Optical battery recharger
First Claim
1. A device for recharging one or more batteries of an electrical or electronic appliance, comprising:
- a. an internal unit built integrally within said appliance and having at least one photovoltaic receptor connected to a battery charging circuit for converting optical power to electrical power to recharge said one or more batteries of said appliance;
b. an external unit positioned adjacent to said internal unit and having a solid-state light source connected to and powered by an electrical power source for emitting a light beam to said at least one photovoltaic receptor;
c. said internal unit having means for allowing said at least one photovoltaic receptor to receive said light beam emitted from said light source;
d. said external unit having means for focusing said light beam emitted from said light source and to be received by said at least one photovoltaic receptor; and
e. said external unit having a receptacle for housing said light source and having means for aligning said at least one photovoltaic receptor to said light source when said device is used to recharge said one or more batteries;
f. whereby said device can be positioned adjacent to said internal unit with said at least one photovoltaic receptor of said external unit aligned to said light source of said internal unit for recharging said one or more batteries of said appliance.

Abstract
An optical battery recharger for recharging batteries of an electrical or electronic appliance. The recharger includes an internal unit built integrally within the appliance. The internal unit has one or more photovoltaic receptors connected to a battery charging circuit for converting optical power to electrical power to recharge the batteries. The recharger also has an external unit which has a solid-state light source connected to and powered by an electrical power source, a lens for focusing the light emitted from the light source, possibly through an aperture, onto the photovoltaic receptors, and a receptacle for aligning the photovoltaic receptor to the light source of said external unit when the recharger is used to recharge the batteries.
