Abstract

Golf balls for use with a system for finding golf balls and methods for making such golf balls. In the case of one exemplary golf ball, the ball includes a shell, a core material and a tag having a diode which is coupled to an antenna which has at least a portion formed from an elastic conductive material, such as an elastic conductive ink. The core material may include a void for receiving at least part of the diode. Other golf balls are described and methods for making balls are also described.

Claims

1. A method of making a golf ball, said method comprising:

forming a first member having an outer surface, said first member forming a part of said golf ball;

depositing a liquid material which when dried forms at least one antenna which is electrically conductive;

forming a second member which surrounds said at least one antenna.

2. A method as in claim 1 further comprising:

curing said liquid material;

coupling a diode to said at least one antenna.

3. A method as in claim 1 wherein said at least one antenna is an elastic conductive material and wherein said liquid material is deposited onto said outer surface.

4. A method as in claim 3 wherein said depositing comprises at least one of (a) painting said liquid material;

(b) printing said liquid material;

(c) jetting said liquid material through a nozzle; and

(d) spraying said liquid material.

5. A method as in claim 1 wherein said first member is a core material of said golf ball, said core material having a substantially spherical shape, and said second member is a layer of material which has a circular cross-sectional shape and which encases said first member and said at least one antenna.

6. A method as in claim 5 wherein said second member is an outermost shell of said golf ball.

7. A method as in claim 5 wherein said second member is an inner shell.

8. A method as in claim 3 wherein said elastic conductive material is a conductive ink.

9. A method as in claim 1 further comprising:

forming a template on said outer surface, said template defining at least a portion of a pattern of said at least one antenna.

10. A method as in claim 1 further comprising:

forming a void in said outer surface;

depositing at least a portion of a diode in said void;

coupling said diode to said at least one antenna.

11. A method as in claim 1 wherein said at least one antenna is patterned as a radial transmission line.

12. A method as in claim 1 wherein said at least one antenna has at least one perforation which extends from a first surface of said at least one antenna to a second surface of said at least one antenna.

13. A method as in claim 1 wherein said at least one antenna comprises an inductive element.

14. A method as in claim 1 wherein said liquid material comprises a solvent, a polymer and metal particles dispersed in said polymer.

15. A method as in claim 1 wherein said at least one antenna is part of a radio frequency tag which can be used to find said golf ball and wherein said golf ball has high durability and substantially complies with golf ball specifications of the United States Golf Association.
