This application discloses a spatial light modulator, driving method, free-space optical antenna, device, and system, relating to the field of free-space optical communication technology. The spatial light modulator includes a first substrate, a first electrode, a liquid crystal layer, a second electrode, and a second substrate. The first electrode is a planar electrode, and the second electrode includes multiple sub-electrodes spaced apart from each other. The multiple sub-electrodes are arranged sequentially from the inside to the outside around a center. When different driving voltages are applied to the first electrode and the sub-electrodes respectively, the liquid crystal material in the liquid crystal layer flips under the action of the electric field, resulting in different equivalent dielectric constants of the liquid crystal material. This allows the spatial light modulator to adjust the intensity and phase of the incident light beam to modulate different types of light beams, achieving adaptive switching of light beam types. In particular, it can achieve adaptive switching of different types of light beams in a sharp beam, improving anti-turbulence capability and enhancing the stability of the communication link.

The utility model discloses a simple line drawing device for highway engineering construction, which comprises a first frame and a front roller connected to the bottom of the first frame, the top of the first frame is connected with a first extension rod, and the top of the first extension rod is connected with a grip; a second extension rod is hinged to a rod body of the first extension rod, the other end of the second extension rod is connected with a second frame, the bottom of the second frame is connected with an auxiliary roller, and a limiting plate is arranged above the hinged position of the second extension rod and the first extension rod; a hopper is connected to a rod body of the first extension rod, a valve is connected to the bottom of the hopper, a material guiding guide pipe is connected to the valve and connected to the second extension rod and an L-shaped rod through fastening assemblies, one end of the L-shaped rod is connected to the second frame, and the other end of the L-shaped rod is arranged behind the auxiliary roller. According to the lime scattering device, the workload can be reduced, the working efficiency is improved, the lime scattering uniformity is improved, the lime scattering opening is close to the ground, and lime scattering is not prone to being caused.

This utility model discloses a smoke exhaust pipe, a smoke exhaust assembly, and an integrated stove, belonging to the field of integrated stoves. It includes a pipe body with cross-sectional shapes on a plane perpendicular to its smoke exhaust direction. Each cross-sectional shape is parallel to a common direction, and the projected length of each cross-sectional shape along the common direction is less than or equal to the projected length of its corresponding plane in other directions. The smoke inlet of the pipe body is a first smoke inlet, and a connecting structure for connecting to the exhaust hood is also provided at the first smoke inlet of the pipe body. The technical advantage of this utility model is that the smoke exhaust pipe only occupies a small portion of the width used to conceal the cabinet, allowing for a larger remaining usable width in the cabinet, indirectly increasing the usable storage space of the cabinet.

This utility model discloses a front-body down-filling quilting mold, comprising: a base plate and a cover plate. The base plate is provided with a base plate front-body down-filling quilting groove and a base plate pocket quilting groove. Next to the base plate front-body down-filling quilting groove are provided a base plate PVC-coated horsehair interfacing, a base plate front-body piece outline reference line, and a base plate pocket piece outline reference line. The cover plate is provided with a cover plate front-body down-filling quilting groove and a cover plate pocket quilting groove. Next to the cover plate front-body down-filling quilting groove is a cover plate PVC-coated horsehair interfacing. With reference lines for the outline of the front panel and the pocket position of the cover plate, this utility model allows for the simultaneous placement of the outer and lining fabrics of the front panel garment on the base plate, followed by the placement of the cover plate. This completes the quilting and positioning of the pocket opening, enabling the next step in the process. This significantly improves production efficiency, simplifies the production process, saves production costs, and avoids accidental crooked sewing due to the thinness of the fabric, resulting in waste pieces. The quilting is fast, efficient, aesthetically pleasing, and consistent in width.
