Tire pressure sensing system
First Claim
1. A tire pressure monitoring system for monitoring a pressure of at least one tire on a trailer connected to a vehicle and providing a signal to an occupant in the vehicle, said tire pressure monitoring system comprising:
- an sensor mounted relative to the at least one tire on the trailer, said sensor operable to sense tire pressure within the at least one tire; and
a receiver indicator module mounted to the trailer at a location external of the tire and within proximity to said sensor, said receiver having a receiver indicator module and an indicator, said indicator module operable to generate a signal indicative of the tire pressure sensed by said sensor, said indicator being remote of the vehicle.

Abstract
A monitoring system for monitoring pressure in a tire of a trailer includes an active sensor, a receiver and an indicator. The active sensor is positioned at a first location and is operable to sense the pressure. The receiver is positioned at a second location remote from the first location and within proximity to the sensor. The receiver is operable to generate a signal indicative of the pressure and includes an inductor, and an amplifier having a feedback path. The inductor is positioned relative to the receiver to create an electromagnetically coupling between the inductors such that feedback from the coupling is one of either a substantially zero feedback and a negative feedback. The indicator outside of a vehicle is in communication with the receiver to provide a warning of a low pressure to the user.

12. A tire monitoring system for monitoring a physical parameter of at least one tire on a trailer connected to a vehicle having a reflective surface positioned to allow an occupant to view a portion of the trailer, said tire monitoring system comprising:
-
a sensor mounted relative to the at least one tire of the trailer, said sensor operable to sense the physical parameter within the at least one tire;
a receiver mounted to the trailer and at a location external of the tire and within proximity to said sensor, said receiver operable to generate a first signal indicative of the physical parameter sensed by said sensor; and
a tire status indicator in communication with said receiver, said tire status indicator being remote from the vehicle and viewable by the occupant. - View Dependent Claims (13, 14, 15)
