Wireless power beaming to common electronic devices
First Claim
1. An apparatus to provide electricity to devices, the improvement wherein no wires are required to carry the electricity comprising:
- a. an eye-safe light source that converts electricity to optical power beam, b. optics and mechanics to shape and point the optical power beam beam at an optical-to-electric power converter, c. free space d. an optical-to-electric power converter e. a safety subsystem that accounts for the optical power to within regulatory limits and controls when to beam is on or off to assure humans near to the light, as within a room, are exposed within regulatory limits.

Abstract
A method and apparatus for wireless power beaming consisting of a transmitter assembly (20), free space (40), and an optical-to-electric assembly (50). The transmitter assembly (20) has eye-safe lasers (26) that create a beam of light (90). The beam of light goes through free space (40) and impinges upon the surface of optical-to-electric assembly (50). Optical-to-electric assembly (50) has power conversion photodiode(s) (54) to convert the energy in the light (90) into electricity. Power Accounting (14) accounts for the power in the beam and controls the lasers to turn them off whenever radiation is not accounted for in the system.
