    摘要: A system and a method print one or more images to one or more reimageable documents, wherein the one or more representative of at least a portion of a digital file. The method includes a connecting a portable printer to a computing device. Moreover, the method includes emitting ultraviolet light from a light source, wherein an imaging layer of the reimageable document is imagable by ultraviolet light, wherein ultraviolet light forms a color contrast on the imaging layer that defines an image representative of at least a portion of the digital file.

    摘要: An image forming method composed of: (a) providing a reimageable medium composed of a substrate and a photochromic material, wherein the medium is capable of exhibiting a color contrast and an absence of the color contrast; (b) exposing the medium to an imaging light corresponding to a predetermined image to result in an exposed region and a non-exposed region, wherein the color contrast is present between the exposed region and the non-exposed region to allow a temporary image corresponding to the predetermined image to be visible for a visible time; (c) subjecting the temporary image to an indoor ambient condition for an image erasing time to change the color contrast to the absence of the color contrast to erase the temporary image without using an image erasure device; and (d) optionally repeating procedures (b) and (c) a number of times to result in the medium undergoing a number of additional cycles of temporary image formation and temporary image erasure.

    摘要: A cholesteric display including a liquid crystalline mixture having a dipolar dopant dissolved in the liquid crystalline mixture and the resulting mixture is reflecting light in the visible range of the spectrum when in planar state. In accordance with another aspect, a process includes forming a composition with a dipolar molecule to result in a liquid crystal dipolar dopant, and liquid crystal is added to the composition. In accordance with still another aspect, a device includes a liquid crystal composition includes a cholesteric liquid and a dipolar dopant. The liquid crystal composition is switchable between a focal-conic state and a planar state in the presence of an electric field and is stable in the respective state when the electric field is removed.
