Publication number: 20230039690Abstract: An object is to provide an image display device capable of correcting a position in a simple manner even when a deviation occurs in position alignment in accordance with movement of a user. The image display device 100 includes a correction processing unit 102 that corrects a deviation when the deviation occurs between image data G and a steel frame T in a field of vision of a user U that occurs in accordance with movement of the user. This correction processing unit 102 acquires a coordinates correction position S that becomes a reference position used for a correction process from the steel frame T1 or the like that is a partial member using design data stored by a storage unit 103 and a self-position of the user U with respect to the steel frame T. The correction processing unit 102 performs correction by performing position alignment of the image data G on the basis of the one coordinates correction position S.Type: ApplicationFiled: January 6, 2021Publication date: February 9, 2023Applicant: NTT DOCOMO, INC.Inventors: Takeo YAMASAKI, Takayuki TAMURA, Yuuki TAKAYA

Patent number: 10481953Abstract: Leakage of detailed information for implementing a virtual server to execute a communication process on virtualization resources is prevented. There is provided a management system (10) included in a mobile communication system (1) configured to include an NFVI (60) which is virtualization resources including a physical server generated by a VNF (70) to execute a communication process, and the system includes a VNFM (30) for managing the VNF (70), a VIM (40) for managing the virtualization resources of the NFVI (60), an orchestrator (20) for managing all the virtualization resources of the NFVI (60), wherein the VNFM (30) includes a retention section (31) configured to retain detailed information for implementing the VNF (70) and a virtual server generation request section (32) configured to request the VIM (40) to generate the VNF (70) using the detailed information.Type: GrantFiled: December 25, 2014Date of Patent: November 19, 2019Assignee: NTT DOCOMO, INC.Inventors: Shigeru Iwashina, Takashi Shimizu, Motoshi Tamura, Tetsuya Nakamura, Hidenori Asaba, Ashiq Khan, Takahiro Yamazaki, Takeo Yamasaki, Joan Triay Marques, David Perez Caparros, Bertrand Souville

Patent number: 10484913Abstract: Provided are a communication control method, a communication control device, and a communication system that can appropriately change a device on a network that executes request processing from a terminal. In a node changing device 10, a sequence monitoring unit 12 detects handover of a UE 90. When the handover is detected, a placement calculation unit 14 acquires node information in the vicinity of a destination and activates nodes in the vicinity based on the node information. In this manner, upon detecting movement of a communication terminal, the node changing device 10 activates nodes in the vicinity of the destination of the communication terminal, and it is thereby possible to prevent an increase in communication delay even when the communication terminal is moved.Type: GrantFiled: June 24, 2016Date of Patent: November 19, 2019Assignee: NTT DOCOMO, INC.Inventors: Takeo Yamasaki, Motoshi Tamura, Shigeru Iwashina, Lan Chen

Patent number: 10140112Abstract: In an update management system including a plurality of servers executing a communication service, a server not connected to a network in which a new version of an application is operated is generated in parallel with a server in which an old version of the application is operated, and old and new correspondence data between an old version server and a new version server is generated and used to execute switching from the old version server to the new version server in a flow on the network and to execute switching-back to the old version server by referring to the old and new correspondence data at the time of occurrence of fault in a new version.Type: GrantFiled: February 13, 2015Date of Patent: November 27, 2018Assignee: NTT DOCOMO, INC.Inventors: Yusuke Takano, Takashi Shimizu, Motoshi Tamura, Hidenori Asaba, Takeo Yamasaki, Masaaki Kosugi

Patent number: 10120710Abstract: A virtual resource management node to seamlessly migrate a virtual machine with less influence on services in an NFV environment. A VIM is a VIM for managing each virtualized resource that is included in an NFV environment including virtualized resources including a physical machine in which a virtual machine having a VNF being a virtualized communication function is implemented, and the VIM includes a switching unit for switching a network flow from a virtual machine of a migration source to a virtual machine of a migration destination, or switching a system between an Active (ACT) system virtual machine of a migration source and a Standby (SBY) system virtual machine of a migration destination.Type: GrantFiled: February 17, 2015Date of Patent: November 6, 2018Assignee: NTT DOCOMO, INC.Inventors: Masaaki Kosugi, Hidenori Asaba, Takeo Yamasaki, Ashiq Khan, Shigeru Iwashina, Takashi Shimizu

Patent number: 4643043Abstract: A vehicle hand brake lever assembly for actuating the vehicle parking brake. The lever assembly includes an axially slidable plunger mounted on a support and having one end connected with a brake actuating member. The plunger and the support have a ratchet mechanism for holding the plunger at the brake applying position. The ratchet mechanism can be released by rotating the plunger about its longitudinal axis. A handle assembly is provided at the other end of the plunger and comprises a handle having a handle shaft. A sleeve fitted to a cylindrical guide member is secured to one of the sleeve and the handle shaft, and a lock member to the other. The lock member is axially slidably received in the guide member and provided with a cam profile for cooperation with a cam profile provided on the sleeve. The lock member is spring biased toward the sleeve so that the cam profiles are normally engaged with each other to thereby maintain the handle shaft at a predetermined relationship with respect to the plunger.Type: GrantFiled: February 9, 1984Date of Patent: February 17, 1987Assignees: Aisin Seiki Kabushiki Kaisha, Toyota Jidosha Kubushiki KaishaInventors: Yohichi Furuta, Takeo Yamasaki, Tomio Tachino, Masayoshi Tanikawa
