  • Patent number: 7453350
    Abstract: A system for monitoring conditions within a tire includes a sensor assemblies (14). The sensor assemblies (14) emit a transmission (26) containing information indicative of conditions within a tire to a receiver (16). The transmission (26) from the sensor assemblies (14) includes an amplitude shift key wake up portion and various data packet portions. The data packet portions are separated by a variable interval to prevent collisions of transmissions at the receiver.

  • Patent number: 7436289
    Abstract: A remote signaling receiver system includes a receiver that operates in two different modes of demodulation to accommodate different types of signals from different types of transmitting devices. A first demodulator, preferably an ASK demodulator, is adapted to process signals from a signal transmitter that generates a first type of signal. A second demodulator, preferably one that is not sensitive to amplitude modulation such as a FSK demodulator, is adapted to process signals received from at least one other type of device, which provides a second type of signal. A system designed according to this invention is particularly useful as a remote keyless entry system for a vehicle where one or more sensors are provided on the vehicle to provide an indication of a chosen condition of one or more of the vehicle components.

  • Publication number: 20080122594
    Abstract: A method of controlling fleet vehicles includes the steps of identifying transmitter signals from a select group and an entire group to allow selective operation of certain specific vehicle functions. The method also includes the step of reprogramming a secret key and storing the previous secret key such that transmitters that have not already been programmed can be programmed if they include the old secret key.

  • Publication number: 20080106367
    Abstract: A passive entry and start system transmits a neutral signal over all the antennas except for that antenna that is proximate an area in which transmission to an identification device is desired. Accordingly, the area of a vehicle and those physical features that are proximate and associated with the area is isolated to prevent undesired operation of other vehicle mechanisms.

  • Patent number: 7173520
    Abstract: To eliminate any mis-learning of a sensor code in a factory environment due to adjacent vehicles, a vehicle ID is sent to a sensor transmitter by an initiation signal. When the sensor transmitter transmits its sensor identification signal to the vehicle control in a “learn” mode, the vehicle ID received in the initiation signal is carried with a combined signal. The vehicle control receives the combined signal, and if the received vehicle identification code in the signal matches an expected vehicle identification code, then the control learns the sensor identification. If the expected vehicle identification code does not match the received vehicle identification code, then the control may ignore the particular sensor identification code. This invention thus eliminates any tendency to have an adjacent vehicle inadvertently “teach” its sensor IDs to the control associated with the adjacent vehicle.
