| 20080313031 | CLASSIFICATION OF IMAGES AS ADVERTISEMENT IMAGES OR NON-ADVERTISEMENT IMAGES - An advertisement image classification system trains a binary classifier to classify images as advertisement images or non-advertisement images and then uses the binary classifier to classify images of web pages as advertisement images or non-advertisement images. During a training phase, the classification system generates training data of feature vectors representing the images and labels indicating whether an image is an advertisement image or a non-advertisement image. The classification system trains a binary classifier to classify images using training data. During a classification phase, the classification system inputs a web page with an image and generates a feature vector for the image. The classification system then applies the trained binary classifier to the feature vector to generate a score indicating whether the image is an advertisement image or a non-advertisement image. | 12-18-2008 |

| 20090316795 | Displaying Video at Multiple Resolution Levels - A method of displaying video includes receiving a video bitstream corresponding to a video. The video comprises a sequence of frames having an associated video resolution level. At least a portion of the video bitstream is decoded. A background region of the video is displayed at a first video resolution level and a window region of the video is displayed at a second video resolution level. The second video resolution level is higher than the first video resolution level. | 12-24-2009 |
| 20090320081 | Providing and Displaying Video at Multiple Resolution and Quality Levels - A method provides video from a video data source comprising a sequence of multi-level frames. Each multi-level frame comprises multiple copies of a respective frame. Each copy has an associated video resolution or quality level that is a member of a predefined range of levels that range from a highest level to a lowest level. First video data corresponding to a first portion of a first copy of a respective frame and second video data corresponding to a second portion of a second copy of the respective frame are extracted from the video data source. The video resolution or quality level of the second copy is distinct from that of the first copy. The first and second video data are transmitted to a client device for display. The extracting and transmitting are repeated with respect to successive multi-level frames of the video data source. | 12-24-2009 |

| 20110040241 | BLOOD ACCESS ASSEMBLY FOR ARTIFICIAL LUNG AND RIGHT VENTRICULAR ASSIST DEVICE - A system for providing access to at least one heart chamber for delivering and/or removing a fluid includes a selectively occludable conduit defining a lumen for providing access to an interior of at least one heart chamber from an exterior of a chest wall of the patient, and a dual lumen cannula adapted for passing through an interior lumen of the conduit. The selectively occludable conduit includes at least one balloon closure for substantially sealing an end of the conduit in fluid communication with the chamber of the heart. The dual lumen cannula includes a first, drainage lumen having at least one aperture for removing a fluid from the interior of the heart chamber, and a second, delivery lumen for delivering a fluid into the interior of the heart chamber. The delivery lumen may include an extendable infusion sleeve for delivering a fluid into an interior of the heart. | 02-17-2011 |
