Abstract: A wireless electronic tracking system is disclosed in which a host apparatus contains an integral monitoring device capable of using power and/or timer, and/or user interface functions of the host apparatus. The monitoring device is further adapted for wirelessly tracking one or more tags deployed with a certain proximity. The monitoring device uses a wireless transceiver programmed for periodically instigating a tag to send a signal, monitoring received tag signals, and indicating to a user the identity of unresponsive tags.

Abstract: A hand held electronic game having sensors requiring the user to perform functions similar to those required during the activity simulated by the game. In a hand held electronic bowling game, both finger-movement sensors and game-moving sensors require the user to grip and swing the game housing much like swinging a bowling ball while finger-receiving sensors measure movement in the fingers and game housing-movement sensors measure the forcefulness and speed of the user's swing with the ball. The sensors include printed circuit boards and the game-moving sensor can utilize a LED and a photodiode along with a periodically transparent extension, which moves between the LED and the photodiode to determine the force of the swing by centrifugal force.
