Abstract: Method and data carrier for storing and reading a data code, wherein at least two information tracks of electrically conductive material are printed onto a substrate in such a way that by parallel reading of the at least two information tracks a clock signal and a data signal are determined, by means of which the data code is formed. The clock signal is here formed by logic ORing of the information tracks and the data code is determined by interpreting the information tracks taking account of the clock signal.

Abstract: The invention relates to a system and a process for storing and reading information, having a data storage medium for storing information and a reading unit for reading the information stored in the data storage medium, the data storage medium having a dielectric and the information being formed by the presence or non-presence of at least one storage electrode in the data storage medium, and the reading unit having at least one input electrode and at least one reading electrode, it being possible for the data storage medium and the reading unit to be coupled to each other, for the purpose of reading the information, in such a manner that the input electrode and the storage electrode form a first capacitor and the reading electrode and the storage electrode form a second capacitor. The reading unit also has means for generating a digital voltage jump at the input electrode and means for comparing the voltage jump occurring at the reading electrode with a reference voltage.

Abstract: The invention relates to a method and to a system for electrically coupling an information carrier to a contact element, wherein the information carrier has a conductor tract structure with a contact zone, which is embedded between two substrate layers, which are connect firmly to one another, and the contact element is brought into electrical contact with the contact zone. The information carrier is in this case first cut or stamped in such a way that the contact zone is exposed in an edge region and then the contact element is brought into electrical contact with the contact zone in this edge region.

Abstract: The invention relates to a keyboard and to a method for producing a keyboard for activating electrical switching functions, comprising: a first substrate having a first contact structure; a second substrate having a second contact structure, and; an intermediate layer that holds both contact structures at a distance from one another and enables a contacting of both contact structures when pressure is exerted upon predetermined areas of the keyboard. Both contact structures are imprinted by means of a mass printing process.
