Abstract: What is disclosed is a method for encoding liquid ink with a biomarker which can be traced back to a specific inkjet printer. In one embodiment, an aqueous solution containing a biomarker is combined with a volume of liquid ink. The biomarker comprises a nucleic acid. An ordering of nucleobases forming that nucleic acid has a code sequence. In one embodiment hereof, the nucleic acid is constructed using a code sequence which contains, at least in part, the device specific serial number of the inkjet printer. The encoded liquid ink is added to an inkjet printer and the code sequence encoded in that ink is associated with that particular inkjet printer. The inkjet printer is then used to deposit the encoded ink onto a media substrate. In other embodiments, a fluorescent marker is also added with the volume of liquid ink such that the ink fluoresces under an ultraviolet light.

Abstract: A feeding system in a printing apparatus is disclosed. For example, the feeding system includes a feed roll, a retard roll, a movable arm, a spring and a temperature dependent flexible material. The movable arm is coupled to the retard roll. The spring is coupled to the movable arm. The temperature dependent flexible material is located below the spring to move the retard roll towards the feed roll via the spring coupled to the end of the arm to maintain a nip force applied by the retard roll against the feed roll as a temperature in a location of the printing apparatus changes.

Abstract: A mount for a light emitting diode print bar removably installable in a printer including an open end having a first curved mounting surface and a closed end oppositely disposed relative to the open end and including an opening, the opening having a second curved mounting surface. A projection of the first curved mounting surface substantially coincides with the second curved mounting surface and the light emitting diode print bar is arranged to pivot about the first and second curved mounting surfaces within the mount.

Abstract: Provided is an interactive control device and system including an integrated display. According to one exemplary embodiment, the control device includes a collimated optical fiber optically coupled to a conventional LCD screen including a control image, the control image is projected to a remote face of the optical fiber for viewing by a user. In addition, a tactile control integrated with the collimated optical fiber provided the user with the ability to control a function associated with the control image, whereby the control image dynamically changes based on the user's movement of the tactile control.

Abstract: What is disclosed is a system and method for compensating for side 1 to side 2 differences in a document scanning device. In one embodiment, the present method involves selecting at least one solid area patch printed in at least one reference color of a color space. The scan head of side 1 scans the patch to capture a first set of color values. The scan head of side 2 scans the same patch to capture a second set of color values. A regression method generates a coefficient matrix which minimizes a ΔE color difference metric between the first and second sets of color values. An image processing module associated with the side 2 scanner is programmed with the coefficient matrix and uses the coefficient matrix to adjust a color response of the side 2 scanner to compensate for side 1 to side 2 differences.

Abstract: What is disclosed is a multi-function system which receives media printed with ink having thermo-reactive properties with the ink being visually transparent on that media, and which processes that media such that the ink becomes visually perceptible. One embodiment of the present system comprises an input tray for receiving printed media into a transport path along which the media travels. A cooling element resides in proximity to that transport path for changing a temperature T of the media to T≦TL. A temp-normalizing element is positioned along the transport path downstream of the cooling element for changing a temperature of the media such that the media's temperature T can be normalized back to a temperature range TL

Abstract: A document scanning device includes first and second image sensors spaced along a document path and positioned to scan first and second sides of an input document. A first driven belt is configured to receive the input document directly onto a first surface of the first driven belt and transports the document past the first image sensor, where a first side of the document is scanned. A second driven belt, horizontally spaced from the first driven belt, receives the document after it has been scanned by the second image sensor and transports the document to an output. The device is suited to scanning of a variety of substrates and document sizes, such as normal, small, rigid, or delicate documents as the document path can be substantially straight and provide support for the document during scanning allowing delicate, small or rigid documents to be scanned.

Abstract: A system and method to secure information displayed on the screen of a computing device is provided in which an image to be displayed is algorithmically distorted and thereafter displayed on a display device. To properly view the image, a user must use decoding eyewear which will correct for the applied distortion. The displayed image is thereby rendered unviewable to casual observers and passers-by.
