Abstract: A composite structure for stab protection includes layers of flat structures placed on top of each other, and an embedding material, wherein, in at least some of the layers placed on top of each other, the flat structures of adjacent layers are offset relative to one another, the flat structures of the composite structure are at least partially embedded in the embedding material, and the composite structure includes separated connecting elements, wherein before they are separated, the separated connecting elements have connected at least some of the flat structures of adjacent layers with one another.

Abstract: A computer-aided method, system and computer program product are provided for optical testing of a rope. Such method includes: providing an image data set for at least one portion of the rope; providing target values of a pictorial longitudinal extension of the representation of wires relative to a pictorial longitudinal extension of the rope in the image data set; determining a pictorial longitudinal extension of the wires in the image data set, including adapting an estimated longitudinal extension to the image data set; determining at least one quality value using a quality norm as a function of the determined pictorial longitudinal extension of the wires and the target values of the pictorial longitudinal extension of the wires; discriminating pictorial positions within the image data set of the rope, where at least one quality value exceeds or falls below a predetermined, assigned quality threshold value; and providing the discriminated pictorial positions.

Abstract: A method and a configuration for automatically or visually detecting material defects, in particular cracks, in a workpiece, includes applying a test agent to the workpiece. The test agent contains color pigments which can be excited by using shortwave light. The workpiece is then irradiated with shortwave light from a light source, light emitted by the workpiece is detected by an observer's eye or by a detector, and the signals from the detector are evaluated by an electronic evaluation device in order to determine the material defects. The light source is associated with a first optical interference filter which selects the light emitted by the light source, as a bandpass filter, before the light impinges on the workpiece.
