Beam power with receiver impingement detection
First Claim
Patent Images
1. A system for supplying beamed power, comprising:
- a power beaming unit configured to supply power to a receiving unit in the form of a power beam;
a guard beaming unit configured to produce a guard beam configured to substantially surround the power beam and differing in modulation, polarization, or character from the power beam; and
a beam interruption unit configured to respond to a direction from the receiving unit to prevent a detected imminent impingement on the power beam.

27. A system for receiving beamed power from a power source, the beamed power including a guard beam substantially surrounding a power beam and differing in modulation, polarization, or character from the power beam, comprising:
-
a power receiving unit configured to accept the power beam; a detection unit configured to recognize an imminent impingement on the power beam by detecting an impingement on the guard beam; and a beam interruption signaling unit configured to transmit a signal to the power source indicating interruption of the guard beam. - View Dependent Claims (28)

29. A method of supplying beamed power, comprising:
-
directing a composite power beam toward a receiving unit, the composite power beam including a main power beam and a guard beam substantially surrounding the main power beam, the guard beam differing in modulation, polarization, or character from the power beam; receiving information from the receiving unit concerning an imminent impingement on the guard beam; and responding to prevent the imminent impingement on the power beam. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)
