SENSING AND COMMUNICATION SYSTEM AND METHOD
First Claim
1. An air spring assembly comprising:
- a first end member;
a second end member spaced a distance from said first end member and undergoing an external input;
a flexible wall secured between said first and second end members;
a transceiver supported on said first end member and broadcasting an electromagnetic wave;
a transponder supported on said second end member and receiving said electromagnetic wave; and
,a sensor supported on said second end member and in communication with said transponder, said sensor being adapted to measure the external input of said second end member and generate a corresponding sensor output signal;
said transponder receiving said sensor output signal and causing a modulation of said electromagnetic wave in relation to said sensor output signal.

Abstract
A sensing and communication system includes a transceiver broadcasting an electromagnetic wave, a transponder supported on an associated structural member at a distance from the transceiver that receives the electromagnetic wave, and a sensor adjacent the transponder and in communication therewith. The sensor being operable to sense an input acting on the associated structural member and communicate a signal corresponding to the input to the transponder. The transponder is adapted to induce a modulation of the electromagnetic wave in relation to at least one of the sensor signal and the distance between the transceiver and the transponder. A method is also disclosed.
