Universal electrical interface for providing power to mobile devices
First Claim
1. A wireless power delivery system comprising:
- a wireless power interface having a support surface and at least a single positive electrode strip and at least a single negative/ground electrode strip generating a predetermined voltage potential when operating;
at least one receiver device to be placed on said support surface having a first contact and a second contact, said first contact and said second contact physically spaced apart to permit separate connections for said first and said second contacts to said single positive electrode strip and said single negative/ground electrode strip; and
,a mechanical constraint system that at least partially constrains said at least one receiver orientation such that said first and said second contacts of said at least one receiver are oriented to be in contact with said single positive electrode strip and said single negative/ground electrode strip such that said predetermined voltage potential of said wireless power interface is applied between said first and said second contacts.

Abstract
A charging system that comprises circuitry adapted to devices to be charged, including a power receiver module embedded in or molded into a form-fit case, e.g., gel-skin, that attaches physically and electrically to the device to be charged and that effectively receives power conductively from a power delivery surface of a recharging pad on which the devices are placed. An embodiment may include a method or device whereby a simplified, common interface provides power to mobile devices via electrical contact for a range of positions and orientations of the mobile device. In some embodiments, the range of positions may be automatically partially constrained mechanically such that power is transferred for all possible remaining orientations.
