Wireless energy transfer
View Patent ↗Apparatus and a method are provided. One example of the apparatus comprises: a housing, defining a through-hole, configured to retain an electronic device in the through-hole; at least one coil configured to receive energy wirelessly; and an electrical connector configured to provide energy received by the at least one coil to an electronic device retained in the through-hole.
1. An apparatus, comprising: a housing having one or more walls, defining a through-hole, configured to retain an electronic device in the through-hole, wherein the housing is configured to retain the electronic device in the through-hole while leaving at least a first face and a second face of the electronic device substantially exposed; at least one coil configured to receive energy wirelessly, the at least one coil extending along at least one wall of the housing and about a peripheral surface of the electronic device that extends between the first and second faces of the electronic device; and an electrical connector configured to provide energy received by the at least one coil to an electronic device retained in the through-hole.
2. The apparatus as claimed in claim 1 , wherein the first face and the second face of the electronic device are separated by the depth of the electronic device.
3. The apparatus as claimed in claim 2 , wherein the electronic device has a length, a width and a depth, the length is greater than the depth, and the width is greater than the depth.
4. The apparatus as claimed in claim 1 , wherein the first face of the electronic device comprises an electronic display.
5. The apparatus as claimed in claim 1 , wherein the at least one coil extends along one or more walls of the housing.
6. The apparatus as claimed in claim 1 , wherein the at least one coil is arranged to coil around the through-hole.
7. The apparatus as claimed in claim 1 , wherein the housing is configured to retain an electronic device in the through-hole by gripping a periphery of the electronic device.
8. The apparatus as claimed in claim 1 , wherein the at least one coil is configured to receive energy wirelessly from a further apparatus via inductive coupling.
9. The apparatus as claimed in claim 1 , wherein the electrical connector is configured to provide energy received by the at least one coil to the electronic device in order to charge a battery of the electronic device.
10. The apparatus as claimed in claim 1 , wherein the at least one coil is positioned within a recess in the housing.
11. The apparatus as claimed in claim 1 , wherein the electrical connector is positioned to connect to a further electrical connector of the electronic device, when the electronic device is retained in the through-hole.
12. The apparatus as claimed in claim 1 , wherein the electrical connector is movable relative to at least one or more walls of the housing.
13. The apparatus as claimed in claim 1 , wherein the electrical connector is movable such that the electronic connector is connectable to an electronic device positioned outside the through-hole.
14. A method, comprising: providing a housing having one or more walls, defining a through-hole, configured to retain an electronic device in the through-hole, wherein the housing is configured to retain the electronic device in the through-hole while leaving at least a first face and a second face of the electronic device substantially exposed; providing at least one coil configured to receive energy wirelessly, the at least one coil extending along at least one wall of the housing and about a peripheral surface of the electronic device that extends between the first and second faces of the electronic device; and providing an electrical connector configured to provide energy received by the at least one coil to an electronic device retained in the through-hole.
15. The method as claimed in claim 14 , wherein the at least one coil is arranged to coil around the through-hole.
16. An apparatus, comprising: a housing having one or more walls, defining a through-hole, for housing an electronic device, wherein the housing is configured to retain the electronic device in the through-hole while leaving at least a first face and a second face of the electronic device substantially exposed; at least one coil, for receiving energy wirelessly, coiled around an electronic device housed by the housing, the at least one coil extending along at least one wall of the housing and about a peripheral surface of the electronic device that extends between the first and second faces of the electronic device; and an electrical connector configured to provide energy received by the at least one coil to the electronic device.
