Abstract: A computer-implemented method for generating training data for training an algorithm for estimating positioning variances in an imaging apparatus of an x-ray imaging system is provided. The method includes predetermining target positioning data for the imaging apparatus and calculating faulty positioning data, wherein the faulty positioning data deviates from the target positioning data by at least one predetermined positioning variance. An imaging method is simulated, in order to generate two or more simulated x-ray recordings, wherein a positioning of the imaging apparatus is simulated in accordance with the faulty positioning data. An annotated training data record is generated and stored, wherein the training data record contains two or more simulated x-ray recordings and at least one positioning variance as an annotation of the two or more simulated x-ray recordings.

A distance by which the piston is displaceable in the axial direction is at least as great as the recoil distance of the recoiling masses during a passage of a bullet through the barreled firearm.

Abstract: A device for driving mechanical safety systems. The device contains a housing in which at least one moving piston is arranged. The piston is connected to a first toothed rack and the first toothed rack is operatively connected to a pinion. A second toothed rack is arranged for movement in the housing. As a result, the second toothed rack is displaced in the opposite direction to the movement of the piston. The device has a locking lever and a shift dog. The shift dog is mounted on the second toothed rack and is arranged such that, on movement of the second toothed rack, the shift dog can actuate the locking lever. A locking bush secures the securing shaft to be driven. The locking bush is initially transferred to an unlocked position on movement of the toothed racks and is returned to a locked position on conclusion of the movement.

Abstract: The invention relates to a gun barrel mounting for a gun barrel, comprising a cradle with at least one gun mounting for mounting the gun barrel and a base part that can be connected to the gun barrel.

Abstract: The installation space dimensions of a weapon system in the tower are complied with, and a loading space diameter of a caliber-larger weapon barrel is approximately maintained in relation to the smaller caliber. The required larger loading space volume for the caliber increase is predominantly achieved by an extension of the loading space of the caliber-larger weapon barrel relative to a loading space of the caliber-smaller weapon barrel itself. Since the loading space diameter of a larger caliber remains virtually unchanged, the outer dimensions of the caliber-larger weapon barrel also remain virtually unchanged compared to the outer dimensions of the caliber-smaller weapon barrel in the region of the loading part.
