Abstract

The golf club reminder system for a golf bag utilizes a capacitance-based, proximity sensing system to monitor golf clubs in the golf bag. The components of the golf club reminder system are built into a golf bag, and the golf club reminder system operates in two modes. In a first normal mode the presence of a normal count of clubs in the golf bag is detected, and any absence of clubs or presence of additional clubs is silently indicated with a light. In a second security mode of operation a loud audio alert is produced at the detection of any change in club count.
