Tire condition sensor communication with unique sampling on vehicle-side diversity antenna array
First Claim
1. A tire condition communication system for a vehicle, said system comprising:
- sensor means, associated with a tire, for sensing at least one tire condition;
transmitter means, associated with the tire and operatively connected to said sensor means, for transmitting a signal that has a data rate and that indicates the sensed tire condition; and
receiver means, associated with the vehicle, for receiving the signal, said receiver means including a plurality of antennas, each for receiving the transmitted signal, and means for switching among the plurality of antennas at a rate that is quicker than the data rate of the transmitted signal.

Abstract
A system (10) and associated method for tire condition communication for a vehicle (12). The system (10) includes a sensor (18), associated with a tire (14), to sense at least one tire condition. Transmitter components (22, 24 and 30), associated with the tire (14) and operatively connected to the sensor (18), provide for transmission of a signal (32) that has a data rate and that indicates the sensed tire condition. A receiver unit (40), associated with the vehicle (12), receives the signal (32). The receiver unit (40) includes a plurality of antennas (42A-42N), each for receiving the transmitted signal (32), and a switching device (46) among the plurality of antennas at a rate that is quicker than the data rate of the transmitted signal (32).

8. A tire condition communication system for a vehicle, said system comprising:
-
a tire condition sensor and a transmitter unit associated with a tire, a transmitted signal from said unit has a data rate and indicates a sensed tire condition; and
a receiver unit associated with the vehicle, said receiver unit includes a plurality of transmitted signal receiving antennas, said receiver unit includes a plurality of switches, with each switch being interposed between a respective one of said antennas and another portion of said receiver unit, and said receiver unit including a switch-controlling controller that controls said switches to sequentially connect one antenna at a time to said other portion of said receiver at a rate that is quicker than the data rate of the transmitted signal.
