Patent ID: 7277675

Claim:
Array for the contact-less transmission of electrical signals or energy, respectively, from at least one transmitter to several receivers, characterized in that each transmitter comprises an AC voltage or current source, respectively, as well as a plurality of inductive coupling elements supplied in parallel or in series from said source, which said plurality of inductive coupling elements are supplemented by at least one capacitor to form resonance circuits whose outputs are sent to respective said receivers that equal in number to said plurality of inductive coupling elements, and that furthermore one control element controls said AC voltage or current source, respectively, in such a way that the latter operates on a resonant frequency of said plurality of inductive coupling elements configured for resonating, and wherein additional capacitive elements are provided for the transmission of additional signals, and said additional signals are transmitted via a magnetic path associated with a magnetic outside surface of the transmitter or further branches in the case of multi-branch cores, which said magnetic path is not used for the transmission of energy.
