Inventor: DOBBS STEVEN K
IPC: F41H5/04
Filed: 1996-12-04
Abstract: A double truss structural armor component includes a first face sheet, an intermediate sheet opposing the first face sheet, a first truss core member sandwiched between the first face sheet and the intermediate sheet, a second face sheet opposing the intermediate sheet, a second truss core member sandwiched between the second face sheet and the intermediate sheet, and laminate materials disposed within interior flutes of the first and second truss core members.  The first truss core member has a flute axis.  The second truss core member has a flute axis which is oriented in a range of about 45° to 90° from the flute axis of the first truss core member.  Thus, a biaxially redundant load path is formed.  The first and second face sheets, the intermediate sheet, and the first and second truss core members are formed of high toughness, high strength titanium alloys.  The laminate materials which are within the interior flutes of the truss core members are bonded to portions of the flutes that are adjacent to the intermediate sheet.  The laminate materials have high energy of break properties.  During impact of a ballistic fragment, one of the face sheets slows down the fragment and flattens and further fragments the fragment.  When the resulting fragments impact the laminate materials, their energies are absorbed by the laminate materials by high strain deformation of the laminate materials in biaxial directions.  Thus, the fragments are brought to rest and are prevented from penetrating the other face sheet  During impact of a blast wave, the energy wave is partially absorbed by one of the face sheets, deforming and transferring load to the truss core members.  These members deform in a buckling mode in biaxial directions, thereby absorbing the blast energy in a spring-like manner, preventing fracture of the other face sheet.

Title: Automatic determination of traffic signal preemption using differential gps
Inventor: JONES GARY V
IPC: G08G1/087
Filed: 1996-04-23
Abstract: A traffic signal preemption system, and a related method for its use, using differential global positioning system (GPS) measurements for accurate monitoring of the position, speed and direction of an emergency or service vehicle approaching a controlled intersection. The preemption system includes a reference GPS receiver, for computing GPS measurement corrections, and a GPS receiver in each vehicle, which transmits its GPS    measure-ments by radio to a receiver located at the controlled intersec-tion. A computer also located at the intersection uses corrected vehicles position, and speed and direction measurements, in con-junction with previously recorded data defining approach routes to the intersection, to determine the optimum time to switch a traffic light controller to preemption mode to permit safe passage of the vehicle. GPS measurement corrections may be applied in a vehicle computer or in the computer located at the intersection.  Other modes of operation of the system include a self-survey mode, whereby the reference GPS receiver determines its own true position by averaging position measurements over a period of a day or two, and a learn mode, whereby the intersection com-puter "learns" unusual approach routes to the intersection as the vehicle traverses the approach routes and transmits position and velocity measurements.
