| 20080288002 | Spinal Stabilization Systems and Methods - One embodiment provides a bone fastener including a collar, a fastener member, and a pin. The collar can have an upper portion with slot to receive an elongated member and a lower portion with a socket and an opening. The fastener member can have head and shank portions. The socket can receive the head portion and prevent movement of the head portion through the opening when the head portion is out of registration with the opening. The head portion and the socket can be configured to allow angulation of the fastener member within a defined range of motion within a selected plane. The head portion and the socket can define apertures which can be aligned with each other when the head portion is in the socket and which can receive the pin. One embodiment provides a generally spherical head portion with a flat. | 11-20-2008 |
| 20090005787 | DEVICE AND SYSTEM FOR IMPLANTING POLYAXIAL BONE FASTENERS - A device, is provided for implanting in bony tissue a bone fastener rotatably connected to a collar. The sleeve is configured for threaded connection to the collar and has a central bore aligned with the longitudinal axis of the sleeve for receiving an inner shaft. The inner shaft inserts in the sleeve and has a distal end configured for connection to a portion of the bone fastener, such as an internal hex feature. In some embodiments a movable member may be inserted in an opening transverse the central bore and positionable to either rotatably or fixedly connect the inner shaft to the sleeve. In other embodiments, a collet nut threads onto a collet thread to radially compress sleeve tangs to frictionally engage inner shaft to sleeve. | 01-01-2009 |
| 20090005813 | APPARATUS AND METHODS FOR SPINAL IMPLANTS - A polyaxial screw device and system for spinal fixation and dynamic stabilization. Embodiments of the present disclosure may utilize hinged connections, cam-style mechanisms, and planar connectors to enable surgeons to attach to an implanted bone fastener or connect to an elongated member from a lateral approach for improved accessibility, with a low-profile configuration for improved patient comfort. Embodiments may be implantable using MIS procedures and techniques. | 01-01-2009 |

| 20120072972 | SECONDARY CREDENTIALS FOR BATCH SYSTEM - A batch job system may create a second set of credentials for a user and associate the second set of credentials with the user in an authentication server. The second set of credentials may allow computers running the batch jobs to have user-level authentication for execution and reporting of results. The second set of credentials may be a single sign on type of credential, and may consist of a virtual smartcard that each worker computer may use for authentication. In some embodiments, authentication requests may be routed to a virtual or physical Hardware Security Module. | 03-22-2012 |

| 20100116239 | Sliding valve assembly - A sliding valve assembly includes a valve body having a fluid conducting port adjacent to a fluid impervious surface. The actuator allows fluid to travel through the valve assembly and into a fluid blocking position where the fluid impervious surface obstructs the fluid from traveling through the valve assembly. First and second sealing assemblies include a primary seal ring, a secondary seal ring around the primary seal ring, and a spring forcing the primary seal ring against a sealing surface. As pressure in the system increases, this pressure is delivered to the sealing assemblies to force them against the sealing surfaces to enhance the sealing relationship. Cams and cam followers affixed to the valve body overcome the frictional forces of the sealing system and the valve body and valve housing to increase the efficiency of the valve assembly and the system in which the valve assembly is used. | 05-13-2010 |

| 20100028594 | METHOD AND SYSTEM FOR MANUFACTURING A BLADE - A method of manufacturing a blade is provided. The method includes providing a plurality of first plies, each of the first plies sized to extend substantially the length of a span of the blade and providing a plurality of second plies, each of the second plies sized to extend only partially the length of the span of the blade. The method also includes layering the plurality of first plies and the plurality of second plies in a mold such that the plurality of second plies is interspersed throughout the plurality of first plies to spread apart the plurality of first plies to facilitate increasing a cross-sectional area of the blade and bonding the plurality of first plies to the plurality of second plies to facilitate forming a structural core of the blade. | 02-04-2010 |

| 20100329863 | METHOD FOR REDUCING TIP RUB LOADING - A method for reducing tip rub loads in a rotor blade is described having the steps of selecting a location of contact between the rotor blade and a static structure; selecting a location on the blade for incorporating a tip-cutter; selecting a cutter-profile for the tip-cutter; and incorporating the tip-cutter on the selected location on the blade such that tip-cutter is capable of removing a portion of the static structure during a tip rub such that tip rub loads are facilitated to be reduced. | 12-30-2010 |
| 20100329875 | ROTOR BLADE WITH REDUCED RUB LOADING - An airfoil for use in a rotor assembly is disclosed, the airfoil having a tip-cutter located on a sidewall near a tip portion, wherein the tip-cutter is capable of removing a portion of an abradable material during a tip rub. In another embodiment, an airfoil has a tip-grinder located on the tip portion, wherein the tip-grinder capable of removing a portion of an abradable material during a tip rub. In another embodiment, an airfoil has a tip-rake that facilitates reducing loading induced to said airfoil during tip rubs. | 12-30-2010 |
