  • Patent number: 10840937
    Abstract: A server utilizes a BMC to divide a video source signal into original analog and digital component signals, and stores the digital component signal in a set of registers of a duplicator. An ADC converts the original analog component signal into a converted digital component signal, which is stored in another set of registers of the duplicator. A switch set of the duplicator is switched to output a pair of the converted and the original digital component signals. One DAC converts the converted digital component signal into a converted analog component signal, which together with the original digital component signal, serves as a duplicated video signal.

  • Patent number: 10777162
    Abstract: A display apparatus includes a display panel, a timing controller, a data driver and a voltage generator. The display panel includes a switching element, a pixel electrode connected to the switching element, a common electrode, a storage electrode and a pixel electrode. The timing controller processes input image data according to a variable frame rate and generates a data signal having a variable frame length. The data driver converts the data signal into a data voltage and outputs the data voltage to the pixel electrode. The voltage generator may apply a common voltage to the common electrode and a storage voltage greater than the common voltage to the storage electrode, and/or apply the common voltage varied according to a grayscale value of the input image data. Embodiments may reduce or obviate a display defect caused by luminance differences between frames displayed at different frame rates.

  • Patent number: 10776718
    Abstract: Machine-learning methods and apparatus are provided to solve blind source separation problems with an unknown number of sources and having a signal propagation model with features such as wave-like propagation, medium-dependent velocity, attenuation, diffusion, and/or advection, between sources and sensors. In exemplary embodiments, multiple trials of non-negative matrix factorization are performed for a fixed number of sources, with selection criteria applied to determine successful trials. A semi-supervised clustering procedure is applied to trial results, and the clustering results are evaluated for robustness using measures for reconstruction quality and cluster separation. The number of sources is determined by comparing these measures for different trial numbers of sources. Source locations and parameters of the signal propagation model can also be determined.
