Systems and methods for archery equipment

1. A method of evaluating a performance of at least one of archery equipment and an archer, the archery equipment including an arrow and a bow having a bow string, the method comprising acts of:

generating flight-data for at least one point in a flight of the arrow shot from the bow the at least one point located between a launch point that occurs when the arrow disconnects from the bow string and an impact point that occurs when the arrow strikes a target, the flight-data generated with a sensor included in the arrow; and

evaluating the performance of the at least one of the archery equipment and the archer using the flight-data.

2. The method of claim 1 , further comprising an act of including the sensor in at least one of a nock and an arrow tip configured for removable attachment to the arrow.

3. The method of claim 1 , further comprising acts of communicating the flight-data to a device external to the arrow; and processing the flight-data to provide quantitative information concerning at least one flight characteristic of the arrow.

4. The method of claim 3 , wherein the at least one flight characteristic includes a velocity of the arrow in flight.

5. The method of claim 4 , further comprising an act of providing the velocity of the arrow for a plurality of points along a flight path of the arrow.

6. The method of claim 5 , wherein the velocity includes an instantaneous velocity.

7. The method of claim 4 , further comprising an act of providing the velocity of the arrow at each of the launch point and the impact point.

8. The method of claim 3 , further comprising an act of generating a graphical display concerning the at least one flight characteristic.

9. The method of claim 8 , further comprising an act of displaying a plot of instantaneous values of the at least one flight characteristic.

10. The method of claim 9 , further comprising an act of displaying the plot as a continuous function.

11. The method of claim 8 , wherein the at least one flight characteristic includes any of a pitch of the arrow, a roll of the arrow and a yaw of the arrow.

12. The method of claim 1 , further comprising an act of displaying a flight path of the arrow from the launch point to the impact point.

13. The method of claim 12 , wherein the act of displaying the flight path includes an act of displaying any of the pitch of the arrow, an angular rotation of the arrow about a longitudinal axis of the arrow and the yaw of the arrow at one or more locations along the flight path.

14. The method of claim 1 , further comprising an act of communicating the flight-data to a device external to the arrow using at least one of a wired communication and a wireless communication.

15. The method of claim 14 , wherein the act of communicating includes an act of wirelessly communicating the flight-data via an optical signal.

16. The method of claim 1 , further comprising an act of employing the flight-data to determine a kinetic energy of the arrow for at least one location along a flight path of the arrow.

17. A computer readable medium encoded with a program for execution on a processor, the program when executed on the processor performing evaluating a performance of at least one of archery equipment and an archer, the archery equipment including an arrow and a bow having a bow string, the method comprising acts of:

receiving flight-data generated, with a sensor included in the arrow for at least one point in a flight of the arrow, the at least one point located between a launch point that occurs when the arrow disconnects from the bow string and an impact point that occurs when the arrow strikes a target; and

generating, based on the flight-data, at least one recommended adjustment to improve a subsequent flight of the arrow.

18. A method of tuning archery equipment including a bow and arrow, the method comprising:

employing an arrow-mounted sensor to measure data for a shot taken with the archery equipment; and

evaluating the measured data to determine at least one adjustment to the archery equipment to improve a performance of the archery equipment.

19. The method of claim 18 , wherein the shot is a first shot, wherein the method further comprises acts of:

adjusting the archery equipment;

employing the arrow-mounted sensor to measure data for a subsequent shot taken with the archery equipment; and

comparing the measured data for the subsequent shot with the measured data for the first shot.

20. The method of claim 18 , further comprising displaying the measured data in a user interface.
