摘要： A scheme for retrieving digital multimedia content from a network node. An RTSP SET_PARAMETER message is provided to the network node by a client application executing on a digital multimedia device, wherein the message contains at least one of a playlist identifier, a media clip index and an indication of an activation time. Responsive to the message, content from a particular content source identified by the playlist indentifier, the media clip index, or both, is streamed to the digitial multimedia device at a time determined responsive to the activation time.

摘要： A method for facilitating multimedia streaming using server-side playlists comprises a plurality of operations. An operation is performed for streaming current playlist selection data from a server that supports server-side playlists to a client having a jitter buffer. An operation is performed for receiving at the server a request for streaming multimedia content corresponding to a different playlist selection. An operation is performed for communicating client-server specification information between the server and the client for enabling the different playlist selection data to be streamed from the server to the client at a data transfer rate greater than a maximum data presentation rate. The operation for communicating client-server specification information includes transmitting from the server for reception by the client information acknowledging that the server supports faster than real-time streaming and receiving at the server information designating a current size of the jitter buffer and a maximum data rate at which data is receivable by the client. The server performs an operation for streaming the different playlist selection data from the server for reception by the client after the operation for communicating client-server specification information is performed. The different playlist selection data is streamed at a data transfer rate greater than the maximum data transfer rate at which data is outputable from the jitter buffer.

摘要： The normal control of an electrically-activated hydraulic valve armature is overridden to automatically and periodically open the armature for flushing out debris that has accumulated between the armature and a seat that the armature is designed to engage. The valve develops fluid pressure for maintaining engagement of a motor vehicle transmission clutch, and when excessive slippage of the clutch is detected, the armature is forced into engagement with the seat until the slippage is reduced or a predetermined period of time has elapsed, after which the armature is temporarily positioned away from the seat to provide full flow of hydraulic fluid across the seat to flush out debris that prevents the armature from engaging the seat. During Neutral operation of the transmission, the armature is continuously positioned away from the seat, and during low torque conditions the armature is temporarily positioned away from the seat.

摘要： A method and apparatus for efficiently cooling and lubricating rotating components in a hybrid transmission is provided. By efficiently managing cooling flow to and between the rotating elements, flow requirements and associated pumping requirements within the drive unit are minimized. In addition, by providing a method for placing the fluid directly on the required components, spin losses associated with component contact with stray oil are reduced. Combined, the reduction in pumping and spin losses create a more efficient drive unit and an overall more efficient hybrid drive system which directly leads to higher fuel economy.

摘要： A solar array according to this invention includes a solar blanket which is folded into adjacent panels that are hinged together in an accordion-folded mode at parallel hinges. A pair of foldable spines is fixed to the panels and runs the length of the array. The hinges are included in the spine. The spines are mounted at one end to a base plate, and also at the other end to a tip plate. The base plate is intended to be attached to the spacecraft structure with a yoke which will provide required standoff for rotational clearance during sun-tracking. A pantograph deployment structure extends between the two plates. It can be retracted for storage and extended to deploy the blanket. A conductive harness is attached to the blanket to collect current from the panels.
