Method for monitoring performance characteristics associated with user activities involving swinging instruments

1. A method of device assembly for attachment to a swinging instrument, comprising:

assembling positive and negative electrical contacts with a chassis,

positioning a printed circuit board on the chassis to form a chassis assembly, the chassis supporting the printed circuit board thereon,

assembling the chassis assembly with a cap to form a cap assembly, and

mating the cap assembly with a base, the base including a fastening portion and a support portion,

wherein the support position includes a first side opening and a second side opening,

wherein the support portion supports the chassis, the printed circuit board, the positive and negative electrical contacts, and the cap, and

wherein in the mated configuration, the cap assembly and the base form a battery opening configured and dimensioned to receive therethrough a battery, and remaining exposed to provide access to the battery, via the first and second side openings.

2. The method according to claim 1 , comprising detachably interlocking a cover relative to the base to cover the cap assembly.

3. The method according to claim 2 , comprising positioning a retaining ring within a circumferential groove in an inner surface of the cover to detachably interlock the cover relative to the base.

4. The method according to claim 1 , comprising attaching the fastening portion of the base to a swinging instrument.

5. The method according to claim 1 , wherein the device attaches to the end portion of a swinging instrument.

6. The method according to claim 1 , wherein the cover comprises a depressible button on a top surface for actuating an actuator on the printed circuit board.

7. The method according to claim 1 , comprising a water-resistant cap assembly that encapsulates the internal components.

8. The method according to claim 1 , wherein the support portion of the base comprises a first side opening and a second side opening, at least a portion of the first side opening forming the battery opening.

9. The method according to claim 1 , wherein in the mated configuration, the cap and the base form an opening configured and dimensioned to receive an instrument therethrough to eject the battery.

10. A method of detecting an impact between a swinging instrument and an object, the method comprising:

providing an sensor assembly having a resilient cover configured to encapsulate an upper portion of the sensor assembly and selectively engage a base of the sensor assembly;

removing the resilient cover to expose integrally formed structure including cap assembly a portion of the base, the integrally formed structure having a first side opening configured to receive a battery and a second side opening configured to receive an instrument to eject the battery through the first side opening, the first and second side openings being opposingly spaced from each other, the first side opening being larger than the second side opening;

determining whether an impact occurred between the object and the swinging instrument,

thereon transmitting swing information from a sensor module to a remote system,

wherein the remote system can display the swing information.

11. The method according to claim 10 , comprising transmitting swing information from a sensor module to the user's electronic device.

12. The method according to claim 10 , comprising transmitting swing information to a remote system via Bluetooth.

13. The method according to claim 10 , wherein the remote system can process swing information.

14. The method according to claim 10 , comprising detecting when a user is preparing to swing the instrument.

15. The method according to claim 10 , comprising detecting when a user is swinging the instrument.

16. The method according to claim 10 , wherein the sensor module compiles the swinging information to compute performance characteristics associated with the user's use of the instrument.

17. The method according to claim 10 , comprising monitoring the user's performance to transmit and render graphical displays of the performance characteristics on a remote device.
