Claim Text:
1. A tire condition sensing apparatus comprising: a tire-based acceleration sensor for sensing two relative rotational positions of an associated tire relative to the earth's horizon as the tire rotates and providing first and second acceleration signals indicative of sensed acceleration; transmitter for transmitting signals from the tire including a tire identification, tire condition information, and a processing time delay value in response to each of said first and second acceleration signals, wherein the processing time delay represents the time delay in processing the first and second acceleration signals during tire rotation; a vehicle-based sensor for monitoring tire rotation relative to the vehicle's chassis and providing a signal indicative of said tire rotation; and a controller for monitoring the transmitted tire identification signal, the processing time delay value, and the signal from the vehicle-based sensor and associating tire identification with a tire location in response.
