Abstract

A smart tag assembly is designed for mounting on an object to be tracked. The smart tag assembly comprises a multiple layer RFID laminate adapted for electronically storing and processing data, and wireless communicating data when interrogated by an RFID reader. The laminate comprises an RFID inlay including a microchip and antenna formed with a substrate, and laminated between an outside label cover and backing. A low-profile tag carrier defines a recessed pocket designed for receiving and holding the RFID laminate, and has a generally concave outside surface adapted for residing against a generally convex surface of the object to be tracked.

Claims

1. A smart tag assembly designed for mounting on a side wall of a vehicle tire, said smart tag assembly comprising:

a multiple layer RFID laminate adapted for electronically storing and processing data and wireless communicating data when interrogated by an RFID reader, said laminate comprising an RFID inlay including a microchip and antenna formed with a substrate and laminated between an outside label cover and backing; and

a low-profile tag carrier defining a recessed pocket designed for receiving and holding said RFID laminate, and having a generally concave outside surface adapted for residing against a generally convex surface of the tire side wall; and

tag-orienting indicia located on an exposed surface of said label cover and applicable for orienting said smart tag assembly on the vehicle tire, such that fatigue at a connection of said microchip and antenna is reduced as the side wall of the vehicle tire flexes during each revolution.

2. The smart tag assembly according to claim 1, wherein said tag carrier is constructed of a generally flexible elastomeric material.

3. The smart tag assembly according to claim 2, wherein said elastomeric material comprises a natural rubber.

4. The smart tag assembly according to claim 3, wherein said natural rubber has a hardness of between about 50-80 durometer.

5. The smart tag assembly according to claim 1, wherein said tag carrier is substantially disk shaped.

6. The smart tag assembly according to claim 5, wherein said tag carrier comprises an inwardly extending peripheral lip surrounding said recessed pocket and adapted for retaining and protecting said RFID laminate.

7. The smart tag assembly according to claim 6, wherein said peripheral lip comprises a plurality of equally-spaced arcuate sections defining respective chamfered top edges.

8. The smart tag assembly according to claim 5, wherein said tag carrier comprises a continuous rounded outside peripheral edge.

9. The smart tag assembly according to claim 5, wherein said tag carrier has a height dimension less than 0.25 inches and an outside diameter less than 2.0 inches.

10. The smart tag assembly according to claim 1, wherein a bottom surface of tag carrier is textured to a depth ranging from about 0.00100 and 0.00600.

11. The smart tag assembly according to claim 1, wherein an inside surface of said recessed pocket is textured to a depth ranging from about 0.00100 and 0.00600.

12. The smart tag assembly according to claim 1, wherein an exposed surface of said label cover comprises at least one part identification code.

13. The smart tag assembly according to claim 1, and comprising a spacer attached to a bottom surface of said tag carrier, and adapted for spacing said RFID laminate from the object.

14. The smart tag assembly according to claim 1, wherein said RFID laminate further comprises at least one spacer ring surrounding said RFID inlay and substrate, and laminated between said outside label cover and backing.

15. In combination with a pneumatic vehicle tire adapted for mounting on a wheel rim and hub, a smart tag assembly affixed to a side wall of said vehicle tire and comprising:

a multiple layer RFID laminate adapted for electronically storing and processing data and wireless communicating data when interrogated by an RFID reader, said laminate comprising an RFID inlay including a microchip and antenna formed with a substrate and laminated between an outside label cover and backing; and

a low-profile tag carrier defining a recessed pocket designed for receiving and holding said RFID laminate, and having a generally concave outside surface adapted for residing against a generally convex surface of the tire side wall; and

tag-orienting indicia located on an exposed surface of said label cover and applicable for orienting said smart tag assembly on the vehicle tire, such that fatigue at a connection of said microchip and antenna is reduced as the side wall of the vehicle tire flexes during each revolution.

16. The combination according to claim 15, wherein said tag carrier is substantially disk shaped.

17. The combination according to claim 16, wherein said tag carrier comprises an inwardly extending peripheral lip surrounding said recessed pocket and adapted for retaining and protecting said RFID laminate.

18. The combination assembly according to claim 17, wherein said peripheral lip comprises a plurality of equally-spaced arcuate sections defining respective chamfered top edges.
