20100298932 | IMPLANTABLE ARTIFICIAL VENTRICLE HAVING LOW ENERGY REQUIREMENT - A pulsatile, positive-displacement mechanical circulatory support pump which can be used for assistance or replacement of one or both ventricles. The pump includes a plurality of contractile elements radiating outward from an apex of a compliance chamber, the elements being incorporated in and/or in contact with at least a portion of an outer surface of the compliance chamber. These contractile elements include an electroactive dielectric elastomer or an ion exchange membrane metallic composite. Application of electric field pulses from an implantable electrical energy source such as a pacemaker will cause the contractile elements to compress and expand the compliance chamber. | 11-25-2010 |

20120201148 | Method Of Managing User Traffic To Prevent Aggressive Users From Abusing Network Resources - In one embodiment, a plurality of queues are established corresponding to each of a plurality mobiles, respectively. Data packets associated with the plurality of mobiles are received at a network element. Each received data packet is assigned to a corresponding one of the plurality of queues. A determination operation is performed on a selected one of the plurality of queues to determine whether or not to send one or more packets of each queue from the network gateway element. The determination operation is performed based on a comparison between a packet size of a head packet and an adaptive transmission threshold value associated with the selected queue. The adaptive transmission threshold value is a value that is changed based on an amount data sent from the selected queue. The head data packet being an earliest received data packet in the selected queue. | 08-09-2012 |

20090285099 | METHOD AND APPARATUS FOR PROVIDING CONGESTION CONTROL IN RADIO ACCESS NETWORKS - The invention includes a method and apparatus adapted for controlling congestion in a Radio Access Network (RAN). In one embodiment, a method includes monitoring packets received at a first network element of the RAN for an indication of congestion, where the packets are associated with a quality-of-service class, and, in response to detecting an indication of congestion in at least one of the received packets, signaling congestion status information from the first network element of the RAN toward a second network element of the RAN that is adapted for applying congestion control for the quality-of-service class. In one embodiment, a method includes receiving, at a first network element of the RAN, from a second network element of the RAN, congestion status signaling indicative of a congestion condition associated with a quality-of-service class, and applying congestion control for the quality-of-service class in response to receiving the congestion status signaling indicative of the congestion condition. | 11-19-2009 |
20090296613 | METHOD AND APPARATUS FOR PROVIDING QUALITY-OF-SERVICE IN RADIO ACCESS NETWORKS - The invention includes a method and apparatus adapted for providing quality-of-service to a packet flow within a Radio Access Network (RAN). In one embodiment, a method includes receiving packets of a packet flow at a first network element of the RAN, where the packet flow is associated with an application normally served in a best effort service class of the RAN and each packet of the packet flow comprises an indication of a quality-of-service policy to be applied to the packet flow within the RAN, and, applying the indicated quality-of-service policy to the packet flow within the RAN. The quality-of-service policy to be applied to the packet flow within the RAN is based on at least one characteristic of the packet flow, which may be determined in any manner, such as using information included in the packet headers, using deep packet inspection techniques, and the like. The indication of the quality-of-service policy to be applied to the packet flow within the RAN may be set either inside the RAN or outside the RAN. | 12-03-2009 |

20090147143 | VIDEO QUALITY ANALYSIS USING A LINEAR APPROXIMATION TECHNIQUE - A video analysis technique includes correlating frames from a processed video with frames from a pre-processed, original video. A linear approximation of a relationship between the correlated frames is determined. A disclosed example includes determining a linear approximation that maximizes the number of processed video frames that fit into the linear approximation. The linear approximation and whether any frames do not fit within the linear approximation is then used to provide quality information for analyzing a quality of the processed video. | 06-11-2009 |

20110161101 | SYSTEM AND METHOD FOR CONTINUOUS DATA ANALYSIS OF AN ONGOING CLINICAL TRIAL - System and method of continuously analyzing trial data of an ongoing clinical trial is provided. A statistical analysis is performed on a trial database containing subject trial data without suspending the ongoing clinical trial. If the result of the statistical analysis does not exceed a predetermined threshold value, then the statistical analysis is repeated while the clinical trial is ongoing. In a blinded clinical trial, a grouped database is generated from the trial database and a blinding database prior to performing the statistical analysis. The grouped database groups the subject trial data according to the study groups. The ability to continuously monitor and analyze the trial data for statistical significance in tandem with data collection while the trial is ongoing provides many benefits to the researchers because the trial database no longer becomes the bottleneck in obtaining useful results and statistical analysis can be conducted on a near real-time basis without having to wait until completion of the trial. | 06-30-2011 |
