  • Publication number: 20040080765
    Abstract: In a print server, when page setting is made, a spot color name is extracted from a comment in an image drawing command and image data or a code of a job on a page (page layout) unit basis and a list for a spot color name of each page is generated. After that, a color separating process and an RIP are performed on the page unit basis, raster data of each of colors C, M, Y, and K and corresponding raster data of a spot color name is generated, after that, on the basis of CMYK values designated by the spot color name, the raster data of the spot color is composed with the raster data of each of the colors C, M, Y, and K, and the resultant is output. In such a manner, an overprint of an object designated in a spot color can be reproduced accurately.

  • Publication number: 20040080770
    Abstract: An instruction sheet making section of an instruction sheet editor displays on a GUI icons of services capable of being executed by using a service list sent from a service search server. Further, the instruction sheet making section also displays logic icons of linking processing patterns of the respective services. An instruction sheet making section combines the services provided by one or more service processing sections and makes an instruction sheet, by using service icons and logic icons selected by a user, while referring to and utilizing I/F information sent by the service processing section. Therefore, it is possible to easily combine the services capable of being executed on a network and produce a workflow.

  • Publication number: 20040083389
    Abstract: To deal with user network communication activity which cannot easily and clearly be determined as problematic behavior, a behavior analysis apparatus 14 monitors communication between each user PC 16 in a domain 10 and Internet 20 via a gateway apparatus 12. For example, when there is a monitored item related to information leakage of the user in the detected communication, a weight value corresponding to the monitored item is added to a score concerning a possibility of the user leaking information. Subsequently, the scores are totaled and recorded for each unit of time. The behavior analysis apparatus 14 inputs data of time-series transition of the total value to a neural network which has performed learning for prediction processing, and predicts the possibility of the user's information leak at a time in the near future. When an increasing risk of leakage is predicted, the behavior analysis apparatus 14 communicates an alarm to a security manager.

  • Publication number: 20040079800
    Abstract: The present invention provides a document verification system capable of verifying whether a document is an original at low cost and with ease. A terminal device acquires, as a registered feature vector feature information indicating a feature of a nonreproducible disorder portion in a printing region on a document serving as the original, and stores the registered feature vector on a hard disk via the Internet. A server acquires, as a calculated feature vector the same information as the registered feature vector in a document to be verified as to whether the document is the original, reads out the registered feature vector from the hard disk, compares the acquired calculated feature vector with the read out registered feature vector, and verifies whether the document to be verified is the original on the basis of a result of the comparison.

  • Publication number: 20040083187
    Abstract: A plurality of components are specified to perform a negotiation, where each component is a participant, a coordinator, or both. Each component is provided with a conversion table that maps a set of parameters between invocation patterns instantiated by the participants. Each coordinator is provided with a negotiation graph that it modifies to coordinate its neighborhood of negotiation graphs, and each participant is provided with a negotiation graph that it modifies for each invocation pattern it instantiates. Two message types are sent between components that communicate directly with each other in each neighborhood of negotiation graphs. The two message types are sent between the components to collaboratively mirror their negotiation graphs using their conversion tables in each neighborhood of negotiation graphs so that each participant only views information concerning those aspects in its negotiation graph that relate to the parameters of the invocation patterns it instantiated.

  • Publication number: 20040083186
    Abstract: A negotiation is carried out between a plurality of participants. Each participant defines an invocation pattern. A set of coordinator parameters are attached to each invocation pattern, where the set of coordinator parameters define interdependencies between parameters of the plurality of participants that are shared across their invocation patterns. A graph is constructed to carry out the negotiation of a set of actions to be performed by selected ones of the plurality of participants, with nodes of a first node type that represents a negotiating context or a second node type that represents a decision point. The participants construct the graph with primitives instantiated by the invocation patterns. At least one node in the graph is a decision point that merges two or more negotiation contexts into a single decision point. The single decision point combines values of the parameters from the two or more negotiation contexts.

  • Patent number: 6726313
    Abstract: An ink jet printer is disclosed which, only when ink is to be supplied, supplies ink from a main tank disposed outside a carriage and which can effect the supply of ink stably without the leakage of ink. When it is detected by an ink level sensor that the ink level in a second ink chamber of an ink tank has become lower than a predetermined position, pipes in ports are inserted respectively into slit valves provided in the second ink chamber. Then, by operating a pump, the air present in the second ink chamber is discharged by suction to increase a negative pressure in the second ink chamber, allowing ink to be supplied from a main tank into the second ink chamber. Thus, since the supply of ink is performed by a negative pressure, it is possible to prevent the leakage of ink from the portion where the pipe is inserted into the slit valve.

  • Patent number: 6728419
    Abstract: A method and apparatus for multi-threaded, multitasking processing of image data includes inputting a plurality of image data portions representing one or more images to be processed and putting the first portion of the image data in a memory storage portion. The memory storage portions may be called queues, stacks, address spaces, registers, files, arrays and buffers. While receiving a second portion of the image data, a first portion of the image data is analyzed for the need to be modified by one or more processing methods. Then the image data is modified as necessary by the one or more processing methods while possibly receiving additional image data, and analyzing the second portion of the image data for the need to be modified by the one or more processing methods.

  • Patent number: 6728752
    Abstract: A system and method for browsing, retrieving, and recommending information from a collection uses multi-modal features of the documents in the collection, as well as an analysis of users' prior browsing and retrieval behavior. The system and method are premised on various disclosed methods for quantitatively representing documents in a document collection as vectors in multi-dimensional vector spaces, quantitatively determining similarity between documents, and clustering documents according to those similarities. The system and method also rely on methods for quantitatively representing users in a user population, quantitatively determining similarity between users, clustering users according to those similarities, and visually representing clusters of users by analogy to clusters of documents.
