Abstract: The invention relates to a method and corresponding devices for monitoring the attention of an operator of an X-ray inspection system for nondestructive inspection of inspection objects and for ensuring the presence and/or attention of an operator of the X-ray inspection system including the following steps: display of a piece of information that defines a randomly determined desired input; detection of an actual input of the operator as a response to the displayed desired input; and, based on the desired input and the actual input, determination of a signal that indicates the attention of the operator.

Abstract: A composite component (110) for a vehicle seat (1), in particular a motor vehicle seat, having a plurality of fabric layers (116) of a fiber material and a matrix material (118) fixing the fabric layers (116). The outer component contour of the composite component (110) is at least in some sections formed by a fabric strand (125) embedded into the matrix material (118). A vehicle seat (1), in particular a motor vehicle seat, includes a composite component, in particular with a backrest structure (110) designed as the composite component.

Abstract: A bus node, a communication unit, which can be coupled for communication to at least data line of a bus; having a bus node controller, which is coupled operationally to the communication unit; and having an identification unit, which has a quadripole connectable, instead of a direct connection, between an IDT input and an IDT output for an identification line and vice versa, the quadripole being configured such that upon a serial interconnection of a first bus node with at least one second bus node for the bus node controller, the position of the first bus node is identifiable on the basis of a comparison of the voltage at the IDT input with a predetermined threshold value, regardless of the number of second bus nodes.

Abstract: The invention relates to a fiber composite with a fibrous material for reinforcement and a matrix material consisting essentially of shellac. The invention also relates to a process for producing a fiber composite with the steps:dissolving the shellac in a solvent,impregnating the fibrous material,heating the impregnated fibrous material andcompressing the impregnated fibrous material and simultaneously curing the matrix material.The production process is alternatively characterized by the steps:dissolving the shellac in a solvent,obtaining a solid by removing the solvent,pulverizing the solid,working the pulverized solid into the fibrous material,heating the fibrous material mixed with the pulverized solid, in the process of which the solid softens and permeates the fibrous material, andcompressing the permeated fibrous material and simultaneously curing the matrix material.
