摘要:
A persistent connection is used for real-time or near real-time data transfer from a push platform on a network to a mobile station. To establish and maintain the persistent connection between the mobile station and push platform on the network, various protocols are defined over a packet connection between the mobile station and push platform. The real-time or near real-time data is pushed or sent by the push platform to the mobile station, as the data becomes available from a data source. In particular, heartbeat messages are used to determine whether or not the persistent connection is alive and available for real-time or near real-time data transfer. When the persistent connection is lost, the mobile station uses a retry connection scheme based on the number of connection attempts made by the mobile station for establishing a new persistent connection to the push platform.

A fuel filler system for an automotive vehicle includes a filler pipe connected with a fuel tank and an interceptor mounted about an open end of the filler pipe, with the interceptor and filler pipe defining a generally annular contaminant collector having a drain extending from the collector. A filler cap closes both the open end of the filler pipe and the open end of the interceptor, so as to prevent ambient contamination from entering either the contaminant collector or the filler pipe. Removal of the filler cap from the filler pipe first causes venting of the fuel tank into the collector before a sealing condition between the filler cap and the interceptor is released.
摘要:
A decision management system simulates a communications network service deployment using business and technology changeable parameters, a base case model, a network cost model and a bandwidth model. The simulations may be performed for different sets of changeable parameters to generate multiple candidate solutions. These solutions are analyzed to identify a solution for deploying the communications network service.

Systems and methods for performing leak testing on fuel system components in hybrid vehicles during engine-off operating conditions are disclosed. For example, a fuel tank may include a pressure accumulator which may be filled with fuel via a fuel pump in order to generate a vacuum which may be used to diagnose leaks in the fuel system.

The present invention relates to document automation/assembly systems, and more particularly to document automation systems distributed over a network such as the Internet, and/or other communication networks. In addition, the present invention relates to methods, especially computer-implemented methods, to computer programs, and to recording media storing such programs for use in such systems.

A push messaging platform includes a push server system having push engines (PE) for maintaining persistent connections with mobile devices, and push controllers (PC) for maintaining records of mobile devices' connections. The platform provides high scalability by including a load balancer for distributing connection requests received from mobile devices across the PEs, and dispatchers for forwarding each received message to a PC associated with the mobile device identified in the message. The platform provides high availability by using local backup PCs and remote mirror PCs. A global registered process (GRP) on each PC is linked to a process on a backup PC, and the backup process replaces the GRP if the GRP fails. Local registered processes (LRP) on each PC are linked to corresponding processes on a remotely located mirror PC, and the mirror process replaces the LRP if the LRP fails.

A system for a vehicle is provided. The system may include a fuel tank including a first and a second interior region at least partially separated from each other. The system may further include a fuel pump including a pick-up positioned in only the first region and a passive-siphoning subsystem with a crossover-siphoning conduit communicating between the first and second regions, the conduit enclosing a wicking element.

A fuel storage system includes a fuel tank, a fueling receptacle in fluid communication with the tank, and a coil adjacent the fueling receptacle. The system also includes a controller configured to determine information about a state of fuel in the tank, and to cause a modulated current to be driven into the coil to generate an electromagnetic field. The modulated current represents the information about the state of fuel in the tank.

A fuel storage system includes a storage vessel including a dielectric liner, a voltage sensor formed by a pair of plates disposed on opposing surfaces of the liner, and a controller configured to determine a gas pressure in the storage vessel based on voltages measured by the sensor.
