Abstract: The disclosure relates to a motor vehicle and a method for summarizing a conversation in a motor vehicle. The method involves determining by a vehicle sensor device whether a challenging driving task is present; if the challenging driving task is present, masking a conversation in the motor vehicle for a driver by generating counter noise; recording the conversation in the motor vehicle by at least one vehicle microphone; summarizing the conversation by artificial intelligence; outputting a summary of the conversation to the driver after determining that the challenging driving task is no longer present; and deactivating the counter noise after the outputting the summary of the conversation.

Abstract: An NMR apparatus having a magnet coil system for generating a homogeneous magnetic field comprises a superconducting magnet within a vacuum vessel in the cold region of a cryostat and a shim system containing shim elements outside the vacuum vessel, wherein the magnet has a first mechanical connection point to the vacuum vessel via a magnet suspension, and the shim system has a second mechanical connection point to the vacuum vessel via a positioning element. On at least one portion of a path along the vacuum vessel from the first mechanical connection point to the second mechanical connection point and/or on at least one portion of a path along the positioning element from the second mechanical connection point to the shim system, only materials whose thermal expansion coefficient at operating temperature is less than 5 ppm/K are used. Magnetic field homogeneity can thus be kept largely stable and constant.
