Abstract: Disclosed are apparatuses and methods for holding a document sheet in place against a scanning surface of an image capture system. One such apparatus is a document cover comprising: a body that is oriented parallel to the scanning surface when the document cover is in the closed position; a compliant and elastic document backing that is partially attached to the body and configured to reflect light originating from the image capture system; and a backing constraint configured to secure a central region of the document backing to the body and further configured to constrain movement of the central region in a first direction that is normal to the scanning surface while allowing movement in the same direction of outer regions that are lateral to the central region. The document backing generates a downward spring force which biases the outer regions toward the platen.

Abstract: A scanning device includes a scanning mechanism, a memory, a processing mechanism, and a scan rate adjustment mechanism. The scanning mechanism scans a media sheet having an image thereon at a variable scan rate, to yield raw data. The memory temporarily stores the raw data. The processing mechanism converts the raw data within the memory into processed data. The raw data is removed from the memory as the raw data is converted. The scan rate adjustment mechanism adjusts the variable scan rate, based on one or more of an amount of free space within the memory, a fill rate at which the raw data is filling the memory, and a removal rate at which the raw data is being removed from the memory, so that the memory does not become completely full.

Abstract: Methods of forming optoelectronic devices include forming an electrically conductive layer on a first surface of a substrate and forming a mirror backing layer from the electrically conductive layer by forming an endless groove that extends through the electrically conductive layer. A step is then performed to remove a portion of the substrate at a second surface thereof, which extends opposite the first surface. This step exposes a front surface of the mirror backing layer. An optically reflective mirror surface is then formed on the front surface of the mirror backing layer.

Abstract: A circuit connected to a linear array of photosensors generates image data representative of information printed on a document and adjusts the gains applied to the outputs of selected ones of the photosensors to eliminate streaks in the image data otherwise due to the selected photosensors imaging debris on an optical reference surface. The circuit determines which photosensors have low output values during a factory scan of a clean white reference surface. During a subsequent user environment calibration scan, low output values are adjusted to the average of their neighbors, but only for locations not identified as having low outputs during the factory scan. The circuit additionally performs a PRNU compensation and further adjusts the gains applied to each of the outputs of the photosensors so that all of their output values have a substantially uniform value.

Abstract: Add-drop optical switches include fixed reflectors, such as fixed mirrors, and movable reflectors, such as movable mirrors, wherein none of the fixed reflectors and none of the movable reflectors are oriented orthogonal to one another on a substrate when the movable reflectors that provide the add-drop functionality are in a radiation reflecting position. In preferred embodiments, each of the fixed and movable reflectors is oriented parallel to or at a 70° angle to, the remaining fixed and movable reflectors when the movable reflectors are in the radiation reflecting position. Most preferably, the fixed reflectors and the movable reflectors all are oriented on the substrate in parallel when the movable reflectors are in the radiation reflecting position. By providing these orientations of fixed and movable reflectors, add-drop optical switches may be fabricated on silicon substrates using wet etching along crystallographic planes. High performance add-drop optical switches thereby may be provided.

Abstract: A microelectromechanical structure capable of switching optical signals from an input fiber to one of two or more output fibers. In one embodiment, the MEMS optical cross-connect switch comprises a first microelectronic substrate having a pop-up mirror disposed on the surface of the substrate and a rotational magnetic field source, such as a variably controlled magnetic field source. The rotational magnetic field source allows for reliable actuation of the pop-up mirror from a non-reflective state to a reflective state. Additionally the invention is embodied in a MEMS optical cross-connect switch having a first microelectronic substrate having a pop-up mirror disposed on the surface of the substrate and a positioning structure disposed in a fixed positional relationship relative to the first substrate. The positioning structure may comprise a positioning structure extending from a second microelectronic substrate that is in a fixed positional relationship relative to the first microelectronic substrate. The positioning structure serves to restrict further movement of the pop-up mirror when the pop-up mirror has been actuated into a reflective state.
