Abstract: A method for automatically planning and managing the performance of a communications network comprising a propagation forecasting step where propagation forrecast algorithms form a propagation forecast from weather inputs and a traffic forecasting step where traffic forecast algorithms form a traffic forecast from traffic data inputs and a network planning step where planning algorithms display an automated network model. During a forecast updating step, meteorological measurements and radio traffic measurements are continuously provided, resulting in adjusted propagation and traffic forecasts, which are then followed by a network realignment step to adjust the network. During a model comparison step, an artificial intelligence program continuously compares the model, the model adjustments, the realigned network and the network performance parameters with each other. A coefficient adjustment step adjusts the propagation, traffic and planning algorithms.

Abstract: A fuel delivery system for an internal combustion engine has a fuel tank with a piston movably mounted on a guide rod therein to separate the tank into two variable volumes, one for containing fuel and the other for containing pressurized air to act on the piston for compressably pressurizing the fuel, thus preventing fuel vaporization during normal fuel delivery. Pressurized air is provided to the pressure volume by an air regulator or a positive displacement pump, either of which can be controlled by a microprocessor based electronic engine control unit. A filler pipe attached to the tank has at least one anti-expulsion valve therein and pressure interlock means for preventing fuel expulsion through the filler pipe when the tank is pressurized. A pressure accumulator is connected to the fuel line to assist in providing a constant fuel pressure to the engine.
