A minimal access tool includes a frame arranged to be attached to an arm of a user, a tool shaft having a proximal end and a distal end, where the tool shaft proximal end is connected to the frame. The tool further includes an input joint having a first end connected to the frame and a second end arranged to receive user input, the input joint including a virtual center-of-rotation (VC) mechanism which provides a center of rotation that generally coincides with a wrist joint of the user. An output joint is connected to the tool shaft distal end, where the output joint is coupled to the input joint via a mechanical transmission connected therebetween to correlate motion of the input joint to motion of the output joint.

A method for reducing the power consumption of a register file of a microprocessor supporting simultaneous multithreading (SMT) is disclosed. Mapping logic and associated table entries monitor a total number of processing threads currently executing in the processor and signal control logic to disable specific register file entries not required for currently executing or pending instruction threads or register file entries not meeting a minimum access threshold using a least recently used algorithm (LRU). The register file utilization is controlled such that a register file address range selected for deactivation is not assigned for pending or future instruction threads. One or more power saving techniques are then applied to disabled register files to reduce overall power dissipation in the system.

A minimal incision maximal access system allows for maximum desirable exposure along with maximum access to the operative field utilizing a minimum incision as small as the METRx and Endius systems. Instead of multiple insertions of dilating tubes the design is is a streamlined single entry device to avoid repetitive skin surface entry. The system offers the capability to expand to optimum exposure size for the surgery utilizing hinged bi-hemispherical or oval working tubes applied over an introducer obturator which is controllably dilated to slowly separate muscle tissue. Deeper end working and visualization areas with maximum proximal access and work dimensions are provided to makes the operative procedure safer in application and shorten the surgeons's learning curve because it most closely approximates the ability to use open microdiskectomy techniques.

Method and apparatus for ensuring secure access to a computer system (1000). The method can begin with the step of receiving in the computer system a request from an entity (using 1002). The entity can have a predetermined access authorization level for access to a first base node (110) representing an information type (102) or a computer system function (104). The system determines if the access request completes a prohibited temporal access pattern for the entity. The system also compares a minimum access level established for the first base node to the predetermined access authorization level assigned to the entity. Thereafter, the system can grant the access request only if the minimum access level for the first base node does not exceed to the predetermined access authorization level.

A bone plate for securing a spinal fixation element to bone includes a base portion having a top face, a rod receiving portion and a bone anchor receiving portion. The bone anchor receiving portion includes a plurality of angled holes for receiving bone screws. At least one of the screw holes is oriented at an acute angle relative to the top face of the plate.

Deeper end working and visualization areas with maximum proximal access and work dimensions are provided to makes the operative procedure safer in application and shorten the surgeons's learning curve because it most closely approximates the ability to use open microdiskectomy techniques. a dual frame system enables full or partial spreading of a working tube set, while an open frame facilitates a four point retraction system.

A tapered sleeve is provided that includes a lubricating coating on an inner surface. An implant (e.g., a pre-filled silicon breast implant) is introduced into a large end of the sleeve and extruded into a surgical pocket of minimal access incision size through a small-sized end of the apparatus.
