  • Publication number: 20230154475
    Abstract: An apparatus for decoding data segments representing a time-domain data stream, a data segment being encoded in the time domain or in the frequency domain, a data segment being encoded in the frequency domain having successive blocks of data representing successive and overlapping blocks of time-domain data samples. The apparatus includes a time-domain decoder for decoding a data segment being encoded in the time domain and a processor for processing the data segment being encoded in the frequency domain and output data of the time-domain decoder to obtain overlapping time-domain data blocks. The apparatus further includes an overlap/add-combiner for combining the overlapping time-domain data blocks to obtain a decoded data segment of the time-domain data stream.

  • Publication number: 20220036744
    Abstract: This invention discloses a system to automate a non-destructive test (NDT) for measuring stress or stress change developed within an object during a certain time period by using unmanned aerial vehicles (UAV) and ultrasound technique. The system comprises a ground control station (GCS), UAVs and reference positioning modules as its basis. Given a test plan containing test points over a surface of a test object in 3D point coordinates, UAVs can fly autonomously to the points and perform ultrasound measurements on them with a single or a plurality of ultrasound transducers in an automated manner. Moreover, after receiving trigger signals from the GCS, a UAV can also perform the flight and the measurement synchronously with other UAVs. After a measurement, an acquired ultrasound echo signal is taken with another echo signal acquired at a different time point to compute stress or stress change.

  • Patent number: 10984810
    Abstract: An audio decoder provides a decoded audio information on the basis of an encoded audio information including linear prediction coefficients (LPC) and includes a tilt adjuster to adjust a tilt of a noise using linear prediction coefficients of a current frame to acquire a tilt information and a noise inserter configured to add the noise to the current frame in dependence on the tilt information. Another audio decoder includes a noise level estimator to estimate a noise level for a current frame using a linear prediction coefficient of at least one previous frame to acquire a noise level information; and a noise inserter to add a noise to the current frame in dependence on the noise level information provided by the noise level estimator. Thus, side information about a background noise in the bit-stream may be omitted. Methods and computer programs serve a similar purpose.

  • Patent number: 8804970
    Abstract: An audio encoder has a common preprocessing stage, an information sink based encoding branch such as spectral domain encoding branch, a information source based encoding branch such as an LPC-domain encoding branch and a switch for switching between these branches at inputs into these branches or outputs of these branches controlled by a decision stage. An audio decoder has a spectral domain decoding branch, an LPC-domain decoding branch, one or more switches for switching between the branches and a common post-processing stage for post-processing a time-domain audio signal for obtaining a post-processed audio signal.
