Abstract: The present application provides a solder paste dispensing feedback system (10) for a circuit board printer. The system (10) comprises a solder paste container (101), a solder paste extruding device, a first sensor, a second sensor and a control device. The solder paste container (101) is used to contain solder paste and has an outlet. The solder paste extruding device is used to extrude the solder paste from the outlet of the solder paste container (101). The first sensor is used to detect solder paste in the solder paste container (101), and generate a first signal to indicate whether the solder paste container (101) still contains solder paste. The second sensor is used to detect an operating state of the solder paste container (101), and generate a second signal to indicate whether solder paste is extruded from the outlet of the solder paste container (101).

Abstract: The present application discloses a fitting apparatus (100) for fitting a sealing member (110) onto a solder paste nozzle (230), the sealing member having a sealing member mounting hole (112), and the fitting apparatus comprising: a support plate (116); at least two first power sources (101, 102, 103, 104); at least two insertion members (121) and a second power source (105). By controlling the driving directions and driving sequence of multiple power sources, the fitting apparatus of the present application completes the work of expanding the sealing member mounting hole in a mechanical fashion; an operator then only needs to pass the base plate of the nozzle through the sealing member mounting hole in order to complete the fitting of the sealing member to the nozzle, so the operation is convenient and saves manpower.

Abstract: A method and system for publishing patent data, and a patent trading platform. The method includes the following steps: providing at least one description item information of a patent to be traded: obtaining and checking all description item information and legal status information of said patent according to the at least one description item information; obtaining a transaction price of said patent; and publishing the transaction price, all the description item information and the legal status information. According to the method for publishing patent data, all description item information and legal status information can be automatically obtained and checked after at least one description item information is input, so as to avoid the problem of wrong entry of patent information.

Abstract: A method for generating a zebra crossing includes: obtaining an original vertex sequence for generating a zebra crossing from an image, and determining a first vertex sequence by merging a plurality of vertices in the original vertex sequence; obtaining a plurality of lines by connecting a plurality of vertices in the first vertex sequence in order, and determining a first target edge and a second target edge approximate to the first target edge from the plurality of lines; obtaining a first vertex set corresponding to the first target edge and a second vertex set corresponding to the second target edge, and generating an area to be cut based on the first vertex set and the second vertex set; and cutting the area to be cut to obtain cutting elements, and generating the zebra crossing by filling alternately a part of cutting elements.

Abstract: The present invention discloses a system for preventing network content of one or more network servers from being tampered with. The system comprises a content caching and providing device to cache network content of the one or more network servers; and a content monitoring sub-system with one or more content monitoring client incorporated in the network servers respectively and a content monitoring server part incorporated in the content caching and providing device.
