A projection system can include a projector, a screen, a spine, a base, a projector shroud, and a shelf. In some embodiments the spine is made of steel piping. In some embodiments, the spine is hollow and can accommodate a first cable. In some embodiments the screen is an ALR screen. In some embodiments, the system utilizes an ultra-short throw projector lens. In some embodiments, the base is a steel plate. In some embodiments, the projector system includes a counterbalance. In some embodiments, the projector shroud and/or shelf is/are configured to increase ventilation and/or act as heat sink(s). In some embodiments, the projection system includes a remote-control extender.

A whiteboard film (100) according to an embodiment of the present invention includes: a diffuse reflection layer (40) to diffuse-reflect visible light; an absorptive polarizing layer (20) having a first transmission axis that is parallel to a first direction; and a reflective polarizing layer (10) being disposed between the diffuse reflection layer (40) and the absorptive polarizing layer (20) and having a second transmission axis that is substantially parallel to the first direction. A whiteboard (100a) according to an embodiment of the present invention includes: a diffuse reflection plate (40a) to diffuse-reflect visible light; an absorptive polarizing layer (20) having a first transmission axis that is parallel to a first direction; and a reflective polarizing layer (10) being disposed between the diffuse reflection plate (40a) and the absorptive polarizing layer (20) and having a second transmission axis that is substantially parallel to the first direction.

The writable screen of the present invention includes a base layer and a resin layer provided on the base layer. The resin layer has a surface gloss of 1% to 20% and a surface pencil hardness of 5H to 2B. The present invention can improve the erasability with a whiteboard eraser for writing made with a whiteboard marker and also can prevent or reduce the occurrence of a hot spot and glare.

A visual partition system is provided. The system comprises a number of dry mist dispensers that generate a particle curtain comprising liquid micro-droplets. A gutter system collects liquid from the particle curtain, and at least one vacuum extractor is operably coupled to the gutter system. A liquid recirculation system collects liquid from the gutter system via the at least one vacuum extractor and returns it to the dry mist dispensers for reuse of the liquid.

A method for manufacturing a projection screen and a projection screen are provided. The method includes: preparing a substrate; under a first preparation condition, forming a reflective layer by vacuum plating above the substrate; and under a second preparation condition, forming a diffusion layer by the vacuum plating on the reflective layer. The second preparation condition is different from the first preparation condition, and a sputtering power in the second preparation condition is higher than a sputtering power in the first preparation condition.
