Patent application numberDescriptionPublished
20080307084STORAGE UNIT INFORMATION CONTROL SYSTEM FOR USER TERMINAL - The invention enables the control of the information in a storage unit in a user terminal, prevents data from leaking to unauthorized users and protects information in the user terminal. A management OS manages the input/output to/from a user work OS in the user terminal, identifies a control-triggering condition set by a management server, controls the information in the storage unit storing the user work OS-related information so that information leakage can be prevented, and it also backs up the user work OS-related information to the storage apparatus using the user work OS input/output information.12-11-2008
20080307120INFORMATION SYSTEM AND INFORMATION STORAGE METHOD OF INFORMATION SYSTEM - Provided is an information system for preserving data of a storage device in a computer that repeats the connection to and disconnection from a communication network. The computer acquires data to be written into the storage device and manages the update status of the storage device, transfers the data written into the storage device to the storage controller independent from the writing of data into the storage device when the computer is in a communicable state with the storage controller, and discontinues the transfer of data written into the storage device to the storage controller and manages the transfer status when the computer is not in a communicable state with the storage controller.12-11-2008
20090083432Traffic control system and traffic control method - A traffic control system 03-26-2009
20090125583PRIORITY CONTROL SYSTEM AND METHOD - A priority control system includes a terminal, and a processing server coupled over a network. The processing server has an operation processing sections each of which executes a predetermined process, a communications device, a priority determination section, and a priority assignment section. The processing server also has priority information about priorities to be assigned according to a type of operation processing section. Each of the operation processing sections executes the predetermined process based on a packet, provided by the terminal, and generates screen information with a result of the predetermined process. The communications device transmits screen information with an assigned priority. The terminal receives the screen information transferred by a network device on the network in accordance with the priority, and displays the screen information.05-14-2009
20100082555MANAGEMENT DEVICE AND COMPUTER SYSTEM - A management device connected to a file server providing a computer with file data stored in a storage subsystem, and collects information about access to the file data. In the management device, a log of access to the file data stored in the storage subsystem is collected as access data, and the access data for the same file data is grouped. With such a configuration, a large amount of information about access to the file data can be easily used, and the amount of information can be compressed.04-01-2010
20110066677Network System - A network system including a management device with both a status managing unit for collecting status information on a terminal status and a terminal instructing unit for transmitting a shift start message to the terminal to make transfer data to the server on the basis of the status information collected by the status managing unit. The terminal includes a determining unit for determining data transfer in response to the shift start message, a data transferring unit for transferring the data to the server when the determining unit determines the data transfer, a storage device control unit for erasing the data from a storage device after completion of data transfer, and a thin client shifting unit for causing the terminal to function as a thin client after erasure of data.03-17-2011

20090064298System and Program for Access Control - A system and program for a proxy server that forwards an access request from a client to a data server and forwards response data from the data server to the client. The proxy server includes a means for storing a first address location and an encoding format of the response data. The proxy server also includes a means for receiving a subsequent access request from the client, which includes a second address location encoded by the encoding format. A means is present in the proxy server for comparing the second address location to the first address location to determine if the second address location is related to the first address location. The proxy server also includes a means for decoding the second address location based on the encoding format in response to a determination that the second address location is related to the first address location.03-05-2009
