  • Patent number: 7131323
    Abstract: A tire inflation pressure sensing apparatus according to the invention includes a first pressure sensor, a first transmitter, a second pressure sensor, a second transmitter, and a receiver. The first pressure sensor and first transmitter are provided on a running wheel of a vehicle. The first transmitter works to send out a pressure signal generated by the first pressure sensor upon being triggered by a trigger signal. The second pressure sensor and second transmitter are provided on a spare wheel of the vehicle. The second transmitter works to send out a pressure signal generated by the second pressure sensor upon being triggered by the trigger signal. The receiver is provided on the body of the vehicle and works to send out the trigger signal and identify whether a pressure signal received thereby is sent out from the first transmitter or the second transmitter based on a RSSI signal generated therefor.
