Abstract: A microfluidic device includes a processing layer and a temperature control layer. The processing layer applies a predetermined process to a subject fluid. The temperature control layer is disposed adjacent to the processing layer to give a predetermined temperature environment to the processing layer.
Abstract: A summary of a captured document image is produced on the basis of detected handwritten annotations made to a document prior to image capture. The scanned (or otherwise captured) image is processed to detect annotations made to the document prior to scanning. The detected annotations can be used to identify features, or text, for use to summarize that document. Additionally, or alternatively, the detected annotations in one document can be used to identify features, or text, for use to summarize a different document. The summary may be displayed in expandable detail levels.

Abstract: A system for reducing lead edge (LE) smearing in an electrostatographic machine is provided. The system comprises a pretransfer corotron positioned between a developing station and a transfer station in an electrostatographic imaging device. The pretransfer corotron is configured to apply a predetermined charge to at least a portion of a developed toner image on a photoreceptive surface. The predetermined charge is greater than a charge applied to the rest of the developed toner image. The system further includes a controller operably associated with the pretransfer corotron. The controller is configured to activate the pretransfer corotron to apply said predetermined charge to the developed toner image at a lead edge region of the developed toner image when leading edge smearing is detected during imaging operations.

Abstract: Cells can include variable volumes defined between a flexible structure, such as a polymer layer, and a support surface, with the flexible structure and support surface being attached in a first region that surrounds a second region in which they are unattached. Various adhesion structures can attach the flexible structure and the support surface. When unstretched, the flexible structure can lie in a flat position on the support surface. In response to a stretching force away from the support surface, the flexible structure can move out of the flat position, providing the variable volume. Electrodes, such as on the flexible structure, on the support surface, and over the flexible structure, can have charge levels that couple with each other and with the variable volume. A support structure can include a device layer with signal circuitry that provides a signal path between an electrode and external circuitry. One or more ducts can provide fluid communication with each cell's variable volume.

Abstract: The invention provides a belt including a belt base having elasticity and a projection member having elasticity which is provided along at least one edge of the belt base so as to project from the belt base, and an adhesive layer which bonds the belt base and the projection member, wherein the ten-point average roughness Rz in the region of the belt base to be bonded with the projection member is about 4 ?m or more and the ten-point average roughness Rz in the region of the projection member to be bonded with the belt base is about 6 ?m or more.
Abstract: A storage medium is readable by a computer. The storage medium stores a program of instructions executable by the computer to perform a function for managing a job log. The function includes: creating a job log after execution of a job; generating a log image from an image handled by the job; and storing the log image in association with the job log.
Abstract: An image transmitting apparatus includes: an address acquiring component that acquires an first address of a document image on the basis of address information other than numbers added to the document image; an address input component that receives input of the second address with respect to the document image; a match determining component that determines whether or not the second address that the address input component has received and the first address that the address acquiring component has acquired match; and a transmitting component that transmits the document image in accordance with the determination result of the match determining component.
Abstract: A camera array captures plural component images which are combined into a single scene. In one embodiment, each camera of the array is a fixed digital camera. The images from each camera are warped to a common coordinate system and the disparity between overlapping images is reduced using disparity estimation techniques.
Abstract: Method and system embodiments herein add at least one trap area between abutting objects on an image to be printed by a printing engine. This trap area includes a central region between two outer regions. The method/system establishes a target toner concentration for pixels within the trap area based on toner concentrations of the abutting objects and corrects the target toner concentration to account for irregularities of the outer regions of the trap area to produce a corrected toner concentration for pixels in the trap area. The method/system performs this correction by first empirically testing the printing engine to establish a lookup table of correction values of the outer regions prior to a printing operation. Then, during the printing operation, the method determines a size relationship (weighting) between the central region and the outer regions for the trap area and calculates the corrected toner concentration.
Abstract: An image forming method including (a) providing a reimageable medium comprised 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, wherein the reimageable medium is prepared by a s

Abstract: An image-forming apparatus includes multiple sheet discharge trays arranged on a downstream of a fixing unit in a layer structure, and multiple sheet-receiving units provided corresponding to the multiple sheet discharge trays arranged in the layer structure. Each of the sheet-receiving units respectively includes a climbing slope from a sheet discharge direction start point to a sheet discharge direction end point, and an angle of the climbing slope of a sheet-receiving unit is close to plane, as the sheet-receiving unit is arranged on a further downstream. It is thus possible to provide the image-forming apparatus in which discharged sheets of paper are not piled up on the sheet-receiving unit in a curled state or the discharged sheet does not push out the sheet piled on the sheet-receiving unit.
Abstract: An image processing apparatus performs color conversion processing on an input image based on an attribute of the input image, such as if the image is text or a drawing. An image is reduced, and the color conversion is performed. The color converted image is then enlarged. The image is then output by a computer or stored.
Abstract: An ink set is made up of at least three differently colored phase change inks, for example cyan, magenta and yellow, wherein at least one of the colored phase change inks is a photochromic ink that contains a photochromic material. Upon exposure to activating radiation such as ultraviolet light, the at least one photochromic ink changes to a color different from the color of the photochromic ink prior to exposure to the activating radiation.

Abstract: Video recordings of meetings and scanned paper documents are natural digital documents that come out of a meeting. These can be placed on the Internet for easy access, with links generated between them by matching scanned documents to a segment of the video referencing the scanned document. Furthermore, annotations made on the paper documents during the meeting can be extracted and used as indexes to the video. An orthonormal transform, such as a Digital Cosine Transform (DCT) is used to compare scanned documents to video frames.
