Abstract:
1. A system comprising: a plurality of first sensors associated with a plurality of first tires, each of said plurality of first sensors adapted to generate first wireless signals indicative of a relative rotational direction of a corresponding one of said plurality of first tires; a plurality of second sensors associated with a plurality of second tires, each of said plurality of second sensors adapted to generate second wireless signals indicative of a relative rotational direction of a corresponding one of said plurality of second tires; a transmitter adapted to transmit a location signal that is receivable by said plurality of first sensors and said plurality of second sensors, wherein said first wireless signals include indicia of first frequencies at which said plurality of first sensors receive said location signal during a predetermined time period, and wherein said second wireless signals include indicia of second frequencies at which said plurality of second sensors receive said location signal during said predetermined time period; and a receiver module receiving said first and second wireless signals and operable to determine a location of each of said plurality of first and second tires based on said first and second wireless signals.
