Patent ID: 7148793

Claim:
A tire parameter sensing system for a vehicle having a plurality of tires, the tire parameter sensing system comprising: a plurality of tire-based parameter sensing units, each tire-based unit having an associated tire and being configured to receive initiation signals and, in response thereto, to transmit response signals; a vehicle-based unit for receiving response signals from the tire-based units and for transmitting the initiation signals to the tire-based units; and a plurality of signal masking devices coupled to the vehicle-based unit, each of the signal masking devices having an associated tire location in which a tire-based unit is located, each signal masking device being actuatable for masking the initiation signals near its associated tire location, actuation of a masking device blocking receipt of the initiation signal by its associated tire-based unit, the vehicle-based unit controlling the signal masking devices so as to control the associated tire location from which a tire-based unit responds to the initiation signals.
