  • Patent number: 5832455
    Abstract: A user operates a user interface to select a rule for executing the process of a work flow, which is stored in a personal data base or a shared data base, and sends the conditional part of the selected rule as the goal to a query portion. Then, the query portion successively executes the process of the work flow through the computation by the SLD contradiction. When the goal fails in the execution by the computation, the failure goal is transferred as a tapple to the tapple space. The tapple is solved by another query portion, and the result of executing the tapple is returned to the tapple space. If a rule for executing the tapple is not found, the task is processed by man or a user and the result of the processing is entered into the system. In answer to this, the system interprets that the task has been proved to be true, and continues the execution of the work flow process.

  • Patent number: 5832358
    Abstract: A method of ejecting copy sheets from the compiler in a printing apparatus that includes a processing section for transferring a developed image onto a copy sheet and a finishing section with a compiler and a stapler for receiving plural copy sheets to generate a print set. In particular, the level of copy sheets in a compiler tray is sensed, a tag in non-volatile memory indicating a number of allowable extra copy sheets in the compiler is monitored, and a capacity count for sheets to be stapled is referenced. In response, a set of copy sheets may be ejected from the compiler in an unscheduled manner as a function of the level of copy sheets in the compiler tray, the tag in non-volatile memory, and the capacity count for sheets to be stapled. This enables the finisher to complete a set that might have been prematurely ejected or enables the finisher to eject a set before reaching a jam condition.

  • Patent number: 5831649
    Abstract: An ink jet printing system includes an ink jet printhead which has an n-bit code representing a unique characteristic of the printhead formed on a substrate forming a part of the printhead. An n-bit data code is sent from a remote source to the printhead. If the data code matches the code on the printhead, printing operation is initiated. If the code is not matched, the print operation is inhibited.

  • Patent number: 5831747
    Abstract: A method and apparatus for framing an image portion in which a size attribute of the applicable frame is inputted with a user interface and dimensions of the image portion are stored in memory. A processor determines, by reference to the inputted size attribute and the stored dimensions, whether a preselected relationship exists between the image portion and the applicable frame. When the preselected relationship does not exist, the image portion is scaled with an image processing subsystem.

  • Patent number: 5832341
    Abstract: An apparatus, printing machine and method for replenishing an aquatron liquid reservoir in an aquatron charging device. The print media (e.g. paper, vellum, etc.) releases liquid from the print media during fusing. A condenser creates condensate from the liquid released by the print media which is collected in a conduit and transported using air flow into a collection container. This collection container can be the aquatron liquid reservoir, or a separate collection container that pumps liquid to the aquatron liquid reservoir, thus, enabling replenishing the liquid supply of the aquatron liquid reservoir within the printing machine. Sensing devices measuring liquid concentration resistance in the aquatron liquid reservoir and/or the collection container control the liquid level of the reservoir and/or collection container.

  • Patent number: 5831853
    Abstract: Qualitative reasoning for physical systems, and techniques for automatic code generation are used to automatically construct digital controllers/device drivers for electro-mechanical systems. Such construction uses models of the system's components described as finite state machines, to form a configuration space. Transitions of the configuration space are labelled as external or internal and a state of the system is identified as a desired state while other states are identified as undesirable. From this configuration space a controller is generated to drive the system to the desired state while avoiding the undesirable states.

  • Patent number: 5832359
    Abstract: A device and method for measuring the thickness of liquid on an adjustable metering roll. The device comprising a transfer roll that mates with a back-up roll to form a nip through which a sheet passes for wetting a side of the sheet. An adjustable metering roll mates with the transfer roll and has a portion thereof positioned in a liquid filled sump for liquid to be added to an outside surface thereof. An optical sensor is positioned to detect the type of reflected light from the liquid on the outside surface of the metering roll and give off a Go/No Go signal when indicating contact between the metering roll and the transfer roll. The correct liquid thickness is obtained on the surface of the metering roll by further adjsutment of the metering roll.

  • Patent number: 5832504
    Abstract: A system of creating enhanced reports from a computer database or programming language. The system will contain the basic data and some contextual information, which is the description of the type of information contained within the lists of the data file. The enhanced report generator will be sets of instructions which are loaded into the computer, each set of which will contain rules for formatting a report, based on the user inputs, the data, and the data's context. In the event that the context is not sufficient, additional contextual information will be loaded at the time that the enhanced report generator is loaded. The enhanced report generator will be loaded into the system in parallel with the standard report generator that is contained within the computer as a software application, and the user can select one, thus making the use of the enhanced reort generator transparent to the computer.

  • Patent number: 5828933
    Abstract: REaD(Recharge Expose and Develop) electrophotographic printing using additive color toners and inhibited image on image development. Inhibited image on image development is achieved by setting the exposure set points such that exposure losses incurred when imaging through previously developed toner reduces the electrostatic potential for developing over the developed toner, by using a DC corona system during recharging so as to enhance the voltage drop across the previously developed toner(s), and/or by increasing the developed toner mass to increase the thickness of the dielectric properties of the developed toner.

  • Patent number: 5828932
    Abstract: Attributes of an original (image density and discrimination between a color image and a black-and-white image) stopped on a platen glass is read by a reading unit in which light is irradiated upward from a lamp and reflection light is finally read by an image sensor. Next, while carriages of the reading unit are moved rightward, an image of the original is read by the reading unit. After completion of the reading operation, the carriages are held at a position near an image reading end position. Then, the readout original is ejected from above the platen glass, and the next original is transported by an automatic document feeder so as to be stopped on the platen glass. Thereafter, while the carriages are moved leftward, attributes of the next original stopped on the platen glass are read.
