Patent ID: 6963274

Claim:
Transmitters of a tire condition monitoring apparatus that monitors condition of vehicle tires, wherein each transmitter is provided in one of the tires, each transmitter comprising: at least one measuring device for measuring a condition of the corresponding tire; a transmitting system on each measuring device for periodically transmitting data representing the measured tire condition, wherein each of said transmitting systems periodically transmits said data during a same time interval; a detecting device for detecting moving of the vehicle; and a delay mechanism for computing a delay time, the delay time being a period from when the detecting device detects moving of the vehicle to when the data representing the condition of the corresponding tire is transmitted, wherein the computed delay time is always different from one transmitter to each of the other transmitters, and wherein the transmitting systems of all the transmitters first transmit the data after the respective delay times, wherein said delay times are different from each other, and wherein said delay times have elapsed from when the vehicle starts moving, and then the transmitters periodically transmit the data at the same time intervals.
