Patent number: 8393204Abstract: A tire pressure measurement system (TPMS) includes a capacitor and an integrated circuit configured to receive a supply voltage. The integrated circuit includes a voltage regulator and a measurement unit. The voltage regulator is configured to be turned on and off for predetermined periods of time such that the capacitor is charged and discharged, respectively. The voltage regulator and the capacitor are connected to the measurement unit in order to selectively provide electric charge at a voltage between predetermined upper and lower limits.Type: GrantFiled: March 14, 2011Date of Patent: March 12, 2013Assignee: Infineon Technologies AGInventors: Jan Einar Nornes, Bjorn Blixhavn

Patent number: 8106758Abstract: A tire localization system for locating the position of a tire of a vehicle having five or more wheels, includes a number of tire pressure monitoring system (TPMS) wheel modules of a vehicle TPMS, each wheel module being attached to each one of the wheels or a tire thereof, respectively. Each TPMS wheel module includes a radio, frequency identification (RFID) reader. The system further includes a number of RFID tags, each RFID tag being associated with and storing wheel position information of one of the wheels, and each RFID tag being positioned externally of its associated wheel. Each of the RFID readers is arranged, upon activation, to interrogate its associated RFID tag, and the associated RFID tag is arranged, upon interrogation, to transmit its stored position information to the RFID reader for transmission by the TPMS wheel module to a central control unit. A tire localization method is also provided.Type: GrantFiled: February 14, 2011Date of Patent: January 31, 2012Assignee: Infineon Technologies AGInventors: Markus Loehndorf, Terje Kvisteroey, Bjorn Blixhavn

Patent number: 7615845Abstract: An apparatus that reduces parasitic capacitance in a MEMS device includes a dielectric layer on the surface of a silicon-on-insulator (SOI) substrate, a conductor embedded in the substrate and disposed between the dielectric layer and a buried oxide layer, and surface conductors on the dielectric layer and coupled to ends of the embedded conductor. A boundary region surrounds the embedded conductor and separates an inner region and an outer region of substrate, providing a p-n junction between the boundary region and the outer region of SOI substrate which is reverse biased to electrically isolate the inner region from the outer region of SOI substrate. An amplifier has an input connected to one end of the embedded conductor and an output connected to the inner region of the substrate. The amplifier senses a voltage at the input and produces a voltage that approximates the voltage at the output.Type: GrantFiled: June 25, 2008Date of Patent: November 10, 2009Assignee: Infineon Technologies SensoNor ASInventor: Bjørn Blixhavn
