GOLF CLUB APPARATUSES AND METHODS

WIPO Patent Application WO/2013/081890

A3

Methods, apparatuses, machine readable non-transitory storage media, and systems which process measured light values in order to determine the status of a golf club relative to a golf club bag are described. In one embodiment, a system uses a floating threshold, which is between a running bright average and a running dark average, to determine whether to add a current light meter value to one or the other of these running averages. In another embodiment, a system resets or re-seeds the running averages so that re-seeded averages are used after exiting from a sleep state such as a dark sleep state. In another embodiment, a system uses light sensor information or other sensor information to determine when a club is in use. In another embodiment, an active golf ball tag includes a sensor (e.g. one or more impact sensors) to detect when a golf ball is hit and to cause an RF transmitter to transmit an RF signal to an RFID reader.
