Abstract
A beam power source transmits a signal indicating power availability, receives a request for power in response, and beams power in response to the request.
Claims53
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.
1 more element
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.
