Abstract: An apparatus for coating a photoreceptor substrate, such as a photoreceptor belt or a photoreceptor drum, consists of at least one photoreceptor coating fluid reservoir or diptank. The diptank defines an inlet at one end and a conduit with an orifice at the other end. The conduit includes at least one porous element such as a grid, screen or mesh arranged for suspending a plurality of layers of non-contaminating rounded objects, such as stainless steel or glass beads, in the bottom of the conduit. Photoreceptor coating solution supplied to the inlet is thereby forced to flow through the plurality of layers of beads prior to coating a photoreceptor substrate that is inserted through the orifice. As a result, the uniformity of the coating solution is improved as it coats the photoreceptor substrate, thereby reducing coating defects in the finished photoreceptor belt or drum.

Abstract: The pages of a book being held at least partially open may be sequentially automatically turned over from one side of the book to the other by pivoting an elongated arm from one side of the book toward the other and turning over individual pages with a vacuum head pivoting relative to the elongated pivoted arm about a different pivot axis as the elongated arm moves to reduce undesirable forces on the individual book pages being turned over. The vacuum head may initially pivot to bend the edge of an individual page up away from the book, to aid in page separation, and then subsequently differently pivot to help peel the same page gently away from the vacuum head and flip it over onto the opposite side of the book. This may be assisted by moving frictional belts on the vacuum head.

Abstract: Conventionally, the rendering parameter options are set independently of a document. Each object is rendered independently. For documents having many independent objects, this requires significant computational resources and time. However, many documents have a predominant document type. For such documents, it is often sufficient to identify the document type. Then, predetermined rendering techniques are applied to the objects within that document based on the determined document type. Alternatively, a user may be interested in one type of object to the exclusion of the other types of objects. Accordingly, optimally rendering objects whose quality the user is indifferent to wastes resources. Document type based rendering systems, methods and graphical user interfaces define rendering parameter options for rendering the objects of a document based on an identified document type, irrespective of the object types of that document's objects.

Abstract: System and methods for using a fluid ejection system to distribute fluid drop density of a region between at least two overlapping swaths having pixels on a receiving medium. Using the method, overlapping swaths are stitched together by distributing a fluid ejection pattern between the overlapping swaths within the overlapped region. Because small drops of fluid can be distributed within a single region, the fluid ejection pattern can be controlled and intermediate density regions can be created by distributing the fluid of drops within a region between two fluid ejector heads or between two swaths of the same fluid ejector head. The distribution can be linear or non-linear. Furthermore, overlapping swaths are stitched together by randomly varying a stitch location within the overlapped region. In this case, a stitch location is randomly varied in the slow scan direction.

Abstract: A method and apparatus for preventing or inhibiting effective reproduction of documents such as currency, checks, stock certificates, and any other printed document including a pre-defined security mark printed therein. The subject method and apparatus operate to effect a multi-step review of all digital image data acquired from a printed document to be reproduced for purposes of locating any potential security marks and further examining same for purposes of positively identifying a potential security mark as an actual security mark. If a mark is located and verified to be an authentic security mark, effective reproduction of the printed document will not be permitted and/or other security measures will be taken. A pretest of a mark consists of deleting the fine line patterns that may be printed on top of the mark by smoothing the data in an averaging process, and then determining the difference between the density of the darkest and lightest pixels in the area.

Abstract: A liquid developing device comprises a storage tank, a concentration sensor, a level sensor, a concentrated-ink supply pump, a carrier supply pump, an ink discharge pump, and a controller. The storage tank stores ink, including toner and carrier, for developing a photoconductor. The concentration sensor measures a concentration of ink to be supplied to the photoconductor. The level sensor measures the amount of ink stored in the storage tank. The concentrated-ink supply pump sends concentrated ink to the storage tank. The carrier supply pump sends carrier to the storage tank. The ink discharge pump discharges excessive ink from the storage tank. Based on measurement value and amount from the concentration tank and the level sensor, the controller controlls the concentrated-ink supply pump, the carrier supply pump, and the ink discharge pump, so that the concentration and amount of ink stored in the storage tank is retained at a predetermined level.

Abstract: A sheet material for use in a gyricon display in which a rotatable element, which has a portion which is capable of being permanently magnetized may be oriented to experience either an attractive force or a repelling force between itself and another magnetized element. The attractive force between the element and the pad serve to latch the element in place and prevent unwanted display changes from taking place while the repellant force serves to trap the element in place for the same reasons. The element may be constructed to be either cylindrically or spherically shaped. Further, the sheet material may also contain soft magnetic material pads which may be arranged to provide multiple latching states as desired.

An inner surface of each of the first and second reservoir is parabola shaped.

Abstract: A method for determining points of change or novelty in an audio signal measures the self similarity of components of the audio signal. For each time window in an audio signal, a formula is used to determine a vector parameterization value. The self-similarity as well as cross-similarity between each of the parameterization values is then determined for all past and future window regions. A significant point of novelty or change will have a high self-similarity in the past and future, and a low cross-similarity. The extent of the time difference between “past” and “future” can be varied to change the scale of the system so that, for example, individual musical notes can be found using a short time extent while longer events, such as musical themes or changing of speakers, can be identified by considering windows further into the past or future. The result is a measure of the degree of change, or how novel the source audio is at any time.
