Abstract: The invention relates to a switching apparatus (1) for conducting electrical contact tests on bare and assembled printed circuit boards (12), comprising at least a flat support layer (2), a first electrode arrangement (3) and a functional layer (4), which support layer (2) is elastically restorably deformable, and the functional layer (4) is disposed on top of the first electrode arrangement (3). The functional layer (4) is made from at least one of the group comprising a layer of a photosensitive material (7), a quantum detector and a photoresistor, and at least one source for electromagnetic radiation (8) is additionally disposed above the functional layer (7), and the emitted electromagnetic radiation predominantly acts in the direction of the functional layer (4). The functional layer (4) may also be provided in the form of a transistor arrangement (9) made up of a plurality of transistors. The invention further relates to a method of producing a switching apparatus (1).

Abstract: The invention relates to a method for publicly providing protected electronic documents, wherein a first user, after a user authentication process, transmits a private electronic document from a data terminal via a communications network to a private storage medium of a data processing device and stores the document on said medium. Thereafter, an analysis and comparison module is activated, which analyzes and compares the private electronic document to the public electronic documents in a public storage medium, and when a second user accesses the private electronic document of the first user, a public electronic document from the public storage medium is provided by the authentication and access control module instead of the private electronic document.

Abstract: The invention relates to a mobile data memory (1) comprising a data memory module (2) and a holding and/or carrying device (3), wherein the data memory module (2) has a non-volatile, re-writable semiconductor memory (4) and an access controller (5) with a communications module (7), wherein furthermore the communications module (7) is connected to a communications interface (8). The holding and/or carrying device (3) has a contact detection unit (16); the data memory module (2) furthermore has an allocation monitoring module (6) which is designed to evaluate the contact detection unit (16) and which is connected to the semiconductor memory (4) and/or to the access controller (5). The invention further relates to a method for person-based saving of information in a mobile data memory, wherein a remote communications station can access information saved in the data memory via a communications interface, and wherein a loss of the allocation of the mobile data memory to a person is detected.

Abstract: An identification device for identifying persons on an authenticated basis includes a support layer, an authentication device with a non-volatile, re-writeable semiconductor memory, a person-related feature, a communication system with a communication connector, and a first electronic key which is linked to the person-related feature and is stored in the memory. In a further aspect, an identification device for identifying persons on an authenticated basis includes an electronic data set in which an electronic image of a person-related feature and a first electronic key are stored, and the first electronic key is linked to the person-related feature. Also provided is a method of identifying and authenticating a person by an identification device.
