20090069895 | Prosthetic Intervertebral Discs Having Folding End Plates That Are Implantable By Minimally Invasive Surgical Techniques - The described devices are spinal implants that may be surgically implanted into the spine to replace damaged or diseased discs using a posterior approach. The discs are prosthetic devices that approach or mimic the physiological motion and reaction of the natural disc. | 03-12-2009 |
20100114318 | Prosthetic Intervertebral Discs - Prosthetic intervertebral discs, systems including such prosthetic intervertebral discs, and methods for using the same are described. The subject prosthetic discs include upper and lower endplates separated by a compressible core member. The subject prosthetic discs exhibit stiffness in the vertical direction, torsional stiffness, bending stiffness in the sagittal plane, and bending stiffness in the front plane, where the degree of these features can be controlled independently by adjusting the components, construction, and other features of the discs. | 05-06-2010 |

20090327519 | ADDING INDIVIDUAL DATABASE FAILOVER/SWITCHOVER TO AN EXISTING STORAGE COMPONENT WITH LIMITED IMPACT - High availability architecture that employs a mid-tier proxy server to route client communications to active data store instances in response to failover and switchover. The proxy server includes an active manager client that interfaces to an active manager in each of the backend servers. State information and configuration information are maintained separately and according to semantics consistent with needs of corresponding data, the configuration information changing less frequently and more available, the state information changing more frequently and less available. The active manager indicates to the proxy server which of the data storage instances is the currently the active instance. In the event that the currently active instance is inactive, the proxy server selects a different backend server that currently hosts the active data store instance. Client communications are then routed to the different backend server with minimal or no interruption to the client. | 12-31-2009 |

20120101997 | DATABASE DATA RECOVERY SYSTEM AND METHOD - The present invention relates to a system and method of data restoration, for instance, after the occurrence of a user error. In particular, snapshot database can be maintained that stores a copy of database data. The snapshot database does not have to store a complete copy of all data on a source database, but rather shares data that is common to both but not necessarily identical. If an error occurs on the primary database then the database can be reverted back to a point in time prior to the error by replacing source database files with snapshot files. Additionally, an undo component can be employed in conjunction with the snapshot to approach an error to a finer grained point in time. In brief, the present invention can restore a database much faster and simpler, while utilizing less space and resources than conventional data restoration technologies. | 04-26-2012 |

20090319583 | INTEGRATED DATA AVAILABILITY AND HISTORICAL DATA PROTECTION - A single native integrated system may be provided for replicating data to one or more copies of high-availability data and for replicating the data to one or more copies of backup data. The data may be replicated, in near real-time, to the one or more copies of high-availability data as changes occur to the data. The data may be replicated and later incorporated to a copy of the backup data at different points in time. The single native integrated system may have a single set of functions for replicating the data to the one or more copies of high-availability data and for replicating the data for the one or more copies of the backup data. Administrative access to the one or more copies of high-availability data may be isolated from administrative access to the one or more copies of the backup data. | 12-24-2009 |
