Abstract
A power providing system for transferring power from an inductive power outlet to an inductive power receiver. The power providing system includes a targeting apparatus capable of detecting the location of the inductive power receiver adjacent to said extended surface and driving a primary inductor in the vicinity of the inductive power receiver. Optionally, the inductive power outlet includes a moving primary inductor which may move into alignment with the receiver. Alternatively, the inductive power outlet includes an array of primary inductors and a primary inductor may be selected in the locality of the inductive power receiver.
