System for remote tire pressure monitoring with low frequency initiation antenna
First Claim
1. A system for remote monitoring of tire pressure in a vehicle having a plurality of tires, each tire having a wheel well associated therewith, each wheel well having a surface, the system comprising:
- a tire monitor for mounting in one of the plurality of tires, the monitor comprising a transmitter for transmitting a signal representative of a sensed tire pressure, and a receiver for receiving an initiation signal;
an initiator for mounting on-board the vehicle and to be associated with the one of the plurality of tires, the initiator for use in generating a low frequency initiation signal for receipt by the receiver to cause the transmitter to transmit a tire pressure signal; and
an antenna in communication with the initiator for use in transmitting the low frequency initiation signal, the antenna comprising a multi-turn loop on the surface of the wheel well associated with the one of the plurality of tires such that the low frequency initiation signal transmitted by the antenna is received by the receiver for any tire position.

Abstract
A system for remote monitoring of tire pressure in a vehicle having multiple tires, where each tire has an associated wheel well. The system includes a tire monitor mounted in one of the tires that includes a transmitter for transmitting a signal representative of a sensed tire pressure, and a receiver for receiving an initiation signal. An initiator mounted on-board the vehicle associated with the tire is for use in generating a low frequency initiation signal for receipt by the receiver to cause the transmitter to transmit a tire pressure signal. An antenna in communication with the initiator transmits the low frequency initiation signal. The antenna includes a multi-turn loop on a surface of the wheel well associated with the tire such that the low frequency initiation signal transmitted by the antenna is received by the receiver for any tire position.
