Abstract: The present application relates to a control method of an aerial vehicle. The aerial vehicle may comprise a propulsion structure for providing flight power and a spraying apparatus for spraying a material. The control method may comprise determining current target information of the aerial vehicle during a process of the aerial vehicle performing a spraying task, wherein the current target information indicates wind field strength of a downward pressure wind field generated by the propulsion structure; determining, based on the current target information, a desired relative flight altitude of the aerial vehicle corresponding to the current target information relative to the material being sprayed below the aerial vehicle; and controlling the aerial vehicle to fly toward the desired relative flight altitude.

Abstract: A method for manufacturing rigid-flexible circuit board includes the step of providing an adhesive sheet defining at least one first opening, a copper foil, and a flexible board. The flexible board comprises a mounting region and a folding region. A removable sheet is pressed on a pressed surface of the adhesive sheet corresponding to each first opening. The copper foil, the adhesive sheet with the removable sheet, and the flexible board are pressed together in that sequence. The removable sheet corresponds to the folding region, and is embedded in the adhesive sheet. The copper foil contacts with the pressed surface and the removable sheet. An interspace is formed between the removable sheet and the flexible board. An outer conductive layer is formed on the copper foil. A removing region of the outer conductive layer corresponding to the folding region and the removable sheet is removed.

Abstract: The invention relates to a poly silsesquioxane-acrylic nanocomposite auxiliary for leather process and its preparation method. By mixing octavinyl silsesquioxane, organic solvent, ammonium persulfate, distilled water and surfactant in one system, and adding acrylic acid dropwise into the mixing system, cooling to adjust pH to obtain poly silsesquioxane-acrylic nanocomposite auxiliary for leather process. The auxiliary obtained in this invention is easily to penetrate into gap of the collagen fibers, and forms nano and micro-scale combination with the leather collagen, which can further improve the multi-point combination of the acrylic polymer with the collagen. Thus, the filling property of the leather that treated by the auxiliary is improved without affect the yield of leather, and the chromium content in the waste water is significantly reduced.

Abstract: A system and method for tagging and integrating event data into operational data with the aid of a digital computer is provided. A plurality of categories of tags are maintained, each of the categories comprising a plurality of tags. A note comprising data about an event from a user is received. One or more of the tags are assigned to the note based on the user and the data. One or more of the tags is received from the user and the note is tagged with the received tags. Operational data comprising workflow data of an objective nature is defined. The note is integrated into the workflow data using the received tags, the assigned tags, and the categories of the received tags and the assigned tags. The workflow data with the integrated note is displayed on a display.
