Abstract

Wireless power is used to deliver power to different areas on a circuit board or on an integrated circuity. The power can be delivered by magnetic resonant power or by inductive power coupling. Optical isolation can be used between different stages.

Claims

1. An electronic system comprising:

a substrate, having a plurality of power consuming elements thereon, said power consuming elements arranged in a fixed geometry on said substrate, and at least a plurality of said power consuming elements including a wireless power receiving part, that wirelessly receives power that is sent thereto, and uses said power which is wirelessly received, to power said power consuming elements, wherein at least one of said power consuming elements receives power separately from at least another of said power consuming elements, and wherein each of said power consuming elements operates substantially simultaneously, and wherein at least one of said power consuming elements has an output connected to another of said power consuming elements.

2. An electronic system as in claim 1, wherein said substrate is printed circuit board.

3. An electronic system as in claim 1, wherein said substrate is a substrate of an integrated circuit.

4. An electronic system as in claim 1, wherein said wireless power receiving element is associated with plural different power consuming elements, forming a group, and another wireless power receiving element is associated with different power receiving elements forming a second group.

5. An electronic system as in claim 1, further comprising an optical isolator, operating between different power receiving elements to allow signals to be connected therebetween.

6. A pen electronic system as in claim 1, wherein said wireless power receiving element is an element that receives power by magnetic resonance.

7. An electronic system as in claim 1, wherein said wireless power receiving element is an element that receives power by inductive power coupling.

8. An electronic system as in claim 1, further comprising a wireless power transmitting part, associated with said electronic system.

9. An electronic system as in claim 8, wherein said wireless power transmitting part is located on said substrate.

10. An electronic system as in claim 8, wherein said wireless power transmitting part is located off of said substrate but adjacent thereto.

11. A method comprising:

delivering power wirelessly to a plurality of different power consuming elements on a substrate, including delivering first power to a first element, and delivering second power to a second element, where the first power is separately delivered from the first power.

12. A method as in claim 11, further comprising optically isolating between said first element and said second element.

13. A method as in claim 11, wherein said substrate is printed circuit board.

14. A method as in claim 11, wherein said substrate is a substrate of an integrated circuit.

15. A method as in claim 11, wherein said delivering comprises delivering power by magnetic resonance.

16. A method as in claim 11, wherein said delivering comprises delivering power by inductive power coupling.

17. A method as in claim 11, wherein said delivering comprises delivering power from a power delivery part located on said substrate.

18. A method as in claim 11, wherein said delivering comprises delivering power from a power delivery part located off said substrate.

19. An electronic system comprising:

a substrate, having a plurality of power consuming elements thereon, and at least a plurality of said power consuming elements including a wireless power receiving part, that includes an inductive coil and a capacitor, forming an RC circuit with a first resonance property and a Q of at least 1000, and uses said power which is wirelessly received to power said power consuming elements, wherein at least one of said power consuming elements receives power separately from at least another of said power consuming elements, and wherein each of said power consuming elements operates substantially simultaneously.
