A gaseous-fueled reciprocating internal combustion engine includes a carburetor having a throttle valve that is controlled by a speed governor. A proportional fuel control valve is disposed intermediate a fuel supply and the carburetor, and is controlled by an air fuel computing device. The computing device generates a control signal to adjust the fuel control valve based on a governor sensed variable indicative of engine speed, sensed engine torque, a governor output signal from the governor indicative of an opening position of the throttle valve wherein 100% corresponds to a wide open throttle position, and 0% corresponds to a closed position, and a lean combustion control map containing predetermined set point values stored in memory. During operation, the control valve is responsive to the control signal generated by the computing device for adjustment of a fuel flow therethrough so as to obtain a ratio of air to fuel provided to the engine that is substantially at a lean misfire limit of the engine, thereby reducing fuel consumption, NOx emissions, and reducing exhaust gas temperatures. Alternatively, the control signal is generated using engine speed alone.

A rotational sensor for use with an in-vehicle navigation system , a navigation system that uses the sensor, and a vehicle with the sensor installed. The rotational sensor is created by placing two gravitational accelerometers configured at 90 degrees with respect to one another and mounted at the center of a vehicle wheel. As this resulting sensor is rotated, sine and cosine signals with a quadrature relationship are generated with respect to the earth's gravity vector, from which both rotation and direction of rotation can be determined. These signals may then allow the counting of the turns of the wheel, thus estimating the distance and the rate at which the vehicle has moved. A self-contained version of this device including a transmitter can relay this information to a receiving unit located within the vehicle. When one of these devices is located on each of the steerable wheels of the vehicle, the relative heading-direction of the vehicle may also be estimated.

Orders received by an electronic trading system are processed in batches based on the instrument to which an order relates. An incoming order is assigned to a queue of a queue set that makes up the batch according to a random process.
