COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

A NEED EXISTS TO MONITOR VIBRATION IN HIGHWAY BRIDGES. IT IS DESIRABLE TO MONITOR MANY POINTS ON THE BRIDGE. THE CURRENT PROBLEM IS THAT SENSORS MUST BE WIRED TO A CENTRAL LOCATION. WIRE IS DIFFICULT TO INSTALL AND TO MOVE. THE SOLUTION IS TO COLLECT SENSOR DATA BY RADIO. A SYSTEM EXISTS THAT ELIMINATES WIRE. IT GATHERS SENSOR DATA TO A CENTRAL LOCATION BY RADIO. THE SYSTEM'S UNIQUE FEATURE IS THA ...

Passenger safety concerns have prompted the FAA to elicit energy-sensitive neutron detectors which do not rely on the time-of-flight method and are suitable for use in explosive detection systems. Invocon, Inc. proposes to design an inspection system consisting of an energy source and a detector. Designated FERET sytem, (Field Energy Recoid Emission Technology), it would detect substances identi ...

Polymer Bridge Systems, with over 8 years of research composite bridges, found that success hinges on being dollar-for-dollar cost competitive with steel and concrete. We founded the four "golden rules" that are required: the bridge must be: 1) factory build; 2) road transportable; 3) installed in 1 eight-hour day; and 4) be cost-competitive on an installed cost basis. This bridge will be buil ...

A NEED EXISTS FOR A COMPACT, PORTABLE SYSTEM CAPABLE OF MEASURING DYNAMIC STRESSES INDUCED BY HEAVY TRUCKS IN THE STRU- TURAL MEMBERS OF BRIDGES. USE OF STATE-OF-OF THE-ART ELEC- TRONIC CIRCUITRY NOW ALLOWS CONSTRUCTION OF A HYBRID ANALOG-DIGITAL INDICATOR THATCAN DISPLAY THE PEAK STRESSES A BRIDGEEXPERIENCES BY USING DATA FROM STRAIN SENSORS ATTACHED TO THE BRIDGE. THE FEASIBILITY OF BUILDING SUC ...

Extensive research (Ukraine) has shown that high strength continuous fibers of basalt can be produced. These fibers are inexpensive and have exceptionally high strength, stiffness and corrosion resistance. Basalt is a naturally occurring volcanic mineral, consisting a variety concentration of oxides. The product envisioned is a low-cost, corrosion resistant replacement for steel bar in reinforc ...

U.S. DOT’s Zero Emissions Transportation Initiative is looking to push the transportation sector greenhouse gas production to zero by 2050. This solicitation/topic addresses alternative energy sources for the light vehicle, motorcycle, and bicycle sector. With the continuing significant development in commercialization and availability of biofuels, the possibility exists to meet this goal, with ...
