20100085922 | System and method for improving bandwidth of wireless local area network - A system and method for improving bandwidth of a local area network is provided. The method includes splitting user data into multiple data fragments. The method further includes creating multiple beacon frames by placing each data fragment in a unique beacon frame. Further, the method includes broadcasting the beacon frames through a wireless medium by an access point of the network. Thereafter, the beacon frames are received by a wireless client and data fragments are extracted from each beacon frame. Finally, the user data is reconstructed from the extracted data fragments by reassembling the data fragments. | 04-08-2010 |
20100111054 | System and method for robust data loss recovery in a wireless local area network - A system and method for robust data loss recovery in a wireless local area network is provided. The method includes splitting user data into multiple data fragments. The method further includes creating multiple beacon frames by placing each data fragment in a unique beacon frame and broadcasting the beacon frames through a wireless medium by an access point of the network. Prior to transmission, the method includes arranging the frames into a plurality of groups and creating a parity frame for each group, to be transmitted along with the beacon frame. After transmission, the beacon frames are received by a wireless client and data fragments are extracted from each beacon frame. At the receiving end, the wireless client checks whether all the transmitted beacon frames have been received. Finally, the user data is reconstructed from the extracted data fragments by reassembling the data fragments. | 05-06-2010 |

20100227301 | APPARATUS AND METHODS FOR OPERATOR TRAINING IN INFORMATION EXTRACTION - Disclosed are methods and apparatus for extracting information from one or more documents. A training and execution plan is received, and such plan specifies invocation of a trainer operator for initiating training of a trainee operator based on a set of training documents so as to generate a new trained operator that is to then be invoked so as to extract information from one or more unknown documents. The trainee operator is configured to extract information from one or more unknown documents, and each training document is associated with classified information. After receipt of the training and execution plan, the trainer operator is automatically executed to train the trainee operator based on the specified training documents so as to generate a new trained operator for extracting information from documents. The new trained operator is a new version of the trainee operator. After receipt of the training and execution plan, both the trainee operator are automatically retained for later use in extracting information from one or more unknown documents and the new trained operator for later use in extracting information from one or more unknown documents. After receipt of the training and execution plan, the new trained operator is automatically executed on one or more unknown documents so as to extract information from such one or more unknown documents. | 09-09-2010 |
20110264651 | LARGE SCALE ENTITY-SPECIFIC RESOURCE CLASSIFICATION - A system and method is described for large scale entity-specific classification of each entity-specific set of candidates in a collection of candidates for each specific entity in a collection of entities. The collection of entities may comprise a specific category or domain of entities (e.g. schools, restaurants, manufacturers, products, events, people). Candidates may comprise webpages or other resources with resource identifiers. Entity specific sets of candidates may be found by leveraging search engine query results and user interaction therewith for queries based on entity-specific attributes. The relationship(s) or class(es) for which candidate resources are being classified relative to a specific entity may comprise an authoritative, official home page (OHP), or other class (e.g. fan page, review, aggregator) relative to a specific entity. A feature generator generates entity-specific features for candidates. In accordance with its features, one or more classifiers rank each candidate for a specific class for a specific entity. | 10-27-2011 |
