20120016420 | DEVICES, SYSTEMS, AND METHODS FOR INTER-TRANSVERSE PROCESS DYNAMIC STABILIZATION - Systems and methods are positioned between left and right transverse processes of adjacent vertebrae in a spine to provide dynamic inter-transverse process distraction and stabilization and indirect expansion of both anterior and posterior spaces of the spine. The systems and methods employ a left support component sized and configured to be mounted between the left transverse processes of the adjacent vertebrae and a right support component and configured to be mounted between the right transverse processes of the adjacent vertebrae. The left and right support components exert a dynamic separation force between the left and right transverse processes generally longitudinally along the spine to distract and stabilize space between the adjacent inferior and superior vertebrae and indirectly expand both anterior and posterior spaces of the spine. The systems and methods relieve pain associated with, e.g. disc herniation, disc degeneration, facet arthropathy, and spinal stenosis. | 01-19-2012 |

20100088788 | STRESS MICRO MECHANICAL TEST CELL, DEVICE, SYSTEM AND METHODS - The invention provides a stress micro mechanical system for measuring stress and strain in micro- and nano-fibers tubes, and wires as well as for measuring the interface adhesion force and stress in nanofibers and nanotubes embedded in a polymer matrix. A preferred system of the invention has a substrate for supporting a MEMS fabrication. The MEMS fabrication includes freestanding sample attachment points that are movable in a translation direction relative to one another when the substrate is moved and a sample is attached between the sample attachment points. An optical microscope images surfaces of the MEMS fabrication. Software conducts digital image correlation on obtained images to determine the movement of the surfaces at a resolution much greater than the hardware resolution of the optical microscope. A preferred method for measuring stress and strain in micro- and nano-fibers, tubes, and wires, and/or measuring the force required to pull-out individual micro- and nano-fibers, tubes, and wires from a polymer matrix and to therefore measure interfacial adhesion is also provided. In the method a sample is attached between freestanding platforms in a MEMS device. Relative translational movement between the platforms is created and motion of the platforms is imaged with an optical microscope. Mechanical and adhesion properties of the sample are determined by applying a digital image correlation algorithm to the image data. | 04-08-2010 |

20120163389 | TECHNIQUES FOR SELECTING PATHS AND/OR TRUNK PORTS FOR FORWARDING TRAFFIC FLOWS - Techniques that offer enhanced diversity in the selection of paths (e.g., ECMP paths) and/or ports from ports associated with trunks for forwarding data traffic. In one embodiment, one or more functions are used to generate a result. A first portion of the generated result may be used as an index (e.g., ECMP index) for selecting a path (e.g., an ECMP path) from multiple possible paths for forwarding a packet. A second portion of the generated result, different from the first portion, may be used as an index (trunk index) for selecting an output port from multiple output ports associated with a trunk for forwarding a packet. In this manner, selected portions of the generated result may be used as indices, one for selecting a path and another for selecting a trunk port for forwarding packets such that the two indices are not the same and are not dependent upon one another. | 06-28-2012 |
