Abstract: A method for producing, or training, a set of character templates uses as the source of training samples an image source of character images, called glyphs, that are not previously segmented or isolated for training. Also used is a labeled glyph position data structure that includes, for each glyph in the image source, a glyph image position in the image source associating an image location of the glyph with a character label paired with the glyph image position that indicates the character in the character set being trained. The labeled glyph position data is used to identify a collection of glyph sample image regions in the image source for each character in the character set; each glyph sample image region is large enough to contain a glyph and typically contains adjacent glyphs for other characters.

Abstract: In a thermal ink-jet printhead, a set of heating elements are formed in the main surface of a semiconductor chip. Channels are formed within the semiconductor chip underneath each of the heating elements, thereby exposing two main sides of each heating element within each ejector. Because two main surfaces of the heating element are accessible to liquid ink in each ejector, efficiency and thermal characteristics of the printhead are improved.

Abstract: An epicyclic drive train arrangement having a plurality of output drive members which may be selectively driven from a single input drive member. A frame equipped with two pawls is operated by a single solenoid and spring combination. During successive cycles of solenoid operation, a selected pawl engages its mating gear by action of a solenoid plunger rod. The action prevents rotation of the selected gear while the pawl is engaged. The unselected pawl disengages its mating gear thereby allowing it to freely rotate. Multiple epicyclic drive train arrangements may be configured so as to drive a plurality of sheet feeding apparatuses in an electrophotographic printing machine.

Abstract: A system for measuring a percentage of the solids in a liquid developer material is provided. The liquid developer material is received by a liquid developer material application member for application of the liquid developer material to a selected surface. The liquid developer material, when disposed on the developer application member as a film, is characterized by a first value varying as a function of developed mass per unit area (DMA) and a second value varying as a function of film thickness. The measuring system includes: a first sensing system for determining a magnitude corresponding with the first value; a second sensing system for determining a magnitude corresponding with the second value; and a controller, responsive to the first and second sensing systems, for determining the percentage of the solids in the liquid developer material with the determined first and second values.

Abstract: In an array of butted silicon chips, as would be found in a full-page photosensitive scanner, ink-jet printhead, or LED exposure bar, individual silicon chips forming the array each define a planar bevel near the border of a neighboring chip. The planarity of the bevel avoids damage to the chips when the chips are placed in the chip array assembly.

Abstract: There is provided a filter having a member of absorption material between a convex lens and a polygonal mirror. This member of absorption material is formed by coating a thin metallic film. Due to the foregoing, a predetermined transmission factor distribution can be provided. Accordingly, it is possible to correct an uneven distribution of a quantity of light on the photoreceptor caused by a change in F-number in the overfilled optical system, so that the distribution of a quantity of light can be put into practical use.

Abstract: When the name of a resource is inputted to a given context holder, a name analysis unit analyzes the name and a name translation unit converts it into first or second resource implementation representations. A name resolution unit receives the first or second resource implementation representations from each context holder. When the result of conversion is of the second resource implementation representations, the name resolution unit outputs a resource name of a second series or string of resource elements included in the second resource implementation representations to its corresponding context holder. This operation is executed on a chain basis to solve the name. A resource implementation unit outputs a handle for the resource corresponding to the result of name resolution therefrom. A user can obtain access to a virtual resource corresponding to the input name by using the handle.

Abstract: An apparatus and method for producing a halftone image which generates halftone cells based on grayscale image data values. Each of the halftone cells is formed from serpentine dot patterns. The serpentine dot patterns form two separate arcs. The halftone cells are written onto a recording medium to produce the halftone image. Rotation of the halftone cells allows data to be encoded within each of the halftone cells without varying the tone of the image.

Abstract: A plural function sheet interconnect module for serially connecting plural multiple bins printed sheets job separating units, such as mailbox modules, with the output of a printer for feeding printed sheets jobs into selected bins. The printer also has a alternate variably occurring output of purge sheets designated for purging, which purge sheets are variably intermixed with the printed sheets jobs. The interconnect module has a sheet bypass transport for feeding the sheets on from one mailbox unit on to another. The interconnect module also has an integral purge tray for collecting the purge sheets and providing for their removal. The interconnect module further has a selectable shared sheet gating system for gating the printed sheets jobs into the sheet bypass transport and gating the purge sheets into the integral purge tray. The integral purge tray underlies the sheet bypass transport and is pivotably openable for the removal of purge sheets therefrom.

Abstract: A method and system for printing during a low ink condition. The system receives a user override instruction and determines if an amount of available ink is greater than a no ink condition. The system prints a page stored in a memory when the amount of available ink is greater than a no ink condition. The system also deletes a previously printed and stored page from the memory before the system prints the page from memory. After the printing process, the amount of available ink is updated. If the amount of available ink is equal or less than a no ink value, the system prevents the printing of the page in memory and the deletion of the previously printed and stored page in the memory.

Abstract: Cell circuitry in an array on a substrate includes a TFT or other structure with a series of two or more channels and with an intrachannel region between each pair of adjacent channels in the series. Each intrachannel region has a continuously distribution of dopant particles and the distribution of dopant particles in the intrachannel regions together controls reverse gate bias leakage current without significantly reducing ON current. The average dopant density in intrachannel regions can be sufficiently low to ensure that reverse gate bias leakage current is approximately constant across a range of reverse gate bias voltages.

Abstract: An array of light control units has an area large enough to present images for direct viewing. The array also has light control units sufficiently dense that ordinary acuity artifacts are not noticeable in presented images when the array is directly viewed at usual viewing distances by a human with normal vision. Signal circuitry can provide signals to the light control units. The array can present an image that includes M colors, where M is more than three, even though each light control unit can only cause presentation of one of a segment with one of a set of N colors, where N is less than M. Data defining an input image with M colors are used to obtain data defining an output image that is a version of the input image but includes, for each light control unit, a color data item indicating one of its set of N colors. The signal circuitry provides signals to the light control units so that each light control unit presents a segment with the color indicated by its color data item.
