  • Patent number: 11911536
    Abstract: The present invention relates to a method for molding a self-supporting silk fibroin catheter stent, which comprises preparing an excellent catheter stent by a mold casting and freeze-drying molding process using silk fibroin as a raw material. The raw material is silk fibroin extracted from natural mulberry silk; and the mold is a hollow tubular mold, having an outer shell that is a transparent polyethylene straw with a diameter of 6 mm and an inner core that is a fiber rod FRP with a diameter of 3 mm, with the two ends being closed. The mold casting and freeze-drying molding process comprises the steps of casting; pre-freezing; removing the mold and placing the mold onto a pre-frozen freeze-drying plate; and freeze-drying. The freeze-drying procedure comprises: (1) a pre-freezing stage; (2) a freezing-vacuum transition stage; (3) a gradient temperature-rising and freeze-drying stage; and (4) a secondary freeze-drying stage.

  • Publication number: 20220404711
    Abstract: A method for monitoring performance of a manufacturing process is described. The method includes receiving one or more input signals that convey information related to geometry of a substrate generated by the manufacturing process; and determining, with a prediction model, variation in the manufacturing process based on the one or more input signals. A method for predicting substrate geometry associated with a manufacturing process is also described. The method includes receiving input information including geometry information and manufacturing process information for a substrate; and predicting, using a machine learning prediction model, output substrate geometry based on the input information. The method may further include tuning the predicted output substrate geometry.

  • Publication number: 20170202775
    Abstract: A preparation method of lipid bubbles by utilizing the principle of natural adsorption and assembly of amphiphilic lipid molecules on a gas-liquid interface comprises the steps of mixing gas-dissolved water containing free bubbles with lipid materials, and then the lipid materials are dispersed in the free gas nanobubble aqueous solution, and, in the presence of free bubbles, adsorbed and assembled on the gas-liquid interfaces so as to form lipid bubbles. The method is different from the traditional ultrasound cavitation, the mechanical force action, the novel ink jet printing method, the microchannel method and other methods for preparing bubbles.

  • Patent number: 8125970
    Abstract: A ranging method is described for measuring distance between a central node and an equipment node in a beacon wireless personal area network. At the beginning stage, the central node calculates the parameters needed in the ranging operation and sends these parameters to the equipment nodes by beacon frames. Equipment nodes, in turn, send ranging frames at time slots assigned thereto according to the information received in the beacon frames. The central node calculates beacon frame flight time by recording the sending time and the arrival time of the ranging frame, and then calculates the distance between the central node and the equipment node. For nodes failing in the ranging procedure, the ranging parameters are changed according to failing reasons and the above procedure is repeated until a ranging result is received without failure.

  • Publication number: 20100223591
    Abstract: A method for converting a web service composition logic and an application server includes: obtaining a first BPEL process framework of an existing BPEL composition logic; generating a DAG composition logic according to the first BPEL process framework; obtaining an independent path group according to the DAG composition logic; analyzing an independent path grouping result to generate a second BPEL process framework; and filling a process of the second BPEL process framework to generate an executable process. An application server is provided to convert the web service composition logic. The method and the application server provided herein optimize the logic through parallelism or nesting of web service invocation, and improve the execution efficiency.
