The present invention provides a marquee animation display method for a string light control program, as well as a corresponding terminal. The method comprises the following steps: S1: Shape generator generates multiple light bead graphics, which together form a string light graphic; S2: Animation generator generates keyframe animations; S3: Light bead graphics are bound to the keyframe animations, and the string light graphic is added to the display view to present marquee animation effect. This marquee animation display method enhances the efficiency and smoothness of marquee animation rendering, reduces the performance consumption of the terminal device running the string light control program, and improves the user experience.

The invention discloses Christmas Tree Transportation Device and Its Method of Use, addressing the challenge of bulky trees that require multiple people to carry and are cumbersome to operate. It comprises an upper body, lower body, and construction structure. The upper and lower bodies are equipped with adhesive structures, allowing them to unfold and adhere to form the tree's halves. These halves are connected into the whole Christmas tree through a construction structure. The upper body includes long cardboard and leaf-shaped paper sheets, which are reusable due to their concentric-circle, vertically stacked design. Made of paper, the tree can be repeatedly disassembled and reassembled without damaging its structure or appearance, making it sustainable. Its compact structure allows for easy folding, packing, carrying, and transporting.

The invention concerns a laser plant supplementary lighting device (14) comprises a base (120), a light homogenizing member (101), a control device (106), a light source, a driving circuit, a communication device (7), and a sensing component; the control device is configured to generate a first reference light intensity information based on an environmental parameter information, and generate a second reference light intensity information based on a plant-related information and the environmental parameter information, and generate operating parameters of the light source based on the first reference light intensity information and the second reference light intensity information, and control the driving circuit to adjust relevant parameters of the light source based on the operating parameters. The device can comprehensively consider different growth stages of plants and environmental factors in the current environment to adjust the output of the light source in the laser plant supplementary lighting device (14), reduce the energy consumption of the entire laser plant regulation apparatus.

The laser supplementary lighting system for plant factories includes a laser emitter (1), a control circuit (2), a lens array (3), and first and a second reflector arrays (4,5); collimating lenses (13,17) are arranged in the laser emitter (1); the collimating lenses (13,17) collimate laser beams into collimated beams with a divergence angle of less than 0.3°; a bottom surface of the laser emitter (1) and emission ports on both sides in a horizontal direction are configured to emit long-wave laser beams and short-wave laser beams; three laser beams emitted from the laser emitter (1) are reflected by the first reflector array (4), reflected by the second reflector array (5), and homogenized by the lens array (3), respectively, and then projected downward to form rectangular light spots. The disclosure has the advantages of low energy consumption and low cost and realizes a high-uniformity multi-wavelength laser field with a large area at a short distance.

The present disclosure discloses a monoleaflet mechanical valve, which includes a mechanical valvular annulus, a limiting base, a movable valve leaflet and a guide rod; the mechanical valvular annulus is provided with a through-via in the middle; the limiting base is mounted on the bottom of the mechanical valvular annulus, and an open movement area is defined between the mechanical valvular annulus and the limiting base; both the movable valve leaflet and the guide rod are located in the movement area, the movable valve leaflet can reciprocate up and down along the trajectoy direction of the guide rod, such that the movable valve leaflet can movably open or close an entire passage opening of the through-via, so as to realize the relative increasing of the orifice area and a small transvalvular pressure gradient. According to the present disclosure, by means of the cooperation between the movable valve leaflet and the guide rod, thrombosis is effectively prevented, and the monoleaflet mechanical valve cannot be easily damaged. Even if thrombi are formed, the monoleaflet mechanical valve cannot easily get stuck, avoiding the risk of valve sticking or dysfunction, and the anticoagulant therapy can be reduced or is not needed. The mechanical valve provides a larger orifice area, significantly improving the performance of the valve, and therefore, the mechanical valve is suitable for more clinical patients, particularly patients with a small valvular annulus or underweight.
