Wireless Power Transmission System
First Claim
1. A wireless power transmission system comprising:
- a transmitter comprising a control system that controls a beam source that generates a beam, and controls a beam scanner that directs the position of the beam;
a receiver comprising a beam partitioner optically connected to a reflector and an energy collector, where the beam partitioner receives the beam and partitions the beam so that a first part of the beam hits the reflector and becomes a reflected beam, and a second part of the beam hits the energy collector;
a position sensor that receives the reflected beam and sends to the control system a position sensor signal that contains characteristics of the reflected beam; and
the control system further performs the steps of;
receiving the position sensor signal;
based on position sensor signal, sending a beam modification signal to the beam source commanding the beam source to modify the beam; and
based on position sensor signal, sending a beam adjustment signal to the beam scanner to adjust the position of the beam.

Abstract
A novel method for wireless power transmission that comprises a transmitter and a receiver is disclosed. The receiver does not require an independent power source and is comprised of an optical feedback to the transmitter, and therefore does not require a separate communication channel to the transmitter. The transmitter uses the optical feedback to locate and track the receiver. The transmitter can optionally employ a macro adjusters and micro adjusters that direct the beam onto the receiver for optimal power transmission. The system also optionally has a tight loop beam detector to enhance safety of the system. Either the receiver and/or the transmitter may also encode data on the energy transmission, resulting in one-way or two-way data transmission.

36. A method for wireless power transmission in a system comprising a transmitter and a receiver, comprising the steps of:
-
a. transmitting a low-powered and defocused beam from the transmitter;
b. reflecting at least a portion of the beam from the receiver back to the transmitter;
c. monitoring for the detection of a reflected beam at the transmitter;
d. once the presence of a reflected beam is detected, focusing the beam and directing the beam to the area where the reflected beam was detected;
e. adjusting the beam with macro and micro adjusters until a reflected beam with desired characteristics is detected at the transmitter;
f. once the reflected beam with desired characteristics is detected at the transmitter, increasing the power of the beam;
g. adjusting the beam with macro and micro adjusters to maintain the desired characteristics of the reflected beam, as detected at the transmitter; and
h. powering down the beam when the characteristics of the reflected beam, as detected at the transmitter, become undesirable. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)
