The Award database is continually updated throughout the year. As a result, data for the given year is not complete until April of the following year. Annual Reports data is a snapshot of agency reported information for that year and hence might look different from the live data in the Awards Information charts.

  1. OPTICAL MULTIPLE ACCESS TECHNIQUES FOR ON-BOARD ROUTING

    SBC: MENDEZ R&D ASSOCIATES            Topic: N/A

    TEMPORAL AND SPECTRAL CODE-DIVISION, MULTIPLE ACCESS (CDMA) TECHNOLOGIES HAVE IDEAL PROPERTIES FOR SATELLITE ON-BOARD ROUTING: THEY LEND THEMSELVES TO ASYNCHRONOUS BROADCAST MODES WITH NO OVERHEAD OR LATENCY. ALSO, WHEN THE NETWORK IS INITIALLY OVERDESIGNED (IN THE SENSE OF HAVING MORE CODESTHAN USERS), ITS EXCESS CAPACITY CAN BE USED FOR REDUNDANCY (RELIABILITY) OR FOR LIVE INSERTION OF NEW USERS ...

  2. MONOLITHIC GAAS UHF IF SWITCH MATRIX FOR SPACE STATION APPLICATIONS

    SBC: Microwave Monolithics Inc.            Topic: N/A

    THE SPACE STATION MULTIPLE ACCESS COMMUNICATION SYSTEM WILL PROVIDE THE PRIMARY TELEMETRY, VOICE, AND VIDEO LINK BETWEEN CREW MEMBERS AND EXTRAVEHICULAR ASTRONAUTS. THE HEART OF THIS SYSTEM, WHICH IS BASED ON A FREQUENCY DIVISIONMULTIPLE ACCESS (FDMA) SIGNAL DISTRIBUTION SYSTEM WITH MULTIPLE DIRECTIONAL ANTENNAS ON BOTH THE SPACE STATION AND THE ASTRONAUT(S), IS THE INTERMEDIATE FREQUENCY (IF) SWI ...

  3. ADVANCED MONOLITHIC GAAS RECEIVER FRONT END FOR SPACECRAFT TRANSPONDER APPLICATIONS

    SBC: Microwave Monolithics Inc.            Topic: N/A

    MICROWAVE MONOLITHICS INCORPORATED (MMINC.) PROPOSES TO DEVELOP AN ADVANCED X-BAND GAAS MMIC RECEIVER FRONT END FOR SPACECRAFT TRANSPONDER APPLICATIONS. THIS COMPONENT WILL CONSIST OF, AT MOST, THREE GAAS MMIC CHIPS - A LOW NOISE AMPLIFIER, A MIXER/IF AMPLIFIER, AND A VOLTAGE CONTROLLED DIELECTRIC STABILIZED OSCILLATOR WITH ON-CHIP MICROWAVE FREQUENCY DIVISION CIRCUITRY. A HYBRID FIRST STAGE, POSS ...

  5. EVALUATION OF PS200 PLASMA COATING IN AN AIR-COOLED ROTARY ENGINE.

    SBC: Moller International, Inc.            Topic: N/A

    RECENT TESTS HAVE INDICATED THAT A THERMAL BARRIER COATING ON AN AIR-COOLED ROTARY ENGINE SIDE HOUSING RESULTS IN SURFACE TEMPERATURES BEYOND THE CAPABILITY OF CONVENTIONAL HYDROCARBON LUBRICANTS. PS200 IS A PLASMA APPLIED COATING OF CHROMIUM CARBIDE WITH SILVER AND A FLUORIDE EUTECTIC FOR HIGH TEMPERATURE LUBRICITY. IT WAS DEVELOPED BY HAROLD SLINEY OF NASA LEWIS AS AN UNLUBRICATED WEAR COATING F ...

  6. UNSTRUCTURED TRIANGULAR MESH/NAVIER-STOKES METHOD FOR AERODYNAMICS OF AIRCRAFT WITH ICE ACCRETION

    SBC: NIELSEN ENGINEERING & RESEARCH, INC.            Topic: N/A

    ICE ACCRETION ON COMPONENTS OF BOTH FIXED WING AIRCRAFT AND ROTORCRAFT CAN CAUSE AERODYNAMIC PENALTIES SUCH AS INCREASEDDRAG, DECREASED LIFT, REDUCED STALL ANGLE, INCREASED STALL SPEED AND INCREASED ENGINE HORSEPOWER REQUIREMENTS. THERE IS CURRENTLY A STRONG NEED FOR DEVELOPING ACCURATE AND EFFICIENT ICING SIMULATION METHODS WHICH CAN BE USED IN THE DESIGN OF ICE PROTECTION SYSTEMS, FOR QUALIFICAT ...

  7. NONLINEAR CONTROL OF SHEAR FLOWS

    SBC: NIELSEN ENGINEERING & RESEARCH, INC.            Topic: N/A

    N/A

    SBIR Phase I 1991 National Aeronautics and Space Administration
  8. NEURAL-NETWORK PATH-PLANNING AND DIGITAL ADAPTIVE CONTROL OFREDUNDANT ROBOTS

    SBC: Netrologic, Inc.            Topic: N/A

    RESEARCH WORK ON MANIPULATOR CONTROL HAS BEEN CONCENTRATED ON DEVELOPING CONTINUOUS-TIME CENTRALIZED CONTROL SCHEMES. IN PRACTICE, ROBOTS ARE CONTROLLED BY DIGITAL COMPUTERS AND THE SOLUTION OF THE CONTROL PROBLEM BASED ON THE ASSUMPTION OF CONTINUOUS TIME OPERATION CAN LEAD TO DEGRADATION OF PERFORMANCE AND POSSIBLE INSTABILITY OF THE OVERALL SYSTEM. FURTHERMORE, CENTRALIZED ROBOT CONTROLLERS REQ ...

  9. HUMAN-MACHINE INTERACTION IN HUMAN ASSISTED ROBOTIC SYSTEMS

    SBC: Netrologic, Inc.            Topic: N/A

    THIS PROJECT INTRODUCES A NEW CLASS OF ROBOT MANIPULATORS CALLED EXTENDERS. EXTENDERS ARE WORN BY HUMANS AND INCREASEHUMAN MECHANICAL ABILITY WHILE THE HUMAN'S INTELLECT SERVES AS THE CENTRAL INTELLIGENT CONTROL SYSTEM FOR MANIPULATING THE EXTENDER. THE HUMAN BODY, IN PHYSICAL CONTACT WITH THE EXTENDER, EXCHANGES POWER AND INFORMATION SIGNALS WITH IT. THIS PROJECT'S OBJECTIVE IS TO DEVELOP GROUND ...
