Patent number: 7436289Abstract: 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.Type: GrantFiled: May 26, 2006Date of Patent: October 14, 2008Assignee: Continental Automotive Systems US, Inc.Inventors: Tejas B.

Patent number: 7173520Abstract: 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.Type: GrantFiled: March 24, 2003Date of Patent: February 6, 2007Assignee: Siemens VDO Automotive CorporationInventors: Tejas B.
