  • Patent number: 9245400
    Abstract: A sensor for checking value documents is arranged to carry out a self-test for testing its functionality. The sensor in the self-test reacts to at least one malfunction that is ascertained during the self-test and hinders the check of the value documents by the sensor automatically employing for checking the value documents, instead of the operating mode provided for checking the value documents. A modified operating mode employs at least one other measured value of the sensor for checking the value documents than is determined in the operating mode provided for checking the value documents. In contrast to the hitherto customary function failure of the sensor, the sensor can continue being operated for checking the value documents despite the malfunction.

  • Patent number: 9213438
    Abstract: An optical touchpad including a prism having a four-sided cross section including a light entry interface, a light exit interface, a touch interface and a back interface substantially parallel to and spaced apart from the touch interface. Collimated light enters the prism through the light entry interface, is reflected from the touch interface by total internal reflection, and exits the prism through the light exit interface. A first image sensor detects the collimated light exiting from the light exit interface and a second image sensor detects the image of an object positioned over the touch interface.

  • Patent number: 9001318
    Abstract: A method carries out a soiling check of the measurement window of a measuring device for checking sheet material. A measuring device carries out the method. A device for processing a sheet material comprises the measuring device. The soiling check uses, only areas of the measurement window which correspond, in terms of width and position in the beam path of a light, to the areas of the checked sheet material which are checked during the checking of the sheet material. As a result, fewer cleaning steps are needed for the measurement window.

  • Patent number: 8982178
    Abstract: The present invention provides a method and device for acquiring real-time video images of a terminal, sad method comprising: acquiring light intensity of an existing environment when the terminal acquires the real-time video images; comparing the light intensity of the existing environment with a light intensity threshold value set by the terminal system; acquiring images preset by the terminal and sending the preset images to an existing receiver which is communicating with the terminal if the light intensity of the existing environment is lower than the light intensity threshold value set by the terminal system. The present invention can ensure the quality of video conversation when the light intensity is weak, save power energy, improve the user experience, and is beneficial to promote the video communication terminal.

  • Patent number: 8766222
    Abstract: The invention relates to an apparatus and a method for checking the usage state of a document of value. The document of value is illuminated with illumination light and with the help of an image sensor there is detected the light intensity of the light reflected from the document of value in order to take an image of the document of value. Of the taken image there is chosen an image detail in which there is imaged an opaque, reflective section of the document of value. The chosen image detail is examined for signs of creases which are possibly present in the opaque, reflective section of the document of value. The results of the examination for creases are used to evaluate the usage state of the document of value.

  • Patent number: 8588477
    Abstract: A method for detecting color transitions in at least one portion of a document of value by determining for each image elements whether color coordinate values in the color space that are allocated to the image element correspond to a reference color distribution, which is given by at least one predetermined, closed reference surface in the color space, that is given by at least one linear segment predetermined for the document of value and a predetermined distance of the points of the reference surface from the at least one linear segment. The method further has the steps comparing the positions of the image elements whose color coordinate values are disposed inside or outside of the reference surface to predetermined reference positions on the document of value and detecting in dependence on the result of the comparison a presence or an absence of a color transition caused by soiling or color wear.
