    Abstract: Upon receipt of an I/O request instructing storage of data in a storage device 106 from a host apparatus, a storage apparatus 100 selects a de-duplication process method to be applied to the received data, based on at least any of influence on processing performance of the storage apparatus 100 to be performed by execution of a first de-duplication process method (inline method) in which the de-duplication process is performed on the data immediately after the receipt of the I/O request, influence on the processing performance of the storage apparatus 100 to be performed by execution of a second de-duplication process method (post-process method) in which the de-duplication process is performed on the data at later timing, and the size of a temporary storage device 106b to be required for the processing of the data by the second de-duplication process method.

    Abstract translation: 在从主机装置接收到指示存储装置106中的数据存储的I / O请求时，存储装置100基于对处理的影响中的至少任一个选择对应用于所接收的数据的重复数据删除处理方法 通过执行对接收到I / O请求之后的数据进行重复数据删除处理的第一重复数据删除处理方法（内联方法）来执行存储装置100的性能，对处理 通过执行对稍后定时的数据进行重复数据删除处理的第二重复数据删除处理方法（后处理方法）以及临时存储装置106b的大小来执行存储装置100的性能 是通过第二重复数据删除处理方法处理数据所需要的。

    Abstract: A work sequence management device (1) of the present invention is characterized in including: a question processing unit (22) that acquires a question raised by a worker at a site; and a language processing unit (23) that determines whether there is necessity to present, to the worker, an intention of issuing an instruction together with the instruction for the acquired question. Further, the work sequence management device is characterized in further including an intention request unit (24) that generates an intention request for prompting generation of the intention when there is the necessity.

    Abstract: A display system includes a display and a detector configured to detect an orientation of the display. The display system includes a display source image generation unit configured to generate a display source image including a first image and a second image related to this first image; and a visual field image display unit configured to display the first image in a first display region of the display and display the second image in a second display region of the display. The visual field image display unit is configured to set a predetermined fixed region of the display as the first display region when a display mode associated with the first image is a first display mode, and determine the first display region according to the orientation of the display when the display mode is a second display mode.

    Abstract: A video recording device includes: a camera which captures a video of a visual-field direction of a wearer; a connection part which is communicably connected to an external sensor which detects predetermined environment information; a threshold information storage part which stores a threshold indicating an abnormal state of the environment information; a determination part which outputs an abnormality determination signal by comparing detection information of the external sensor and the threshold; a control part which outputs a predetermined control signal to the camera in response to the abnormality determination signal; and a display part which displays output information from the camera and the external sensor. When the abnormality determination signal is output, the control part outputs a control signal for transferring output information from the camera to a predetermined storage part.

    Abstract: Chunks that commonly occur in each content type are aggregated in a first container. To be more specific, a storage device used for content backup is configured with: (1) a memory device that provides a memory region for one or a plurality of first containers used to store first chunks that commonly occur in each content type among chunks extracted from the contents of writing targets, and for one or a plurality of second containers used to store other chunks than the first chunks; and (2) a backup unit that decides whether each of the chunks extracted from the contents of the writing targets is a first duplication chunk duplicating a chunk stored in the first container, and further decides, for only a chunk that is decided not to be the first duplication chunk, whether each of the chunks is a second duplication chunk duplicating a chunk stored in the second container, and then stores only a chunk that is decided not to be the second duplication chunk in the second container.

    Abstract translation: 通常在每个内容类型中出现的块会聚集在第一个容器中。 更具体地说，用于内容备份的存储设备被配置为：（1）存储器设备，其为一个或多个第一容器提供存储区域，所述第一容器用于存储在每个内容类型中通常出现的第一块，提取的块 从写入目标的内容以及用于存储比第一块大的其他块的一个或多个第二容器; 以及（2）备份单元，其判定从所述写入目标的内容中提取的每个块是否是复制存储在所述第一容器中的块的第一复制块，并且还对于仅被决定为不是的块 第一复制块，每个块是否是复制存储在第二容器中的块的第二复制块，然后仅将决定为不是第二复制块的块存储在第二容器中。
