Abstract

Techniques for wireless charging in a system, method, and apparatus are described herein. For example, the apparatus includes a wireless power transmitting coil configured to propagate current to generate a magnetic field. The wireless power transmitting coil is disposed in a hand-operated input device.

First claim

What is claimed is:

1 . An apparatus for wireless charging, comprising:
a wireless power transmitting coil configured to propagate current to generate a magnetic field; and wherein the wireless power transmitting coil is disposed in a hand-operated input device.

2 . The apparatus of claim 1 , wherein the wireless power transmitting coil is disposed in a platform of the hand-operated input device.

3 . The apparatus of claim 1 , wherein the wireless power transmitting coil is disposed at an angle to a planar surface upon which the hand-operated input device is configured to operate.

4 . The apparatus of claim 3 , wherein the angle is substantially perpendicular to the planar surface.

5 . The apparatus of claim 1 , wherein the wireless power transmitting coil is a component of a power propagation device disposed in the hand-operated input device.

6 . The apparatus of claim 5 , wherein the wireless power transmitting coil is a first wireless power transmitting coil, the power propagation device further comprising a wireless power receiving coil to receive a magnetic flux from a second wireless power transmitting coil disposed at a planar surface upon which the hand-operated input device is configured to operate.

7 . The apparatus of claim 6 , further comprising a phase shifting component coupling the first wireless power receiving coil to the first wireless power transmitting coil, and wherein the phase shifting component is configured to generate an impedance inversion.

8 . The apparatus of claim 1 , wherein the magnetic field comprises a flux configured to generate a charging current in a wireless power receiving coil.

9 . The apparatus of claim 8 , wherein the user operated input device is configured generate the charging current when the user operated input device is in use.

10 . The apparatus of claim 1 , wherein the hand-operated input device comprises:
a keyboard; a computer mouse; or any combination thereof.

11 . A method for forming a wireless charging apparatus, the method comprising:
providing a wireless power transmitting coil configured to propagate current to generate a magnetic field; and disposing the wireless power transmitting coil in an ergonomic component.

12 . The method of claim 11 , wherein the wireless power transmitting coil is disposed in a platform of the ergonomic component.

13 . The method of claim 11 , wherein the ergonomic component is configured to be placed on a planar surface, and wherein the wireless power transmitting coil is disposed at an angle to the planar surface.

14 . The method of claim 13 , wherein the angle is substantially perpendicular to the planar surface.

15 . The method of claim 11 , wherein the wireless power transmitting coil is a component of a power propagation device disposed in the ergonomic component.

16 . The method of claim 15 , wherein the wireless power transmitting coil is a first wireless power transmitting coil, the method further comprising providing a wireless power receiving coil of the power propagation device to receive a magnetic flux from a second wireless power transmitting coil disposed at a planar surface upon which the ergonomic component is configured to be disposed.

17 . The method of claim 16 , further comprising forming a second wireless power transmitting coil within the ergonomic component.

18 . The method of claim 11 , wherein the magnetic field comprises a flux that is configured to generate a charging current.

19 . The method of claim 18 , wherein the ergonomic component is configured to generate the charging current when the ergonomic component is in use.

20 . The method of claim 11 , wherein the ergonomic component comprises:
a support associated with a keyboard; a support associated with a computer mouse; or any combination thereof.

21 . A system for wireless charging, comprising:
a wireless power transmitting coil configured to propagate current to generate a magnetic field; and wherein the wireless power transmitting coil is disposed in a hand-operated input device; and configured to charge a chargeable device when the hand-operated input device is in use.

22 . The system of claim 21 , wherein the wireless power transmitting coil is disposed at an angle to a planar surface upon which the hand-operated input device is configured to operate.

23 . The system of claim 22 , wherein the angle is substantially perpendicular to the planar surface.

24 . The system of claim 21 , wherein the wireless power transmitting coil is a component of a power propagation device disposed in the hand-operated input device, wherein the wireless power transmitting coil is a first wireless power transmitting coil.

25 . The system of claim 24 , the power propagation device further comprising a wireless power receiving coil to receive a magnetic flux from a second wireless power transmitting coil disposed at a planar surface upon which the hand-operated input device is configured to operate.
