  • Patent number: 9621883
    Abstract: The invention relates to a method and apparatus for evaluating a network and for predicting network performance for a higher order modulation by analyzing network signals modulated using a lower order modulation format. A margin index may be generated for the current or projected modulation formats based on displacement vectors for received symbols to indicate a margin remaining before a codeword error occurs to alert the network operator of potential performance issues before actual codeword errors occur.

  • Publication number: 20170017100
    Abstract: A smart flexile smart curtain film is disclosed, a light transparency for the smart curtain film can be adjusted according to a voltage applied thereon. One of the embodiment shows that the smart curtain film is designed normal dark, and the transparency is related to the voltage applied. The greater voltage is applied the more transparent the smart curtain film displays. The smart curtain film is adaptive to be attached onto a surface of a window glass to form a smart window glass. During daytime, a person can adjust the transparency of the smart curtain to block some light beams from entering the room; and vice versa, during nighttime, a person can adjust the transparency of the smart curtain to block some light beams from exiting the room to keep one's privacy.

  • Patent number: 9441191
    Abstract: A solid-state fermentation method is provided. The method is provided for edible and medicinal microorganisms. A commensurate device is used for processing sterilization, inoculation, cultivation, drying, and collection. Cultivation substrates are filled in cultivation plates and placed on trays of a movable layer rack in a reaction fermenter for fermentation. Inner pipes provide inoculation, fluid nutrient, and air for fermentation of microorganisms. The reaction fermenter is accompanied with a dry circulation unit and a production collection unit for drying and collection. The solid-state fermentation processes are thus effectively integrated without the need of transferring fermented products between stations, which largely reduces contamination rate. Even more, there is no need to purchase automatic production equipments of high mechanical technologies.
