Abstract
A method and apparatus for remotely measuring the pressure and temperature of the gas in a vehicle wheel The vehicle includes a frame member, a vehicle wheel mounted for rotation relative to the frame member about a rotation axis, and a modulator mounted on the vehicle wheel for movement therewith The modulator generates a carrier signal including a first component encoding a plurality of consecutive data signals corresponding to a physical characteristic of the vehicle wheel, and the carrier signal including a second component identifying a portion of the respective one of the data signals
Claims23
A vehicle comprising:
- a frame member;
- a vehicle wheel mounted for rotation relative to said frame member about a rotation axis;
- and
- a modulator mounted on said vehicle wheel for movement therewith, such that said modulator generates a carrier signal including a first component encoding a plurality of consecutive data signals corresponding to a physical characteristic of said vehicle wheel, and said carrier signal including a second component identifying a portion of said respective one of said data signals.
An apparatus for mounting on a vehicle, the vehicle having a frame member and a vehicle wheel mounted for rotation relative to the frame member, said apparatus detecting a physical characteristic of the rotating vehicle wheel and said apparatus comprising:
- a transmitting circuit adapted to be mounted on the frame members said transmitting circuit including a transmitting coil and said transmitting circuit generating electrical energy in said transmitting coil;
- and
- a receiving circuit adapted to be mounted on the vehicle wheel, said receiving circuit including a sensor for measuring a physical characteristic of said vehicle wheel and modulating means connected to said sensor for generating a carrier signal including a first component encoding a plurality of consecutive data signals corresponding to the physical characteristic of the vehicle wheel, and a second component identifying the beginning of respective ones of said data signals.
A method of detecting, on a vehicle having a frame member and a wheel mounted for rotation relative to the frame members a physical characteristic of the rotating wheel said method comprising the steps of:
- (A) mounting a transmitting circuit on said frame member;
- (B) mounting a receiving circuit on said vehicle wheel so that said receiving circuit is spaced from said transmitting circuit and so that said receiving circuit rotates relative to said transmitting circuit;
- and
- (C) generating a data signal including a first component representing the physical characteristic of said vehicle wheel, and a second component identifying a portion of said first component.
A vehicle comprising:
- a frame member;
- a transceiver mounted on said frame member;
- a vehicle wheel mounted for rotation relative to said frame member about a rotation axis;
- and
- a transponder mounted on said vehicle wheel for movement therewith, said transponder having a modulator such that said modulator generates a carrier signal including a first component encoding a plurality of consecutive data signals corresponding to a physical characteristic of said vehicle wheel, and said carrier signal including a second component identifying a portion of said respective one of said data signals, wherein said transponder is inductively coupled to said transceiver.
