Abstract

A system can include a power cable that includes a plug and a cord; and a power supply unit that includes wireless charging circuitry and a disk shaped body that includes a recess, a power connector disposed in the recess and a cable notch as a passage from the recess to an outer perimeter of the disk shaped body, where the power connector is electrically coupled to the wireless charging circuitry and where the plug couples to the power connector and the cord passes through the cable notch.

First claim

What is claimed is:

1. A system comprising:
a power cable that comprises a plug and a cord; and
a power supply unit that comprises wireless charging circuitry and a disk shaped body that comprises a recess, a power connector disposed in the recess and a cable notch as a passage from the recess to an outer perimeter of the disk shaped body, wherein the power connector is electrically coupled to the wireless charging circuitry and wherein the plug couples to the power connector and the cord passes through the cable notch.

2. The system of claim 1 , wherein the power supply unit comprises a first arrangement of magnets for magnetic coupling to a second arrangement of magnets of a device.

3. The system of claim 2 , comprising the device.

4. The system of claim 3 , wherein the device comprises a display side and a back side, wherein the second arrangement of magnets is located at the back side.

5. The system of claim 4 , wherein the device comprises a connector and wherein the plug of the power cable couples to the connector.

6. The system of claim 3 , wherein the device comprises a display side, a back side, and a panel hinged to the back side.

7. The system of claim 6 , wherein the panel comprises the second arrangement of magnets.

8. The system of claim 7 , wherein a magnetic attraction force between the first arrangement of magnets and the second arrangement of magnets exceeds a gravity force of a mass of the power supply unit.

9. The system of claim 1 , comprising a stand, wherein the stand is attachable to the power supply unit.

10. The system of claim 9 , wherein the stand comprises a recess that receives at least a portion of the power supply unit.

11. The system of claim 9 , wherein the stand covers the recess of the power supply unit.

12. The system of claim 11 , wherein the plug of the power cable is inaccessible.

13. The system of claim 9 , wherein the stand comprises a stand cable notch wherein the cord passes through the stand cable notch.

14. The system of claim 9 , wherein the power supply unit comprises a recess side and an opposing side, wherein stand covers the opposing side.

15. The system of claim 14 , wherein the recess is exposed and the plug of the power cable is accessible.

16. The system of claim 9 , wherein the stand comprises a processor and memory accessible to the processor.

17. The system of claim 1 , comprising a turntable.

18. The system of claim 17 , wherein the turntable is rotatable without rotation of the recess.

19. The system of claim 17 , comprising a stand, wherein the stand is attachable to the turntable.

20. The system of claim 19 , comprising a display device coupled to the stand.
