An apparatus is provided for auto-locating positions of a plurality of wireless sensors on a vehicle. The apparatus comprises a receiving unit for receiving signals from the plurality of wireless sensors. The apparatus further comprises a processing unit arranged to calculate a probability value for each one of the plurality of wireless sensors based upon signals that have accumulated over a period of time to provide a table of probability values. Each probability value contained in the table during a calculation cycle of the processing unit is indicative of likelihood of one of the plurality of wireless sensors being located at a corresponding one of a plurality of positions on the vehicle. Each one of the plurality of wireless sensors is associated with the position having the highest probability value during the calculation cycle.

Method for auto-locating positions of a plurality of wireless sensors on a vehicle and an apparatus therefor

Various examples of a transmitting device with an antenna are disclosed. In one example, a transmitting device comprises a planar circuit board; a sensor mounted on the planar circuit board; a transmitter mounted on the planar circuit board and in communication with the sensor, the transmitter configured to periodically transmit signals containing a plurality of packets; and an antenna mounted on the planar circuit board and in electrical communication with the transmitter for transmitting the signals containing the plurality of packets. The antenna comprises a first end connected to the planar circuit board and a first support section; a meander line section connected to the first support section and a second support section and lying in a plane parallel with the circuit board; a second end connected to the second support section and an electrical ground.

Transmitting device with antenna

An electronic component in a vehicle tire condition monitor system includes a first antenna, a second antenna, and a processor. The first antenna is oriented at an angle with respect to the second antenna. Both of the antennas are capable of receiving RF signals transmitted from a sensor associated with a respective tire of the vehicle. The RF signals represent a condition of the respective tire. The processor receives the RF signals transmitted by the sensor from at least one of the antennas. The first and second antennas receive the condition signals from any of a plurality of the sensors associated with respective tires on the vehicle.

Diversity antenna

A vehicle electronic control unit includes a power input port, which receives electric power from a vehicle battery, and a power output port, which provides electric power to a vehicle electronic device including an antenna. The electronic device receives data transmissions from a vehicle sensor. The power output port provides substantially uninterrupted electric power from the vehicle battery to the vehicle electronic device. A communication port is electrically connected to a vehicle communication bus. The communication port receives data transmissions from the vehicle electronic device via the communication port. An electronic component, electrically connected to the communication port, is initially in a first state when a vehicle ignition is off. The electronic component, while in a second state and while the vehicle ignition is off, receives additional data transmissions from the vehicle electronic device indicating statuses of respective vehicle sensors.

System and method for monitoring tire status

A method and apparatus for producing a circuit carrier for mounting components of a pressure sensing circuit, circuit carrier formed thereby, an apparatus for housing a pressure sensor circuit carrier to form a pressure sensing apparatus and a pressure sensing system using the pressure sensing apparatus and a coupler for coupling the pressure sensing apparatus to a pressurized system. A housing has provisions for aligning and urging a circuit carrier to sealingly position a pressure sensor adjacent an opening in a wall extending through of housing. The wall defines a pressure sensing chamber operable to cooperate with a pressure coupler having a profile that sealingly engages the wall.
