Abstract: A medical technology facility includes a functional component, a carrier arrangement provided so as to position the functional component in a space, at least one additional component configured to be positioned and/or formed differently in different positions of the carrier arrangement, and a control facility. In order to form a collision protection system, the control facility is configured to: update a digital movement model of the medical technology facility, wherein the digital movement model maps the carrier components and the functional component with their movability based on position data that indicates prevailing positions of the carrier components; evaluate the prevailing movement model so as to detect possibly impending collisions with at least one subject and/or object that is located in the movement region and that is mapped in the movement model; and implement at least one collision protection measure when an impending collision is detected.

Abstract: A method of processing print jobs on a printing substrate processing machine by using a computer, includes creating a data model for the computer with parameters for an unusable print/set-up time prediction on the basis of global print jobs and printing machine data, training the data model on the basis of global and/or local print jobs and printing machine data by using the computer, and defining ease-of-use criteria by an operator. The trained data model for the computer is used to predict the number of unusable prints during set up and set-up time of the printing substrate processing machine. The order of the processing of the print jobs is optimized on the basis of the predicted number of unusable prints during set-up and the predicted set-up time by using the computer.

Abstract: A method for detecting defective printing nozzles in an inkjet printing machine includes printing a multi-row printing nozzle test chart formed of horizontal rows of equidistant vertical lines periodically underneath one another, with only printing nozzles in a print head contributing to every row of the test chart corresponding to the horizontal rows. An area coverage element geometrically associated with the test chart is printed, both elements are recorded by an image sensor and analyzed by the computer. The computer analyzes the recorded area coverage element to detect print defects and allocates defects to a region of geometrically close printing nozzles. An analysis of the test chart in the region identifies nozzles causing the defect. Defective printing nozzles are detected based on thresholds, the detected printing nozzles are then compensated, and in the analysis of the recorded area coverage element, influences of the sensor are eliminated by shading correction.

Abstract: A device for printing on at least one region of a surface of a so-called 3D object, for instance a curved auto body part, includes a manipulator, for instance an articulated-arm robot with six degrees of freedom. The device also includes a system for vibration compensation for the print head. The system includes an active component and a passive component. Manipulator vibration which creates defects in a printed image may thus be effectively avoided.
