Abstract: The invention relates to an apparatus (10) and a corresponding process for identifying an object (20) with an article dependently upon a piece of barcode information detected from a barcode (30) with which the object (20) is identified. Here a number of article numbers are stored in a memory (60) which are assigned, on the one hand, to a number of articles and on the other hand to a number of different article number types. According to the invention, the piece of barcode information detected is compared with article numbers stored in the memory (60) dependently upon a specified sequence of article number types. In the case of the piece of barcode information detected corresponding with one of the stored article numbers, the object (20) is identified with the article assigned to this article number.
Abstract: A print head mounting assembly and a method of mounting and positioning a print head on a print head carriage framework suitable for mounting in a printing system includes a print head positioning device for receiving a print head, and a print head mounting tile having a mounting surface for mounting the print head positioning device. The print head mounting tile is adjustably mounted on the print head carriage framework such that it provides a mounting surface for the print head positioning device that is level with a reference printing surface, when the print head carriage framework is mounted in the printing system. The print head positioning device is adjustably mounted on the print head mounting tile such that the print head, being received in the print head positioning device, is accurately positioned on the mounting surface of the print head mounting tile.

Abstract: A receiver table (1) is provided for holding a receiver in a digital printer using a shuttle (2) carrying the printheads (3), e.g. an ink-jet printer, which is divided in small table segments (5) of which height and orientation can be adjusted. By adjusting the segments (5) the table (1) can be deformed to obtain a constant receiver-printhead distance even if the guidance of the shuttle (2) has deviations or exhibits bending during shuttling. Table segments (5) are preferably mounted on a deformable table support (13). The receiver-printhead “throw distance” can be calibrated by measuring the distance profile and adjusting adjustments screws or bolts to align the table segments (5) to the ideal printing distance.

When restarting the recording, it is resumed from the interrupt position.
Abstract: A method reads out X-ray information stored in a storage phosphor layer where an X-ray picture is obtained and made up from a number of pixels. The method includes the steps of: irradiating the storage phosphor layer with a stimulation light beam which is moved along a line over the storage phosphor layer to stimulate the storage phosphor layer into emitting emission light; collecting emission light emitted from the storage phosphor layer, and converting the emission light collected into a corresponding detector signal S; deducing a number of detector signal values D from the detector signal S, where the number of deduced detector signal values D is greater then a predetermined number of pixels of the X-ray picture along the line; and deducing a picture signal value B for each pixel of the X-ray picture along the line from at least two of the detector signal values D.

This representation is processed. Next the inverse of the transformation is computed and the result of the inverse transformation is removed from the image signal.
Abstract: The present invention provides new intermediate compounds enabling the preparation of N-meso substituted cyanine, merocyanine or oxonole dyes wherein the N-meso substituent comprises electron withdrawing groups and wherein such N-meso substituents are introduced at the intermediate level. These intermediates enable the formation of dyes having in the meso-position N-substituents comprising electron withdrawing groups without the need for further derivatization of the meso-substituent at the dye level.

Abstract: A digital image signal is decomposed into a multi-scale representation comprising detail images and approximation images. Translation difference images are computed by subtracting an approximation image at scale s and a translated version of that approximation image. The values of the translation difference images are non-linearly modified. An amplification image is computed at least one scale as the ratio of a first image being computed by combining the modified translation difference images at the same or smaller scale and a second image created by combining unenhanced translation difference images at the same or smaller scale. Next, an enhanced multi-scale detail representation is computed by modifying at least one scale the detail image according to the amplification image at that scale. An enhanced image representation is computed by applying a reconstruction algorithm to the enhanced multi-scale detail representation.
Abstract: A system and method for managing the archival and retention of data in a multiple-node PACS network. Data is distributed among network nodes such that a secondary node will not delete a received image study it has received from a primary node if the primary node is an originating source. Instead, the secondary node will execute data retention. Data retention is achieved by including a delete retention attribute within the metadata associated with the received image data on the secondary node and requiring that the secondary node enforce data retention if a data retention attribute is identified within the metadata stored on the secondary node.
