Title:
APPARATUS AND METHOD FOR PROVIDING ELECTRICAL ENERGY GENERATED FROM MOTION TO AN ELECTRICALLY POWERED DEVICE
Document Type and Number:
WIPO Patent Application WO2005008804
Kind Code:
A3
Abstract:
An apparatus and method for providing electrical energy to one or more functional components of electrical device and/or to recharge a rechargeable power supply of the device, by deriving the electrical energy from motion of the device, is disclosed. The inventive apparatus preferably includes one or more novel oscillating weight - based kinetic electrical power generators (KEPG) that include a novel oscillating weight having an internal cavity with a freely movable acceleration element disposed therein, resulting in improved acceleration and oscillation capabilities and lower power generation motion threshold for the KEPG. The various embodiments of the present invention disclose a variety of novel electrical devices and articles (carrying cases, clothing, etc.) incorporating, or usable in conjunction with, electrical devices, that preferably and advantageously utilize one or more novel KEPGs for generating electrical energy from motion and feeding it to the devices and/or recharging the device batteries. The inventive embodiments also include a self-recharging battery incorporating one or more KEPGs to provide a continuous recharge, a KEPG-based portable recharger capable of connection to a charging port of an electrical device, a KEPG-based motion sensor, and an electrical device with a mechanical user­ operable input that includes a dual mode electrical generator incorporating one or more KEPGs.
