Tire pressure sensing system
First Claim
1. A tire pressure monitoring system for monitoring a pressure of at least one tire on a vehicle, said tire pressure monitoring system comprising:
- an actively powered sensor mounted relative to the at least one tire of the vehicle, said actively powered sensor operable to sense tire pressure within the at least one tire;
a receiver mounted relative to the vehicle at a location external of the tire and within proximity to said actively powered sensor, said receiver operable to generate a signal indicative of the tire pressure sensed by said actively powered sensor;
at least one node operable to receive said signal from said receiver indicative of the pressure and operable to communicate with a tire pressure status indicator; and
said tire pressure status indicator in communication with said node to provide a tire pressure status based upon said signal generated by said receiver.

Abstract
A monitoring system for monitoring a first parameter includes an active sensor, a receiver and an indicator. The active sensor is positioned at a first location and is operable to sense the first parameter. 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 first parameter 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 is in communication with the receiver to provide the first parameter to the user. This parameter may include a tire pressure of a tire on a vehicle. The monitoring system further includes a node in communication with the receiver and in communication with the indicator to provide electrical communication between the indicator and the receiver.
