Abstract: A fastening system for attaching an NMR probe to an NMR magnet includes a discoid insert and a retention system that is rigidly connected to the magnet and on which the insert can be mounted. A form-fitting, variable-force connection is established between the NMR probe and the retention system using a spring element. The probe attaches to the insert by a plurality of integral, rigid retaining elements that are of an invariable fixed length. The spring element and the retaining elements are designed geometrically such that in a first, opened state the connection between the insert and the retaining elements has a mechanical backlash between 0.5 mm and 5 mm when the spring element is relaxed. In a second, closed state the connection between the insert and the retaining elements has no mechanical backlash when the spring element is under mechanical tension.

Abstract: A chassis controller and method for controlling the damping of a human-powered two-wheeled vehicle having a controllable shock absorber and a control device and a memory device. A sensor device acquires measurement data sets relating to a relative movement of two connecting units of the shock absorber with respect to one another. A filter device pre-processes the measurement data sets. Multiple data sets are stored in the memory device. A data set, derived from a measurement data set acquired with the sensor device during the relative movement of the connecting units is stored and an analysis device analyzes a stored data set. A filter parameter set is determined based on the analysis, and a control data set is derived with the filter parameter set. The control device controls the shock absorber with the control data set.

Abstract: A method and an assembly for absorbing energy during an overload event. An energy absorber reduces loads on an object being transported on a loading unit during a single overload event, which introduces such a high degree of energy that there is an overwhelming likelihood the object would be damaged without an energy absorber. Measurement values on the current state of the loading unit are sensed. A control device determines an overload event and a damping of the energy absorber is set to a high value after the detection of the overload event. The damping is maintained for a specified prolonged time period and controlled dependent on the measurement values during the overload event to increase the load for objects during the specified time period initially to a specified threshold load and after the specified time dependent on the measurement values detected during the overload event.

Abstract: A transport device for transporting an NMR sample to the probe head (16) of an NMR spectrometer by means of a transport system (12) is characterized in that the transport device comprises a shuttle (15) adapted for use with a transport system. The transport system is structured to transport an HR-NMR sample spinner or an NMR MAS rotor (5). The shuttle includes a locking device for the NMR MAS rotor, the locking device being formed such that the NMR MAS rotor is released by unlocking the locking device and can be transferred to and received by the NMR MAS probe head. It is therefore possible to rapidly change from NMR spectroscopy of liquids to NMR spectroscopy of solids, and vice versa, simply by exchanging the probe head, without converting the transport system.

Abstract: An energy absorber is controlled in an overload event to absorb potentially damaging energy. The energy absorber acts between a receiving unit for receiving objects for transporting and a carrier device that connects to a transporter. An absorber force can be influenced by an electrically controlled magnetic field unit. Measurement values of loads acting on the loading unit are captured sequentially and an overload event is determined if a measure derived from the measurement values exceeds a predetermined threshold value. After the onset of an overload event a prognosticated load curve of the loading unit is assessed from a multitude of measurement values captured from the onset of the overload event. A planned power flow curve for the magnetic field unit is determined and the load curve is damped time-dependent so that a planned load curve ensues which remains beneath a predetermined load limit.
