Alternative methods of constructing a vertically offset structure are disclosed. An embodiment includes forming a flexible layer having first and second end portions, an intermediate portion coupling the first and second portions, and upper and lower surfaces. The distance between the upper and lower surfaces at the intermediate portion is less than the distance between the upper and lower surfaces at the first and second end portions. The first end portion is bonded to a base member. The second end portion of the flexible layer is deflected until the second end portion contacts the base member. The second end portion is bonded to the base member.

Anchor systems and methods anchor components of a Micro-Electro-Mechanical Systems (MEMS) device to a substrate. An exemplary embodiment has a trace anchor bonded to a substrate, a device anchor bonded to the substrate, and an anchor flexure configured flexibly couple the trace anchor and the device anchor to substantially prevent transmission of a stress induced in the trace anchor from being transmitted to the device anchor.

System and methods offset mechanism elements during fabrication of Micro-Electro-Mechanical Systems (MEMS) devices. An exemplary embodiment applies a voltage across an offset mechanism element and a bonding layer of a MEMS device to generate an electrostatic charge between the offset mechanism element and the bonding layer, wherein the electrostatic charge draws the offset mechanism element to the bonding layer. The offset mechanism element and the bonding layer are then bonded.

The present invention generally relates to a method and an apparatus for selectively isolating a portion of a wellbore. In one aspect, an apparatus for isolating a zone in a wellbore is provided. The apparatus includes a body having a bore. The apparatus further includes a first flapper member and a second flapper member, each flapper member selectively rotatable between an open position and a closed position. Additionally, the apparatus includes a flapper latch assembly disposed in the bore, the flapper latch assembly movable between an unlocked position and a locked position, wherein the flapper latch assembly is configured to hold the first flapper member in the closed position when the flapper latch assembly is in the locked position. In another aspect, a method for selectively isolating a zone in a wellbore is provided. In yet a further aspect, a flapper latch assembly for use with a flapper valve is provided.

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.

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.

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.

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.
