  • Patent number: 9327823
    Abstract: A device for reducing structural vibrations of airfoils in an aircraft comprises, in the region of the airfoil tips, at least one force generator acting substantially in the direction of movement of the vibrations. This arrangement has the advantage that such a force generator is considerably less susceptible to wear than conventional aerodynamic flaps and therefore effective vibration damping is possible with a reduced outlay on maintenance and greater efficiency.

  • Patent number: 9300866
    Abstract: A method for image processing involves collecting image data of a scene as electromagnetic radiation and processing the image data to improve the signal-to-noise ratio of the image data. The image processing involves dividing a raw image that contains the image data into lines and columns, to create a raster image, superimposing a central raster filter element of a raster filter having an odd number of lines and an odd number of columns onto a raster image element, determining the brightness values of each of the raster image elements covered by the raster filter, wherein except for the central raster filter element, every other raster filter element has an individual light-reducing property, and adding up the brightness values to produce a total brightness value, and assigning this total brightness value to the raster image element covered by the central raster filter element.

  • Publication number: 20150268296
    Abstract: A circuit is designed to be executed in a predeterminable operating mode of a plurality of operating modes. The circuit includes a first functional unit and a second functional unit. The first functional unit is designed as a static functional unit that in each of the plurality of operating modes of the circuit carries out a consistent function. The second functional unit is designed as an adaptable functional unit that is designed to be configured, prior to the circuit being put into service, according to a first configuration of a plurality of different configurations and during the operating time of the circuit to maintain the first configuration so that the first configuration of the second functional unit defines the predeterminable operating mode of the circuit. This makes it possible to reduce the verification expenditure for the circuit because verification can be limited to the adaptable functional unit.
