Abstract

The present invention provides wireless power supply systems that wirelessly supply power to a remote device for rapidly charging a charge storage capacitor, which charges a battery with the power stored in the charge storage capacitor. This allows the remote device to be positioned near the inductive power supply for rapid charging of the charge storage capacitor and allows battery charging to continue even after the remote device is removed from the inductive power supply.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A wireless charging system comprising:
an inductive power supply for supplying wireless power from a primary; and
a remote device separable from said inductive power supply, wherein said remote device includes a secondary power circuit, a charge storage capacitor, a charging subcircuit, and a battery;
said secondary power circuit is electrically connected to said…
