    摘要： A circuit for guiding electromagnetic waves includes a substrate for supporting components of the circuit. The circuit includes a control device which includes a first conductive element on the substrate for connection to a first component of the circuit and a second conductive element on the substrate for connection to a second component. The control device is made up of a variable impedance switching material on the substrate which exhibits a bi-stable phase behavior. The compound has a variable impedance between a first impedance state value and a second impedance state value which can be varied by application of energy thereto to thereby affect the amplitude or phase delay of electromagnetic waves through the circuit.

    摘要： Disclosed is liquid crystal paper and an erasing device that is not permanently connected to the liquid crystal paper. A sheet of liquid crystal paper includes flexible polymeric substrates. A polymer network or a spacer network, in which bistable cholesteric reflective liquid crystal material is dispersed, is disposed between two of the substrates. Optional alignment layers or optional electrically conductive layers sandwich the liquid crystal material therebetween. An optional layer of light absorbing material is disposed near one of the substrates. Application of pressure to an upper substrate changes a focal conic nonreflective texture of the liquid crystal material to a reflective planar texture. The erasing device applies a voltage or heat for erasing the paper by changing the reflective planar texture to the focal conic nonreflective texture.

    摘要： The present invention relates to a display film that may be transferred by lamination or otherwise onto a substrate. The display film is formed of a stack of layers that can include different types, arrangements, and functionality within the stack depending upon factors including the characteristics of the substrate (e.g., upper or lower, transparent or opaque, substrates) and addressing of the display (e.g., active or passive matrix, electrical or optical addressing). The layers of the stacked display film include one or more electrode layers and one or more liquid crystal layers and, in addition, may include various combinations of an adhesive layer, preparation layer, casting layer, light absorbing layer, insulation layers, and protective layers. The liquid crystal layer can include cholesteric or other liquid crystal material. The liquid crystal layer can be a dispersion of liquid crystal in a polymer matrix formed by a variety of techniques. The display film may interact with components mounted on or laminated to the substrate, including a solar cell, active matrix backplane and electrodes. The display film may be mounted onto flexible or drapable substrates such as fabric and can itself be drapable. Thus, the invention offers substantial flexibility in fabrication and design that has not been previously possible in the display industry.

    摘要： A conical deflector receives light from a source through an opening at the narrow end of the cone. In one embodiment, an optical fiber bundle supplies light directly into the cone. In another embodiment, the conical deflector receives light via an optical integrating cavity. A substantial portion of the inner surface of the cones has a specular reflectivity. The entire surface may be uniformly specular (e.g., highly specular). Alternatively, one or more sections of the inner walls of the cone may have a diffuse reflectivity or a different degree of specular reflectivity (e.g., quasi-specular). The deflector is dimensioned relative to a narrow, desired field of view and the light source to deflect light that would otherwise pass out of the desired field of view, so as to efficiently illuminate the desired field of view. The conical deflector provides a substantially uniform light intensity distribution over the desired field of view.
