1. A system for monitoring a status of a parameter of a tire for a vehicle, the system comprising:
- a sensor, disposed within the tire, for generating a signal indicative of the parameter of the tire independently of magnitude of the parameter;
a programmable processor, in electrical communication with the sensor for determining status of the tire parameter by comparing the tire parameter to a selected threshold;
a transmitter, in electrical communication with the processor for transmitting a status signal indicative of the status of the tire parameter along a first communications link;
a monitor, in communication with the first communications link, for monitoring the status of the tire parameter;
a communication unit in electrical communication with the processor having a first receiver for receiving a processor control command; and
a remote controller, positionable for communication with the communication unit via a second communications link, for initiating the processor control command.

Abstract
The present invention relates to a method and system for monitoring a parameter of a vehicle tire. In one embodiment, a detector unit disposed within the tire communicates with a central receiver unit over an electromagnetic path comprising one or more conductive components of the vehicle. Other embodiments of the invention include additional communications links for receiving information from and controlling the detector unit and the receiver.
