Patent number: 8026793Abstract: Vehicle information (e.g., status information, calibratable parameters, or diagnostic data) is transmitted from a base station mounted in a vehicle to a portable RKE fob via a radio-frequency signal within a specified average field strength limit. A multi-byte vehicle message is formed and then coded into a multi-bit coded message. The multi-bit coded message is framed into a plurality of packets. The radio-frequency signal is wirelessly transmitted from the base station with a plurality of spaced packet windows having a predetermined duty cycle, each packet window including a respective one of the plurality of packets. The radio-frequency signal within each of the packet windows has a predetermined field strength greater than the average field strength limit and a substantially zero field strength between the packet windows. The predetermined duty cycle results in an actual average field strength for transmitting all of the packets not exceeding the average field strength limit.Type: GrantFiled: October 7, 2004Date of Patent: September 27, 2011Assignee: Lear CorporationInventors: Yi Luo, Riad Ghabra, Qingfeng Tang

Patent number: 7986960Abstract: A method is provided for self-aligning a transmitting frequency between a portable transceiving device and a base station transceiving device. A test signal is transmitted from one of a portable or base station transceiving devices to the other of the portable or base station transceiving devices. The test signal has a frequency that varies during the transmission. The varying of the frequency of the test signal generates a plurality of discrete signals. The other of the portable or base station transceiving devices measures a RSSI value of each discrete signal. The other of the portable or base station transceiving devices determines a discrete signal having a maximum RSSI value. At least a portion of a subsequent message from the other of the portable transceiving device or the base station transceiving device is transmitted at an optimum frequency used for the test signal identified by the test result signal.Type: GrantFiled: August 21, 2009Date of Patent: July 26, 2011Assignee: Lear CorporationInventors: Riad Ghabra, Yi Luo, Qingfeng Tang
