Abstract

A charging stand is provided including a body having a first surface, and a bump having a top region and one or more sides. The one or more sides extend between the first surface and the top region. The charging stand further includes one or more base contact pins that are coupled to the body. Each base contact pin has an exposed end disposed at a first distance in a first direction from the first surface. The charging stand further includes a bump contact pin extending from the top region of the bump. The bump contact pin has an exposed end disposed a second distance in the first direction from the first surface, the second distance is greater than the first distance, and the first direction is perpendicular to the first surface.

First claim

What is claimed is:

1. A charging stand, comprising:
a body comprising a first surface;
a raised portion comprising a top region and one or more sides, wherein the one or more sides extend between the first surface and the top region;
one or more base contact pins that are coupled to the body, each base contact pin having an exposed end disposed at a first distance in a first direction from the first surface, the one or more base contact pins comprising a first contact pin and a second contact pin; and
a raised portion contact pin extending from the top region of the raised portion, wherein the raised portion contact pin has an exposed end disposed at a second distance in the first direction from the first surface, the second distance is greater than the first distance, wherein the first contact pin is electrically connected to the second contact pin, and the raised portion contact pin is electrically isolated from the first contact pin and the second contact pin.

2. The charging stand of claim 1 , wherein the one or more sides of the raised portion have a convex or concave surface.

3. The charging stand of claim 1 , wherein portions of the one or more sides of the raised portion between the first surface and the top region of the raised portion form a truncated cone.

4. The charging stand of claim 1 , wherein the exposed ends of the one or more base contact pins are disposed within a plane that is substantially parallel to the first surface.

5. The charging stand of claim 1 , wherein the one or more base contact pins are spring loaded.

6. The charging stand of claim 1 , wherein the body comprises a plastic material.

7. The charging stand of claim 1 , wherein the one or more base contact pins are electrically connected to an electrical ground.

8. A charging stand, comprising:
a body comprising a first surface;
a raised portion comprising a top region and one or more sides, wherein the one or more sides extend between the first surface and the top region;
one or more base contact pins that are coupled to the body, each base contact pin having an exposed end disposed at a first distance in a first direction from the first surface, the one or more base contact pins comprising a first contact pin and a second contact pin; and
a raised portion contact pin extending from the top region of the raised portion, wherein the raised portion contact pin has an exposed end disposed at a second distance in the first direction from the first surface, the second distance is greater than the first distance, wherein the first contact pin is electrically connected to the second contact pin, the raised portion contact pin is electrically isolated from the first contact pin and the second contact pin, the exposed end of the raised portion contact pin is not within a line of sight of the first contact pin, and the raised portion contact pin is not within a line of sight of the second contact pin.

9. The charging stand of claim 8 , wherein the one or more sides of the raised portion have a convex or concave surface.

10. The charging stand of claim 8 , wherein portions of the one or more sides of the raised portion between the first surface and the top region of the raised portion form a truncated cone.

11. The charging stand of claim 8 , wherein the exposed ends of the one or more base contact pins are disposed within a plane that is substantially parallel to the first surface.

12. The charging stand of claim 8 , wherein the one or more base contact pins are spring loaded.

13. The charging stand of claim 8 , wherein the body comprises a plastic material.

14. The charging stand of claim 8 , wherein the one or more base contact pins are electrically connected to an electrical ground.

15. A charging stand, comprising:
a power supply circuit;
a body comprising a first surface;
a raised portion comprising a top region and one or more sides, wherein the one or more sides extend between the first surface and the top region;
one or more base contact pins that are coupled to the body, each base contact pin having an exposed end disposed at a first distance in a first direction from the first surface, the one or more base contact pins comprising a first contact pin and a second contact pin; and
a raised portion contact pin extending from the top region of the raised portion, wherein the raised portion contact pin has an exposed end disposed at a second distance in the first direction from the first surface, the second distance is greater than the first distance, and the first direction is perpendicular to the first surface, wherein the first contact pin is electrically connected to the second contact pin, the raised portion contact pin is electrically isolated from the first contact pin and the second contact pin, the raised portion contact pin is not within a line of sight of the first contact pin, and the raised portion contact pin is not within a line of sight of the second contact pin;
a power supply configured to generate a first voltage between the first contact pin, the second contact pin, and the raised portion contact pin.

16. The charging stand of claim 15 , wherein the one or more sides of the raised portion have a convex or concave surface.

17. The charging stand of claim 15 , wherein portions of the one or more sides of the raised portion between the first surface and the top region of the raised portion form a truncated cone.

18. The charging stand of claim 15 , wherein the exposed ends of the one or more base contact pins are disposed within a plane that is substantially parallel to the first surface.

19. The charging stand of claim 15 , wherein the one or more base contact pins are spring loaded.

20. The charging stand of claim 15 , wherein the power supply is also configured to generate a second voltage between the first contact pin, the second contact pin, and the raised portion contact pin.
