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 a first inductor, a second inductor and an amplifier having a feedback path. The first inductor and the second inductor are positioned relative to one another 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 transducer in communication with the receiver and in acoustic communication with the indicator to provide electrical communication between the indicator and the receiver without direct connected wiring.
