Systems and methods of storing previously transmitted data and using it to reduce bandwidth usage and accelerate future communications are described. By using algorithms to identify long compression history matches, a network device may improve compression efficiently and speed. A network device may also use application specific parsing to improve the length and number of compression history matches. Further, by sharing compression histories, compression history indexes and caches across multiple devices, devices can utilize data previously transmitted to other devices to compress network traffic. Any combination of the systems and methods may be used to efficiently find long matches to stored data, synchronize the storage of previously sent data, and share previously sent data among one or more other devices.

Systems, methods and apparatus for delivering content to an audience member over a computer network. A console allows a user to define audience segments that are organized in hierarchical fashion. The segments are then calculated by collecting profile data for audience members and determining whether members have attributes that a defined by the audience segments. The hierarchical definition of segments allows audience segments to be logically combined and facilitates efficient recalculation of audience segments. Profile synchronization provides an authoritative identifier that is used to reconcile the potential issuance of multiple identifiers for a given audience member.

In a synchronization system, the present invention provides an improved user interface through which a user can view and manage settings associated with the user's account in the synchronization system. In the preferred embodiment, a column is displayed for each electronic device associated with the user's account in the synchronization system. In each column is a visual representation of items (e.g., folders) that are (1) backed up, remotely accessible and/or synchronized in the synchronization system and (2) located on the electronic device associated with such column. For each item that is synchronized across multiple devices, all the visual representations of such item in the columns are aligned across a single row in the interface. In the preferred embodiment, there is an arrow, or other visual indicator, between the visual representations of such items to indicate that the items are synchronized.

A distributed computing system, having a sufficient number of devices and requiring a sufficiently large number of devices to select any proposal, can maintain synchronization between its constituent devices and respond to client requests with as few as two message delays. A leader can synchronize the devices of the system and establish a safe proposal number for all current and future steps of the system. Devices can then receive client requests directly, treating the request as a proposal having the proposal number determined previously by the leader, and voting for the proposal. If the client receives an indication from a least a quorum of devices, where a quorum can be the minimum number of devices that can be operational at a given time, the client can know that the request was selected. If two or more clients attempt to request different functions at approximately the same time, the system may not select either request, in which case a leader can be requested to determine if any requests may have been selected, and to reestablish a safe proposal number. Systems with fewer devices can also implement the message-delay-reducing algorithm if they can also revert to the standard Paxos algorithm if an insufficient number of devices are operational. Such algorithms can be used to provide an efficient method for determining whether to commit or abort a client transaction.

A cardiac assist device synchronization system includes a cardiac assist device and an acoustic or accelerometer sensor that provides a signal input to the cardiac assist device indicative of aortic valve closure. The cardiac assist device is coupled to a mammalian aorta and includes an inflatable chamber and a fluid pump. A fluid conduit is in communication between the chamber and the pump to provide for selective inflation of the chamber. A pump controller triggers the pump in counter-pulsation to a mammalian heart upstream from the aorta. A process for synchronizing a cardiac assist device in counter-pulsation with a left ventricle includes locating an acoustic or accelerometer sensor within a thoracic cavity of a mammal having the assist device coupled to the aorta of the mammal. Through the measurement of an acoustic or acceleration property of an aortic valve of the mammal, and the transmission of aortic valve closure measurement through a controller for the cardiac assist device, counter-pulsatile synchronization for the cardiac assist device is achieved.

Synchronizing audio and video streams in packet-based networks requires synchronization of packet timestamps. The present invention provides such synchronization without resort to a network time standard. In one embodiment of the present invention, pairs of timestamp synchronized signals, such as audio and video signals, not having a common timestamp clock are mixed. One of the signals, for example, the audio signals, is mixed first while preserving the original audio timestamps. The preserved timestamp information is then used to synchronize the timestamps of the unmixed signals, in this example the video signals, to provide synchronization of all signals. In another embodiment, the present invention uses packets containing calibration of timestamps to reduce jitter. The present invention also includes specifications for a packet for transmitting timestamp information.
