DISTANCE DETERMINING SYSTEM AND METHOD
First Claim
1. A distance determining system for use with an associated fluid spring assembly, said distance indicating system comprising:
- a first transceiver operative to output a first electromagnetic wave and receive a second electromagnetic wave;
a second transceiver spaced a distance from said first transceiver and operative to receive said first electromagnetic wave and output said second electromagnetic wave;
said first transceiver including a timer operative to determine an elapsed time having a relation to said output of said first electromagnetic wave from said first transceiver and said receipt of said second electromagnetic wave at said first transceiver, said timer operative to generate an elapsed time signal having a relation to said determined elapsed time.

Abstract
A distance determining system includes a first transceiver and a second transceiver spaced a distance from the first transceiver and inductively coupled thereto. The first transceiver outputs a first electromagnetic wave. The second transceiver receives the first electromagnetic wave and outputs a second electromagnetic wave, which is received by the first transceiver. One of the first and second transceivers determines a distance therebetween based at least in part upon the elapsed time of travel of the first and second electromagnetic waves. An air spring assembly can include such a distance indicating system. A method of determining a distance is also included.
