  • Patent number: 10646447
    Abstract: The present invention relates to an oral sustained-release triple layer tablet, more particularly, a triple layer tablet consisting of an inner immediate-release layer containing a pharmaceutically active ingredient and two outer layers containing swellable polymers. Upon exposure to aqueous media, the two outer layers swell to form gelled layers surrounding the lateral side of the inner layer rapidly, thereby control effectively the release of the pharmaceutically active ingredient from the inner immediate-release layer.

  • Patent number: 10276116
    Abstract: A digital-to-analog converter may include a converting unit and a distributing unit. The converting unit may generate a first analog signal set based on less-than-all bits of an image data set in a first period and may generate a second analog signal set based on all bits of the image data set in a second period. The all bits may include at least 2 bits. The distributing unit may include output terminals, may distribute the first analog signal set to the output terminals in a first sequence in the first period, and may distribute the second analog signal to the output terminals in a second sequence. The second sequence may be opposite to the first sequence.
