Patent number: 7145507Abstract: A vehicle locating system for directing a user to a remotely-located vehicle comprises a vehicle-mounted location unit and a personal fob. The vehicle-mounted location unit includes a first global positioning receiver for receiving satellite location signals which operates at a duty cycle sufficient to maintain predetermined aiding data. The vehicle-mounted location unit processes vehicle location data and further includes a first local data transceiver for transmitting the predetermined aiding data. The portable fob includes a second global positioning receiver for receiving the satellite location signals, wherein the second global positioning receiver operates substantially only when the user initiates a request for directions to the vehicle. The portable fob further includes a second local data transceiver for receiving the predetermined aiding data from the first local data transceiver. The portable fob processes fob location data in response to the predetermined aiding data.Type: GrantFiled: December 16, 2003Date of Patent: December 5, 2006Assignee: Lear CorporationInventors: Yi Luo, Oingfeng Tang, Ronald O. King, Thomas J. Lemense

Patent number: 6941801Abstract: A method is provided for replacing at least one tire of a vehicle on a first wheel in a first wheel position, the vehicle having a tire pressure monitoring system with a first sensor unit having a first ID code mounted to the first wheel. The first sensor unit is interrogated. Either a nominal result or a faulted result of the interrogation is detected. The at least one tire is removed from the first wheel. If the nominal result is detected during the interrogating step, then the first sensor unit is re-interrogated. Either a nominal result or a faulted result of the re-interrogation is detected. If either of the interrogation or the re-interrogation provide a faulted result then the first ID code is cloned into a replacement sensor unit and then the replacement sensor unit is swapped for the first sensor unit on the first wheel. A new tire is installed onto the first wheel. The first wheel is installed onto the vehicle in the first wheel position.Type: GrantFiled: December 19, 2003Date of Patent: September 13, 2005Assignee: Lear CorporationInventors: Thomas J. Lemense, John S. Nantz, Kenneth J. Cunningham, Qingfeng Tang

Patent number: 6931920Abstract: A tire monitoring system for a vehicle. The tire monitoring system includes a sensor assembly mountable on a wheel and has a first sensor for detecting a tire parameter and a second sensor for detecting proximity of the sensor assembly to the wheel. The sensor assembly is detached from the wheel when the second sensor is not proximate to the wheel.Type: GrantFiled: July 16, 2003Date of Patent: August 23, 2005Assignee: Lear CorporationInventors: Calvin Modawell, Thomas J. LeMense, Keith Walker

Patent number: 6218632Abstract: The present invention is directed to a weight sensing apparatus (10) for a vehicle seat (22). The weight sensing apparatus (10) includes a differential capacitor (150) including a first capacitor (152) and a second capacitor (176). The first capacitor (152) includes first and second opposed plate assemblies (154 and 156). The second capacitor (179) includes a third plate assembly (180) and the second plate assembly (156). Each plate assembly (154, 156, and 180) includes a plurality of electrically conductive elongated members that extend in an axial direction. The second plate assembly (156) is interposed between the first and third plate assemblies (154 and 180) and is movable in an axial direction relative to the first and third plate assemblies (154 and 180) in response to a load being applied to a vehicle seat. A source of alternating current supplies electrical energy to the differential capacitor (150) and an output circuit is electrically connected with the differential capacitor (150).Type: GrantFiled: June 30, 2000Date of Patent: April 17, 2001Assignee: TRW Inc.Inventors: Michael C.

Patent number: 5958081Abstract: An energy efficient remote control protocol uses a start bit which has a variable length which corresponds to the parity of the transmitted symbol, a guard time which is fixed at a predetermined length, and a data transmission time which corresponds to the data to be transmitted. The data to be transmitted is transmitted as a logic low, thus improving the energy efficiency of the system. During the transmission of a code, only one stop bit is used at the end of the transmission. The guard time and parity check are used to verify proper transmission.Type: GrantFiled: October 11, 1995Date of Patent: September 28, 1999Assignee: Ford Motor CompanyInventors: Thomas J. Lemense, Tejas B. Desai

Patent number: 5568120Abstract: A remote controlled anti-theft system for transportation vehicles allows the user to easily determine at will if a faulty door position sensor or an open door will inhibit proper operation of the anti-theft system by pressing the lock button on the remote transmitter in a predetermined sequence. A first lock code from the remote transmitter initiates a locking and arming sequence of the anti-theft system. A second lock code received within a predetermined time of the first lock code causes an audible verification to be produced identifying whether the anti-theft system is successfully arming or whether a door ajar or faulty door sensor is preventing the anti-theft system from arming.Type: GrantFiled: December 6, 1994Date of Patent: October 22, 1996Assignee: Ford Motor CompanyInventors: Thomas J. LeMense, David R. Tengler
