  • Patent number: 8026455
    Abstract: A connector structure of waterproof and explosion-proof button is provided. A waterproof element completely covers the connecting part of the connecting element. By pressing a first button bar of the waterproof element, a second button bar is driven to depress the button therein. A companion part inside the connecting element is connected and fixed with an explosion-proof element. The connector structure thus achieves the waterproof and explosion-proof effects and has the button function at the same time. The structure solves the problem of having too many elements and too complicated assembly process for achieving the waterproof effect in the prior art. According to the structure, the assembly of the connector structure is simple and both waterproof and explosion-proof effects are simultaneously achieved.

  • Publication number: 20110218968
    Abstract: High performance, enterprise-level data protection system and method provides efficient block-level incremental snapshots of primary storage devices, and instant availability of such snapshots in immediately mountable form that can be directly used in place of the primary storage device. Related systems and applications are described, including an “Enterprise Image Destination” (EID) for backup images; a mirroring technique whereby a replacement physical primary facility may be created while working with a second storage unit as the primary source file system; and a technique for eliminating redundant data in backup images when multiple systems with partially common contents (e.g., operating system files, common databases, application executables, etc.) are being backed up. A number of examples showing “Fast Application Restore” (FAR) with the use of the invention are also provided.

  • Patent number: 8001134
    Abstract: A method of externally sorting large files in a computer system is presented. The contents of the input file to be sorted are investigated in order to identify presorted portions thereof. The presorted portions of the input file as thus identified are incorporated as sorted strings into an external sortwork file, by rearranging directory information rather than physically transferring data. If merging is necessary, the data may then be merged by a procedure wherein blocks of sorted data to be merged are incorporated into an output (sortout) file, by rearranging directory information rather than physically transferring sorted blocks to the sortout file. As a result of the process, portions of sorted data incorporated into the sortout file may physically remain in external storage space allocated to the input file, and/or in external space allocated to sortwork, thereby eliminating or reducing reading and writing from disk during sort-merge processing.

  • Publication number: 20110181563
    Abstract: A display apparatus and the driving method thereof are provided. The display apparatus includes a display panel and a gate driver electrically connected to the display panel. The display panel has N scan units. Here, N is a positive integer, and each of the scan units has a first scan line and a second scan line. The gate driver provides N gate control signals to the scan units. The i-th gate control signal corresponds to the i-th scan unit, and i is less than N. When the i-th gate control signal and the (i+1)-th gate control signal are simultaneously enabled, the pixel elements corresponding to the first scan line and the second scan line of the i-th scan unit are simultaneously scanned. When the i-th gate control signal is enabled, the pixel elements corresponding to the first scan line of the i-th scan unit are scanned.

  • Publication number: 20100257328
    Abstract: Methods and software for “hot migration” of data an original storage unit for a target system to destination storage unit. In one embodiment, a virtual storage device is provided, having a control block mapped to both the original storage unit, as well as to the destination storage unit. The target system is stopped, the virtual storage device is substituted for the original storage unit, and the target system is restarted. The virtual storage device directs requests to the destination storage unit, and fulfills read requests from whichever of the two storage units has a valid copy of data requested (depending, e.g., on whether the data is as yet unchanged, has been re-written, or has been copied, during the migration process). Unchanged data blocks are copies from the original storage unit to the destination storage unit. The target system is stopped, the virtual storage device is disconnected from the target system, and the destination storage unit is connected in its place.
