Network system and peripheral
A network system is made up of a plurality of PCs, a printer a server, and the like. The printer selects one PC from among the plurality of PCs as a firmware provider. Accordingly, if there are two or more PCs that can communicate with the printer, only one PC communicates with the server at the same time. Thus, to retrieve firmware from the server, a plurality of PCs can be prevented from communicating with the server at the same time, so that concentration of access to the server can be suppressed. Therefore, an increase in the network traffic can be suppressed. |

System and method for a combination group and individual travel insurance program
The present invention allows travel organizations to ensure that basic group, or “Core,” travel medical coverage is in effect for their travelers while allowing travelers the ability to upgrade the “Core” insurance if needed or desired. Thus, the organization need not purchase excess insurance, thereby reducing the organization's liability for their group purchase decision. Until now, combining group and individual travel medical insurance has been impossible. Individual travel medical insurance policies could be customized, but travelers covered by a group policy had to accept the coverage their organizations chose. The present invention allows travelers with different needs and tastes from around the world to customize group travel insurance coverage according to their needs and desires. By offering choice, the present invention reduces the likelihood that travelers can successfully claim later that insurance required under the group program was inadequate. |

Apparatus and method for processing service interactions
An interactive voice and data response system that directs input to a voice, text, and web-capable software-based router, which is able to intelligently respond to the input by drawing on a combination of human agents, advanced speech recognition and expert systems, connected to the router via a TCP/IP network.

The router manages the interactions and keeps pace with a real-time conversation. The system utilizes both speech recognition and human intelligence for purposes of interpreting customer utterances or customer text, where the role of the human agent(s) is to input the intent of caller utterances, and where the computer system—not the human agent—determines which response to provide given the customer's stated intent (as interpreted/captured by the human agents). The system may use more than one human agent, or both human agents and speech recognition software, to interpret simultaneously the same component for error-checking and interpretation accuracy. |

Method for accelerating failover of VPN traffic in an MPLS provider network
Failover of VPN traffic between MPLS tunnels may be accelerated by determining a main and a standby MPLS tunnel for each VPN and passing both the main and standby MPLS tunnel information to the forwarding plane of a network element configured to implement the VPN.

Since the standby MPLS tunnel has already been determined, and information associated with the standby MPLS tunnel has already been provided to the forwarding plane, it is not necessary to recompute a new MPLS tunnel or reprogram the forwarding plane using the new MPLS tunnel information. By removing control plane operations and control plane-forwarding plane interaction from the handling of failovers, the failover recovery time may be accelerated to under 50 ms, to thereby enable VPN connections to handle time sensitive traffic. |

Nonvolatile memory devices including a memory cell array with a plurality of memory blocks and a plurality of bit lines arranged at the memory cell array. Each of the plurality of memory blocks may include a plurality of strings arranged in rows and columns and formed to be vertical to a substrate. Strings of each row of each memory block are connected with the bit lines, respectively, and strings of each column of each memory block are connected in common with a corresponding one of the bit lines. One memory block of the plurality of memory blocks includes a first region for storing ROM data and a second region for storing replica ROM data for repairing the ROM data. |

Multiple level cell memory device with single bit per cell, re-mappable memory block
A system having a non-volatile memory device has a plurality of memory cells that are organized into memory blocks. Blocks can operate in either a multiple bit per cell mode or a single bit per cell mode. A processor controls the system and selects blocks to operate in the multiple bit per cell mode and single bit per cell mode. One dedicated memory block is capable of operating only in the single bit per cell mode. If the dedicated memory block is found to be defective, a defect-free block can be remapped to that dedicated memory block location to act only in the single bit per cell mode. |
