Abstract

Embodiments describe an apparatus for magnetic charging and optical data transferring. The apparatus includes an inductive transmitting coil disposed within a housing, an optically transparent window disposed at a surface of the housing and above the inductive transmitting coil, and a first optical data transfer module disposed within the housing below the optically transparent window. The first optical data transfer module may be to perform at least one of emitting optical signals through the optically transparent window or detecting optical signals passing through the optically transparent window.

First claim

What is claimed is:

1. An apparatus comprising:
a housing including a first exterior surface opposite a second exterior surface;
an inductive transmitting coil disposed within the housing and positioned proximate the first exterior surface, wherein the coil has an inner diameter;
an optically transparent window forming a portion of the first exterior surface of the housing and positioned within the inner diameter of the coil; and
a first optical data transfer module disposed within the housing and optically coupled to the optically transparent window, the first optical data transfer module configured to perform bidirectional data transfer through the optically transparent window.

2. The apparatus of claim 1 wherein the first optical data transfer module is further configured to automatically align with a second optical data transfer disposed outside of the housing by moving in a horizontal plane.

3. The apparatus of claim 2 wherein the second optical data transfer is configured to automatically align with the first optical data transfer module by moving in a horizontal plane.

4. The apparatus of claim 1 further comprising alignment magnets laterally disposed around the optically transparent window.

5. The apparatus of claim 1 wherein the optically transparent window is formed of a selectively transmissive material that is selectively transparent to at least one of infrared or ultraviolet light.

6. The apparatus of claim 1 wherein the optically transparent window includes a selectively transmissive coating, wherein the selectively transmissive coating is selectively transparent to at least one of infrared or ultraviolet light.

7. The apparatus of claim 1 further comprising a magnetic shield disposed around the first optical data transfer module.

8. A docking station for a portable electronic device comprising:
a housing including an exterior mating surface configured to interface with the portable electronic device;
an inductive transmitting coil disposed within the housing and positioned proximate the exterior mating surface, wherein the coil has an inner diameter;
an optically transparent window forming a portion of the exterior mating surface and positioned within the inner diameter of the coil; and
an optical data transfer module disposed within the housing and optically coupled to the optically transparent window such that bidirectional optical data signals can be sent from and received by the optical data transfer module.

9. The docking station of claim 8 wherein the optical data transfer module is further configured to automatically align with a portable electronic device optical data transfer disposed within the portable electronic device by moving in a horizontal plane.

10. The docking station of claim 9 wherein the portable electronic device optical data transfer is configured to automatically align with the optical data transfer module by moving in a horizontal plane.

11. The docking station of claim 8 further comprising alignment magnets laterally disposed around the optically transparent window.

12. The docking station of claim 8 wherein the optically transparent window is formed of a selectively transmissive material that is selectively transparent to at least one of infrared or ultraviolet light.

13. The docking station of claim 8 wherein the optically transparent window includes a selectively transmissive coating, wherein the selectively transmissive coating is selectively transparent to at least one of infrared or ultraviolet light.

14. The docking station of claim 8 further comprising a magnetic shield disposed around the optical data transfer module.
