20140238859 | NUCLEIC ACID SEQUENCING BY ELECTROCHEMICAL DETECTION - Provided herein is technology relating to sequencing nucleic acids and particularly, but not exclusively, to devices, methods, and systems for sequencing-by-synthesis using changes in pH to monitor base addition. In some embodiments the electrochemical hydrogen ion sensor is a microfabricated mixed metal oxide electrode and in some embodiments the electrochemical hydrogen ion sensor is a membrane electrode. Moreover, in some embodiments the device further comprises a reference electrode. Performing the sequencing reaction involves moving solutions and other fluids (e.g., samples, nucleotide solutions, wash solutions) into and out of the reaction vessel. Thus, in some embodiments, the device further comprises a tube or other transport mechanism or pathway attached to the reaction vessel. | 08-28-2014 |

20130094436 | LTE SUBSCRIBER IDENTITY CORRELATION SERVICE - Various exemplary embodiments relate to a method performed by a network node for correlating subscriber IDs in a communication network, the method including: receiving a message from another network node that relates to an application function containing information related to a subscriber of the application function; extracting subscriber identification information for the message; determining if the extracted subscriber identification information is found in a correlation object in a correlation object database; if the extracted subscriber identification information is found, then adding the extracted subscriber identification information to the correlation object found in the correlation object database. | 04-18-2013 |
20130094521 | NAI SUBSCRIPTION-ID HINT DIGIT HANDLING - Various exemplary embodiments relate to a method of identifying a subscriber at a network node. The method may include: receiving a message including a network access identifier (NAI); removing the first digit from the NAI to form a stripped NAI; determining whether the stripped NAI corresponds to a subscriber; determining whether the NAI corresponds to a subscriber; adding a hint digit to form an extended NAI, and determining whether the extended NAI corresponds to a subscriber; and if any of the NAIs correspond to a subscriber, using the corresponding NAI to identify the subscriber. Various exemplary embodiments relate to a policy and charging rules node including: a subscriber cache including a subscriber identifier; an interface configured to receive a NAI; a NAI modifier configured to form an extended NAI and a stripped NAI; and a subscriber identification module configured to determine whether a NAI is stored in the subscriber cache. | 04-18-2013 |

20150326559 | METHOD AND SYSTEM FOR AUTHORIZING SECURE ELECTRONIC TRANSACTIONS USING A SECURITY DEVICE - Methods and systems for authenticating a security device for providing a secure access and transaction authorization to a remote network location are provided. The security device is authenticated by installing private security software on the security device. A Two-Channel authorization method includes a transaction notification/authorization channel and a transaction channel. A Three-Channel authorization method includes a transaction notification channel, a transaction authorization channel, and the transaction channel. Embodiments of the present invention provide increased security and privacy. A corresponding system for authenticating a security device and preforming secure private transactions is also provided. | 11-12-2015 |
20150326565 | METHOD AND SYSTEM FOR AUTHORIZING SECURE ELECTRONIC TRANSACTIONS USING A SECURITY DEVICE HAVING A QUICK RESPONSE CODE SCANNER - Methods and systems for authenticating a security device for providing a secure access and transaction authorization to a remote network location are provided. The security device is authenticated by installing private security software on the security device. In order to authorize a transaction, a transaction authorization is performed using the security device by display a QR (Quick Response) code from an authorization server on a user terminal and scanning the QR code into the security device. After scanning the QR code, an OTA (One-Time-Authorization) code is sent from the security device to the authorization server for verifying the transaction. Embodiments of the present invention provide increased security and privacy. A corresponding system for authenticating a security device and preforming secure and private transactions is also provided. | 11-12-2015 |

20130294450 | OPTIMIZED TRIE-BASED ADDRESS LOOKUP - One embodiment of the present invention provides a router. The router includes a storage, a forwarding table management mechanism, and a longest prefix matching mechanism. The storage stores, in a data structure corresponding to a rich prefix node associated with a trie, a plurality of network address prefixes represented by the trie. The forwarding table management mechanism expresses a respective network address prefix using one or more of: 1) a traversal path on the trie from a root node to a subtrie of the trie; and 2) an encoded representation of a node in the subtrie. The longest prefix matching mechanism matches a network address with a longest prefix from the network address prefixes stored in the data structure corresponding to the prefix node. | 11-07-2013 |
