Monitoring device and tire combination
First Claim
1. A monitoring device and patch combination used to monitor the conditions of a pneumatic tire having an innerliner, the combination comprising:
- a monitoring device having at least one sensor and an antenna electrically connected to the monitoring device;
the antenna adapted to transmit signals from the monitoring device and receive signals transmitted to the monitoring device;
the sensor being adapted to sense at least one engineering condition of the pneumatic tire;
a patch;
the entire antenna being carried by the patch, the patch adapted to mount on the innerliner of the tire; and
the antenna being in electrical communication with the monitoring assembly through close proximity electromagnetic coupling.

Abstract
The invention provides a monitoring device and tire combination wherein an antenna is mounted to the tire in a location spaced from the monitoring device. In one embodiment, the antenna may be mounted to the tire sidewall outside the body cords of the tire. The antenna may be mounted on the outer surface of the sidewall or embedded within the body of the sidewall. The antenna is connected to the monitoring device with a connector. The connector may be electrically coupled to the monitoring device or may be connected to the monitoring device with a plug and socket connection. When the antenna is outside the body cord, the connector may extend from the antenna through the bead filler, over the top of the turn up, or under the bead ring.
