Abstract: A computer-implemented method. The method includes recognizing the possibility of a manipulation of the software of a first component of a plurality of components of a vehicle electrical system of a vehicle in a central device for mitigating a manipulation of software. The central device for mitigating a manipulation is part of the vehicle electrical system, and is designed to mitigate a manipulation of software in each component of the plurality of components of the vehicle electrical system. The method further includes initiating a countermeasure for mitigating the manipulation of the software of the first component and carrying out the countermeasure for mitigating the manipulation of the software of the first component. The countermeasure includes changing a functionality of the first component and at least partially shifting the functionality of the first component to one or multiple other components of the plurality of components.

Abstract: A local coil for a magnetic resonance apparatus, including: at least one antenna designed to receive radio frequency signals in a frequency and power range of a magnetic resonance measurement; a holding element designed to hold the at least one antenna in a position that is appropriate for application on a diagnostically relevant body region of a patient, wherein the at least one antenna is mechanically connected to the holding element; a base element, wherein a first end of the holding element is mechanically connected to the base element and wherein a second end of the holding element opposite the first end is free-floating; and a guide system that is mechanically connected to the base element and the holding element, and is designed to position the holding element variably with respect to the base element.

Abstract: An electrical drive device (1) includes a control circuit (3) connectable to a voltage source (5) on the input side and to an electric drive motor (4) on the output side. The control circuit (3) includes two separate return conductors (13, 35) connected to each other at a single connection point (36). One return conductor (13) is connected to the ground terminal (12) of the control circuit (3). The other return conductor (35) is connected to a motor converter (14), a converter control (15) and a back-up capacitor (19). Due to this arrangement, the currents (is, ia) flowing in a back-up circuit loop (31) and a control circuit loop (32) are confined to remain within the control circuit (3) and are separated from a housing (10), for example the chassis of a motor vehicle. As a result, the electrical drive device (1) has low interference emissions.

Abstract: An electric drive device (1) comprises a motor converter circuit (3) according to the invention, which includes an intermediate circuit capacitor (16). The intermediate circuit capacitor (16) comprises a parallel circuit of several ceramic capacitors (24). The ceramic capacitors (24) have a lower dissipative resistance and enable better heat removal, so that the motor converter circuit (3) has a comparatively longer service life.
