    Abstract: A filter system that filters WCS signals received by a satellite radio antenna if the WCS signals have a high enough signal strength where they could overwhelm the satellite radio signals and prevent the satellite radio from operating. The filter system includes a coupling circuit that couples off a small portion of the signal received by the antenna and sends it to a detector that detects the signal strength of the coupled off portion of the signal. If the signal strength exceeds a predetermined threshold, the detector provides a control signal to a switch that directs the signal received by the antenna to a WCS filter to filter out the WCS signals, where the switch otherwise causes the signal received by the antenna to be sent directly to the radio.

    Abstract: A TPMS that uses a unique signature, such as RSSI signal levels and statistics or Doppler shift information, to identify the location of where the TPMS signal is being transmitted from. The TPMS includes a separate transmitter unit provided in each tire, where each transmitter unit transmits TPMS signals including an ID code identifying the tire and the pressure in the tire. The TPMS also includes a receiver unit that receives the TPMS signals from each of the transmitter units, where the receiver unit stores an average or other classification of the signature over time to identify the location of the transmitter unit for a particular ID code. The receiver unit compares the new received TPMS signals to the classified signals to identify whether the ID code indicates that the position of the tire has changed.

    Abstract translation: 使用诸如RSSI信号电平和统计或多普勒频移信息之类的唯一签名的TPMS来识别TPMS信号在何处被发送的位置。 TPMS包括在每个轮胎中提供的单独的发射器单元，其中每个发射器单元传输TPMS信号，包括识别轮胎的ID码和轮胎中的压力。 TPMS还包括接收单元，其接收来自每个发射机单元的TPMS信号，其中接收机单元存储随着时间的签名的平均或其他分类，以识别用于特定ID码的发射机单元的位置。 接收器单元将新接收到的TPMS信号与分类信号进行比较，以识别ID码是否指示轮胎的位置已经改变。
