Abstract: The present invention is a system for utilizing a printable, yet unobtrusive glyph or similar two-dimensionally encoded mark to identify copyrighted documents. Upon attempting to reproduce such a document, the glyph is detected, decoded and used to accurately collect and/or record a copyright royalty for the reproduction of the document, or to prevent such reproduction. Furthermore, the glyph may also include additional information so as to enable an electronic copyright royalty accounting system, capable of interpreting the encoded information, to track and/or account for copyright royalties which accrue during reproduction of all or portions of the original document.

Abstract: A thermal ink jet printhead has a flow directing one-way valve for reducing back-flow directed forces generated by the droplet ejecting ink vapor bubbles, so that most of the bubble generated forces are used to eject ink droplets from the printhead nozzles. The one-way valve is provided by patterning the etch resistant mask to form a flap located at a predetermined position along the ink channels between the heating elements and reservoirs, which is activated by bubble generated forces directed in the opposite direction from the printhead nozzles.

Abstract: A xerographic copying/printing machine in which the photoreceptor has a row of discrete image marks along one side margin, a CCD type array spaced opposite to and aligned with the row of photoreceptor marks to provide successive blocks of image signals representing the instantaneous pattern of marks viewed by the array on each scan, a light bar spaced opposite the other side of the photoreceptor and aligned with the array for illuminating the array sensors through the marks, and a circuit for converting the image signal output of the array to clock signals representative of photoreceptor speed and position.

Abstract: A system for enhancing the use of digitized documents as information transmitting and storage objects in connection with an electronic printer having an image input scanner for scanning documents and converting the image content to image signals.
