Definitions

  • FIG 1 there are shown four sensor units 2 each coupled to a respective transmitter 4. These units are included in a unit which screws onto a tyre valve and replaces its dust cap. On a four-wheel vehicle the system would be as shown in Figure 1 with four sensor/transmitter units, one attached to the dust cap on each wheel. It can however be used on two wheel vehicles or vehicles with more than four tyres or wheels.
  • the sensors are coupled to the microprocessor which monitors the output signal from its respective sensor and, if the signal alters in such a way as to indicate that the pressure in the respective tyre has changed from the first encountered pressure by more than the predetermined amount, the processor controls the transmitter to transmit a warning signal to the data processing unit 6 which receives it by means of receiver 8.
  • This warning signal comprises an identification signal identifying the sensor.
  • the identification signal is a 16-bit coded signal which enables over 65,000 different sensor identification codes to be used. This makes the chance of a signal from a sensor with a corresponding ID on another vehicle being sent to the data processing unit 6 very remote. Previous systems such as the TireMate system included the possibility of only 14 individual settings for sensor identification codes.
