Abstract

A wrist worn battery charging system is disclosed which may be utilized to power or charge the batteries of portable devices, such as wrist worn PDA's, wrist worn Cell-Phones, wrist worn PC's, wrist worn walkie-talkies, wrist worn MP3 players, or other electronic devices which are battery powered and worn on the body of the user. The battery charger operates by turning the motion of the user's arm into electrical energy by the action of a miniature D.C. generator. The output voltage may be used to trickle charge a battery, or supply energy necessary to sustain power for the operation of a number of portable devices. The system is sealed and encapsulated to prolong its' useful life and disguise its' appearance.

Claims5

Dependent claims

A portable battery charging system, for the charging of portable batteries as might be utilized in cellular telephones, Personal Digital Assistants (PDA's), laptop computers, portable gaming devices, and various other forms of communications equipment, where the charging system is worn on the body of the user comprising:

A permanent magnet mounted on a sled, riding back and forth on two rails, surrounded by a linear array of copper coils on both sides;
and
The above coils attached to an electronic circuitry consisting of a battery interface of diodes and capacitors for filtering of the output pulses;
and
The entire system is encapsulated in a sealed container which is filled with a lubricating liquid, such as light weight synthetic oil;
and
The system has a connecting cable that can be plugged into the charging point of the portable device whose battery is being charged.
