Remote energy supply process and system for an electronic information carrier
First Claim
1. An arrangement and a method for remote energy supply of an electronic information carrierby a base device comprising an acoustic transmitting unit, said information carrier including an electronic information processing unit, an energy supply unit converting mechanical energy of acoustic waves into electric energy, and an information transmitting and/or receiving unit capable of receiving and/or transmitting acoustic waves, and being arranged in an acoustically fixed coupling to a functional article, characterised in that said acoustic transmitting unit (3) of said base device (1) and said functional article (4) are arranged in a loose contact connection through a surface-bodily contact, said acoustic transmitting unit (3) of said base device (1) and said information carrier (5) do not necessarily contact each other, said acoustic transmitting unit (3) of said base device (1) radiates acoustic energy to enter said functional article (4) on a bodily path through the point of contact between said acoustic transmitting unit (3) and said functional article (4), said energy supply unit (10) of said information carrier (5), which works preferentially within the resonance range corresponding to the frequency of the entered acoustic waves, draws acoustic energy from said functional article (4), the electric energy generated by said energy supply unit (10) from the drawn acoustic energy guarantees the energy supply of said entire information carrier (5), and an information transmission is realised on a bodily-acoustic path between said functional article (4) and said base device (1) and/or another device on the part of said information carrier (5) through said information transmitting (12) and/or receiving unit (11) thereof.

Abstract
Remote energy supply process and system for an electronic information carrier. Known processes and devices do not allow supplying energy wirelessly to an information carrier arranged inside a thick-walled and/or metallic body because energy radiation based on electromagnetic waves hardly penetrates, if at all, such bodies and contactlessly transmitted ultra-sound does not effectively penetrate them. The system consists of a basis apparatus fitted with an acoustic transmission unit in loose connection by a superficial body contact with a functional object. The information carrier is located inside this functional object, in an acoustically solid connection therewith. This creates a closed, acoustically well coupled total system which ensures an effective energy and information transmission by acoustic means. The invention is applicable for the transmission of codes and information in the electronic entry/access authorization field and product identification.
