  • Patent number: 12249114
    Abstract: The disclosure belongs to the field of visible light communication, and specifically discloses a stripe image processing method and apparatus for camera optical communication. The method includes: obtaining a stripe image data set, the stripe image data set including a stripe image sample and a stripe sequence label corresponding to the stripe image sample and a stripe-free image label; based on the stripe image sample and the stripe sequence label corresponding to the stripe image sample and the stripe-free image label, training a generative adversarial network to obtain an image reconstruction model and a stripe extraction model; among them, the image reconstruction model serves as a generator of the generative adversarial network, and the stripe extraction model serves as a discriminator of the generative adversarial network.

  • Patent number: 8685698
    Abstract: A yellow pigments generation deficient Sphingomonas strain (Sphingomonas sp. ZD001) and application thereof in preparing gellan gum by microbial fermentation are provided. The strain is preserved in China Center for Type Culture Collection (CCTCC) with the address of Wuhan University, Wuhan, 430072, China, the preservation date of the strain is 10 Sep. 2009, and the preservation serial number is CCTCC No: M 209298. The main beneficial effect of the present invention is that the fermented liquor contains no yellow pigments but is milky white, colorless superior gellan gum can be obtained by only depositing polysaccharide with a small quantity of ethanol or isopropanol, so that the post purification and de-coloration techniques of gellan gum production can be simplified, the yield can be enhanced, and the production cost can be reduced.

  • Publication number: 20130320799
    Abstract: Disclosed in the present invention is a reinforced permanent magnet synchronous motor rotor for line-start, comprising: standard laminations, conductive bars, magnetic bars, and reinforced laminations; the reinforced laminations being located between standard laminations; the magnetic bars are embedded in the standard laminations and separated by the reinforced laminations, and the conductive bars run through the standard laminations and reinforced laminations overlying one other. Comparing the structures of the reinforced permanent magnet synchronous motor rotor for line-start provided by the present invention and the permanent magnet motor rotor in the prior art, the mechanical strength of the motor rotor is increased effectively and the service life of the motor rotor is lengthened by adding reinforced laminations, under the precondition that motor efficiency is not sacrificed.
