An image intensifier system has an image converter tube to convert incident x-ray radiation into visible light and a digital camera system optically downstream of the image converter tube. The camera system has an image sensor to convert the incident, visible light into digital images, and an electronic image processing unit is provided for post-processing of the digital images. In such a system and a method for correcting image distortion errors that occur therein, characteristic data of a magnetic field present in the image converter tube are determined with the aid of a magnetic field probe arranged within the image converter tube or in its environment, an imaging error resulting from the presence of the magnetic field is quantitatively defined using the determined characteristic data, one or more parameters of a correction map leading to the correction of the imaging error are determined based on this, and the correction map that is established in this way is applied to the digital images in the electronic image processing unit.

Method to correct imaging errors of an x-ray image intensifier system and associated x-ray image intensifier system

An operating element having an end piece, which is arranged for connecting to a printed circuit board and a front plate. An operating lever is rotatably mounted on the end piece. The operating lever has at least one grip section and one on and/or off lever piece, which are at least partly made from a wear-resistant material. Such a design has the particular advantage that part of the operating element which performs an on and/or off lever action, the on and/or off lever piece, opposite the section of the operating element to manipulate, the handle, is at least partly made from a wear-resistant material. The complete unit is thus rendered significantly more robust without sacrificing ergonomics of the grip piece.

Operating element with on and/or off lever piece for printed circuit boards

An operating element for the engaging and extraction of planar sub-assemblies, with a display element in the operating lever, a front element for a planar sub-assembly with operating element and component support for accommodating planar sub-assemblies.

Operating lever with display element

An operating element for engaging and extraction of a planar sub-assembly with an end-piece prepared for connection to the planar sub-assembly. An operating lever rotatably mounted on the end-piece has at least one grip section and a locking element which may be displaced, in particular shifted between at least two switch positions, whereby in a first switch position, the operating lever is held in a state with the planar sub-assembly in an engaged position and in a second switch position, the operating lever is released for extraction. The operating lever has at least one combined display/switching element.

An actuating element for inserting and removing a flat module by leverage, the element having an end piece designed to be connected to a flat module. An actuating lever, which is pivotally mounted on the end piece, has at least one grip section and a locking element, which can be displaced, particularly slid between two connection positions. In a first connection position, the actuating lever retains the flat module in its inserted state and in a second connection position, the actuating lever is released to remove the module by leverage. The actuating element has a connecting element, which is activated in the first connection position of the locking element, which can be displaced into a third connection position, in which the actuating lever is retained in the first position, corresponding to the inserted state of the flat module and in which the connecting element is disconnected.

ACTUATING ELEMENT COMPRISING A LOCKING ELEMENT FOR INSERTING AND REMOVING FLAT MODULES BY LEVERAGE IN A LEAST THREE CONNECTION POSITIONS, FRONT ELEMENT FOR A FLAT MODULE, COMPRISING AN ACTUATING ELEMENT AND A SUBASSEMBLY SUPPORT FOR RECEIVING FLAT MODULES

The mounting rack contains transverse rails (1, 31), at least one front element (29), and at least one spring contact strip (10; 38). The contact strip has a retaining portion (11) for fitting on an end face (21, 22) of the transverse rail and contact springs (14) which are connected to the retaining portion and have spring limbs (15) which are angled off in a direction away from the interior of the mounting rack, such that these spring limbs (15) extend in a direction generally coincident with the longitudinal side (54) of the front element the spring movements of the spring limbs (15) are generally in the same direction as the insertion and withdrawal movements (24, 48) for the printed circuit board assembly fastened to the front element.

Shielded mounting rack for electrical printed circuit board assemblies

A mounting system for mounting plug-in modules into a module carrier is disclosed. The system comprises a plug-in and pull-out fixture, the fixture having a lever which is connected to the modules by means of an endpiece. The lever is provided with a resilient self-locking detent hook which extends in the lever's locking position behind the corresponding projection of the slot in the end piece, the slot facing downwards towards the transverse bar of the module carrier. This system allows for the insertion & removal of the modules with reduced force compared to the prior art, as well as improved ergonomic handling of the modules.
