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 ...

THE INNOVATION IS AN ARTIFICIALLY LAYERED MATERIAL WITH FERROMAGNETIC AND HI-TC SUPERCONDUCTIVE COMPONENTS. THIS HAS BEEN ACHIEVED IN PHASE I BY EXPERIMENTING WITH VARIOUS FERROMAGNETIC AND HI-TC MATERIALS. THE ORIGINAL PHASE I APPLICATION WAS HIGHER SUPERCONDUCTIVE CRITICAL CURRENTS BY PINNING THE MAGNETIC FLUX IN THE FERROMAGNETIC LAYER. HOWEVER, AFTER EXPERIMENTATION IN PHASE I, THE APPLICATION ...
