Abstract: A method and apparatus for measuring substrate bending stiffness and thereby basis weight on a real time basis. Provided is a corrugator having a plurality of parallel ribs, with one or more sheets of the substrate provided below the corrugator wherein a predetermined gap exists between a topmost sheet of the sheets and the corrugator. A vacuum is applied between the corrugator and the topmost sheet, wherein the vacuum is sufficiently large to raise the topmost sheet, thereby deflecting and bending it into a profile corresponding to the arrangement and size of the corrugator ribs and bending stiffness of the substrate. One or more sensors are provided for measuring the deflection of the topmost sheet. The vacuum, an air knife output and/or a fluffer output are then adjusted according to predetermined rules and the measured deflection.
Abstract: A printing system includes intelligence for balancing throughput, image quality and memory requirements. The printing system includes intelligence for determining whether to print a page in an interleaved mode or in a single page mode. Color pages containing poorly compressed color separations are printed in a single page mode so as to ensure that all of the color separations of the page may fit into the available memory and that system throughput is sufficient. The pages that are not printed in an interleaved mode are printed in a single page mode. The resolution of color data contained in a page that is to be printed in a single page mode may be reduced to fulfill system throughput and memory requirements.

The surface emitting laser has an active layer region composed of an active layer and upper and lower spacer layers deposited on both sides thereof and reflection layers deposited on both sides of the active layer region, an upper reflecting layer deposited on the upper spacer layer of the active layer region, a lower reflecting layer deposited on the lower spacer layer of the active layer region, and a secondary cavity formed by a first mode control layer and a second mode control layer placed on the periphery of the region of emission of the laser beam at the upper reflecting layer.
Abstract: The command embedding systems and methods enable embedding control signals into standard video signals during recording. Specifically, a user selects a mode of operation of the command signal embedding system. Based on the selected mode, control signals are either manually or automatically embedded in a video signal as the video signal is recorded. The control signals may include, but are not limited to, commands that identify the state of the video camera or the environmental conditions surrounding the video camera or commands that tag key frames in the video signal. Once the control signal is received and embedded, the embedded control signal may be recorded, for example, to facilitate further editing, or may be directly televised or broadcast with further manipulation in mind.

Abstract: An airtight elastic cap of an ink-jet recording head and a storage container employing the airtight elastic cap provide high airtightness between a nozzle face and the airtight cap and minimizes ink leak from the recording head even when the head is mounted or dismounted, or when a storage environment changes suddenly. The airtight elastic cap includes a body and an inside wall provided inside thereof. A portion of the wall defines a first space and another portion defines a second space positioned continuously to a center of the first space. The storage container includes a container body that houses the ink-jet recording head and the airtight elastic cap, placed within the container body, that abuts against and protects an ink emission face of the ink-jet recording head while the ink-jet recording is housed.
Abstract: A wire tensioning apparatus and method tensions one or more wires by moving the tensioning function from a wire module to an apparatus external to the wire module. Externally to the wire module, a wire is attached to a fixed end and a movable end. Tension is placed on the wire, and the tension in the wire or the vibrational frequency of the wire is detected and compared to a desired value. If the tension in, or the vibrational frequency of, the tensioned wire does not correspond to the desired value, the tension is further adjusted until the desired value is met. Once the desired tension or the vibrational frequency is met, the wire is secured in the wire module in order to maintain the achieved tension and/or vibrational frequency.

Abstract: A simplified user interface for an image database management system is described. The interface provides a menu driven system for generating a search query. A remote server generates a result containing images that satisfy the search parameters in the query. The interface then displays the images in the result as simulated slides. A user organizes the simulated slides for a presentation by manipulating the simulated slides. The slides may be manipulated on a simulated light table or by placing the slides in a simulated slide carousel. The slides may be freely transferred among the light table, slide sleeve, and slide carousel. Handling images as simulated slides on equipment familiar to the user substantially reduces the time needed to learn how to use the user interface.

Abstract: Image editing method and apparatus which facilitate image editing operation and improve the efficiency thereof by enabling selective use of many editing histories or command strings, used in the past, with ease. A command string used in an editing period for one image is registered as a macro, in correspondence with associated information related to the edited image. When the next image is edited, associated information of registered command strings are displayed, as buttons, in list form. A user can discriminate the contents of the command strings and can visually discriminate a command string appropriate to the currently-edited image by observing the associated information. In response to the user's button selection operation, a corresponding command string is applied to the currently-edited image.
Abstract: A method includes generating a first set of image information representative of a first portion of the multiple page image, the first set of image data corresponding to a first page of the multiple page image. The method also includes generating alignment indicia image information relating to the first portion of the multiple page image. The method further includes generating combined image information comprising the first set of image information and the alignment indicia image information.
Abstract: A system processes a color image. A high-resolution cache stores high-resolution data. A low-resolution memory, electrically connected to the high-resolution cache, stores low-resolution data. The low-resolution memory is capable of storing at least as much data as the high-resolution cache. An image processor, connected to both the high-resolution cache and the low-resolution memory, receives sequential segments of low-resolution and antialiased image data. As the image processor receives a current segment of the image data, the image processor either 1) transmits the current segment of image data to the low-resolution memory or 2) transforms the current segment to high-resolution data and transmits the high-resolution data to the high-resolution cache.
