  • Patent number: 8713159
    Abstract: A monitoring apparatus for monitoring communication configurations of a plurality of client devices connected to a server, the monitoring apparatus includes: a processor for controlling the communications between the client devices and the server in accordance with a process including: receiving from each of the client devices communication condition information and storing latest communication condition information of each of the client devices; determining at a time interval whether any of client devices became incapable of communication with the server by checking the latest communication condition information of each of client devices; and upon detection of at least one of the client devices for which obsolete communication condition information is stored, issuing a notice indicating that the at least one of the client devices are incapable of communication with the server.

  • Patent number: 8595140
    Abstract: Modified firmware is registered and controlled, and, when a download request is received from a terminal device, unupdated firmware is determined and downloaded to the terminal device. User identification information obtained from the download request is acquired, and, if the user identification information matches the user identification information of another terminal device that is already carrying out download, the download to the terminal device that output the download request is stopped. Even when the user identification information matches the user identification information of the other terminal device that is already carrying out download, if it is determined to be a download request by an operator operation, stopping the download is cancelled so as to execute the download, and a forcible termination notification is transmitted to the other terminal device that is already executing download so as to interrupt the download thereof in the process.

  • Patent number: 8578220
    Abstract: An information processing system includes an electronic device and an information processing unit. The electronic device includes a fault detection unit; a data generating unit for generating, as data, the content of the detected fault; a data dividing unit for dividing the generated data into plural division data in the case where the data exceeds a predetermined capacity; a data compression unit for compressing each of the plural division data; an identification information adding unit for adding identification information to each of the plural compressed division data; and a data transmission unit for transmitting the plural compressed division data with the identification information. The information processing unit includes a data receiving unit for receiving the plural compressed division data, and a data restoration unit for restoring the plural compressed division data into original data based on the identification information.

  • Patent number: 8037172
    Abstract: An operation monitoring apparatus monitors statuses of plural monitoring target apparatus connected to a network, by sending a connection confirmation mail, via a notification server located on the network, receiving the connection confirmation mail and an operation confirmation mail sent from each monitoring target apparatus, storing a scheduled transmission time of a next operation confirmation mail contained in the operation confirmation mail, as part of apparatus information of the monitoring target apparatus and judging, using the scheduled transmission time, whether the next operation confirmation mail has been received. The judgment is not made if a latest connection confirmation mail sent from the operation monitoring apparatus itself has not been received.
