Abstract

A method and apparatus for changing the temperature pattern of the surface of a golf ball or golf club is disclosed. The apparatus includes a thermal device capable of imparting a temperature pattern onto the surface of a golf ball. The thermal device preferably imparts the temperature pattern from a distance, preferably while the golf ball is positioned on a golf tee. After a predetermined amount of time, the golf ball may be stuck by a golf club. A thermal imaging device, which may detect a cooling pattern imparted to the golf ball by prongs of a cooling device, is preferably used to acquire images of the temperature pattern. The acquired images may then be analyzed by a processor to determine the kinematic characteristics of the golf ball.

Claims

1. An apparatus for measuring the flight characteristics of golf equipment, comprising:

a golf club and a golf ball;

at least one infrared sensing device selectively positioned to acquire images of at least one of the golf club and the golf ball; and

a cooling device having at least one contact surface operable to temporarily maintain contact with at least one portion of the surface of at least one of the golf club and the golf ball to impart a temperature pattern to the at least one portion of the surface of at least one of the golf club and the golf ball;

wherein the infrared sensing device is operable to detect a temperature pattern on a portion of the surface of at least one of the golf club and the golf ball.

2. The apparatus according to claim 1, wherein the temperature pattern is imparted by cooling portions of the golf club and golf ball.

3. The apparatus according to claim 1, wherein the time period necessary to impart the temperature pattern is between about 5 seconds and about 30 seconds.

4. The apparatus according to claim 1, wherein the time period necessary to impart the temperature pattern is about 1 minute or less.

5. The apparatus according to claim 1, wherein the cooling device is operable to lower the temperature of portions of the golf club and golf ball by between about 10°

F. and about 30°

F.

6. The apparatus according to claim 1, wherein the cooling device is operable to lower the temperature of portions of the golf club and golf ball by about 20°

F.

7. The apparatus according to claim 1, wherein the cooling device comprises a plurality of protrusions that are operable to rest flush with the surface of at least one of the golf club and golf ball.

8. The apparatus according to claim 1, wherein the cooling device is operable to impart the temperature pattern to the surface of at least one of the golf club and golf ball in about 30 seconds or less.

9. The apparatus of claim 1, wherein the cooling device further comprises a coolant operable to cool at least a portion of at least two prongs.

10. The apparatus of claim 1, wherein the temperature of the cooled pattern is between about 0°

F. and about 50°

F.

11. An apparatus for determining the flight characteristics of a golf ball, comprising:

a thermal device;

a thermal imaging device operable to detect and acquire images of a temperature pattern; and

wherein the thermal device comprises a cooling device comprising two or more elements operable to impart a temperature pattern to a portion of the surface of the golf ball by contacting a portion of the surface of the golf ball for a predetermined period of time; and

wherein the images of the temperature pattern may be analyzed to determine the kinematic characteristics of the golf ball.

12. The apparatus according to claim 11, further comprising a processor operable to analyze the images of the temperature pattern.

13. The apparatus according to claim 11, wherein the difference between the temperature pattern and other portions of the golf ball is between about 10°

F. and about 30°

F.

14. The apparatus according to claim 11, wherein the difference between the temperature pattern and other portions of the golf ball is about 20°

F.

15. The apparatus according to claim 11, wherein the thermal device comprises a focused emitting device.

16. A method of determining the flight characteristics of a golf ball, comprising:

imparting a temperature pattern to localized portions of the surface of a golf ball by contacting the surface of the golf ball; and

detecting the temperature pattern based on a thermal detection device;

wherein the difference between the temperature pattern and other portions of the surface of the golf ball is between about 10°

F. and about 30°

F.; and

wherein the temperature pattern is imparted by using one or more elements to actively impart a thermal pattern by cooling the portion of the surface of the golf ball.

17. The method according to claim 16, wherein the difference between the temperature pattern and other portions of the surface of the golf ball is about 20°

F.

18. The method according to claim 16, wherein the difference between the temperature pattern and other portions of the surface of the golf ball is about 30°

F.

19. The method according to claim 16, further comprising:

acquiring images of the temperature pattern; and

processing the images to determine the kinematic characteristics of the golf ball.

20. The method according to claim 19, wherein the kinematic characteristics include at least one of side spin, back spin, trajectory, and velocity.

21. The method according to claim 16, wherein the temperature pattern is imparted in about 1 minute or less.
