Abstract: A system for capturing an image of a document includes an input tray (30) for holding documents (20); an input imaging device (40) that captures an image of a first document in the input tray; wherein the input tray image of the first document is captured as an area image; transmitting the captured input tray image of the first document to an image processor (100); and transporting the first document to an output tray.

Abstract: A method of making a panoramic image includes capturing a first image (30) defining a first overlap region (115) capturing a second image (40), and defining a second overlap region (215). Two points (150, 151) in the first overlap region are identified and a first vector (175) overlap region connecting the two points is defined. Two points (250, 251) in the second overlap region which correspond to the two points in the first overlap region are identified and a second vector (275) the two points is defined. If points in the first vector match points in the second vector, determine if the first and second vectors are parallel. If the vectors are not parallel, rotate the second vector image until the second vector is parallel to the first vector.

Abstract: A method for forming a pixel (20) having a predetermined density onto a sensitized recording medium moving in a length direction energizes a pixel exposure source (14) to begin exposure at the leading edge (34) of a pixel (20) and for a first predetermined time interval. The pixel exposure source (14) is de-energized for a period depending on the predetermined density and on media transport speed, then re-energized at the termination of the period. The pixel exposure source (14) is then de-energized at the end of a second predetermined time interval to terminate exposure at the trailing edge (36) of the pixel (20), whereby spatial dimensions of each pixel (20) are maintained at variable transport speed or density of pixel (20).

Abstract: A modular scanning system (10) consisting of a first scanning unit (11) and a plurality of tethered scanning (13) and digital capture elements (150, 160) providing both sheet-fed, platen, and digitally captured documents and photographs. The first scanning unit (11) includes all the mechanisms necessary to permit sheet-fed scanning of documents. The platen scanner (13) provides a second scanning unit which performs platen scanning of documents on a glass top (26) of the platen scanner (13). Since the platen scanner (13) is detachable, the user has the option to select the platen scanning functionality but with the additional flexibility of selectively mounting or storing the platen element.

Abstract: A dressing for wounds includes a useful material, such as dye or biocide, trapped within or behind a gelatin barrier. On application to a wound, metalloproteinases naturally present in the wound diffuse into the dressing and degrade the gelatin, releasing the trapped material. The released material serves various useful purposes, such as indicating the status of the wound or improving wound healing.
