  • Patent number: 9103951
    Abstract: The present invention provides a light guide plate and a method and a mold for manufacturing the same. The light guide plate comprises at least one incident surface, an exiting surface and a bottom surface, the exiting surface and bottom surface being disposed facing to each other and both being connected to the incident surface, the light guide plate having a cavity formed therein, wherein light incident from the incident surface exits the exiting surface after refracted and/or reflected by the cavity. With the light guide plate, light energy loss can be reduced and brightness of pictures can be improved.

  • Publication number: 20150189019
    Abstract: A method and apparatus for managing network attached storage that includes detecting frequency of access from a client to a data item that is in a first server in the network attached storage, a global namespace of the network attached storage indicating an access address for accessing the data item, the access address including a first address of the data item in the first server; in response to the frequency being higher than a predetermined threshold, copying the data item from the first server to a second server in the network attached storage which is proximate to the client, so as to form a data image; and updating the global namespace so as to add to the access address a second address of the data image in the second server whereby the data access efficiency of the network attached storage can be considerably improved.

  • Publication number: 20140304299
    Abstract: The present invention relates to a method and apparatus for data management in multi-tenant distributive environment. According to the embodiments of the present invention, a tenant-specific virtual metadata server may be created and registered with a task manager in a job processing system. The virtual metadata server provides a tenant-specific logical file system namespace. Any access to tenant data will be performed via the virtual metadata server. In other words, such virtual metadata server acts as an interface between a tenant terminal and an entity file system. In this way, it may effectively realize isolation of tenant data and enhance data security. Moreover, by using a virtual metadata server rather than physically isolating user data, the embodiments of the present invention may guarantee the efficiency of data sharing while improving the data security.
