    摘要: A method for video playback switching in response to changing network conditions. The method includes accessing a server to retrieve respective index files for a low bit rate version and a high bit rate version of the video file, and instantiating a low bit rate media player and a high bit rate media. Playback of the video file is begun by the high bit rate media player streaming the high bit rate version from the server. Upon an indication of impeded network conditions, a transition point is selected, wherein the transition point indicates where downloading of the high bit rate version stops and where downloading of the low bit rate version begins. The low bit rate media player is then positioned to begin playback at the transition point. Playback of the video file is then switched to the low bit rate player upon encountering the transition point.

    摘要: A method of controlling the operation of a particulate filter in an exhaust gas after-treatment system may comprise calculating a ratio of particulate loading rate to filter regeneration rate using a mass-based soot load estimation scheme and comparing the ratio of particulate loading rate to filter regeneration rate to a predetermined threshold value. The method may further comprise controlling operating conditions of the particulate filter to maintain the ratio of particulate loading rate to filter regeneration rate at a value above the predetermined threshold value.

    摘要: Described is a technology in which one application running in a browser can host another application (e.g., an advertisement) in an isolated manner that prevents the hosted application from accessing browser data, or data of any other hosted application (including the host). The host and/or hosted application may be a browser plug-in (e.g., Microsoft® Silverlight™) application. The host application privately instantiates a hidden plug-in, with that hidden plug-in's access to browser data disabled, and loads the hosted application in the hidden plug-in. A XAML tag element may be used to identify the hosted application, along with a rendering area for the hosted application. Content from the hosted application is composited with content from the host application when rendering. The host application may provide keywords to the hosted application, such as for selecting relevant advertisements, and/or may allow the hosted application to open a browser window to display associated website content.
