Abstract

A transponder carrier for embedded incorporation into a rubber article includes a bonding layer; a base layer affixed to the bonding layer, the base layer having a support surface for supporting a transponder device; and a reinforcement cap affixed to the base layer supporting surface at least partially covering the transponder device. The cap may be composed of textile cord reinforced rubber, the cap textile cords arranged in a substantially square woven configuration. A ratio of the cap to transponder device areas is within a range of 2:1 to 8:1 and the transponder device may further be coated with an adhesive to bond the transponder device to the cap and to the base layer. An antenna in a dipole antenna configuration is coupled to the transponder device in one construction.

Claims

1. A transponder carrier for embedded incorporation into a rubber article, the carrier comprising:

a. a bonding layer;

b. a base layer affixed to the bonding layer, the base layer having a support surface for supporting a transponder device;

c. a reinforcement cap affixed to the base layer supporting surface at least partially covering the transponder device.

2. A transponder carrier according to claim 1, wherein the cap is composed at least partially of textile cord reinforced rubber.

3. A transponder carrier according to claim 2, wherein the cap textile cords are in a substantially quadrilateral woven configuration.

4. A transponder carrier according to claim 3, wherein a ratio of the cap to transponder device areas is within a range of 2:

1 to 8;

1.

5. A transponder carrier according to claim 3, wherein the cap textile cords are composed at least partially of monofilament Nylon 66.

6. A transponder carrier according to claim 3, wherein the cap textile cords have a nominal linear density dTex of 470.

7. A transponder carrier according to claim 3, wherein the cap textile cords are in a substantially square woven configuration having substantially 96 ends/dm and substantially 96 picks/dm.

8. A transponder carrier according to claim 1, wherein further comprising an antenna coupled to the transponder device.

9. A transponder carrier according to claim 8, wherein the antenna is in a dipole antenna configuration and the cap at least partially covers the antenna.

10. A transponder carrier according to claim 1, wherein the base layer is composed of a productive non-reinforced rubber.

11. A transponder carrier according to claim 1, wherein the bonding layer is composed of a non-productive rubber utilizing curatives from either an adhesive or an uncured compound of the rubber article into which the transponder carrier is embedded.

12. A transponder carrier for embedded incorporation into a rubber article, the carrier comprising:

a. a bonding layer;

b. a base layer affixed to the bonding layer, the base layer having a support surface for supporting a transponder device;

c. a reinforcement cap composed at least partially of textile cord reinforced rubber affixed to the base layer supporting surface over the transponder device, the cap textile cords being in a substantially quadrilateral woven configuration.

13. A transponder carrier according to claim 12, wherein the transponder device is at least partially coated with an adhesive bonding the transponder device to the cap and to the base layer.

14. A transponder carrier according to claim 13, wherein a ratio of the cap to transponder device areas is within a range of 2:

1 to 8;

1.

15. A transponder carrier according to claim 13, wherein the base layer is composed of a productive non-reinforced rubber.

16. A transponder carrier according to claim 13, wherein the bonding layer is composed of a non-productive rubber utilizing curatives from either an adhesive or an uncured compound of the rubber article into which the transponder carrier is embedded.
