Abstract: A golf swing monitoring system in the form of a one piece, wrist mounted unit which includes multi-function instrumentation with extremely high degrees of precision that monitors a plurality of critical components of a golf swing. In particular, motion sensors that discriminate finite changes in the timing and speed of the swing are disposed in a housing mounted on a wrist bank analogous to a common wrist watch or timepiece. A third component, user grip pressure, is simultaneously monitored and is similarly housed in the watch housing or casement. The detected parameters are displayed on a LCD which is part of the instrumentation. Finally the calculated values of the swing components can be saved in the memory of the invention. Subsequent swings are compared with those saved and the degrees to which later swings conform or deviate from the values for the saved swing are displayed. The subject invention has a skill level setting, 1 to 5 where 1 is the highest skill level, 5 the least.

Abstract: The power source for the Shotwatch™, a wrist worn, microprocessor based swing monitor, is a three volt, coin sized battery such as the Duracell DL 2032. Given the voltage requirements of the swing monitor, as well as the size and space constraints imposed by the wrist watch embodiment, a newly designed battery assembly was required. The assembly was patterned after a common Compact Disc/DVD carriage which would allow easy replacement by the user. Additionally, the carriage needed to be designed with fail-safes such as making it difficult or impossible to insert the battery or the carriage itself incorrectly, resulting in serious damage or destruction of the Shotwatch™. Contact points, springs and release mechanisms were deployed in an optimal manner to accomplish the dual objectives of a reliable power source and an assembly that would prove viable in possible hostile environments.
