Beam power with beam redirection
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.
1. A system for supplying beamed power, comprising:
a location unit configured to locate a receiving unit in need of power by
broadcasting a beam indicative of its ability to supply power; and
receiving a request for power from the receiving unit in response to the broadcast beam;
a first beam-directing mechanism configured to change direction of a power beam; and
a power beaming unit remote from the beam-directing mechanism, configured to beam power to the receiving unit by sending a power beam in a path selected to reach the receiving unit via the beam-directing mechanism.
2. The system of claim 1 , wherein the power beaming unit is further configured to locate the beam-directing mechanism.
3. The system of claim 1 , wherein the location unit is further configured to locate the beam-directing mechanism and to communicate the location of the beam-directing mechanism to the power beaming unit.
4. The system of claim 1 , further comprising a second beam-directing mechanism.
5. The system of claim 4 , further comprising beam-directing mechanism selection circuitry configured to direct the power beaming unit to direct the beam toward either the first or the second beam-directing mechanism.
6. The system of claim 1 , wherein the first beam-directing mechanism is configured to dynamically adjust the direction of the power beam to follow a moving power receiver.
7. The system of claim 1 , wherein the location unit is colocated with the power beaming unit.
8. The system of claim 1 , wherein the location unit is colocated with the first beam-directing mechanism.
9. The system of claim 1 , wherein the power beaming unit is configured to beam power within an enclosed space.
10. The system of claim 1 , wherein the power beaming unit is configured to gradually increase an amount of power beamed from the power beaming unit.
11. The system of claim 1 , wherein the power beaming unit is configured to beam electromagnetic power.
12. The system of claim 11 , wherein the electromagnetic power has an optical frequency.
13. The system of claim 11 , wherein the electromagnetic power has an RF frequency.
14. The system of claim 1 , wherein the power beaming unit includes a laser that generates a power beam.
15. The system of claim 1 , wherein the power beaming unit is configured to beam pulsed power.
16. The system of claim 1 , wherein the power beaming unit is configured to beam power continuously.
17. A system for supplying beamed power, comprising:
a location unit configured to locate a receiving unit in need of power by receiving a request for power from the receiving unit;
a first beam-directing mechanism configured to change direction of a power beam; and
a power beaming unit remote from the beam-directing mechanism, configured to beam power to the receiving unit by sending a power beam in a path selected to reach the receiving unit via the beam-directing mechanism.
18. The system of claim 17 , wherein the power beaming unit is further configured to locate the beam-directing mechanism.
19. The system of claim 17 , wherein the location unit is further configured to locate the beam-directing mechanism and to communicate the location of the beam-directing mechanism to the power beaming unit.
20. The system of claim 17 , further comprising a second beam-directing mechanism.
21. The system of claim 20 , further comprising beam-directing mechanism selection circuitry configured to direct the power beaming unit to direct the beam toward either the first or the second beam-directing mechanism.
22. The system of claim 17 , wherein the first beam-directing mechanism is configured to dynamically adjust the direction of the power beam to follow a moving power receiver.
23. The system of claim 17 , wherein the location unit is colocated with the power beaming unit.
24. The system of claim 17 , wherein the location unit is colocated with the first beam-directing mechanism.
25. The system of claim 17 , wherein the power beaming unit is configured to beam power within an enclosed space.
26. The system of claim 17 , wherein the power beaming unit is configured to gradually increase an amount of power beamed from the power beaming unit.
27. The system of claim 17 , wherein the power beaming unit is configured to beam electromagnetic power.
28. The system of claim 27 , wherein the electromagnetic power has an optical frequency.
29. The system of claim 27 , wherein the electromagnetic power has an RF frequency.
30. The system of claim 17 , wherein the power beaming unit includes a laser that generates a power beam.
31. The system of claim 17 , wherein the power beaming unit is configured to beam pulsed power.
32. The system of claim 17 , wherein the power beaming unit is configured to beam power continuously.
