  • Publication number: 20210308495
    Abstract: A face mask system is provided that includes a face mask and an indicator. The indicator is arranged with the face mask. The indicator may be configured to indicate the face mask is no longer recommended for use following a first level of exposure of the face mask to ultraviolet light. In addition, or alternatively, the indicator may be configured to change its appearance when a first number of treatment cycles have been performed on the face mask using the ultraviolet light. In addition, or alternatively still, the indicator may be configured to visually indicate a mechanical property of the face mask is preserved following another level of exposure of the face mask to the ultraviolet light.

  • Patent number: 10661556
    Abstract: A display device which is connected, in data terms, to a printing press, is controlled. A depiction of a printed image, which is printed onto a printing material by the printing press, together with a plurality of ink zones, arranged next to one another transversely, with respect to a transport direction of the printing material which is guiding through the printing press, of at least one inking unit, which is arranged in the printing press, are indicated on a display surface of the display device of a control unit in a controlled manner. The inking zones are indicated by way of parallel boundary lines, which delimit them in each case.

  • Patent number: 10525697
    Abstract: An inspection system has a plurality of detection regions. The plurality of these detection regions of the inspection system are arranged to jointly inspect a printed sheet which has a plurality of printed regions. A first detection region is arranged to inspect a first printed region of the printed sheet and a second detection region is arranged to inspect a second printed region of the same printed sheet. A first measurement technology sensitivity is set for the first detection region and a second measurement technology sensitivity is set for the second detection region in the inspection system. The first measurement technology sensitivity and the second measurement technology sensitivity are set to be different from one another. The first measurement technology sensitivity and the second measurement technology sensitivity are set in each case either manually, by the use of an operating element, or automatically by the use of a program.

  • Publication number: 20190079658
    Abstract: A photographic image captured by a camera of an inspection system is manipulated. The photographic image captured by the camera is optically displayed on a screen which is a controller and a touch-sensitive screen surface. The controller displays a position-variable operating element with a mounting device on the screen. An object, with an object surface area with less than one millimeter square, is selected on any position and photographic image displayed on the screen, such that the marking device of the operating element is positioned at the position of the selected image by changing the position of the operating element. The control which is triggered by the positioning process of the marking device of the operating element, activates a manipulation tool. The selected object is manipulated independently of the rest of the photographic image displayed on the screen by use of the manipulation tool.
