Abstract

An electronically identifiable golf ball having a passive transponder implanted therein. The transponder is surrounded by a layer of elastic material which is then surrounded by a rigid housing to protect the passive transponder from the external forces applied to the golf ball.

Claims

1. A system comprising:

a golf ball;

a glass encapsulated passive transponder implanted within the golf ball for receiving energy from an external source and using said energy to transmit a distinct code signal;

an energy source for transmitting energy to the passive transponder;

a reader for receiving the distinct code signal transmitted by the passive transponder; and

wherein the glass encapsulated passive transponder is surrounded by an elastic material and both the elastic material and the glass encapsulated passive transponder are inside a rigid housing.

2. The system of claim 1 wherein the rigid housing is a metallic tube.

3. The system of claim 2 wherein the metallic tube is made from aluminum, and the tube has a slit therein to allow transmissions from the transponder to effectively escape the tube.

4. The system of claim 3 further comprising a spacer of elastic material in the slit in the metallic tube to keep the slit in the metallic tube from closing when the golf ball is hit.

5. The system of claim 4 wherein the spacer is nylon.

6. The system of claim 2 wherein elastic material between the glass encapsulated transponder and metallic tube is silicone tubing.

7. An electronically identifiable golf ball comprising:

a golf ball;

a transponder implanted within the golf ball;

a rigid housing surrounding said transponder;

an elastic material between the transponder and the rigid housing to further absorb shock when the golf ball is hit.

8. An electronically identifiable golf ball of claim 7 wherein the rigid housing is made from a metallic material.

9. An electronically identifiable golf ball of claim 8 wherein the rigid housing is a metallic tube with two ends and a length.

10. An electronically identifiable golf ball of claim 9 wherein the metallic tube has apertures at each end of said tube.

11. An electronically identifiable golf ball of claim 10 wherein the metallic tube has a slit running the length of said tube.

12. An electronically identifiable golf ball of claim 11 further comprising a spacer of elastic material in the slit in the metallic tube to keep the slit in the metallic tube from closing when the golf ball is hit.

13. An electronically identifiable golf ball of claim 12 wherein the spacer is nylon.
