  • Publication number: 20150219919
    Abstract: Polarizing beam splitter is disclosed. The polarizing beam splitter includes a first polymeric prism, a second polymeric prism, a reflective polarizer that is disposed between and adhered to a hypotenuse of each of the first and second polymeric prisms, and a hardcoat that is disposed on each of the first and second polymeric prisms. The polarizing beam splitter includes an input major surface and an output major surface. At least one of the input and output major surfaces has a pencil hardness of at least 3H. The polarizing beam splitter has a low birefringence such that when polarized light having a first polarization state enters the optical element from the input major surface and travels through at least 2 mm of the polarizing beam splitter and exits the polarizing beam splitter from the output major surface, at least 95% of light exiting the polarizing beam splitter is polarized has the first polarization state.

  • Publication number: 20030207094
    Abstract: An image recording sheet comprising a substrate having a first surface opposite a second surface. A toner receptor layer coated on at least the first surface of the substrate includes a binder having a concentration from about 19 dry wt % to about 80 dry wt % of the receptor layer. The binder holds a conductive polymer and a filler having a concentration from about 19 dry wt % to about 80 dry wt % of the receptor layer. The filler interacts with the conductive polymer to provide an antistat imparting to the toner receptor layer a surface resistivity in a range from 1011 ohms/square to 1013 ohms/square. The image recording sheet uses conducting polymers selected from polyanilines and polythiophenes in a concentration from about 0.5 dry wt % to about 3.0 dry wt % of the receptor layer. Suitable fillers have an average particle size from about 5 nm to about 100 nm.

  • Patent number: 6568814
    Abstract: A front image projection device and corresponding method are disclosed that utilize a shaped imager component to pre-distort an input image and thereby compensate for the distortion expected in a screen image. The front projection device includes projection components, image generating components, and illumination components. The shaped image component may compensate at least in part for distortion introduced due to the components of the projection system. The physical configuration for the shaped imager may be determined through a modeled or actual ray trace through the projection system, and the resulting physical configuration may be a geometric shape having a curved top, a curved bottom and curved sides.

  • Patent number: 6391954
    Abstract: The invention provides a recording sheet including an additive, referred to herein as a compatibilizer, to improve the quality of images formed by toner powder development of electrostatic charge patterns. Recording sheets, carrying images produced by toner powder transfer and fusion on a receptor surface, according to the present invention, exhibit improved light transmission and reduced light scattering. Specifically, a transparent sheet is provided having a toner-receptive coating containing about 4 wt. % to about 25 wt. % of a compatibilizer on at least one surface, wherein the coating has a low density yellow Q factor value at least 2 less than an identical coating without the compatibilizer.

  • Patent number: 6219519
    Abstract: Hot offset of black toner is reduced or eliminated in a color electrophotographic imaging device, such as a laser printer, by applying a minimal layer of non-black toner in addition to the black toner on a print media. The non-black toner, such as cyan, magenta or yellow toner, acts as a release agent for reducing or eliminating hot offset of the black toner during fusing of the toner to the media. The non-black toner is applied as a thin layer just sufficient to reduce hot offset of the black toner and such that an appearance of a resultant image formed retains a visual perception of being a black toner only image. In an alternate embodiment, the thin layer of non-black toner is applied in response to coated media being processed, such as overhead transparencies, that are more susceptible to hot offset.
