PHASE I CONSISTED OF BOTH ANALYSIS AND SIMULATION WHICH PRODUCED A FOUND ...

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 ...

THIS PROPOSAL OUTLINES A SIMPLE YET ACCURATE APPROACH TO MEASURING THE POSITION AND ORIENTATION OF A ROBOT. THE MECHANISM CAN BE USED TO MAKE BOTH STATIC AND DYNAMIC MEASUREMENTS. TWO VERSIONS OF THE DESIGN ARE PROPOSED; THE FIRST VERSION HAVING HIGH ACCURACY OVER A SMALL WORK VOLUME,AND THE SECOND VERSION HAVING LOWER ACCURACY OVER A WORK VOLUME WHICH WOULD ALLOW POSE MEASUREMENT OVER THE ENTIRE ...

THE DISSEMINATION OF TIMELY WEATHER DATA IS BECOMING INCREASINGLY IMPORTANT AS THE POPULATION DENSITY OF THE UNITED STATES INCREASES. AS THE SOLE GOVERNMENT OPERATED RADIO SYSTEM PROVIDING DIRECT WARNINGS TO PRIVATE HOMES, THENOAA WEATHER RADIO (NWR) SYSTEM IS CRITICAL FOR DISSEMINATING NATURAL DISASTER WARNINGS AND THE TIMELY DISSEMINATION OF WEATHER DATA. THE NEED FOR A LOW COST, REAL TIME COVER ...

THREE ASPECTS OF CLIMATE CHANGE INVOLVING VERY HIGH TROPICAL CLOUDS ARE: (1) WHETHER CHANGES IN HIGH CLOUD PARAMETERS LEAD TO POSITIVE OR NEGATIVE FEEDBACK IN CO2 EFFECTS ON CLIMATIC TEMPERATURE CHANGES; (2) DO CHANGES IN THE HEIGHTS OF CLOUD TOPS AND CLOUD AMOUNT, OR CLOUDS WHICH REACH TO THE TROPICAL TROPOPAUSE, AFFECT THE AMOUNT OFWATER VAPOR IN THE LOWER STRATOSPHERE AND INDIRECTLY THE ANTARCT ...

URANIUM ARC TECHNOLOGY IS BEING DEVELOPED FOR SPACE NUCLEAR THERMAL AND ELCTRIC PROPULSION REACTORS WHERE THE ARC IS DRIVEN MAINLY BY FISSION ENERGY AND REQUIRES LITTLE ELECTRICAL ENERGY INPUT. IT OPERATES AT 10,000K, AND TRANSFERS ITS ENERGY TO THE PROPELLANT OR WORKING FLUID VIA OPTICAL RADIATOR. THE PROPULSION TURBOCHARGER OR AFTERBURNER CAN ELEVATE FLUID TEMPERATURES TO LEVELS ABOVE THE MELTIN ...

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 ...
