More that 52% of the U.S. highway congestion in urban areas is a direct result of highway incidents. Federal and State transportation authorities are searching for quick, low-cost and efficient highway incident detection and warning systems. Several solutions have been proposed but none could meet the requirements of transportation authorities. Central Signal, funded by federal agencies, has done ...

The TEXAS Model for Intersection Traffic is a high-quality single-intersection microscopic traffic simulation model developed at The University of Texas at Austin. It analyzes in sub microscopic detail the behavior of driver-vehicle units as they go through an intersection and intermix with other traffic flows. It has detailed intersection geometry, path following, microscopic car following, lan ...

In this SBIR Phase I program teaming with the primary ABL system integrator, Advanced Powder Solutions will develop a low cost light weight, high strength, high temperature resistant, iodine, chlorine, helium, ammonia, caustic compatible corrosion resistant composite material. For replacement of current heavier systems, the Phase I program will involve with the fabrication and testing of systems ...

The overall objective of the two phase SBIR program is to develop a hypergolic leak detector (HLD) that can be mounted on the outside of a missile canister which is able to detect rapid changes in concentration that signal leaks of hypergolic rocket fuels and oxidizers. In Phase I Applied Nanotech, Inc. (ANI) established that a solid state gated metal oxide sensors was sufficiently sensitive to p ...

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 ...

ENTECH IS PLEASED TO PROPOSE TO THE STRATEGIC DEFENSE INITIATIVE ORGANIZATION THE DESIGN DEVELOPMENT OF AN INNOVATIVE DOME FRESNEL LENS/GALLIUM ARSENIDE PHOTOVOLTAIC CONCENTRATOR ARRAY, CAPABLE OF ACHIEVING AN AMO OPERATIONAL ARRAY EFFICIENCY OF 20.4% IN THE SPACE ENVIRONMENT. THE PROPOSED SYSTEM WILL UTILIZE THREE HIGHLY INNOVATIVE FEATURES: (I) A DOME FRESNEL LENS CONCENTRATOR WHICH WILL PROVIDE ...

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 ...

Oxide coatings previously developed to protect polyimide and carbon/carbon composites in low earth orbit are brittle and crack upon flexing. Adding small amounts of polytetrafluoroethylene (PTFE) increases coating flexibility but reduces atomic oxygen (AO) resistance and mechanicall durability. Coatings developed in this project will use inorganics with potentially greater flexibility (such as she ...
