Abstract: A quick disassembly and assembly structure of a shower head includes a shower head main body, a side of the shower head main body away from a water outlet cover being provided with a mounting portion; and a fixed base provided with a connecting portion correspondingly. One of the mounting portion and the connecting portion is provided with a movable member, the other of the mounting portion and the connecting portion is provided with a control unit. The control unit comprises a limiting member and a guide member; when the shower head main body moves to a first position, the shower head main body is fixedly mounted on the fixed base; when the shower head main body moves to a second position; which is convenient to operate, labor-saving, simple in structure, and stable in function.

Abstract: A handheld gimbal may include a body and a control assembly. The body may include one or more axis assemblies. Each of the one or more axis assemblies may include an arm and a motor for driving the arm to move around an axis. The control assembly may be configured to detect a change of a configuration of the handheld gimbal. The control assembly may also be configured to control at least one of the motors of the one or more axis assemblies to move the respective arm under a joint angle control mode.

Abstract: A reagent filling device and a sample analyzer with the reagent filling device. The reagent filling device includes a base, a horizontal rotation component, a vertical lifting component and a cantilever component, wherein, the horizontal rotation component is connected with the base, the vertical lifting component moves in a vertical direction relative to the base, the vertical lifting component drives the cantilever component to move along the vertical direction, the cantilever component is rotatably arranged relative to the vertical lifting component, there are a plurality of cantilever components, the cantilever component includes a cantilever body, a length of the cantilever body of at least one cantilever component is greater than a length of the cantilever body of each of the rest cantilever components, and the cantilever component is configured to add a reagent in a reagent disc to a reaction cup in a reaction disc.

Abstract: An image capture method includes obtaining one or more control parameters and a shooting range, obtaining an image amount according to the one or more control parameters and the shooting range, determining shooting angles according to the shooting range and the image amount, and performing image capture according to the shooting angles.

Abstract: A motion trajectory determination method includes obtaining at least one trajectory point of a gimbal that includes attitude information, obtaining, in response to receiving a trajectory point adjustment command, an actual attitude of the gimbal and adjusting the attitude information of a trajectory point to be adjusted according to the actual attitude, and determining a motion trajectory of the gimbal according to all of trajectory points of the gimbal.
