Abstract

Disclosed herein are a number of embodiments for wireless and non-conductive transfers of power and data to electronic devices. These technological advances can be implemented in retail security products (e.g., merchandising display positions for devices such as smart phones, tablet computers, wearables (e.g., smart watches), digital cameras, etc.) as well as docking systems for tablet computers.

First claim

What is claimed is:

1. An apparatus comprising:
a base position assembly that includes a wireless power transmitter, a first wireless data transceiver that outputs wireless data as radio frequency signals, and a first lens;
an intermediary assembly for use with an electronic device, the intermediate assembly having a wireless power receiver, a second wireless data transceiver, and a second lens; and
a plastic conduit located between the second wireless data transceiver and the second lens,
wherein the wireless power transmitter provides wireless and non-conductive power transfer to the wireless power receiver, the first lens and the second lens focus the wireless data output from the first wireless data transceiver into the plastic conduit that directs the wireless data to the second wireless data transceiver, and the intermediate assembly transfers the power and the wireless data to the electronic device.

2. The apparatus of claim 1 wherein the wireless power transmitter comprises an inductive transmit coil for inductive power transfer over the interface.

3. The apparatus of claim 1 wherein the wireless data transceiver comprises a near field communication (NFC) transceiver.

4. The apparatus of claim 1 wherein the intermediate assembly includes a surface on which the electronic device can be rested, and wherein the intermediate assembly transfers power and data to the electronic device via a connector cable.

5. The apparatus claim 4 wherein the base position assembly further comprises a second plastic conduit between the wireless data transceiver and the surface, wherein the second plastic conduit propagates the wireless data to the first lens.

6. The apparatus of claim 1 wherein the wireless power transmitter comprises a plurality of inductive coils that are spaced to provide for wireless power transfer through multiple regions of a surface of the base position assembly.

7. The apparatus of claim 1 wherein the wireless data transceiver comprises a plurality of wireless data transceivers that are spaced to provide for wireless data transfer through multiple regions of a surface of the base position assembly.

8. A system comprising:
a base position assembly that includes a wireless power transmitter, a first wireless data transceiver that outputs first wireless data as radio frequency signals, and a first plano-convex lens; and
an intermediary assembly for use with an electronic device, wherein the intermediary assembly includes a wireless power receiver, a second wireless data transceiver that outputs second wireless data in radio frequency signals, and a second plano-convex lens;
wherein the wireless power transmitter defines a wireless and non-conductive interface to wirelessly transfer power to the wireless power receiver via the interface; and
wherein the first plano-convex lens and the second plano-convex lens are positioned with a planar surface of the first plano-convex lens adjacent to a planar surface of the second plano-convex lens to form a convex-convex lens that directs transmission of the first and second wireless data between the first wireless data transceiver and the second wireless data transceiver.

9. The system of claim 8 wherein the wireless power transmitter comprises an inductive transmit coil for inductive power transfer, and wherein the wireless power receiver comprises an inductive receive coil for inductive power transfer.

10. The system of claim 8 wherein the first and second wireless data transceivers comprise near field communication (NFC) transceivers.

11. The system of claim 8 wherein the base position assembly includes a surface on which the intermediary assembly and the electronic device can be rested, and wherein the wireless power transmitter and the first wireless data transceiver are configured to wirelessly transfer power and data to the intermediary assembly in a rest position on the surface.

12. The system of claim 11 wherein the base position assembly further comprises a conduit between the base position assembly's extremely high frequency NFC transceiver and the surface, wherein the conduit propagates the wireless data through the interface.

13. The system of claim 11 wherein the intermediary assembly includes a surface that contacts the base position assembly surface when the intermediary assembly and the electronic device are in the rest position, and wherein the intermediary assembly further comprises a plastic conduit located between the second wireless data transceiver and the intermediary assembly surface, wherein the plastic conduit propagates the first and second wireless data between the first wireless data transceiver and the second wireless data transceiver.

14. A method comprising:
inductively charging an electronic device over a wireless and non-conductive interface between a wireless power transmitter located in a base position assembly and a wireless power receiver located in the electronic device or an intermediary assembly; and
wirelessly communicating wireless data as radio frequency signals over a wireless and non-conductive interface between a first wireless data transceiver located in the base position assembly and a second wireless data transceiver located in the electronic device or the intermediary assembly, wherein the wireless and non-conductive interface includes a plastic conduit and a convex-convex lens, the convex-convex lens directing transmission of the wireless data within the plastic conduit between the first wireless data transceiver and the second wireless data transceiver.

15. The method of claim 14 wherein the base position assembly is part of a retail security position for merchandising the electronic device to customers.

16. The method of claim 14 wherein the base position assembly is part of a docking system for the electronic device.

17. The method of claim 14 wherein the wireless power transmitter comprises a first inductive coil, wherein the wireless power receiver comprises a second inductive coil, and wherein the inductively charging includes inductively coupling the first and second inductive coils.

18. The method of claim 14 wherein the first wireless data transceiver comprises a first extremely high frequency (EHF) near field transceiver, and wherein the second wireless data transceiver comprises a second EHF near field transceiver.

19. The method of claim 18 wherein the electronic device or intermediary assembly comprises a wireless signal conduit, and wherein the wirelessly communicating data comprises propagating a wireless data signal between the first and second EHF near field transceivers via the conduit.

20. The method of claim 14 wherein the wirelessly communicating data comprises focusing the wireless data signal to the second second wireless data transceiver via the convex-convex lens.
