Multi-row database data loading for enterprise workflow application
Embodiments of the invention are directed to a system, method, or computer program product for providing expedited loading/inserting of data by an entity. Specifically, the invention expedites the loading/inserting of large quantities of data to database tables. Initially received data for loading is processed, via multi-row insert, onto in-memory or temporary tables. The data is staged on a temporary table while the appropriate base table is determined. Once determined, data from the temporary table is pointed to the base table. In this way, a massive amount of data loading from the temporary table to a base table may occur. This prevents logging and locking associated with adding individual data points or row to a base table independently. Errors are check and processed accordingly. Once updated, the data on the temporary table is deleted in mass and a check point restart is issued. |

Method and system for improved communication security
Security is improved in a communication system in which a communication connection is established when a user who has received a software button on his computing device (a Recipient) clicks on the button. When a Recipient first actuates a software button, a basic type of communication connection is established, during which the Recipient's identity can be verified. The Recipient then establishes a personal identification code, which he will have to provide upon future actuations of the software button. The system then enables other types of communication connections to be established by the Recipient. After the Recipient actuates the software button and verifies his identity, the system remembers the identity and location of the computing device he is using. When the Recipient subsequently actuates the software button, the identity and location of his computing device are checked, and verification of his identity is suppressed if they have not changed. |

Custom routing decisions
With the advent of virtualization technologies, networks and routing for those networks can now be simulated using commodity hardware rather than actual routers. For example, virtualization technologies such as those provided by VMWare, XEN, or User-Mode Linux can be adapted to allow a single physical computing machine to be shared among multiple virtual networks by providing each virtual network user with one or more virtual machines hosted by the single physical computing machine, with each such virtual machine being a software simulation acting as a distinct logical computing system that provides users with the illusion that they are the sole operators and administrators of a given hardware computing resource. In addition, routing can be accomplished through software, providing additional routing flexibility to the virtual network in comparison with traditional routing. As a result, in some implementations, supplemental information other than packet information can be used to determine network routing. |

Methods and apparatuses for performing protection switching without using Y.1731-based automatic protection switching (APS) messages
To perform protection switching between tunnels in a network, Y.1731-based APS messages are often sent from a management system to nodes at the tunnels' end-points. If the management system is located near one node (local node) and far away from the other node (remote node), the APS message, which operates at the Ethernet service layer, travels to the remote node slower than traffic over the tunnels. This slower transmission time may prevent the remote node from performing a switch within a desired timeframe. The disclosed embodiments include a 1:1 bidirectional VLAN-based protection arrangement that accomplishes a 50 millisecond switching time without using Y.1731-based APS messages. The embodiments accomplish this by sending a switching command from the management system to the local node and modifying a message already traveling from the local node to the remote node to include a switching message that causes the remote node to perform the switch. |

The polarization extinction ratio may be defined as: 10 log(PEx/PEy), where PEx is the power of the optical signal propagating along the “x axis” and PEy is the power propagating along the orthogonal “y axis” (with the z-axis defined as a longitudinal optical axis of the system and the x-y plane orthogonal to this direction of propagation). The PER monitor comprises a section of optical fiber (preferably birefringent or with induced birefringency), with a pair of gratings formed along the fiber and oriented to out-couple orthogonal components of the propagating signal. Photodetectors are used to convert the scattered light into electrical signal equivalents and then processed to yield the PER value. By properly aligning the axes of the monitor and the optical system, the two measurements are sufficient to provide a one-shot, real-time calculation of the PER of the optical signal propagating through the system. |

Liquid crystal display device
Occurrence of an event can be prevented, whereby, when a backlight expands with heat, a light guide plate might move a group of optical sheets into contact with a middle frame and deform the sheets, thereby causing nonuniformity of luminance on a screen. In particular, a protrusion is formed at an edge of the plate, and the sheets are mounted on the plate to avoid the protrusion. The frame covers the protrusion and the edge of the sheets. Even if a spatial gap with respect to the frame is lost by expansion of the plate, the sheets suffer no deformation due to interference between an edge of the sheets and the frame. Therefore, the nonuniformity of luminance on the screen does not occur, either. Also, unusual sounds due to movement of the plate under vibration do not arise since a gap between the protrusion and the frame can be small. |
