Patent ID: 8164215

Claim:
A system for contactless data and power transmission between a first vehicle component and a seat or a Passenger Service Unit (PSU), comprising: at least one first control unit with a voltage input port, a data input port and a signal output port, at least one second control unit with a signal input port, a data output port and a voltage output port, and a plurality of primary windings distributed on the first vehicle component, the primary windings being distanced to one another with a corresponding plurality of first cores, at least one secondary winding in at least one second core at the seat or the PSU, the at least one secondary winding forming at least one transducer with one of the plurality of primary windings, wherein the primary windings are connectable to the signal output port of the first control unit, and the at least one secondary winding is connectable to the signal input port of the second control unit, the first control unit is adapted to generate an alternating voltage at the signal output port, from an electrical voltage present at the voltage input port, with the frequency of said alternating voltage being modulated depending on the data that is input at the data input port, the second control unit is adapted to demodulate the frequency-modulated alternating voltage present at the signal input port to extract and provide the data at the data output port, and to provide at the voltage output port a voltage that has been prepared for use in an electrical consumer, and wherein the seat or the PSU is selectively positionable relative to the first vehicle component such that at least one secondary winding arranged in the seat or the PSU is arranged so as to be adjacent to at least one primary winding for forming a magnetic circuit.
