Patent ID: 7770443

Claim:
A power feeding arrangement for electric loads (R) mounted in tires ( 20 ) of vehicles, which arrangement comprises at least one feed coil (L f ) arranged in the vehicle ( 10 ), at least one receiver coil (L 1 -L 4 ) arranged in the tire ( 20 ), and at least one load (R) electrically coupled to the receiver coil (L 1 -L 4 ) via voltage rectifier(s) ( 31 - 34 ) characterized in that in the arrangement each receiver coil (L 1 -L 4 ) is tuned with a serial capacitor (C 1 -C 4 ) and connected to a voltage rectifier ( 31 - 34 ) whereby the DC output currents produced by each rectifier ( 31 - 34 ) flow to the load (R) via at least one receiver coil (L 1 -L 4 ).
