20130161237 | HYDROPROCESSING OF HEAVY HYDROCARBON FEEDS - Heavy oil feeds are hydroprocessed in the presence of a solvent under conditions that provide a variety of benefits. The solvent can be an added solvent or a portion of the liquid effluent from hydroprocessing. The processes allow for lower pressure processing of heavy oil feeds for extended processing times or extended catalyst lifetimes be reducing or mitigating the amount of coke formation on the hydroprocessing catalyst. | 06-27-2013 |
20140296057 | MITIGATION OF PLUGGING IN HYDROPROCESSING REACTORS - The behavior of a monitored condition over time for a reactor or reaction system can be analyzed using groupings or windows of data to identify anomalous features in the time-average values. Anomalous features can be identified based on a threshold value generated from the analysis. Based on identification of an anomalous feature, a corrective action can be taken. For example, when the monitored condition is the pressure drop across a catalyst bed, detection of an anomaly can indicate the time to initiate a wash process for the catalyst bed before a large drop in catalyst activity occurs. By detecting an anomaly at an earlier point in time, a wash cycle can be initiated earlier so that the wash is more effective at restoring the catalyst bed to a desired condition. | 10-02-2014 |

20130054816 | Determining Validity of SIP Messages Without Parsing - Methods and apparatus are provided for determining the validity of SIP messages, such as self-similar messages, without parsing the message. A SIP message is processed by creating a feature vector matrix of the SIP message; processing the feature vector matrix using a plurality of classifiers; combining results generated by the plurality of classifiers to obtain a combined result; and processing the SIP message based on the combined result. The plurality of classifiers can be trained on a training data set. The SIP message can optionally be classified, for example, as a normal message or an anomalous message based on the combined result. In addition, the SIP message can optionally be processed or rejected based on the combined result. The results generated by the plurality of classifiers are combined using a combination function, such as a voting rule or a logistic regression. | 02-28-2013 |
20150119086 | SIMULTANEOUS LOCALIZATION AND MAPPING SYSTEMS AND METHODS - A system and method for providing localization and mapping within an environment includes at least one mobile device adapted to be moved within the environment. The at least one mobile device includes an inertial measurement unit and at least one radio frequency receiver. The at least one mobile device detects inertial measurements through the inertial measurement unit and values of signal strength through the at least one radio frequency receiver. The system and method also includes a localization module that provides simultaneous localization and mapping of the at least one mobile device within the environment based at least on the inertial measurements detected by the inertial measurement unit and the values of signal strength detected by the at least one radio frequency receiver. | 04-30-2015 |
20150235379 | SYSTEM AND METHOD FOR PROCESSING VISUAL INFORMATION FOR EVENT DETECTION - A system and method processes visual information including at least one object in motion. The visual information is processed by locating at least one spatial edge of the object, generating a plurality of spatio-temporal gradients for the at least one spatial edge over N frames, and then generating motion blur images from the spatio-temporal gradients. A regression analysis is performed on the motion blur images to determine direction of motion information of the object, and scene activity vectors are then generated for the N frames based on the direction of motion information. An event is detected in the visual information based on the scene activity vectors. | 08-20-2015 |

In one embodiment the method includes: (1) monitoring calls to and from a user, (2) obtaining information based on the calls and (3) categorizing a caller associated with at least one of the calls into a contact group according to the information and (4) assigning a genre of tones to the contact group. | 11-06-2008 |
20090214204 | Optical network monitoring using amplifier modeling - Example embodiments include a method for monitoring an optical network. The method provides received network data to a network model, which determines if there is an inconsistency within the optical network. The network models include a statistical model and a detailed-physical model, both of which model amplifier physics. | 08-27-2009 |
20100203901 | Location-Based Services Using Geofences Generated from Learned Patterns of Movement - Location-based services are provided in a communication system comprising a wireless network. In one aspect, information indicative of location of a given mobile user device of the system is periodically collected. The collected location information is processed in a server or other processing device of the system to determine at least one normal pattern of movement of the mobile user device from at least a first location to a second location. An alert is generated if subsequent movement of the mobile user device from the first location to the second location exhibits a significant deviation from the normal pattern of movement. The normal pattern of movement may be used to generate a multidimensional geofence that includes, in addition to a geographic area dimension, at least one additional dimension such as, for example, a speed of movement dimension, a direction of movement dimension, a stop duration dimension, or a related device proximity dimension. | 08-12-2010 |
