Abstract

An instrumented golf club system having an instrumented golf club, an interface means and a computing means is disclosed herein. The instrumented golf club includes a plurality of sensors, an internal power supply, an angular rate sensor and an internal ring buffer memory for capturing data relating to a golf swing. The interface means is capable of transferring data from the instrumented golf club to the computing means for processing the data and presenting the data in a useful and informative format. The data may be used to assist a golfer'"'"'s swing, or to design an appropriate golf club for a specific type of golfer.

Claims

1. An instrumented golf club system comprising:

an instrumented golf club, the instrumented golf club comprising

a club head and a shaft attached to the club head,

at least one sensor disposed on or within the golf club, the at least one sensor capable of measuring data related to the club head or the shaft during a golf swing, and

an internal memory device capable of receiving and storing data from the at least one sensor, the internal memory device disposed on or within the golf club;

a computer for processing the data from the internal memory device; and

an interface mechanism capable of providing communication between the instrumented golf club and the computer;

wherein the club head further comprises a first contact point and the interface mechanism further comprises a first pin, the first contact point and the first pin being mateably adapted for electronically communicating data from the instrumented golf club to the computer.

2. The instrumented golf club system according to claim 1 wherein the club head comprises a second contact point and the interface mechanism comprises a second pin, the second contact point and the second pin being mateably adapted for electronically communicating data from the computer to the instrumented golf club.

3. An instrumented golf club system comprising:

an instrumented golf club, the instrumented golf club comprising

a club head and a shaft attached to the club head,

at least one sensor disposed on or within the golf club, the at least one sensor capable of measuring data related to the club head or the shaft during a golf swing, and

an internal memory device capable of receiving and storing data from the at least one sensor, the internal memory device disposed on or within the golf club;

a computer for processing the data from the internal memory device; and

an interface mechanism capable of providing communication between the instrumented golf club and the computer;

wherein the club head further comprises a first contact point and the interface mechanism further comprises a first pin, the first pin capable of providing external power to the instrumented golf club via the first contact point.

4. A method for measuring and storing golf swing data, the method comprising:

placing an instrumented golf club into a ready state;

recording data from at least one sensor disposed within or on the instrumented golf club, the data recorded to an internal memory device disposed on or within the instrumented golf club;

sensing a first impact threshold triggering event by the instrumented golf club;

saving data to the internal memory device for a first predetermined period of time prior to the first impact threshold triggering event and a second predetermined period of time following the first impact threshold triggering event;

placing the instrumented golf club into an interface mechanism wherein the instrumented golf club comprises a first contact point and the interface mechanism comprises a first pin, the first contact point and the first pin being mateably adapted for communication between the instrumented golf club and the computer; and

communicating the data from the internal memory device of the instrumented golf club to a computer via the interface mechanism.

5. The method according to claim 4 wherein the first predetermined period of time is greater than the second predetermined period of time.

6. The method according to claim 4 wherein the internal memory device continually records data in increments of 2 milliseconds or less.

7. The method according to claim 4 wherein the at least one sensor is a first angular rate sensor, the first angular rate sensor capable of directly measuring an angular rotation rate at a predetermined location on or within the instrumented golf club.

8. The method according to claim 4 further comprising:

storing the data into a data block on the internal memory device;

sensing a plurality of impact threshold triggering events by the instrumented golf club, each of the plurality of impact threshold events resulting in data being saved to a corresponding data block on the internal memory device, data from each of the plurality of impact threshold events comprising data for a predetermined period of time prior to each of the plurality of impact threshold triggering events and a second predetermined period of time following each of the plurality of impact threshold triggering events.

9. The method according to claim 4 further comprising recording data from a plurality of sensors to the internal memory device.

10. A method for measuring, storing, transferring and presenting golf swing data, the method comprising:

placing an instrumented golf club into a ready state;

recording data from at least one sensor disposed within or on the instrumented golf club, the data recorded to an internal memory device disposed on or within the instrumented golf club;

sensing a first impact threshold triggering event by the instrumented golf club;

saving data to the internal memory device for a first predetermined period of time prior to the first impact threshold triggering event and a second predetermined period of time following the first impact threshold triggering event;

placing the instrumented golf club in communication with an interface mechanism capable of transferring data from the instrumented golf club to a computer wherein the instrumented golf club comprises a first contact point and the interface mechanism comprises a first pin, the first contact point and the first pin being mateably adapted for communication between the instrumented golf club and the computer;

processing the data in the computer; and

presenting the data in a visual format.

11. The method according to claim 10 further comprising manipulating the data to transform the data into a pictorial representation of a predetermined portion of a golfer'"'"'s actual recorded golf swing.

12. The method according to claim 10 further comprising manipulating the data to transform the data into a pictorial representation of a golf club head travelling through a golf ball impact region.

13. The method according to claim 10 wherein the at least one sensor is a first angular rate sensor, the first angular rate sensor capable of directly measuring an angular rotation rate at a predetermined location on or within the instrumented golf club.

14. The method according to claim 10 further comprising recording data from a plurality of sensors to the internal memory device.

15. The method according to claim 14 wherein the plurality of sensors comprises at least one strain sensor and at least one acceleration sensor.

16. The method according to claim 10 wherein the internal memory device is a ring buffer memory, the ring buffer memory capable of continually recording data when the instrumented golf club is in a ready state, and capable of capturing data both prior to and following an impact threshold triggering event.
