Patent number: 10209919Abstract: A storage system is able to perform an operation of remote copy from a first storage apparatus to a second storage apparatus. A first control unit transfers summary information of copy target data stored in the first storage apparatus from the first storage apparatus to the second storage apparatus. A second control unit checks the summary information against information stored in the second storage apparatus. The second control unit transfers the checked result from the second storage apparatus to the first storage apparatus. If the checked result indicates matching discrepancy, the first control unit transfers the copy target data to the second storage apparatus and completes the remote copy operation.Type: GrantFiled: April 5, 2016Date of Patent: February 19, 2019Assignee: FUJITSU LIMITEDInventor: Masanori Furuya

Patent number: 9665781Abstract: A moving-body-detecting device is provided with an image capture unit, an image conversion unit, a three-dimensional-object-detecting unit, a turn detecting unit, and a control unit. The image capture unit captures images of the rear side of a vehicle. The image conversion unit performs viewpoint conversion of the captured images into bird's-eye view images.

Patent number: 9235767Abstract: A driving assistance device is provided with a turning state detection unit, an imaging unit, a solid object detection unit and a detection region modification unit. When the turning state detection unit detects that a host vehicle is in a turning state, the detection region modification unit alters a position of a detection region with respect to the host vehicle, or alters a shape or an area of the detection region based on the turning state of the host vehicle. For example, the detection region modification unit sets a shorter region length of the detection region as the turning radius of the host vehicle becomes smaller. Hereby, the region closest to the host vehicle is set, to a limited extent, as the detection regions.Type: GrantFiled: July 17, 2012Date of Patent: January 12, 2016Assignee: Nissan Motor Co., Ltd.Inventors: Osamu Fukata, Yasuhisa Hayakawa, Chikao Tsuchiya, Masanori Furuya
