Publication number: 20150280987Abstract: In a multi-tenant information processing system, when initially constructing a tenant, design items depending on the tenant are specified for each device constituting the tenant, and design values of the design items are calculated without overlapping with those of other tenants. In a tenant design item management table, the design items set for the devices and information indicating whether the design items depend on the tenant, are stored for each device. In a design algorithm management table, calculation formulae for making the design values to be different for each tenant are stored corresponding to the design items. A tenant design unit refers to the tenant design item management table, specifies the design items depending on the tenant among those corresponding to the devices constituting the tenant, calculates the design values of the design items according to the calculation formula, when initially constructing the tenant.Type: ApplicationFiled: June 12, 2015Publication date: October 1, 2015Inventors: Yoshiko YASUDA, Yosuke HIMURA, Hideki OKITA, Mariko NAKAYAMA

Patent number: 9137118Abstract: To identify a logical topology of each virtual network among logical topologies of a plurality of virtual networks configured in physical devices. A management server includes a controller for managing logical topology information of all virtual networks each of which includes a plurality of virtual resources configured in a plurality of physical devices coupled to a network; wherein the controller: searches the logical topology of all the virtual networks from the entire virtual network based on the information of branch point resource which is a kind of virtual resource for mutually coupling the plurality of virtual networks and constitutes a branch point for each virtual network; extracts a series of virtual resources that terminates at the branch point resource; and identifies the series of extracted virtual resources as a partial topology, which eventually represents the topology of a virtual network inside the entire virtual network.Type: GrantFiled: December 20, 2012Date of Patent: September 15, 2015Assignee: Hitachi, Ltd.Inventors: Yosuke Himura, Yoshiko Yasuda, Mariko Nakayama

Publication number: 20140317313Abstract: In a network where network address translation (NAT) has been introduced, a problem occurs in which, when an IP host operating in a network is automatically categorized with automatic IP host discovery using an ARP cache, a plurality of IP hosts with the same IP address are recognized as one IP host by NAT. To resolve this problem, a network management server specifies network sub-topology on the basis of topology information, public addresses translated by NAT, and IP host corresponding relationships.Type: ApplicationFiled: July 19, 2012Publication date: October 23, 2014Applicant: HITACHI, LTD.Inventors: Hideki Okita, Yoshiko Yasuda, Mariko Nakayama, Yosuke Himura, Kazuma Yumoto

Patent number: 8475395Abstract: A method is provided for collecting a small blood sample by painlessly puncturing a finger. When the skin of a human being is punctured by a needle or another device at the depth that does not exceed 0.5 mm, pain accompanying the puncture is diminished or decreased. Regardless of an error in the depth of the puncture, the depth of puncture must not exceed this depth. The puncture site is located on the dorsal surface of a finger, in the area from the finger joint (IP joint of thumb, DIP joint of fingers other than thumb) to the proximal nail wall and the area extending from the proximal nail wall to the lateral nail wall.Type: GrantFiled: February 12, 2004Date of Patent: July 2, 2013Inventors: Toru Nakayama, Mariko Nakayama, Masafumi Nakayama, Takayuki Nakayama

Patent number: 8345668Abstract: The video receiving device delivers reproducible video streams by synchronizing video images. The video delivering device determines the delivery time for each RTP packet based on the time information for plural video streams corresponding to plural contents, adds the determined delivery time (timestamp) to each RTP packet, and delivers RTP packets by using the counter common among plural contents. The video relaying device corrects the transfer timing for RTP packets based on the counter common among plural contents and the delivery time (timestamp) and sends them to the video receiving device. The video receiving device plays back the video images from the received RTP packets.Type: GrantFiled: January 19, 2010Date of Patent: January 1, 2013Assignee: Hitachi, Ltd.Inventors: Mariko Nakayama, Toshiyuki Odaka

Publication number: 20090106807Abstract: Provided is a video distribution system including: a video server for transmitting a plurality of video streams; and a video gateway for transferring at least one of the plurality of the transmitted video streams to a video client. The video server adds a first identifier for identifying whether data of an independently decodable unit included in the video stream corresponds in time to the video stream; and transmits the video stream to which the first identifier has been added. The video gateway specifies, based on first identifiers added to the transmitted plurality of video streams, the data of the independently decodable unit of the video stream transferred after switching in a case where the video stream is switched to another video stream in the independently decodable unit; and transfers the video stream transferred after the switching from the specified data of the independently decodable unit.Type: ApplicationFiled: October 17, 2008Publication date: April 23, 2009Inventors: Toshiaki SUZUKI, Mariko Nakayama
