  • Patent number: 11788972
    Abstract: A method of automatically setting optical parameters, using Automatic Optical Inspection (AOI) System, the method includes the following steps. Firstly, a recommended object image is obtained when the AOI system is set under a first recommended optical parameter set. Then, a computation is performed on an object standard picture and a recommended object image to obtain a recommended error value between the object standard picture and the recommended object image according to an optimized error function. Then, whether the recommended error value converges is determined. Then, when the recommended error value does not converge, a computation is performed to obtain a second recommended optical parameter set according to the recommended error value and the first recommended optical parameter set. Then when the recommended error value converges, the first recommended optical parameter set is decided as an optimal optical parameter set of the AOI system.

  • Patent number: 10635741
    Abstract: A method and a system for analyzing a plurality of process factors affecting the trend of a continuous process are provided. The method includes the following steps: A plurality of similar time periods are selected from a time series. The trend of the continuous process in each of the similar time periods is similar to the trend of the continuous process in a current time period. A contribution of each of the process factors corresponding a monitoring target is analyzed according to the process factor values in the similar time periods and a plurality of monitor target values of the monitoring target. Part of the process factors are picked out according to the contributions.

  • Publication number: 20160347835
    Abstract: A tGal-3BP-Fc fusion protein, a pharmaceutical composition, an isolated nucleic acid, a recombinant expression vector, and a method of inhibiting, decreasing, reducing, suppressing or limiting metastasis of cancer cells, and immunosuppressing or modulating phagocytosis and T-cell functions by using the same are disclosed herein. The tGal-3BP-Fc fusion protein comprises: a truncated Gal-3 binding protein with domain 4, and at least an Fc fragment of an immunoglobulin G. A pharmaceutical composition comprises the tGal-3BP-Fc or Fc-tGal-3BP fusion protein, and a pharmaceutically acceptable carrier. The method comprises a step of administrating the pharmaceutical composition to a subject in a therapeutically effective amount to inhibit, decrease, reduce, suppress or limit invasiveness and metastasis of cancer cells or to treat or modulate immune reactions of inflammatory diseases in the subject.
