THIS PROPOSAL INVOLVES THE DEVELOPMENT OF WIRELESS HEADSET SYSTEM. THE SYSTEM IS AN APPLICATION OF DIGITAL AUDIO ENCODING, PACKET SWITCHING, LOCAL AREA NETWORKING, AND TIME/ADDRESS MULTIPLEXING TECHNIQUES TO FORM A NETWORK OF PERSONAL ACOUSTIC HEADSETS TO BE WORN BY A NUMBER OF PERSONNEL. THIS INNOVATION ALLOWS THE USE OF MANY HEADSETS ON THE SAME CARRIER FREQUENCY TO OPERATE FROM A SINGLE BASE UN ...

THIS PROJECT IS DEVOTED TO THE DEVELOPMENT OF A UNIQUE COLLECTION OF ALGORITHMS DESIGNED TO RESOLVE SOME OF THE MOST DIFFICULT PROBLEMS OF MODERN COMPUTATIONAL FLUID DYNAMICS: (1) THE ANALYSIS OF COMPLEX INCOMPRESSIBLE FLOWS IN ARBITRARY THREE-DIMENSIONAL DOMAINS; (2) THE ANALYSIS OF COMPLEX FLOW-INTERACTION PHENOMENA ASSOCIATED WITH THE MOTION OF ONE OR MORE RIGID BODIES MOVING RELATIVE TO ONE AN ...

FLIGHT SIMULATION IS A PRIMARY AND CRITICAL FORM OF TRAINING. HOWEVER, CURRENT SIMULATORS HAVE NOT YET BEEN INTEGRATED WITH COMPUTER-BASED TRAINING (CBT) TECHNOLOGY. THIS MEANS THAT AUTHORING TOOLS AND OTHER TYPICAL CBT CAPABILITIES SUCH AS PERFORMANCE MONITORING, GIVING ADVISE TO STUDENTS AND ANSWERING QUESTIONS, AND RECORD KEEPING FUNCTIONS ARE NOT AVAILABLE FOR TRAINING WITH SIMULATORS. WE BELI ...

MULTIROLLER PLANETARY TRACTION DRIVES (FIGURE 1) OFFER A UNIQUE COMBINATION OF COMPACTNESS, HIGH EFFICIENCY AND HIGH TORSIONAL STIFFNESS IN HIGH RATIO DRIVES. THEY HAVE THE ADDED ADVANTAGES OF BACK-LASH FREE OPERATION, LOW NOISE AND VIBRATION, NO GEAR COGGING AND SMOOTH TORQUE TRANSFER IN BIDIRECTIONAL OPERATION. PRESENTLY USED PLANETARY GEAR SYSTEMS SUFFER FROM EITHER BACK-LASH OR LOSS OF EFFICIE ...

MULTICOLOR, DOT MATRIX FLAT PANEL DISPLAYS ARE NOT CURRENTLYAVAILABLE FROM ANY MANUFACTURER - GIVEN FOR TERRESTRIAL USE.PHOTONICS TECHNOLOGY PROPOSES TO DEVELOP SUCH A MULTICOLOR DISPLAY FOR SPACE STATION APPLICATIONS. MONOCHROMATIC AC PLASMA DISPLAYS ARE CURRENTLY BEING SPECIFIED IN HIGH ALTITUDE, MILITARY PROGRAMS. MULTICOLOR AC PLASMA DISPLAYS REPRESENT ONE OF THE LEADING COLOR FLAT PANEL TECHN ...

THIS PROJECT IS AIMED AT DEVELOPMENT OF AN APPARATUS AND A PROGRAM OF RESEARCH WHICH WILL AID IN UNDERSTANDING THE RELATIONSHIP OF AERATION TO NUTRIENT UPTAKE BY PLANTS IN ANYGROWTH SITUATION, BUT PARTICULARILY IN THE CASE OF MICRO-GRAVITY ROOT SUPPORT AND NUTRIENT DELIVERY SYSTEMS. AROOT CHAMBER WILL BE DESIGNED WHICH WILL BE CAPABLE OF CONTROLLING THE ATMOSPHERIC ENVIRONMENT AND THE APPLICATION ...

OVER THE LAST SEVERAL YEARS, THE EPA HAS DEVOTED MAJOR EF- FORTS TO IDENTIFY AND DOCUMENT THE MAGNITUDE OF THE RISKS OFENVIRONMENTAL POLLUTION DUE TO LEAKING UDERGROUND STORAGE TANKS (UST). IN APRIL 1987, THE EPA PUBLISHED THE PROPOSED REGULATIONS FOR THE OWNERS AND OPERATORS OF UST, WHICH ARE EXPECTED TO BE FINALIZEDD IN EARLY 1988. THESE REGULATIONS INCLUDE REQUIREMENTS FOR TANK TIGHTNESS TESTS, ...

THE ADVANCED SOLAR DYNAMIC SPACE POWER SYSTEM UTILIZES A PRECISION OPTICAL CONCENTRATOR TO FOCUS THE SUNS ENERGY FOR CONVERSION TO ELECTRICITY. THE FIRST GENERATION CONCENTRATOR IS MADE UP OF MIRROR FACETS WHICH MUST BE HIGHLY ACCURATE. SOLAR KINETICS PROPOSES TO DEVELOP AN ALL METAL ADVANCED HONEYCOMB DESIGN WHICH WILL MEET OR EXCEED THE ACCURACY GOAL OF ONE MILLIRADIAN SLOPE ERROR. THE MIRROR FA ...

SYSTEMS & PROCESSES ENGINEERING CORPORATION (SPEC) HAS DEVELOPED AN INNOVATIVE ARRAY PROCESSOR ARCHITECTURE FOR COMPU- TING FOURIER TRANSFORMS AND OTHER COMMONLY USED SIGNAL PROCESSING ALGORITHMS. THIS ARCHITECTURE IS DESIGNED TO EX-TRACT THE HIGHEST POSSIBLE ARRAY PERFORMANCE FROM STATE-OF- THE-ART GAAS TECHNOLOGY. THE ARCHITECTURAL DESIGN FEATURES A HIGH PERFORMANCE RISC PROCESSOR IMPLEMENTED IN ...

THE OBJECTIVE OF THE PROPOSED RESEARCH IS DEVELOPMENT OF A SMALL, LIGHTWEIGHT, HIGH CAPABILITY, MULTI-PROCESSOR TELEROBOTIC CONTROLLER SYSTEM. THE SYSTEM IS TO CONSIST OF AN INTERCONNECTION OF SEVERAL ROBOTIC JOINT CONTROLLERS AND A SINGLE MASTER CONTROLLER COMMUNICATING THROUGH A HIGH SPEED SERIAL COMMUNICATION BUS. THE MASTER CONTROLLER CONTROLS COMMUNICATION WITH THE VARIOUS JOINT CONTROLLERS I ...
