  • Patent number: 10996329
    Abstract: In a distance estimating system, a first terminal transmits a response request signal and successively transmits impulse signals as synchronization signals, and a second terminal receives the response request signal, generates response data based on the response request signal, shifts a bit, which is a transmission target in a bit string as the response data, by one toward a rear side from a leading bit to a trailing bit each time the synchronization signal is received, transmits the impulse signal in a case where a value of a bit that is a transmission target at a time of reception of the synchronization signal is a predetermined value. The first terminal further measures a round-trip time, specifies a flight time of the impulse signal, and estimates a distance to the second terminal based on the flight time and a propagation velocity of the impulse signal.

  • Publication number: 20190184774
    Abstract: A sensor transceiver transitions into a first state that is capable of receiving RF waves intermittently. Upon starting to receive a burst signal on RF waves from a vehicle-body system under the first state, the sensor transceiver transitions into a second state that is capable of receiving RF waves continuously. Upon receiving a request signal on RF waves from the vehicle-body system under the second state, the sensor transceiver transmits data on tire pressure to the vehicle-body system.

  • Publication number: 20190176544
    Abstract: A sensor transceiver is kept in a state capable of receiving LF waves. Upon receiving LF waves indicating a start command from the vehicle-body system, the sensor transceiver is caused to be in a state capable of receiving RF waves accordingly. Upon receiving an instruction command from the vehicle-body system under the state capable of receiving RF waves, the sensor transceiver notifies the vehicle-body system of data on tire pressure.

  • Patent number: 9966952
    Abstract: A switch apparatus has a pressing section that is formed of a rubber-like elastic material and has a pressing region that is pressed in a predetermined pressing direction; and a capacitance sensor for detecting the pressing of the pressing region on the basis of capacitance. The capacitance sensor is positioned apart from the pressing section in the pressing direction, and is configured so that when the pressing region is not being pressed, a space (clearance) is maintained between the part (the lowermost surface of a protruding section of the pressing section on the side towards the capacitance sensor corresponding to the pressing region and another member (base housing disposed in the vicinity of the pressing region along the pressing direction, the space (clearance) allowing the part on the side towards the capacitance sensor to move in the pressing direction.

  • Patent number: 9776461
    Abstract: In a tire inflation pressure detection device, a receiver functions such that, when an ignition switch is on, power is generated by a power supply controller to set the power supply state of the receiver to one in which frame reception is enabled to detect the inflation pressure of a tire, and such that, when the IG is off, in each predetermined intermittent cycle power is generated by the power supply controller to set the power supply state of the receiver to one in which frame reception is enabled to detect the inflation pressure of the tire. A transmitter determines whether a decrease in tire inflation pressure occurs, and when the decrease occurs, the transmitter transmits frames more frequently than before the occurrence of the decrease in tire inflation pressure at a shorter frame transmission time interval than a regular transmission cycle during a high-frequency transmission period.
