First Claim
Patent Images
1. 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.
