INDUCTIVE POWER SUPPLY
First Claim
1. A wireless power supply system for wirelessly supplying power to a remote device comprising:
- a power supply circuit;
a primary electrically coupled with said power supply circuit, said primary capable of generating an electromagnetic field in response to power supplied by said power supply circuit;
a wireless power supply surface, said surface disposed within said electromagnetic field and adapted to support a remote device within said electromagnetic field;
a movable carrier mounted adjacent said surface, said primary carried by said carrier; and
a control for manually adjusting the position of said carrier and consequently said primary with respect to said surface, whereby said primary may be selectively moved into improved alignment with a secondary in a remote device placed on said surface to provide improved coupling between said primary and the secondary.

Abstract
In one aspect, the present invention provides a wireless power supply having a plunger for mechanically interconnecting a remote device with the power supply. The plunger may be extendable/retractable to interfit with the remote device. In a second aspect, the present invention provides a wireless power supply with a movable primary that allows for close alignment between the primary and the secondary when the remote device is disposed within a range of different positions with respect to the charging surface. The movable primary may, for example, be coupled to the remote device by a peg, a plunger or a magnet. Alternatively, the position of the movable primary may be adjusted manually. In a third aspect, the present invention provides a charging bowl having a plurality of charging stations disposed about a common axis. Each charging station may include a movable primary that permits some freedom in positioning of the remote device on the charging surface. In a fourth aspect, the present invention provides a wireless power supply having a manually movable primary.
