Abstract: A magneto resistive memory contains first switches, a word line voltage source generating a word line voltage connected to the first switches, a line node, second switches, and cells formed of cell resistors each having a first terminal connected to the word line voltage through one of the first switches and a second terminal connected to the line node through one of the second switches. A reference resistor is connected to the line node and a reference voltage source is connected to the reference resistor. The reference resistor with the reference voltage source brings about a reduction in a respective cell current, flowing from the line node, by an average current. A device is connected to the line node and evaluates the cell resistors. The device has an amplifier for converting a difference between the respective cell current and the average current into a voltage functioning as an evaluation signal.

Abstract: The invention relates to a label identification system comprised of a transmitting-receiving unit and of identification labels on which the identification information is stored in the form of a digital identification information word. The provision of a circuit on the identification label in the form of a circuit arrangement, which is prefabricated using a polymer technique and on which the identification information is subsequently placed by the offset printing of conductor tracks, enables the provision of an identification label involving a minimal consumption of energy during inexpensive mass production. The bulk of the identification information processing is transferred to the transmitting-receiving unit.

Abstract: Sensor elements are arranged in a hexagonal grid. A processor element in the form of a primitive automaton is assigned to each of the sensor elements in the grid. The processor elements are set up to perform algorithms which enable lines of a fingerprint to be simplified such that characteristic minutiae of the fingerprint (endings and branchings of the lines) can be extracted. The processor elements are embodied using CMOS/Neuron MOS threshold value logic or using CMOS/NMOS pass transistor logic. The image grid can be read out via read-out circuits as a matrix.

Abstract: The invention relates to a circuit arrangement, a sensor array and a biosensor array. The circuit arrangement comprises a substrate, a sensor element configured on a surface area of the substrate with a physical parameter which can be coupled to a substance to be analyzed; The type of coupling comprises a resistive component and a calibrating device embodied in or on the substrate and arranged in such a way that a modification of the value of the physical parameter of the sensor element can be at least partially compensated therewith. Preferably, the sensor element of the circuit arrangement is provided with an electrically conductive sensor electrode which can be coupled to the substance to be analyzed. The sensor element can also comprise a measuring transistor with a gate connection which is coupled to the electrically conductive sensor electrode.

Abstract: The invention relates to a measuring cell for receiving an electric potential of a sample. Said cell has a common substrate for a sensor, which converts a sample into an electric potential and for an amplifier circuit, which is connected to the sensor. The measuring field contains several measuring cells. The measuring cell can also be used to subject a sample to an electric potential, by applying an electric signal to the amplifier circuit.
