Abstract: The invention relates to a sensor system for recording a hand vein pattern. The sensor system comprises a first light source, which is designed to emit, during operation, electromagnetic waves in the near infrared range, which are able to be reflected by veins in a hand, over the entire surface, a camera having a camera chip for recording reflection signals for electromagnetic waves and for delivering image data that correspond to the reflection signals, a topography sensor for sensing three-dimensional topographies and a first processor unit, which is connected to the camera chip and to the topography sensor. The first processor unit is designed to generate from the image data from the camera and the three-dimensional topography data from the topography sensor, during operation, a normalized vein pattern for a hand or a feature vector that corresponds to the vein pattern.

Abstract: A method for performing homogeneous immunoassay formats with electrochemical detection in solution includes combining two different conjugates as reagents with a sample or a sample/buffer mixture, one conjugate including a redox marker and an analyte molecule and the second conjugate including an anti-redox marker antibody or a specifically binding fragment thereof and a molecule specifically binding the analyte.

Abstract: The miniaturized mobile radio receiver has a straight dipole antenna whose wires run along the edge of the printed-circuit board(s) of the radio receiver and are connected at their outer ends to conductive areas. The conductive strips on the circuit board(s) which run parallel to the antenna constitute a resistive-capacitive shunt and are, therefore, open in the vicinity of the antenna base to block the flow of RF signals.
