    Abstract: A device transmits a force between a chassis and a body of a rail vehicle. The device is a structurally simple, space-saving device which allows spring movements and rotational movements of the body relative to the chassis. This is achieved in that at least one first traction link buffer, which has a first end face, and at least one second traction link buffer, which has a second end face, are fixed to the chassis. The first end face is spaced from the second end face in a longitudinal direction of the rail vehicle. The two end faces point in at least approximately opposite directions, and a stop plate with sliding portions which are mutually spaced in the longitudinal direction is provided on the body. The end faces of the traction link buffers rest against the sliding portions in a slidable manner at least along some sections.

    Abstract: Apparatus, methods, and other embodiments associated with nuclear magnetic resonance (NMR) fingerprinting using echo splitting are described. One example apparatus includes an NMR logic configured to repetitively and variably sample a (k, t, E) space associated with an object to acquire a set of NMR signals. Members of the set of NMR signals are associated with different points in the (k, t, E) space. Sampling is performed with t and/or E varying in a non-constant way. The varying parameters may include the number of echo splitting pulses, spacings between echo splitting pulses, flip angle of echo splitting pulses, echo time, RF amplitude, and other parameters. The NMR apparatus may also include a signal logic configured to produce an NMR signal evolution from the NMR signals, and a characterization logic configured to characterize a resonant species in the object as a result of comparing acquired signals to reference signals.
