Abstract:
1. An inductive power supply with magnetic attraction, said inductive power supply for transferring power wirelessly to a remote device, said inductive power supply comprising: a primary capable of transferring power wirelessly via an inductive coupling; a controller for controlling a supply of current to said primary, wherein said current includes direct current and alternating current; wherein in response to supplying said alternating current to said primary, said primary transfers power wirelessly to said remote device; wherein in response to supplying said direct current to said primary, an attractive force capable of aligning said remote device for more efficient wireless power transfer is produced; and a frictional material coupled to a first magnet, wherein said direct current supplied to said primary attracts said first magnet and causes said frictional material to retract such that said frictional material is prevented from contacting a surface of the remote device.
