An expandable vertebral interbody / intravertebral (spinal) body device for insertion into a spinal (intervertebral or intravertebral) space is provided. The interbody / intravertebral body device is expandable from a first circumference to a second circumference through axial compression of segments of the vertebral interbody / intravertebral body device, particularly once the interbody / intravertebral body device has been properly situated within a vertebral space. The interbody / intravertebral body device is characterized by a plurality of axially stacked, individual segments that are provided on a central insertion and deployment rod. Each segment includes a central plate or body to which are pivotally attached plate or leaf structures. Pivoting of the structures provides a collapsed or unexpanded position of the first circumference and an open or expanded position of the second circumference. The vertebral interbody / intravertebral body device may be formed of a bio-compatible radiolucent material. The radial profile of an interbody / intravertebral body device is easily defined by plate or leaf structures of the segments.

Access Control Lists (ACLs) are used to describe the permitted actions (permissions) on protected network computer system resources or objects associated with an client or user identity. An identity may be an individual user or group of users. The actions are used to represent the different access methods available on a particular projected object or resource. A new action grouping mechanism is provided which tags each action with an action group name. The grouping of actions facilitates a larger permission set to be defined in an ACL, whereas action permission indicators can be reused for unique action definitions within various action groups. This effectively extends the finite total number of permissions available within a security system, allows a more descriptive and extensible permission mechanism in an Access Control List, as well as aiding in the simplification of management and definition of security policies.

The present invention provides a method and system for positioning an object with adaptive resolution. The method comprises: dividing a space to be detected into Hot Area and General Area; arranging, according to the positions of Hot Area and General Area, high-resolution positioning signal (US) transceivers and low-resolution positioning signal (RF) transceivers, wherein the detection scope of the low-resolution positioning signal transceivers covers the space and the detection scope of the high-resolution positioning signal transceivers covers the Hot Area; and when the object moving in the space, fusing the detection results from the high-resolution positioning signal transceivers and the low-resolution positioning signal transceivers to determine the position of the object with adaptive resolution. With the system of the present invention, for different areas, the object can be positioned with different positioning resolutions (precisions or granularities). Also, since it is not necessary to use a great deal of high-precision positioning devices, the system cost can be reduced considerably.

Providing a snapshot copy of data includes selectively collecting a plurality of data objects based on evaluation of a predicate associated with each of the data objects and performing a snapshot operation in connection with modifying at least one of the plurality of data objects. The snapshot operation may be performed prior to modifying the at least one of the plurality of data objects. The snapshot operation may be a copy on write operation. Providing a snapshot copy of data may also include providing a data structure that maintains a plurality of snapshot instances. The data structure may be a table. Each of the snapshot instances may include at least one of: an object set description, a timestamp indicating when the snapshot was initiated, a snapshot name and a handling policy.

The invention provides a knowledge management system particularly suited for use in the integrated circuit design environment. The system allows administrators to define standardized component types. Instantiated components versions comprise “deliverables” and “attributes.” Deliverables comprise a file or directory of files or groups of files or directories that perform a common function and are characterized by the system in a standardized manner. Attributes comprise metadata describe the component version. By the abstraction of design files into deliverables, the systems can work with design files originating from any source and having different structures and still make those design files available by other designers in a uniform manner for efficient reuse of pre-qualified components. Tasks in the design flow can be tracked in the system. The system may also include a communications application, an issue tracking application, and an audit trail application.
