1. A communication system for a wheel assembly comprising:
- a wheel hub rotationally mounted to a hub shaft;
a controller;
a power source;
a rotationally fixed primary coil mounted to said hub shaft about an axis, said primary coil powered by said power source and in communication with said controller;
a secondary coil mounted for rotation about said axis, said secondary coil mounted to said wheel hub along the axis, said secondary coil and said primary coil mounted in an at least partially telescoped relationship; and
a sensor in communication with said secondary coil.

Abstract
A wheel sensor communication system (10) includes a primary coil (30) and a secondary coil (32), which operate as an electromagnetic transformer which is uncoupled mechanically but coupled electrically through a vehicle wheel assembly rotational interface. The electromagnetic transformer provides for the transfer of energy and data from a sensor (18) to a controller (14).

12. A method of communicating through a rotational interface comprising the steps of:
-
(1) electrically coupling a rotationally fixed primary coil about an axis with a secondary coil mounted for rotation about the axis, the secondary coil and the primary coil mounted in an at least partially telescoped relationship; (2) powering the primary coil; (3) connecting a sensor to the secondary coil; (4) communicating data from the sensor to a controller through the electrical coupling; and (5) triggering an alarm in response to a decoupling of the electrical coupling of said step (1). - View Dependent Claims (13, 14, 15, 16, 17)
