METHOD AND APPARATUS FOR TRANSMITTING STORED DATA AND ENGINEERING CONDITIONS OF A TIRE TO A REMOTE LOCATION

摘要

A method for monitoring various engineering conditions of a pneumatic tire such as temperature, pressure, tire rotation and other operating conditions of t he tire. A tire tag is mounted on the interior of the tire within the pressurizable cavity and contains the stored data and sensors for detecting certain conditions within the cavity. A separate transponding device is mounted on the tire rim. The tire tag contains a battery, an antenna and stored data pertaining to the tire. The transponding device uses electronic circuitry which collects data from the tire tag. The tire tag is actuated by transmitted radio frequency waves from the transpond ing device, which data is retransmitted by the transponding device to the remote location by an antenna which extends from the transponding device through the ri m to a location externally of the tire.
