    摘要: A printer luminescent ink sensor for a printing device including a radiant energy source; and a photodetector located downstream from a print head of the printing device. The photodetector is adapted to detect luminescent energy from an indicium printed by the print head, upon exposure to radiant energy from the radiant energy source, substantially immediately after the indicium is printed.

    摘要: A windowed envelope is disclosed comprising: a first panel with an interior and an exterior side; a second panel attached to the first panel to define an interior portion having opposite side edges, a closed edge portion and an opening portion opposite the closed edge portion to provide access to the interior portion of the envelope; and a flap for sealingly adhering to an exterior surface of the first panel. The flap has an interior and an exterior side and is attached to the second panel at an edge of the second panel opposite the closed edge portion. The envelope comprises thereon an adhesive layer on the interior side of the flap comprising an adhesive; wherein a non-transparent window is located on the first panel or the second panel. The window comprises a reducible dye and a microencapsulated reducing agent, which is adapted to irreversibly change to a transparent window upon heating the non-transparent window to a temperature above room temperature.

    摘要: A system and method for distinguishing a first light source from other light sources utilizes an image receiver that can selectively engage and disengage a filter. The filter can be configured to block bands of light corresponding to the light being emitted by either the first source or the other sources. By alternately engaging and disengaging the filter from the image receiver, the first light source may be distinguished from other light sources.

    摘要: An EL device is presented which consists of a simple three active layer construction. A layer of a dielectric material, a traditional EL phosphor layer, and a quantum dot layer are present between an electrode and a transparent electrode. The EL device is operated efficiently by an AC source. Quantum dots which emit in the visible spectrum are used. The EL device is fully color tunable by altering the composition and thickness of the layers.
