20090000793 | Methods and apparatus for well construction - A method of constructing a well comprising a borehole drilled through underground formations, comprises: positioning at least one device on the outside of the tubular string (e.g. a drill string or casing string), the device being operable to move between first and second configurations; positioning a tubular string in the borehole with the device positioned in the annular space between the tubular string and the borehole wall in its first configuration so as to interact with the tubular string and the borehole while allowing borehole fluid to flow along the annular space and around the device; and operating the device so as to move it from its first configuration to expand into its second configuration in which it substantially fills at least part of the annular space so as to inhibit flow of fluids along the borehole in the space. Apparatus comprises: a string of tubular members; at least one device positioned on the outside of the string, the device being operable to expand between: (i) a first configuration in which, when the tubular string is positioned in the borehole with the device located in the annular space between the tubular string and the borehole wall, interacts with the tubular string and the borehole while allowing borehole fluid to flow along the annular space and around the device; and (ii) a second configuration in which it substantially fills at least part of the annular space so as to prevent flow of fluids along the borehole in the space. | 01-01-2009 |

20120180115 | METHOD AND SYSTEM FOR VERIFYING A USER FOR AN ONLINE SERVICE - A system and method for verifying a user of an online or web service. According to an embodiment, a web page is provided to user for capturing an image of the user together with an embedded verification code. The captured image is provided to a verifier agent and the embedded verification code is compared to an original verification code associated with the user. If there is a match, the user is verified and an account can be created for the user. If there is no match, then the user can be rejected or the verification can be escalated to review by a supervisory agent. According to an embodiment, the embedded verification code comprises a visual representation of the code on a substrate that has been mechanically manipulated. | 07-12-2012 |

20110010765 | FORENSIC TOOLKIT AND METHOD FOR ACCESSING DATA STORED ON ELECTRONIC SMART CARDS - A tool kit for accessing data stored on an electronic SMART card is provided, the kit comprising a SMART card reader and recorder, at least one storage card, and a control card. The card reader and recorder is operative to read and copy the electronic SMART card onto the storage card, and to read the control card, the storage card comprising a storage card security key. The control card comprises code generation means operative to generate a control card security key, copying of the electronic SMART card onto the storage card being prevented unless the control card security key is verified against the storage card security key. | 01-13-2011 |

20140280700 | MULTI-RING RELIABLE MESSAGING SYSTEM - A multi-ring reliable messaging system is formed by interconnecting a plurality of token rings via a pair of gateways that includes an active gateway that is configured to communicate with the token rings and a standby gateway that also is configured to communicate with the token rings. The active gateway receives an original message via a first token ring, generates an associated message for a second token ring based on the original message, and propagates the associated message toward the second token ring. The active gateway supports total order delivery of messages within the token rings and causal-order delivery of messages between the token rings. The standby gateway monitors for original and associated messages received via the token rings in a manner for preventing loss of messages when the active gateway fails. | 09-18-2014 |

20140280821 | Method And Apparatus For Providing Tenant Redundancy - Various embodiments provide a method and apparatus for providing a tenant redundancy architecture that does not require reserving a complete set of duplicate resources, pushing complexity into the application domain or require the application to communicate simultaneously with two active tenant instances. In particular, a shadow tenant is created that has the functionality of the service tenant but is hidden from the rest of the network until activated. | 09-18-2014 |
20140280866 | SCALABLE LOAD BALANCING - Various exemplary embodiments relate to a method and related network node including one or more of the following: receiving, by a load balancer, a plurality of metric values from a plurality of servers; calculating an average metric value based on the plurality of metric values; calculating a first error value based on the average metric value and a first metric value of the plurality of metric values; generating a first integral value by incorporating the first error value into a first previous integral value; and generating a first preference value for a first server of the plurality of servers based on the first integral value. | 09-18-2014 |
