Abstract
A method and apparatus for remotely measuring the pressure and temperature of gas in a vehicle wheel. The vehicle includes a frame member and a vehicle wheel mounted for rotation relative to the frame member about a rotation axis. A transmitting circuit is mounted on the frame member. The transmitting circuit includes a transmitting coil and generates electrical energy in the transmitting coil. A receiving circuit is mounted on the vehicle wheel for movement therewith such that, as the vehicle wheel rotates relative to the frame member, the receiving circuit is inductively coupled to the transmitting circuit. The receiving circuit includes a sensor for generating a data signal corresponding to a physical characteristic of the vehicle wheel and a wireless communication circuit for receiving the electrical energy from the transmitting coil to remotely power the receiving circuit and for transferring the data signal from the receiving circuit to the transmitting circuit.
