  • Patent number: 7648519
    Abstract: A surgical instrument that includes an instrument shaft having proximal and distal ends, a tool disposed from the distal end of the instrument shaft, a control handle disposed from the proximal end of the instrument shaft, a distal motion member for coupling the distal end of the instrument shaft to the tool, a proximal motion member for coupling the proximal end of the instrument shaft to the handle, actuation means extending between the distal and proximal motion members for coupling motion of the proximal motion member to the distal motion member for controlling the positioning of the tool and a locking mechanism for fixing the position of the tool at a selected position and having locked and unlocked states.

  • Publication number: 20080086483
    Abstract: Provided is a file service system in a personal area network (PAN), which can improve accessibility of data by defining a semantic file addressing scheme and its construction mechanism on the network, as well as extensibility of data management, such as an automatic backup and replication, by including two separated layers, i.e. a data access layer and a data replication layer. Accordingly, the file service system in PAN includes a data access layer, which is constructed by using UPnP to automatically build up a semantic file address space over all personal devices in the network and using by WebDAV for file I/Os, and a data replication layer, which is based on an object-based storage device (OSD) protocol and is in charge of an automated data backup and replication, wherein the data access layer and the data replication layer are separated.
