摘要： 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.

摘要： A tire condition detecting system has transmitters and a receiver. The transmitter is installed in a plurality of wheels and the receiver is installed in a chassis of a vehicle. The receiver has a controller which determines transmission timings in which a transmitting/receiving unit transmits the electrical wave for electrical charging to the transmitters. Moreover the controller detects an electrical wave from a nearby vehicle at the transmission timing. If the detected wave from the nearby vehicle is stronger, the controller waits for a predetermined period before making the transmitting/receiving unit transmit the electrical wave.

摘要： Transceiver ID information associated with a subject vehicle is accurately registered even when another vehicle having transceivers is nearby. During ID registration, a degree of a variance among received strength data elements is obtained in relation to a plurality of transceivers each having ID information associated therewith. ID information associated with data elements having a small degree of a variance is recognized as ID information of a transceiver attached to the subject vehicle. Therefore, ID information associated with transceivers attached to the subject vehicle can be reliably discriminated from ID information associated with transceivers attached to another vehicle.

摘要： 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.
