First Claim
1. A transponder for sensing a condition relating to a tire, comprising:
- a tire condition sensor adapted to sense a condition relating to the tire; and
a control system comprising at least two operating modes, said control system communicatively connected to said tire condition sensor and transmitting information from said tire condition sensor to a remote location in one of said at least two operating modes depending on how the remote location interrogates the control system.

Abstract
A tire sensor that communicates to a remote interrogator in one of two modes depending on the nature of the interrogation. The interrogator may be distributed throughout a vehicle if needed for design options. Further, the interrogator only interrogates the transponder when the interrogator has reason to believe that the transponder is in range of the interrogator. The interrogator and transponder may be configured to operate in different modes for communication during operation of the tire on a vehicle and during non-operation. The transponder may communicate tire condition information to the interrogator concerning environmental or other information sensed about the tire.
