Abstract: A thermal printhead (26) having a plurality of resistive heat elements (207) receives electrical current from a power supply (201). The current is directed to selected ones of a plurality of heat elements (207) in response to a sequence of data bits corresponding to the image to be recorded. The number of selected heat elements (207) is determined by the current to the printhead (26) or by counting the number of data bits and a signal representative of the number of selected heat elements is produced. The voltage coupled to the printhead (26) is adjusted responsive to the sensed number of selected heat elements to maintain a prescribed voltage across the selected heat elements that is substantially constant independent of the number of selected heat elements.

Abstract: A thermal printer for printing a continuous tone image includes an image signal source (201), a thermal printhead for printing one line of image pixels at a time, and an image signal converter that transforms each line of image signals into print pixels that are applied to the heat elements of the printhead. The image signal converter includes an image memory (207) that stores the set of successive lines of image pixel signals for the entire image obtained from an image source and a memory for storing a subset of the successive lines. A control processor (205) transfers the set of successive image signal lines to the image memory and then sequentially transfers one successive line at a time to the subset memory. The stored subset comprises the line of image pixel signals being converted, a plurality of lines of image pixel signals preceding the line of image pixel signals being converted and a plurality of lines of image pixel signals succeeding the line of image signals being converted. An image signal processor cooperates with the subset memory to modify the image pixel signals of the image signal line being converted in response to the image signals of the line of image signals being converted, the image signals of the plurality of image signal lines preceding the image signal line being converted and the plurality of image signal lines succeeding the line of image signals being converted.

Abstract: In an optical character recognition system, character strokes are automatically enhanced prior to processing by matching the character bit map with a set of templates. Each template has a stripe of thickness W composed of binary ones surrounded by zeroes along a horizontal, vertical, major diagonal or minor diagonal direction. If the template matches a character stroke to a predetermined degree, the stroke is enhanced by increasing its thickness to a predetermined number N of binary ones.

Abstract: Hydrophilic organic colloids such as collagen or gelatin are modified for use in photographic elements such as film or paper, or for use as reagents in automated dry chemical analyzers. The modification comprises reaction of some of the carboxy groups attached to the polypeptide with (i) an amide bond forming agent, e.g. 1-pyrrolidinyl-carbonylpyridinium chloride, and (ii) a di- or triamine, such as piperazine, diethylenetriamine or ethylenediamine. Such modification enables that colloid to react faster with a gelatin hardener such as bis(vinylsulfonyl)methane (BVSM). When coated over an equal amount of unmodified gelatin, and both layers imbibed with BVSM, a modified gelatin layer showed an enzyme resistance greater than that of the unmodified gelatin. This demonstrates that the modified gelatin hardened preferentially. This discovery of a method for differential hardening can be utilized to prepare multilayer photographic elements or multilayer reagents for chemical analyzers that contain one or more layers which are hardened preferentially, i.e. to a greater degree than other layers.

Abstract: The width of each stroke in a character image is reduced one pixel at a time over a series of repetitive cycles until the number of cycles exceeds a predetermined number proportional to the thinnest character stroke observed in the character image. The process is then continued until the character has been skeletonized, but with the added constraint that the existing end point pixels of character strokes are retained.

Abstract: An imagery data mechanism for controllably merging separate, digitally formatted and arbitrarily shaped images eliminates overlap-edge artifacts by gradually blending a paste image (40) along its border (44) with a base image (30), regardless of the shape of the paste image. The mechanism employs a 'feathering' window (50) containing a plurality of neighboring pixel locations over which the pixel values of the paste image are controllably modified to achieve a tapered blending of the two images. Whether the data value for any pixel within the display is to be modified from a given database value will depend upon whether or not that pixel location is both within the paste image and a prescribed distance to the border (44) of the paste image. If the pixel location is not even part of the image, it is effectively masked, so that not only does no feathering take place, but neither the base image nor the paste image contributes to its data value.

Abstract: A device (30) for assuring separation between a receiver member (R) and a dielectric member (12) in an electrostatographic reproduction apparatus (10). The electrostatographic reproduction apparatus includes a dielectric member (12) adapted to carry a developed image, the dielectric member being movable along a travel path in which at some point the direction of travel is changed. Upstream of the change of direction of travel of the dielectric member (12), a mechanism (16) is provided for electrostatically transferring a developed image from the dielectric member (12) to a receiver member (R) movable into register with the dielectric member (12). The separation device (30) comprises an electrically conductive member of sharp edge configuration (30a/30b). The conductive member is located along a line transverse to and coincident with the desired travel path of the receiver member after separation of the lead edge (RL) of the receiver member (R) from the dielectric member (12) at a predetermined distance from the line of separation of the receiver member from the dielectric member as the dielectric member changes direction. Such predetermined distance is sufficient to enable separation of the lead edge (RL) of the receiver member (R) from the dielectric member (12) and approach contact with the receiver member to discharge electrical potential on the receiver member and prevent such electrical potential from effecting re-attachment of the receiver member to the dielectric member.

Abstract: In photographic processing, the chemistry needs to be replenished periodically in order to produce optimum results. Known replenishment systems utilise replenishers in liquid form which are dispensed according to volume. These systems require the use of a pump which is both accurate and relatively inexpensive. Described herein is a replenishment system which uses a weighing system with a series of intermediate containers to dispense replenishment materials. The system comprises a weighing device (2) which has three intermediate containers (11, 21, 31) supported on it. Each container (11, 21, 31) is connected to its associated processing stage (10, 20, 30) by a pipeline (12, 22, 32). Flow of replenisher materials from each container (11, 21, 31) is controlled by respective valves (13, 23, 33) which are interfaced with a computer (3). The computer (3) is also interfaced with the weighing device (2) and monitors the decrement in weight of the intermediate containers (11, 21, 31) so that the exact amount of replenisher materials can be added.
