TIRE HAVING RADIO FREQUENCY IDENTIFICATION DEVICE FOR MONITORING STRUCTURAL HEALTH
First Claim
1. A tire structural health monitoring assembly comprising:
- a tire having a plurality of components including;
a pair of annular beads,a body ply extending between the annular beads,a circumferential belt disposed above the body ply and extending axially across a portion of the body ply,a circumferential tread disposed above the circumferential belt,a pair of shoulders extending from opposite sides of the circumferential tread, anda pair of sidewalls, each sidewall extending between one of the annular beads and one of the shoulders;
at least one radio frequency identification (RFID) tag disposed between two components of the tire, wherein the RFID tag is in contact with each of the two components; and
an RFID reader configured to receive a response signal from the RFID tag,wherein, when no air is present in a region surrounding the RFID tag, the RFID reader receives a response signal at a first frequency and a first power level , andwherein, when air is present in the region surrounding the RFID tag, the RFID reader receives a response signal at the first frequency and a second power level different from the first power level; and
a processor configured to identify the power level of a response signal received by the RFID reader at the first frequency, and further configured to transmit a notification when the power level of the response signal is outside a pre-determined range.

Abstract
A tire includes a plurality of tire components defining a plurality of layers. A radio frequency identification (RFID) tag is disposed between at least two of the plurality of layers. The RFID tag is in contact with each of the at least two layers and is configured to transmit a response signal in response to receiving a request signal. When no air is in a region surrounding the RFID tag, a first response signal is emitted from the tire at a first frequency and first power. However, when air is in the region surrounding the RFID tag, a second response signal is emitted from the tire at the first frequency and a second power different from the first power.
