Abstract: Various embodiments relating to a modular marking apparatus and method are disclosed.

Abstract: Various apparatus and methods relating to the use of alignment assist images and non-alignment assist images for capturing images of one or more targets are disclosed.

Abstract: Image data processing methods, image data processing systems, and articles of manufacture are described. According to one aspect, an image data processing method includes accessing initial image data of a first image representation of a scene, selecting one of a plurality of imaging conditions, wherein the selected one of the imaging conditions is different than an initial one of the imaging conditions used to generate the initial image data, and processing the initial image data using the selected one of the imaging conditions to provide processed image data of a second image representation of the scene different from the first image representation of the scene, wherein the second image representation of the scene represents the scene as if it were captured according to the selected one of the imaging conditions.

Abstract: The placement of a physical object at a location on a surface is detected. A virtual shadow for the physical object is displayed at the location on the surface.

Abstract: A color image is displayed on a screen and a luminance image is projected onto the screen. The luminance image has a greater resolution than the color image.

Abstract: A method and apparatus apply an electric field across active layer, wherein active layer is configured to change from a first light attenuating state to a second lesser light attenuating state in response to the applied the electric field and wherein the second lesser light attenuating state permits light to be reflected from a light reflective face.

Abstract: Embodiments of an optical device including at least two transparent layers are disclosed.

Abstract: A reflective display screen comprises a first component surface responsive to absorb low level ambient light from above the screen and a second surrounding component surface responsive to light of high intensity from an image source. The first component surface is graphically formed to represent a fixed permanent image within the screen viewable only in ambient overhead lighting and without incidence of the high intensity light from the image source. Other embodiments include a method of displaying a permanent, fixed image and a method of making a display screen.

Abstract: In embodiments, an intensity of light is adjusted according to data indicating the states for elements.

Abstract: A computing system responds to an event that wakes the computing system from a sleep mode. The computing system recognizes the event and responds to the event. The response includes generating an event notification message that is transmitted to an external device separate from the computing system. The transmission is performed via wireless communication. The computing system then returns to the sleep mode.

Abstract: Embodiments of synchronizing modification of an optical characteristic of a screen are disclosed.

Abstract: Embodiments of adjusting light intensity are disclosed.

Abstract: Embodiments of an optical device including at least two transparent layers are disclosed.

Abstract: Various apparatus and methods relating to the use of alignment assist images and non-alignment assist images for capturing images of one or more targets are disclosed.

Abstract: Embodiments of reflecting non-visible light off one or more mirrors are disclosed. In an embodiment, non-visible light may be reflected off of one or more mirrors in an off positon and a portion of a screen may be illuminated with the non-visible light. Other embodiments are also disclosed.

Abstract: Embodiments of an optical device including at least two transparent layers are disclosed.

Abstract: Various embodiments relating to initiating preconditioning of a printhead with a trigger prior to receipt of a print command are disclosed.

Abstract: An optically addressable display of a preferred embodiment uses emissions having plural polarizations to define a corresponding number of color channels. A data encoder applies data for each of the color channels to corresponding ones of the plural polarizations. The display also includes plurality of pixels for producing a color display. There is a plurality of receptors including at least one receptor for each pixel. The receptors activate pixels depending upon which, if any, of the plural polarizations is received.

Abstract: Embodiments of modifying an optical characteristic of a screen are disclosed.

Abstract: A projection system includes a cabinet having a surface with an aperture therein, a projector disposed within the cabinet, adapted to project light through the aperture in the surface of the cabinet, and a lens disposed in the aperture to project the light onto a screen disposed generally non-parallel to the cabinet surface having the aperture.
