Abstract: A system and method for compressing and decompressing image data. The system and method reformats the data by interleaving, before it is sent to the compressor. The step of interleaving uses raster scan lines, taking N raster lines at a time and reformatting the data so that the first bit of the first N scan lines form a byte. This is continued for N bits. The data is then sent to a byte/text oriented compressor. After decompressing the data using byte/text oriented decompressors, the data is sent through an inverse binary data reformatter to un-interleave the data and return it to its original binary format.

Abstract: Systems and methods for indexing and searching the inner structure of a string over a language having a vocabulary and a grammar using bit vectors. The index preserves the inner gramatical structure of the string while allowing for a fast search. A single search provides immediate access to every level of a document, without having to re-search a single string to determine which sub-parts of that string match the search string. When a string is indexed, the index maintains a compositional representation and the grammatical relationship between the elements of the vocabulary according to the language. The string is then indexed on different levels by disregarding some of the grammatical relationships of component levels.

Abstract: An in situ system and method for setting the charge voltages in a dual recharge color photocopier device includes a calculating an optimal DC grid voltage for each DC charging device of the dual recharge photocopier device. With the AC charging devices off, the photoreceptor belt is advanced to the first color station at a uniform residual voltage level. The DC charge device for the first color station charges the photoreceptor belt to a uniform voltage level. An non-contact voltmeter measures and stores the value read from the photoreceptor belt. An exposure device at the first color station exposes a portion of the photoreceptor belt to be read by the voltmeter at the next color station. The process continues through each color station, reading the voltage level of the portion of the photoreceptor belt exposed at the previous color station until voltage readings have been obtained for each color station.

Abstract: A user-specific change highlighting system and method keeps track of which version of an information object, such as a document, was last viewed by or downloads to the user. When a user reads or downloads a new version of the document, the system and method checks whether the current version is different from the last-viewed version. If the document has changed, the present invention uses, for example, color, font or some other technique to highlight the changes that have been made to the document.

Abstract: A diagnostic routine for determining the cause of color non-uniformity in a full color image forming device, by selecting a substation of one print station and using it in combination with a substation from another print station, while functionally omitting the intervening substations. The charge setting on the charge substation is adjusted to compensate for the increased distance between the charge substation, and the developing substation in this method.

Abstract: Current density to copy substrates of varying widths if monitored and controlled in the electrostatic transfer unit of an electrostatic reproduction device. Current density through a copy substrate is appropriately adjusted to compensate for the presence of end leakage current effect to a receptor. Voltage supplied to a current generation unit in an electrostatic transfer unit is controlled independent of the characteristic properties of the copy substrate. Image reproduction quality is maintained in an electrostatic reproduction device even as the width of the copy substrate changes and in the presence of end leakage current effect.

Abstract: A multi-stage fusing system for fixing toner images to copy substrates of various weights has a primary fuser and a secondary fuser in series with the primary fuser. Various weights of print substrates may have toner images fixed thereon by the primary fuser. The various print substrates are then transmitted to the secondary fuser or directly to a finishing area. The secondary fuser is designed specifically for heavier weight substrates and a bypass paper path is provided for allowing lighter weight substrates to bypass the secondary fuser.

Abstract: Systems and methods for deskewing a substrate with at least one of a first substrate supplying member and second substrate supplying member that supplies substrates to a chamber that receives the sheet supplied from both the first substrate supplying member and the second substrate supplying member.

Abstract: Defects in an image forming system may give rise to visible streaks, or one-dimentional defects in an image that run parallel to the process direction. One known method for compensating for streaks introduces a separate tone reproduction curve for each pixel column in the process direction. A compensation pattern according to this invention has alignment marks before and after a halftone compensation region. The alignment marks provide alignment between the printer pixel grid and a scanning pixel grid. The line width of each alignment mark and the gray level in each pixel column of each gray level portion is measured and analyzed to produce a local tone reproduction curve for each pixel column and associated line width. The line widths of the alignment marks can be remeasured to adjust the local tone reproduction curves to compensate for the streak defect when printing.

Abstract: An internal filter includes a lower substrate and an upper substrate. Fluid passages are formed by etching grooves into the surfaces(s) of the upper and/or lower substrates and/or in one or more intermediate layers. The filter pores extending between the fluid passages are formed by etching second grooves that fluidly connect the fluid passages. Two or more sets of the one or two intermediate layers can be implemented to provide additional filter passages and/or pores. Each set can be connected to a separate fluid source and/or a separate microfluidic device. In another internal filter, the inlet and outlet passages and the filter pores are formed on the same upper or lower substrate. The inlet and outlet passages are partially formed in a first step. In a second step, the inlet and outlet passages are completed at the same time that the filter pores are formed.

Abstract: A provably correct computer program can be generated using genetic programming techniques. A desired behavior is used to define a formal specification. An initial population of programs is created where each program has a meaning that can be defined using a formalization technique. A fitness function is applied to measure a distance between the meaning of a program, i.e., its actual behavior, and the specification. Any program having a zero value as the measure of distance between the meaning of the program and the specification is determined to be provably correct. After the fitness of some or all of the programs in the current generation of programs has been computed, a provably correct program has not yet been found in the current generation, mutation and/or crossover techniques are performed on at least some of the fittest individuals in the current generation to create the programs of a next generation.

Abstract: Systems and methods for setting up grid voltage for a tandem pin charging device for charging a photoreceptor in a xerographic printing machine. A charge-generating emitter ratio of a first charging unit is determined and a first grid voltage is set based on the charge-generating emitter ratio of the first charging unit. A charge-generating emitter ratio of a offset voltage is then determined and a second grid voltage is set, based on the determined charge-generating emitter ratio of the offset voltage. A final voltage of a photoreceptor is then compared with a final target voltage.
