Abstract

A golf club including a swing analyzer includes an accelerometer that measures acceleration in three directions, a magnetometer/gyroscope unit, a processor unit that converts the measured acceleration and golf club movement during a non-ball-striking or ball-striking swing into an estimated carrying distance of a golf ball when struck by the golf club based on swing position and a type of the golf club, and a display that displays the estimated carrying distance as a function of swing position to the golfer. The accelerometer, magnetometer/gyroscope unit, and processor unit may be mounted in a handle at a grip end of the golf club. The estimated carrying distance calculation may be performed at a unit separate from the golf club and capable of performing this calculation for several golf clubs with which it communicates via cooperating communications unit.

Claims

1. A golf club, comprising:

an accelerometer that measures acceleration in three directions;

a processor unit coupled to said accelerometer and that converts acceleration measured by said accelerometer during a non-ball-striking swing into an estimated carrying distance of a golf ball when struck by the golf club based on swing position and a type of the golf club; and

a display coupled to said processor unit and that is controlled by said processor unit to display the estimated carrying distance as a function of swing position, said display having an exposed display surface visible from an exterior of the golf club.

2. The golf club of claim 1, further comprising a handle having a grip end, said accelerometer and said processor unit being part of a swing analyzer tool mounted in said handle at said grip end.

3. The golf club of claim 2, wherein said swing analyzer tool further comprises a power source that provides power to said accelerometer and said processor unit when necessary.

4. The golf club of claim 2, wherein said swing analyzer tool further comprises a magnetometer unit coupled to said processor unit for determining at least a club face position at impact with a golf ball and a club position before impact and subsequent to impact.

5. The golf club of claim 1, wherein said processor unit is input with the type and characteristics of a golf club.

6. A method for displaying estimated carrying distance of a golf ball as a function of swing position for a golf club, comprising:

in a training stage, for each of at least one swing position,

measuring, using an accelerometer on the golf club, acceleration of the golf club during a non-ball-striking swing in three directions; and

converting, using a processor unit on the golf club, the measured acceleration into an estimated carrying distance of a golf ball when struck by the golf club based on the swing position and a type of the golf club;

storing the estimated carrying distance for each swing position in a data storage unit on the golf club; and

displaying on a display the estimated carrying distance as a function of swing position.

7. The method of claim 6, wherein the training stage involves a plurality of different swing positions.

8. The method of claim 6, further comprising inputting the type and characteristics of a golf club to the processor unit.

9. The method of claim 6, further comprising:

repeating the acceleration measuring and converting steps for each swing position to obtain a plurality of estimated carrying distances for the same swing position; and

averaging the plurality of estimated carrying distances for each swing position;

storing the average estimated carrying distance for each swing position in the data storage unit; and

displaying on the display, the average estimated carrying distance as a function of swing position.

10. A golf swing analysis arrangement, comprising:

at least one golf club, each of said at least one golf club comprising;

an accelerometer that measures acceleration in three directions; and

a first communications unit that transmits the measured acceleration; and

a unit separate and apart from the at least one golf club and that comprises;

a second communications unit arranged to communicate with the first communications unit of each golf club and receive the measured acceleration;

a processor unit that converts the received measured acceleration into an estimated carrying distance of a golf ball when struck by the golf club based on swing position and a type of the golf club; and

a display coupled to said processor unit and that is controlled by said processor unit to enable display of the estimated carrying distance as a function of swing position.

11. The arrangement of claim 10, wherein said at least one golf club comprises a plurality of golf clubs.

12. The arrangement of claim 10, wherein said separate unit further comprises a storage unit that stores information about the carrying distance of each club as a function of swing position

13. The arrangement of claim 10, wherein said accelerometer and said first communications unit are part of a swing analyzer measurement portion arranged in a grip end of a handle of each golf club.

14. The arrangement of claim 10, further comprising a magnetometer unit coupled to said processor unit for determining at least a club face position at impact with a golf ball and a club position before impact and subsequent to impact.

15. The arrangement of claim 13, wherein said swing analyzer measurement portion further comprises an additional processor unit arranged to control transmission of measured acceleration from said golf club.

16. The arrangement of claim 13, wherein said swing analyzer measurement portion further comprises a power source that provides power to said accelerometer and said first communications unit, when necessary.

17. A method for enabling a golfer to obtain estimated carrying distance of a golf ball as a function of swing position for at least one golf club, comprising:

in a training stage, for each of at least one swing position,

measuring, using an accelerometer/magnetometer/gyroscope unit on the golf club, acceleration, club face data and swing data of the golf club during a non-ball-striking swing in three directions; and

transmitting, using a first communications unit on the golf club, the measured acceleration, club face data and swing data to a second communications unit on a separate unit; and

converting, using a processor unit at the separate unit, the measured acceleration, club face data and swing data provided by the first communications unit of each golf club into an estimated carrying distance of a golf ball when struck by that golf club based on the swing position and a type and characteristics of that golf club;

whereby the estimated carrying distance of a golf ball when struck by each golf club is available as a function of swing position.

18. The method of claim 17, further comprising inputting the type of each golf club to the processor unit.

19. The method of claim 17, further comprising displaying the estimated carrying distance for each golf club as a function of swing position.

20. The method of claim 17, further comprising storing the estimated carrying distance for each swing position for each golf club in a data storage unit on the separate unit.

21. The method of claim 17, further comprising:

repeating the acceleration measuring and transmitting steps for each swing position to obtain a plurality of estimated carrying distances for the same swing position; and

averaging, at the processor unit of the handheld unit, the plurality of estimated carrying distances for each swing position for each golf club; and

displaying the average estimated carrying distance for each golf club as a function of swing position.
