Abstract: A computer-controlled system for producing a multi-color image on a substrate using multi-colored cholesteric liquid crystal (CLC) pigment materials made from CLC flakes tuned to predetermined bands of color. An image generator automatically generates an image specifying a pattern over which binder material is to be applied to a substrate by a binder material applicator. A plurality of CLC pigment applicators automatically apply patterns of different-color CLC pigment material to the pattern of binder material, which binds thereto as the binder material dries according to its drying characteristics. An output device is used to automatically return the substrate to a different one of CLC pigment applicators after each application of a pattern of different-color CLC pigment material to the pattern of binder material. The output device automatically repeats the return of the substrate to the CLC pigment applicators until all bands of color in the multi-color image are rendered.

Abstract: A method of printing using dry pigments is introduced, wherein a binder material is applied to the surface of an object uniformly or in a pattern, and then dry pigment is applied to the binder material in a pattern or uniformly. The dry pigment sticks to the patterned binder, or the patterned pigment may be bound to the uniform binder, to produce a pattern.

Abstract: A light controlling film is described comprising a polymerized polymer network of a crosslinked high molecular weight polymeric material and a low molecular weight cholesteric liquid crystal (CLC) material, wherein the high molecular weight and the low molecular weight form a material having cholesteric liquid crystal (CLC) order such that the film is a reflective circular polarizer whose bandwidth is controllable by an electric field impressed in the film.

Abstract: A light controlling film is disclosed, comprising a polymerized polymer network varying spatially in a direction normal to the film surface, where the polymerized polymer network is a crosslinked high molecular weight polymeric material mixed with a low molecular weight nematic material exibiting cholesteric liquid crystal (CLC) order, wherein wherein an electric field impressed in the film controls the reflection of circularly polarized light.

Abstract: A multi-mode stereoscopic imaging system is described. It is the first stereo system which is convertible back and forth from the auto stereo viewing mode without glasses to the binocular stereo viewing mode with glasses. It is based on micro-polarizer arrays and spatial multiplexing of images. The system consists of a stereo image component and an auto parallax barrier component. Both components use the properties of &mgr;Pols. Switching from one mode to the other is accomplished manually, and electronically with the aid of a liquid crystal light valve. The system combines the benefits of auto-stereo imaging and the binocular stereo imaging of prior art techniques without their limitations.

Abstract: An "intelligent" window combined with an additional structure for further controlling light incident on the "intelligent" window is disclosed.
