Abstract: Systems and methods are provided for increasing the geospatial resolution of traffic information by dividing known location intervals into a fixed number of sub-segments not tied to any one map providers format, efficient coding of the traffic information, and distribution of the traffic information to end-user consuming devices over one or more of a satellite based broadcast transport medium and a data communications network. Exemplary embodiments of the present invention detail a nationwide traffic service which can be encoded and distributed through a single broadcast service, such as, for example, an SDARS service, or a broadcast over a data network. Exemplary embodiments include aggregating the traffic data from segments of multiple location intervals, into predefined and predetermined flow vectors, and sending the flow vectors within a data stream to users.

Abstract: A torque sensor having an array of four saturable core magnetic flux detectors arranged in two pairs. Each pair of flux detectors is associated with a pair of magnetoelastic bands. A triangle signal is applied to one end of each pair of flux detectors and an offset correction voltage is applied to the opposite ends. Two amplifiers are associated with each pair of torque detectors and are responsive to the second harmonic of detected flux signals. The signal conditioning electronics provide automatic offset and drift correction.

Abstract: A method and system for transferring pulse messages between remote-controlled modules in an automotive vehicle includes a single wire bus coupled to each of the modules for transferring the pulse messages between each of the modules. A receiver circuit associated with at least one of the modules and coupled to the bus provides a communication current to the bus. A transmitter circuit associated with at least one of the modules and also coupled to the bus transmits the pulse messages utilizing the communication current. The receiver circuit, thus, becomes active and accepts the pulse messages being transmitted by the transmitter circuit upon detecting the communication current being drawn from the receiver circuit.
