Tire monitoring apparatus and method
First Claim
1. A method of measuring and monitoring a plurality of remotely located devices at a central location, the method comprising the steps of:
- (a) providing a plurality of measurement and transmission circuits, each circuit;
(i) developing a signal in response to a respective physical quantity, property or condition;
(ii) sampling said signal to produce an instantaneous signal value;
(iii) assigning a first code to said instantaneous signal value;
(iv) transmitting a transmission including the code and an identifier unique to the circuit;
(b) receiving a received transmission from each of said measurement and transmission circuits;
(c) extracting and storing said identifier and said code from said received transmission;
(d) determining which identifier has been received; and
(d) displaying a representation of said received code while providing an identification of the received code.

Abstract
A method and apparatus for measuring a physical quantity, property or condition and for transmitting a code representing the measured physical quantity, property or condition. The method includes the steps of developing a first signal in response to a physical quantity, property or condition, sampling the first signal to produce an instantaneous first signal value, assigning a first code to the instantaneous first signal value, and transmitting the first code for reception by a receiver. The method and apparatus are explained in connection with a vehicle tire monitoring apparatus wherein plurality of tire units measure tire pressures and temperatures and transmit values representing pressure and temperature to a central receiver located in a cab portion of the vehicle.
