MONITORING OF WEARING SURFACE LAYER THICKNESS
First Claim
1. A method of wear level determination, comprising:
- distributing multiple Radio Frequency IDentification (RFID) tags within a thickness of a wearing surface layer of a tire at an X coordinate and a Y coordinate, said X coordinate being a coordinate along a rotation axis of the tire, said Y coordinate being a coordinate along a radius of the tire, said wearing surface layer of the tire being an outermost surface layer of the tire, said multiple RFID tags and said wearing surface layer adapted to be worn away as the tire is being used such that the thickness of the wearing surface layer is reduced as the tire is being used, said multiple RFID tags consisting of a first plurality of RFID tags that have not been worn away, a second plurality of RFID tags that have been worn away, and a special RFID tag that has not been worn away;
after said distributing and after the tire has been mounted on a vehicle and after the second plurality of tags has been worn away and while the first plurality of tags has not been worn away and while the special RFID tag has not been worn away, receiving data from the first plurality of RFID tags and from a table in the special RFID tag; and
determining a measure of wear of the wearing surface layer of the tire from said received data,wherein the table in the special RFID tag comprises;
an identifier of each RFID tag of the first plurality of RFID tags, the X coordinate and the Y coordinate of each RFID tag of the first plurality of RFID tags, an identifier of each RFID tag of the second plurality of RFID tags, and the X coordinate and the Y coordinate at each which each RFID tag of the second plurality of RFID tags had been disposed in the wearing surface layer before being worn away.

Abstract
A method of wear level determination and an associated product. Multiple Radio Frequency IDentification (RFID) tags are distributed within a thickness of a wearing surface layer of a tire. The multiple RFID tags include first RFID tags that have not been worn away, second RFID tags that have been worn away, and a special RFID tag that has not been worn away. A measure of wear of the wearing surface layer of the tire is determined from data received from the first RFID tags and from a table in the special RFID tag. The product includes the wearing surface layer of the tire, the multiple RFID tags, and a mechanism for determining the measure of wear of the wearing surface layer.
