Abstract

A surface with various layers that provide wireless charging may include at least one of a top surface layer, a second layer, comprising a plurality of lights and a power grid, disposed under the top surface layer, a charging pad disposed on a portion of the power grid, and a third layer, comprising a power supply which provides power to the plurality of lights and the power grid, disposed under the second layer.

Claims

1. An apparatus, comprising:

a layer comprising a plurality of lights and a power grid; and

one or more charging pads disposed at one or more portions of the power grid, wherein the power grid is configured to receive the one or more charging pads at dynamic locations and supply power to the one or more charging pads at the dynamic locations thereby dynamically configuring wireless charging locations of an area above the layer.

2. The apparatus of claim 1, comprising a lower layer, the lower layer comprising a power supply which provides power to the plurality of lights and the power grid, wherein the lower layer is configured to provide power to the plurality of lights and the power grid via a wired power source.

3. The apparatus of claim 1, wherein the one or more charging pads comprise a plurality of removable wireless charging pads.

4. The apparatus of claim 3, wherein the lower layer further comprises an uninterrupted power supply (UPS) and a computing module configured to control the power supplied to the plurality of removable wireless charging pads.

5. The apparatus of claim 4, wherein the computing module is configured to change a color of the plurality of lights to indicate at least one of charging, not charging, and error charging.

6. The apparatus of claim 5, wherein the color of the plurality of lights changes in an area covered by the one or more charging pads.

7. The apparatus of claim 4, further comprising a further layer comprising a plurality of conduits that provide power to the UPS, the power supply and the computing module of the lower layer, the further layer being disposed under the lower layer.

8. The apparatus of claim 1, wherein the plurality of lights comprise a plurality of light emitting diodes (LEDs).

9. The apparatus of claim 8, wherein the top surface layer is transparent and permits the light from the plurality of LEDs to be visible.

10. The apparatus of claim 1, wherein the power grid comprises a plurality of nodes that each provide a fixed amount of voltage to the charging pad.

11. An apparatus, comprising:

a plurality of nodes disposed on a power grid that each provide power; and

one or more wireless charging pads, wherein the plurality of nodes are configured to receive the one or more charging pads at dynamic locations and supply power to the one or more charging pads at the dynamic locations thereby dynamically configuring wireless charging locations.

12. The apparatus of claim 11, further comprising at least one conduit which provides power to a plurality of lights and the power grid via a wired power source.

13. The apparatus of claim 11, wherein the one or more charging pads comprise a plurality of removable wireless charging pads disposed on the power grid.

14. The apparatus of claim 13, further comprising a computing module configured to control the power supplied to the one or more charging pads.

15. The apparatus of claim 14, wherein the computing module is configured to change a color of a plurality of lights to indicate at least one of charging, not charging, and error charging.

16. The apparatus of claim 15, wherein the color of the lights changes in an area covered by the charging pad.

17. The apparatus of claim 14, further comprising at least one conduit that provides power to one or more of:

a power supply and the computing module.

18. The apparatus of claim 15, wherein the plurality of lights comprise a plurality of light emitting diodes (LEDs).

19. The apparatus of claim 18, further comprising a transparent surface layer disposed over the power grid that permits the light from the plurality of LEDs to be visible.

20. The apparatus of claim 11, wherein the power of each of the plurality of nodes is a fixed amount of voltage.
