Abstract: An electromagnetic compatibility filter arrangement (100) for connecting to output terminals (202A-202C) of an electric converter (210), such as of a frequency converter or an inverter. The electromagnetic compatibility filter arrangement (100) includes a plurality of electro-magnetic compatibility filter devices (101A-101C). Each one of the devices (101A-101C) has a circuit board (11), a first connection element (16) in the circuit board (11) for providing electrical connection to an output terminal (202A-202C) of the electric converter (210), a first connector (14) for connecting to another of the plurality of electromagnetic compatibility filter devices (101A-101C), and at least one capacitor (12) arranged in the circuit board (11) and being electrically connected between the first connection element (16) and the first connector (14).

Abstract: The present disclosure is directed at an AC drive for driving an electric motor. The AC drive has a 3-phase diode bridge, an inverter and a snubber board with multilayer printed circuit board elements, wherein the power lane in every layer of every element is connected to only one potential DC- or DC+, each element includes two capacitors of inverted polarity, wherein each element includes two C-shaped bus bars and wherein the C-shaped bus bars of two neighbouring elements are placed in close proximity to each other.

Abstract: A biopsy needle (100) comprises a cannula (5) with a distal end (15), an inner needle (1) that has a sharpened distal end (16) and at least one biopsy cavity (7) that is located at a distance (L3) from the sharpened distal end (16). The cannula (5) and the inner needle (1) are configured so that the inner needle (1) is accommodated inside the cannula (5) and the inner needle (1) and the cannula (5) are movable with regard to each other. The inner needle (1) further comprises at least two measuring electrodes (1, 4; 3, 4) for measuring a bioimpedance spectrum, the measuring electrodes (1, 4; 3, 4) defining a measuring volume that is localized to the distal end (16) of the inner needle (1).

Abstract: The objective of the invention is to make the use of a cannula belonging to a bioimpedance sensor easier in a medical procedure after defining the bioimpedance.
