Abstract: A system, comprising: a first array of lasers; a first linear polarizer; a second array of lasers; a second linear polarizer provided at an angle with respect to the first linear polarizer; a first beamsplitter coupled to the first linear polarizer; a phosphor assembly; a collimator lens; a third linear polarizer; a second beamsplitter coupled to the third linear polarizer; and a telephoto lens.

Abstract: A system may comprise a projection surface and a light source. The projection surface may comprise a first layer comprising a material that prevents reflection of light, a second layer comprising a transparent image forming material, and a third layer comprising a privacy screen filter. The second layer may be provided between the first layer and the third layer. The light source may be configured to emit light on the projection surface to create an image on the projection surface. The light source may face the first layer. The light may be emitted at a projection angle on the projection surface. The third layer may cause the projection surface to appear translucent from a viewpoint of the light source emitting the light at the projection angle.

Abstract: A device for lining the inner surface of a cargo container includes a fluid impervious flexible bag which lines the entire inner surface of the wall of the cargo container, and magnetic elements to hold the flexible bag against the inner surface of the wall of the cargo container, the magnetic elements being distributed on the inner surface of the wall of the cargo container at appropriate intervals.
