摘要： A circuit with two terminals that receive an input current. The circuit includes a sensor, and a controller to generate a modulated signal. The circuit also includes a flyback circuit that receives the modulated signal. The flyback circuit generates a first output voltage based on the modulated signal, shunts or redistributes at least a portion of the input current, and enables the controller to regulate the input current in proportion to the modulated signal.

摘要： A system for determining a quality and/or depth of a fluid in a tank. The system includes a controller, one or more transducers, and a temperature sensor. A fixed distance transducer transmits a sound wave toward a fixed surface. A depth transducer transmits a sound wave which reflects off a surface of the fluid. The temperature sensor senses a temperature of the fluid in the tank and provides an indication of the temperature to the controller. The controller measures the elapsed time for the sound waves to travel between the fixed distance transducer and a fixed surface and the elapsed time for the sound waves to travel between the depth transducer and the surface of the fluid held within the container. Using the elapsed times and the temperature of the fluid, the controller is able to determine a quality and the depth of the fluid.

摘要： A system for determining fuel usage within a jurisdiction includes a control computer operable to control fueling of an internal combustion engine and an auxiliary computer coupled thereto, wherein the auxiliary computer forms part of an operator interface unit. The control computer is operable to broadcast current fuel usage information in a number of fuel usage categories, and the auxiliary computer is operable to accumulate such fuel usage information within each jurisdiction traveled by the vehicle. In one embodiment, a GPS receiver provides the auxiliary computer with information relating to a current vehicle jurisdiction, and in an alternate embodiment, an auxiliary switch is provided wherein manual actuation of the auxiliary switch indicates entrance into a new jurisdiction. In either case, the auxiliary computer is operable to accumulate information relating to the total fuel used in a number of fuel usage categories, for each jurisdiction traveled by the vehicle, whereby this information is particularly useful in subsequently computing state fuel tax data.
