Abstract

An adjustable inductive power transmission platform includes inductive power outlets embedded into adjustable modules having multiple configurations. The inductive power outlets are configured to couple with inductive power receivers to provide power to electrical loads wired thereto. The multiple configurations of the adjustable modules allow the position of the inductive power outlets to be adjusted to match the locations of inductive receivers to suit changing requirements.

Claims

1. An adjustable inductive power transmission system comprising:

at least one primary inductor configured to couple with at least one secondary inductor wired to an electrical load; and

at least one power module configured to accommodate said at least one primary inductor;

wherein said at least one power module has a plurality of configurations such that said primary inductor is positionable in a plurality of locations.

2. The system of claim 1 wherein said power module comprises at least one power dock configured to accommodate at least one primary inductor unit.

3. The system of claim 2, said power dock comprising at least one of:

a socket for releasably receiving said primary inductor unit and a clip for releasably securing said primary inductor unit.

4. The system of claim 2, said primary inductor unit comprising at least one electrical contact for connecting said primary inductor unit to a power line for providing power to said primary inductor.

5. The system of claim 2 wherein a plurality of said primary inductor units are connected in parallel to at least one power line.

6. The system of claim 2 wherein a plurality of the primary inductor units are connected to at least one power hub, said power hub for controlling power distribution to said primary inductor units.

7. The system of claim 1, comprising at least one connector for coupling said module to at least one further module.

8. The system of claim 7, wherein said connector comprises at least one of:

a mechanical connector for mechanically coupling said module to a further module, and

an electrical contact for electrically coupling said module to a second module.

9. The system of claim 1, further comprising a lid configured to cover said primary inductors thereby providing a generally smooth worktop.

10. The system of claim 1, said at least one module being configured to tile at least a portion of a work surface.

11. The system of claim 1, said module being incorporated within at least one member of a group consisting of:

horizontal platforms, table-tops, kitchen work-tops, conference tables, work benches, desks, floors and combinations thereof.

12. The system of claim 1 wherein said module comprises at least one flexible strip capable of assuming a plurality of configurations, such that said power dock is movable into the vicinity of said secondary inductor.
