Abstract: In a wheel identifying apparatus, first and second devices respectively transmit first and second trigger signals. The first device is mounted on the body of a vehicle closer to the front axle than the rear axle and closer to one of the front wheels than the other; it has the same height as the front axle and an orientation angle in a range of 0 to 90°. The second device is mounted on the vehicle body closer to the rear axle than the front axle and closer to one of the rear wheels than the other; it has the same height as the rear axle and an orientation angle in a range of 0 to 90°. Consequently, the first trigger signal can be reliably received by transceivers on the front wheels, and the second trigger signal can be reliably received by transceivers on the rear wheels.

Abstract: A tire inflation pressure sensing apparatus according to the present invention includes a transmitter, a receiver, and a command signal receiver. The transmitter is provided on a wheel of a vehicle and includes a pressure sensor configured to sense the inflation pressure of a tire on the wheel and generate a pressure signal indicative of the sensed inflation pressure. The receiver is provided on the body of the vehicle and works to receive the pressure signal and determine the inflation pressure of the tire based on the pressure signal. The command signal receiver is operatively connected to the transmitter and works to receive command signals that indicate instructions for the transmitter. The command signal receiver has a variable receiver sensitivity so as to prevent the command signal receiver and transmitter from being activated by noises while ensuring reliable activation of the command signal receiver and transmitter by “true” command signals.

Abstract: A batteryless tire inflation pressure detecting apparatus includes, on the body of a vehicle, antennas and a transmitter transmitting radio waves through the antennas. The apparatus also includes, on each wheel of the vehicle, a pressure sensor sensing the pressure of a tire, a transceiver, and a charging unit powering the pressure sensor and the transceiver. The charging unit is charged with electric power induced by a corresponding one of the radio waves received by the transceiver. The apparatus further includes, on the body of the vehicle, a receiver receiving pressure signals transmitted by the transceivers, a pressure determiner determining the pressures of the tires based on the pressure signals, and a controller. To minimize influence of the radio waves on neighboring devices, the controller controls the transmitter so that least two of the radio waves are transmitted at different times, or at the same with a phase difference therebetween.

Abstract: A receiver includes an antenna, an impedance-matching circuit, a receive circuit, a control circuit, a digital-to-analog (D/A) converter, a mode switch, and an EEPROM. The impedance-matching circuit includes a variable-capacitance diode. The control circuit determines an operation mode set by the mode switch. It controls the D/A converter to produce different levels of the reverse bias voltage when the operation mode is set to an adjustment mode. It determines strength of receive signals based on receive signal strength indication (RSSI) signals indicating strength of the receive signals. It determines a maximum value of the RSSI signals based on the results of the determination, and stores D/A input data corresponding to the maximum value in the EEPROM as the adjustment data. It loads the adjustment data from the EEPROM and controls the D/A converter to produce a reverse bias voltage based on the adjustment data. The D/A converter applies the voltage to the variable-capacitance diode.
