Abstract: A surgical instrument (10) includes a housing (20) defining a longitudinal axis and a first assembly (200) and a second assembly (300) operably coupled to the housing (20). The first assembly (200) includes a first function button (200b) pivotably coupled to the housing (20) about a first pivot (200p) and a first circuit (210) supported by the housing (20) and aligned with the first pivot (200p). The first function button (200b) includes a first arm (201) on a first side of the first pivot (200p) and a second arm (202) on a second side of the first pivot (200p). The first circuit (210) is aligned with the cutting picot between the first arm (201) and the second arm (202) and includes a first actuator (211) on the first side of the first pivot (200p) and a second actuator (212) on the second side of the first pivot (200p).

Abstract: The present disclosure relates to a target object tracking method and apparatus, an electronic device, and a storage medium. The method includes: obtaining a first reference image of a target object; determining time information and location information of the target object in an image to be analyzed according to the first reference image, the image to be analyzed including the time information and the location information; determining a trajectory of the target object according to the time information and the location information of the target object; and generating tracking information for tracking the target object according to the trajectory of the target object. Embodiments of the present disclosure obtain highly-accurate tracking information of the target object according to the trajectory of the target object determined in the image to be analyzed by using the first reference image of the target object, such that the success rate of target object tracking is improved.

Abstract: Disclosed is a pretreatment method for improving antioxidation of steel T91/P91 in high temperature water vapor, which includes applying a slurry, containing rare earth oxide, on a surface of a substrate; holding the temperature in a gas mixture environment of inert gas and water vapor after drying; and cleaning away the solid powder left by the slurry on the surface, thereby obtaining the substrate with a surface rich in chromium and having a small amount of rare earth oxide. As a result of the method, the antioxidation capability of steel T91/P91 in the 500-750° C. water vapor environment can be improved, and films rich in chromium oxide can be formed on the surface of steel T91/P91.
