  • Patent number: 8965941
    Abstract: A file list generation device creates, at high speed, a list of added, changed, or deleted file data by acquiring the directory URLs of search target files from a first storage, counting the number of directories in each layer through analysis of the directory URLs, and, based on the result of the counting, determines a dividing policy to divide a scan target directory scanning operation, which is to be performed with a distributed server cluster. Directories of the search target files are divided in accordance with the determined dividing policy, and a snapshot of a current directory tree is acquired.

  • Patent number: 8959049
    Abstract: A technique is provided in which, in a foreign language document in which a space character is provided for separation of words forming a document, it is possible to reliably detect each word separation and reliably reinsert a space character in the separation. It is decided whether adjacent characters are included in the same word (i.e., presence or absence of space) using: decision by an English writing rule, decision by information as to whether there is a space character in source document data; decision by the identification of character string objects including adjacent characters; and decision by a gap between the character string objects including the adjacent characters. It should be noted that it is preferable to make a decision by these processing in order of this description.

  • Patent number: 8851687
    Abstract: An incident angle when illumination light from a position detecting device enters a reflecting surface may be large in some cases. In such cases, the retro-reflection rate of a reflecting surface having a prism structure decreases, leading to a cause of erroneous detection. In order to solve this problem, provided is a reflecting plate including a reflecting surface that retro-reflects illumination light emitted from an optical position detecting device towards the position detecting device that includes a light source, the reflecting plate further including: a surface structure in which a concavo-convex pattern having the same triangle shape in cross-section in a width direction of the reflecting plate continuously appears in a longitudinal direction thereof; and a retro-reflecting layer in which reflecting beads are evenly placed on at least one oblique surface of the concavo-convex pattern.

  • Publication number: 20140241568
    Abstract: A digital watermark embedding system generates a watermarked image by providing one or more specific regions in an image, each specific region including two or more base regions symmetric with respect to the centroid, and by embedding a watermark in the image while avoiding the specific region. Further, a digital watermark detecting system detects a watermark in a region other than the specific region, by detecting the shape of the specific region in which no watermark is embedded, calculating the centroid position of the specific region as a centroid, and correcting geometric transformation of the image based on the location in the image that corresponds to one or more calculated centroids.

  • Publication number: 20140201332
    Abstract: A data collection server includes a load monitoring unit configured to monitor a load on the computer system, and a management unit configured to, based on a result of the monitoring, determine a content of a transfer process of data executed at one of servers and transmit the determined content of the transfer process of data to the one of the servers. The management unit determines a type of the transfer process applied to the one of the servers, generates a process subject data list indicating a list of data to which the transfer process is applied out of the data transferred to the data collection server based on the determined type of the transfer process, and determines the content of the transfer process applied to the one of the servers based on the determined type of the transfer process and the generated process subject data list.

  • Patent number: 8726262
    Abstract: The present invention provides a firmware update process capable of realizing both recovery from an interruption of update and saving of a capacity of nonvolatile memory used for backup and storing difference data. Thus, intermediate data is included for always holding a status of firmware in rewriting in addition to the new and old firmware. In a case of updating all blocks configuring the firmware in an arbitrary order, the process successively compares blocks of the intermediate data and new firmware with each other; calculates an address of data for recovery from an interruption of update and a backup capacity required therefor; extracts difference data to be distributed, calculates a capacity thereof and creates an update procedure; and derives a processing order whose total of the backup capacity and the difference data capacity is the minimum (see FIG. 2).

  • Publication number: 20140122175
    Abstract: A device is provided that predicts in advance a farm that will be liquidated due to farm retirement or finds a renter of the farm. CPU 50 acquires determination timing. This determination timing may be acquired from one stored in advance or may be acquired externally. CPU 50 calculates age of each farmer at the acquired determination timing based on age information that is included in basic information. CPU 50 determines whether or not the age of the each farmer at the determination timing is a specified age or higher. CPU 50 predicts whether or not the each block will be a liquidated farm based on a determination result of the age determination means, information on presence or absence of a successor, and information on presence or absence of intention to expand about the farmer of the each block. CPU 50 outputs the block that is predicted as the liquidated farm and the block that is not predicted as the liquidated farm by the liquidated farm prediction in a distinguishable manner from each other.

  • Publication number: 20140108087
    Abstract: A server system generates one thread with respect to a request for a process, and at the time, a thread local storage that is a dedicated area in which data used for the thread is stored is secured on a main storage device. Log tracking information that can uniquely identify output of a log from the start of output of the log to the end of output of the same is held in the thread local storage during a process of a session ID, a user ID, and a sequence number. When the log is output, the log tracking information is added to the log data to be output to an auxiliary storage device.
