摘要:
A server-side adaptive streaming capability is provided. The server-side adaptive streaming capability supports adaptive streaming of a data object from a server toward a client via a Transmission Control Protocol (TCP) connection between the server and the client. The server has access to a plurality of versions of the data object having a respective plurality of encoding bit rates associated therewith. The server has a TCP congestion control mechanism running for the TCP connection. The TCP congestion control mechanism has information associated therewith. The server determines, using the information associated with the TCP congestion control mechanism running on the server for the TCP connection, a transmission bit rate expected to be supported by the client for the TCP connection. The server selects, based on the transmission bit rate expected to be supported by the client and the encoding bit rates associated with the versions of the data object accessible to the server, one of the plurality of versions of the data object for propagation from the server toward the client via the TCP connection. The server dynamically switches between the versions of the data object as the transmission bit rate expected to be supported by the client changes.

A resilient data transfer capability is provided. The resilient data transfer capability is provided in a system including active and backup servers configured for supporting a TCP connection to a client. The resilient data transfer capability provides for continuation of the TCP connection with the client, using the backup server, upon failure of the active server, thereby enabling continuation of a TCP data transfer to the client via the TCP connection when the active server from which the client is downloading the data fails during the middle of the TCP data transfer. In this manner, the resilient data transfer capability enables the backup server to assume responsibility for the TCP connection from the active server without causing any associated problems (e.g., without resetting the TCP connection or causing any client side errors).

Systems and methods for reinforcing an existing pipeline. In some embodiments, the methods include positioning a pipeline wrapping apparatus on the existing pipeline, wherein the pipeline wrapping apparatus comprises a winding head, feeding a strip of material through the winding head, attaching an end of the strip of material to the existing pipeline, and helically wrapping the strip around the existing pipeline by rotating the winding head and axially translating the winding head relative to the existing pipeline.

A system for providing an automated axial force to a continuously variable transmission (CVT) in a wheelchair. An electronic transmission control receives one or more input signals generated by throttle position or other variables. The microprocessor generates an output signal that adjusts the axial force applied to a CVT thereby automatically adjusting the input to output ratio. The invention also provides a manually-controlled variator is designed for use on a wheelchair. The manual shifter hydraulically adjusts an axial force imparted on a variator in communication with a wheelchair wheel and a hand rim. Application of the axial force causes the hand rim input and wheelchair wheel output ratio to change, permitting a wheelchair operator to manually adjust the input to output ratio to more easily operate the wheelchair.

An air filter has an inner filtering body within an outer filtering body. The air filter is configured to fit inside a scoop and adjacent to the inlet opening of the scoop. By placing the air filter adjacent to the inlet opening of the scoop, the size of the air filter may be increased as compared to a traditional air filter which fits within the neck area of the scoop. As such, the surface area of the air filter may be increased to provide more air to an air intake system such as a carburetor, fuel injectors, throttle body, or the like, as compared the traditional air filter. The inner filtering body may be recessed inside or protrude from the outer filtering body. The inner filtering body may be coupled to the outer filtering body along the base of the air filter. The inner filtering body increases the surface area of the air filter so that more air may be provided to the air intake system of a vehicle.

The present invention is directed towards a kit for improving the repair of a transmission. The kit contains the components in a fashion that is well organized. Further, while some individual components are stored in the kit, others are preassembled into subassemblies. For example, a subassembly can be preassembled to factory level tolerances. Thus, during the repair, the defective subassembly can be removed and the preassembled replacement can be installed. This saves a great amount of time for the repair. It also makes the refurbished transmission less likely to fail. If the kit contains all of the transmission parts, then it is likely that all or only a portion of the parts will be used during the repair. In the event that all parts are not used, the repair man can place the unused parts back into the kit, along with the used parts, and the kit can be returned for a partial refund or a credit.
摘要:
A NFC enabled device to couple inductively to the H field of an RF signal and a regulator to regulate a voltage derived from an RF signal inductively coupled to the inductive coupler. The regulator has at least one voltage controlled impedance having a switch on voltage. A regulator controller provides a control voltage to each voltage controlled impedance such as that the control voltage is not less than the switch on voltage of the voltage controlled impedance.

The present invention relates to an integrated circuit bidirectional switch formed from bipolar transistor devices, in which the saturation voltage is sought to be reduced. More specifically, an integrated NPN bipolar transistor is formed with oxide insulation, and the normal direction of current flow is from the emitter to collector, and an integrated PNP bipolar transistor is formed with oxide insulation, and the normal direction of current flow is from the collector to emitter.

An analogue switch formed on a semiconductor substrate has input and output ports, and a first enhancement mode MOS transistor formed in an isolated well in the substrate material and having its gate connected to receive a control signal, and having one end of its conducting channel and its well connected to the input port. A second enhancement mode MOS transistor is formed in an isolated well in the substrate, and has one end of its conducting channel and its well connected to the input port (204), and has its gate connected to the other end of the conducting channel of the first transistor. A third enhancement mode MOS transistor is formed in an isolated well in the substrate, and has its gate connected to receive the complement of the said control signal, and has its conducting channel connected between the output port and the other end of the conducting channel of the second transistor, and has its well connected to one of the supply lines of the switch. Control circuits are connected to the gate of the second transistor for maintaining the second transistor in an opposite state to that of the first transistor.
