  • Patent number: 11222000
    Abstract: Embodiments of the present invention provide systems and methods for visualizing and querying data. Data subsets within an original table are examined. Values within the data subsets are extracted. Based on the extracted values, a new table is generated. The data contents of the original table differ from the data contents of the new table. Thus, the resulting visualization of the original table differs from the resulting visualization of the new table.

  • Patent number: 9552822
    Abstract: An apparatus for processing an audio signal is provided. The apparatus has a signal processor and a configurator. The configurator is adapted to configure the signal processor based on configuration information such that a configurable upsampling factor is equal to a first upsampling value when a first ratio of the second configurable number of samples to a first configurable number of samples has a first ratio value. Moreover, the configurator is adapted to configure the signal processor such that the configurable upsampling factor is equal to a different second upsampling value, when a different second ratio of the second configurable number of samples to the first configurable number of samples has a different second ratio value. The first or the second ratio value is not an integer value.

  • Patent number: 8959017
    Abstract: An apparatus for encoding includes a first domain converter, a switchable bypass, a second domain converter, a first processor and a second processor to obtain an encoded audio signal having different signal portions represented by coded data in different domains, which have been coded by different coding algorithms. Corresponding decoding stages in the decoder together with a bypass for bypassing a domain converter allow the generation of a decoded audio signal with high quality and low bit rate.
