Patent ID: 8330284

Claim:
A method for wirelessly charging a motion-sensitive input device comprising a housing sized and adapted to be held in the air and manipulated by a user to control or activate one or more desired play effects within a game at least in part by moving, shaking, twisting, waving or pointing said input device, the housing having an internal cavity formed therein sized and adapted to receive and contain one or more batteries for powering said input device, said method comprising: inserting into said internal cavity a magnetic inductance energy generator comprising i) an inductance coil or wire sized and arranged such that when it is exposed to a fluctuating magnetic field electrical pulses are generated, ii) a rectifier configured to convert said electrical pulses into storable electrical energy, and iii) a capacitor or rechargeable battery for storing said storable electrical energy for powering said input device; and exposing said inductance coil or wire to a fluctuating magnetic field to thereby generate said electrical pulses and wirelessly charge said input device with said stored electrical energy, whereby said input device can be wirelessly charged and operated by a user to control or activate said one or more desired play effects without wires or electrical connectors between said input device and an external energy source.
