  • Publication number: 20250101373
    Abstract: Disclosed in the present invention is a cell culture method, including the following steps: first loading a one-step container body (1) into a microenvironment; adding a cell culture solution to the one-step container body (1); and successively adding a supplementary fluid to the one-step container body (1) as the culture time increases. The one-step container body (1) has at least two inner side surfaces with different areas. The inner side surfaces with the different areas form corresponding culture surfaces (2) for culturing cell solutions with different volumes. The cell solutions are first borne on a small-area culture surface (2) to be cultured. As the volumes of the cell solutions increase, the cell solution is borne on the large-area culture surface (2) to be cultured. Further disclosed is a cell culture container, including a one-step container body (1).

  • Patent number: 11215811
    Abstract: Disclosed is a drying-wetting separated filling method and a filling apparatus for an electrowetting display device. The filling method comprises filling a non-polar solution into pixel grids on a lower substrate of an electrowetting display device in air, and filling a polar solution to immediately cover the non-polar solution filled after filling the non-polar solution into the pixel grids. Compared with filling the non-polar solution into the polar solution, directly filling the non-polar solution in air has better filling uniformity, easier operation and control. With the method, the fillings of the polar solution and the non-polar solution are easy, having a higher filling efficiency, and no air bubble residue.

  • Patent number: 9619512
    Abstract: Described is a memory searching system, including an indexing module and a searching module. The indexing module, provided with multiple indexed databases, acquires and records updated indexed data in an indexed database provided to the indexing module and synchronizes the searching module with the updated indexed data recorded in the indexed database provided to the indexing module. The searching module updates an indexed database in a memory with the updated indexed data received from the indexing module (the indexed database in the memory corresponds to the indexed database provided to the indexing module), and switches a pointer of the indexed database to the updated indexed database in the memory. Also described is a memory searching method, a real-time searching system and method, capable of better supporting real-time search and of updating indexed data in seconds in a realistic application, reducing the cost of hardware equipment and improving searching efficiency.
