In the event of a malfunction, the first adjusting cylinder moves to the bolted operating state and the second adjusting cylinder moves to the released operating state.

Abstract: A system for coupling a first train coach to a second coach includes a first automatic coupler mountable at an end of the first coach, providing for a mechanical coupling to a second automatic coupler mountable at the second coach. The first coupler has a first coupling actuator that drives a first locking mechanism between locked and unlocked states. A first bellows has a first mounting frame, first coupling frame, and first latching mechanism at the first coupling frame. The first coupling frame is coupled by the first latching mechanism to a second coupling frame of the second bellows. A controller receives an uncoupling instruction, generates an uncoupling signal and sends it to the first coupling actuator, receives a coupling instruction, and generates a coupling signal and sends it to the first coupling actuator.

Abstract: A lidar device having an integrated optics that has a beam deflecting unit having an optical phase array that has a multiplicity of antennas that are set up to emit electromagnetic radiation at a prespecified angle of radiation. The angle of radiation covers a prespecified field of view of the lidar device. The angle of radiation has a first angle of radiation subregion, in which electromagnetic radiation is emitted having a polarization A, and has a second angle of radiation subregion, in which electromagnetic radiation is emitted having a polarization B.

Abstract: A telescoping jib of a mobile crane having a basic box and a plurality of inner boxes that can each be extended from a retraction position to an extension position and that can be locked and unlocked together in the respective retraction position or extension positions by means of bolting holes, which are arranged in the basic and inner boxes, and associated locking bolts. In order to provide a telescoping jib of a mobile crane which can be easily unlocked in an emergency, it is proposed that, in the retraction position of the basic and inner boxes, the bolting holes for the extension positions are aligned with one another.

Abstract: A telescoping jib system of a mobile crane having a basic telescoping jib and an additional telescoping jib that can be retracted and extended via a telescoping cylinder with a securing and locking unit. In order to improve the telescoping jib system, it is proposed that a securing unit is arranged on a tip of the telescoping cylinder, the securing unit comprises exclusively at least one driving bolt, via which an additional telescoping jib separate from the basic telescoping jib can be retracted into the basic telescoping jib. The invention also relates to a method for lengthening a basic telescoping jib of a mobile crane by means of an additional telescoping jib to form a telescoping jib system.

Abstract: A sensor arrangement for indirect detection of a torque of a rotatably mounted shaft includes a sensor with at least one sensor element arranged in the surroundings of a bearing of the shaft. The bearing is linked to a supporting structure. The sensor element is configured to detect a proportion of a bearing force acting in a predetermined direction. The torque of the shaft is configured to be calculated from the acting proportion of the bearing force. The sensor has at least one sensor body with an outer contour that supports a corresponding sensor element and is pressed into a receiving hole. The sensor element has a predetermined distance and a predetermined angle to the bearing.

Abstract: An induction module with integrated exhaust gas recirculation may include a housing defining a housing interior and having a first housing wall with at least one air inlet for conducting fresh air into the housing interior and a second housing wall with at least one fluid outlet. A charge-air cooler may be arranged in the housing interior. A mixing chamber may define at least part of the housing interior and may be delimited by the charge-air cooler and the second housing wall. An exhaust line may be arranged in the mixing chamber having at least one exhaust gas outlet that may be in fluid communication with the mixing chamber. The charge-air cooler and the exhaust line may be arranged in the housing such that the exhaust gas communicated into the mixing chamber may bypass the charge-air cooler.

Abstract: The invention lies in the field of optical metrology and related to optical coherence tomography (OCT). In particular, the invention relates to an apparatus and a method for the depth-dependent adaptation of the dynamic range of an OCT system to the profile of the backscattered power to be measured. The dynamic range of the measuring method can therefore be decoupled from the dynamic range of the analog/digital converter used. The invention is used, in particular, in the characterization of strongly scattering or strongly absorbing biological or technical samples.
