Specification

I/WE CLAIM:
1. A wireless charging device, comprising:
a concave-shaped charging platform defining a charging area;
at least one transmitter coil arranged about the charging platform; and logic to:
initiate a power charging sequence at the charging area via transmission of a pulsed
signal to the at least one transmitter coil to induce an electromagnetic field from the at least
one transmitter coil into the charging area.
2. The wireless charging device of claim 1, wherein the at least one transmitter coil extends in a spiral about the charging platform.
3. The wireless charging device of claim 1, wherein the at least one transmitter comprises an array of transmitter coils arranged around the charging platform.
4. The wireless charging device of claim 3, wherein the array of transmitter coils comprises:
a first transmitter coil provided at a first region of the charging platform;
a second transmitter coil provided at a second region of the charging platform; and
a third transmitter coil provided at a third region of the charging platform.
5. The wireless charging device of claim 4, wherein the logic is to selectively transmit a pulsed signal to at least one of the first transmitter coil, the second transmitter coil and the third transmitter coil to initiate the power charging sequence.
6. The wireless charging device of claim 1, wherein the electromagnetic field is to have a predetermined angle of incidence relative to a plane of the at least one receiver coil.
7. The wireless charging device of claim 6, wherein the predetermined angle of incidence is substantially ninety-degrees.

8. The wireless charging device of any one of claims 1 to 7, further comprising at least one sensor configured to detect a presence of at least one electronic device, wherein the logic is to initiate the power charging sequence at the charging area based upon the detection.
9. A method of wirelessly charging an electronic device, comprising:
initiating a power charging sequence at a concave-shaped charging surface defining a charging area inducement of at least one electromagnetic field into the charging area.
10. The method of claim 9, wherein initiating the power charging sequence comprises selectively transmitting a charge signal to at least one region of the charging surface.
11. The method of claim 9 wherein initiating the power charging sequence comprises selectively transmitting a pulse signal to at least one transmitter coil.
12. The method of claim 11, wherein the at least one electromagnetic field is induced in an array of transmitter coils arranged around the charging platform.
13. The method of claim 9, wherein the at least one electromagnetic field is induced in one or more of a first transmitter coil provided at a first region of the charging platform, a second transmitter coil provided at a second region of the charging platform and a third transmitter coil provided at a third region of the charging platform.
14. The method of claim 9, wherein initiating the power charging sequence comprises inducing at least one electromagnetic field having a predetermined angle of incidence relative to a plane of at least one receiver coil.
15. The method of claim 14, wherein the predetermined angle of incidence is
substantially ninety degrees.
16. The method of any one of claims 9 to 15, further comprising detecting a removal
of the electronic device from the charging area.

17. The method of claim 16, further comprising automatically ending the power charging sequence when removal of the electronic device from the charging area has been detected.
18. A wireless charging device, comprising:
means for charging at least one electronic device, said means having a concave shaped charging station defining a charging area and at least one transmitter coil arranged about the charging platform;
means for initiating a power charging sequence at the charging area via transmission of a pulsed signal to the at least one transmitter coil to induce an electromagnetic field from the at least one transmitter coil into the charging area.
19. The wireless charging device of claim 18, wherein the at least one transmitter coil extends in a spiral about the charging platform.
20. The wireless charging device of claim 18, wherein the at least one transmitter comprises an array of transmitter coils arranged around the charging platform.
21. The wireless charging device of claim 20, wherein the array of transmitter coils comprises:
a first transmitter coil provided at a first region of the charging platform;
a second transmitter coil provided at a second region of the charging platform; and
a third transmitter coil provided at a third region of the charging platform.
22. The wireless charging device of claim 21, wherein the means for initiating a power charging sequence at the charging area is configured to selectively transmit a pulsed signal to at least one of the first transmitter coil, the second transmitter coil and the third transmitter coil.
23. The wireless charging device of claim 18, wherein the electromagnetic field is to have a predetermined angle of incidence relative to a plane of the at least one receiver coil.

24. The wireless charging device of claim 23, wherein the predetermined angle of
incidence is substantially ninety-degrees. I
