Patent 7675197 was granted and assigned to Auckland Uniservices Limited on March, 2010 by the United States Patent and Trademark Office.
Apparatus is disclosed for allowing an inductive power distribution system pick-up to be located at an extended distance from the system primary conductive path. The apparatus has an elongate housing (40) which has a first coil (14) at one end to receive energy from a magnetic field associated with the primary conductive path. A second coil (16) is provided at the other end of the housing and is electrically connected to the first coil to produce a magnetic field for the supply of electrical energy to the pick-up. The circuit formed by the two coils is tuned to have a desired resonant frequency.
