  • Patent number: 8332398
    Abstract: The present invention provides a database system capable of dealing with dynamic changes in an event that vary continuously with time. A database system outputs a retrieval output from data in response to a user's retrieval request on the basis of a retrieval logic. The retrieval logic is allowed to evolve on the basis of a logical model. This logical model establishes a general relationship which leads results from conditions relating to a group of events that are dealt by a data group. Moreover, a database system optimizes a data structure on the basis of the logical model. The logical model can be transferred in a separated manner from the specific data contents of the data group. Therefore, the logical model can be exported to another database system of the same kind, and also imported from another data base system of the same kind.

  • Patent number: 8237936
    Abstract: A data processing apparatus includes an input portion, an output portion, a plurality of compressing/expanding devices which compress data-to-be-outputted inputted from the input portion and expand compressed data-to-be-outputted, a file memory which stores the data-to-be-outputted compressed by some or all of the plurality of compressing/expanding devices, a data discrimination portion which discriminates whether the data-to-be-outputted inputted from the input portion is data including a small amount of information or a large amount of information, and a transfer controller. In cases where it is discriminated by the data discrimination portion that the data-to-be-outputted is data including a small amount of information, the transfer controller transfers the data-to-be-outputted to the output portion through the plurality of compressing/expanding devices operating in parallel.

  • Patent number: 8149446
    Abstract: A printer (100) for printing based on a print job signal sent from a data processing device (200) registers print job signal sending sources and a message corresponding to each sending source in memory (111, 112). A controller (113) detects whether the sending source of a received print job signal is registered in memory. If the sending source is registered, a messaging unit (110, 111) outputs a corresponding message. Sending sources that are permitted to print can also be registered in memory (111, 112). In this case, the controller (113) detects whether the sending source of a received print job signal is registered in memory, and instructs the printer (110) to print only when the sending source is registered as permitted to print.

  • Patent number: 8015257
    Abstract: Multiple user boxes are created beforehand in the hard disk drive of the MFP. The user specifies his own user box and saves image data therein. If the user extracts the image data from his user box and moves it to a folder on his own personal computer, the MFP 1 detects this action. When this user box is specified during a subsequent reading of image data, the storage destination for the image data is automatically deemed to be the folder on the personal computer to which the image data was previously moved.

  • Patent number: 7999968
    Abstract: The image forming apparatus receives image data based on multiple document images of various sizes and/or orientations. The apparatus identifies areas that are not yet assigned with document images on a single sheet of paper and identifies whether any document image can be laid out in an identified area. In another aspect of the apparatus, a maximum document image size is detected from multiple document images, and a scale factor is calculated to cause the detected maximum size match with the size of the entire area of the paper or an area obtained by dividing the paper into equal parts. In another aspect of the apparatus, a scaling factor is calculated for each document image to cause the size of the particular document match with the size of an area obtained by dividing the paper into equal parts.

  • Patent number: 8001191
    Abstract: When electronic mail with firmware attached is received at a data communication apparatus, determination is made whether it corresponds to firmware data of a write process allowable state. In the case of write process allowable data, the message is downloaded from a mail server to a printer controller. Then, derived firmware is transmitted to an image formation apparatus. A firmware rewrite permission is obtained. When the firmware attached to the message does not attain a write process allowable state, waiting is conducted for reception of write process allowable firmware with the data left in the mail server. As a result, a data communication apparatus is provided that can rewrite firmware appropriately independent of a transmitted and received order of divided firmware.
