  • Publication number: 20210317815
    Abstract: A wind turbine rotor blade extension fitting element, which extension fitting element is designed as a rotor blade rib with a recess and which can be pushed onto the rotor blade tip of a rotor blade to be extended, in such a way that the rotor blade tip protrudes through the recess and contacts the circumferential surface of the recess in an positive-locking manner. The extension fitting element has, on its outer circumference, an outer circumferential surface onto which a shell-like rotor blade extension can be pushed in an positive-locking manner. A core of the extension fitting element has slits and/or boreholes which, for stabilization, are filled with a material that has a higher strength and/or stiffness than the material of the core. In this way, the extension fitting element is strengthened for the transfer of high loads.

  • Patent number: 11146804
    Abstract: A video data stream is rendered reducible in a manner so that the reduction leads to a restriction of pictures of the reduced video data stream to merely a predetermined subarea of the pictures of the original video data stream and in a manner so that transcoding, such as re-quantization, may be avoided and a conformance of the reduced video data stream relative to the codec underlying the original video data stream be maintained. This is achieved by providing the video data stream with information including an indication of the predetermined subarea and replacement indices for redirecting the indices included by the payload portion so as to refer to, and/or replacement parameters for adjusting the first set of coding parameter settings so as to result in, a second set of coding parameter settings.

  • Patent number: 11137365
    Abstract: The invention relates to an assembly and a method for measuring electrical and dielectric properties of a material having dielectric properties which vary over time, with a sensor that generates an electrical field interacting with the material and which is connected indirectly or directly to a signal generator. The signal generator generates an excitation signal that can be applied to the sensor which is able to generate a sensor signal depending on the electrical and dielectric properties of the material. An analog-digital converter converts the excitation signal and the sensor signal or analog signals derived therefrom into a digital excitation signal and digital sensor signal which can be supplied to a processor-based evaluation unit. The signal generator generates a multifrequency signal with a predetermined bandwidth as the excitation signal.
