20090067572 | Measurement of Lead by X-Ray Fluorescence - A method, instrument, and computer program software product for characterizing a sample with respect to the presence of a specified element, either as a constituent of a surface layer or of the bulk of the sample. Intensities of fluorescent emission at two characteristic emission lines are compared to establish whether the specified element is disposed above the bulk of the sample. In the case where the specified element is disposed above the bulk of the sample, an areal density of the specified element is determined, whereas in the case where the specified element is disposed within the bulk of the sample, a volumetric concentration of the specified element within the sample is determined. | 03-12-2009 |

20150262402 | OBJECT CUSTOMIZATION AND ACCESSORIZATION IN VIDEO CONTENT - A real-time video exploration (RVE) system that allows users to pause, step into, move through, and explore 2D or 3D modeled worlds of scenes in a video. The RVE system may allow users to select and manipulate objects within a scene, and to modify an object by adding or removing accessories from the object or otherwise customizing the object according to the user's preferences or desires. The RVE system may also provide an interface or interfaces via which the user can obtain additional information for the object, customize the object, be given a price or price(s) for the object as customized, and purchase the object as specified if desired. | 09-17-2015 |
20150262423 | REAL-TIME EXPLORATION OF VIDEO CONTENT - A real-time video exploration (RVE) system that allows users to pause, step into, and explore 2D or 3D modeled worlds of scenes in a video. The system may leverage network-based computation resources to render and stream new video content from the models to clients with low latency. A user may pause a video, step into a scene, and interactively change viewing positions and angles in the model to move through or explore the scene. The user may resume playback of the recorded video when done exploring the scene. Thus, rather than just viewing a pre-rendered scene in a movie from a pre-determined perspective, a user may step into and explore the scene from different angles, and may wander around the scene at will within the scope of the model to discover parts of the scene that are not visible in the original video. | 09-17-2015 |
20150264416 | REAL-TIME RENDERING OF TARGETED VIDEO CONTENT - A real-time video targeting (RVT) system may leverage network-based computation resources and services, available 2D or 3D model data, and available viewer information to dynamically personalize content of, or add personalized content to, video for particular viewers or viewer groups. When playing back pre-recorded video to viewers, at least some objects or other content in at least some of the scenes of the video may be replaced with objects or content targeted at particular viewers or groups according to profiles or preferences of the viewers or groups. Since the video is being rendered and streamed to different viewers or groups in real-time by the network-based computation resources and services, any given scene of a video may be modified and viewed in many different ways by different viewers or groups based on the particular viewers' or groups' profiles. | 09-17-2015 |
20150264425 | OBJECT DISCOVERY AND EXPLORATION IN VIDEO CONTENT - A real-time video exploration (RVE) system that allows users to pause, step into, move through, and explore 2D or 3D modeled worlds of scenes in a video. The RVE system may allow users to discover, select, explore, and manipulate objects within the modeled worlds used to generate video content. The RVE system may implement methods that allow users to view and explore in more detail the features, components, and/or accessories of selected objects that are being manipulated and explored. The RVE system may also implement methods that allow users to interact with interfaces of selected objects or interfaces of components of selected objects. | 09-17-2015 |
20150264441 | GENERATING NEW VIDEO CONTENT FROM PRE-RECORDED VIDEO - A real-time video exploration (RVE) system that allows users to pause a pre-recorded video (e.g., a movie) and change viewing positions and angles of one or more scenes. The RVE system may also allow users to select, manipulate, and modify objects within one or more scenes. The RVE system may render new video of the scenes and stream the new video to the user's client device. Using the RVE system, a user may create modified versions of one or more scenes to replace original scenes in a video to thus create a modified version of the video. The RVE system may allow the user to record the modified version of the video, and may allow the user to share the modified version of the video with other viewers. | 09-17-2015 |
