Abstract:
The invention relates to a method for the manufacture of a planar, capacitive information carrier comprising a graphic artwork and electrically conductive areas forming a code layout wherein the graphic artwork and code layout coincide. The coincidence of the graphic artwork and code layout makes it difficult for a user of the information carrier to differentiate between the aesthetic and functional parts of the information carrier. The information carrier may also comprise inactive electrically conductive elements for further distracting the attention of said user from the functional code layout. In another aspect, the invention relates to information carrier and a method for reading out an information carrier.
Abstract:
The present invention relates to a capacitive, planar information carrier wherein vias form an electrical and/or galvanic connection between sub-areas of a first electrically conductive area being part of an electrically conductive layer on one side of the information carrier and an electrically conductive pattern on the other side of the information carrier. In another aspect, the invention relates to a method for the manufacture of an information carrier.
Abstract:
Die Erfindung betrifft ein Verfahren und ein System zur kapazitiven Identifizierung eines Behälters, der mit einer elektrisch leitfähigen Flüssigkeit gefüllt ist. Dabei wird ein Behälter oder sein Inhalt durch kapazitive Kopplung durch einen Flächensensor identifiziert.

Abstract:
The invention relates to a capacitive, planar information carrier with a first, second and third electrically conductive area wherein the first electrically conductive area is overprinted with a first dielectric layer having a first relative permittivity ε1 and wherein the third electrically conductive area is overprinted with a second dielectric layer having a second relative permittivity ε2. In another aspect, the invention relates to an information carrier formed from an electrically conductive surface of an object or an electrically conductive object. In other aspects, the invention relates to methods for the manufacture of information carriers, methods for detecting information carriers and to the use of an information carrier.
Abstract:
The invention relates to an information carrier with an enhanced capacitive contrast between the desired electrically conductive elements, i.e. the touch points, and the necessary, but interfering electrically conductive elements, i.e. the coupling area and the conductive traces. The invention also relates to a method for the manufacture of said information carrier and a use of said information carrier.
