Abstract: A stability detection system is provided for detecting the stability of an articulated vehicle. The stability detection system may include a weigh system configured to measure the weight distribution of the vehicle. A controller may provide a warning when the detected weight distribution exceeds a threshold.

Abstract: A fluid level measurement system for sensing fluid level in a tank is disclosed that includes a float that moves vertically in the interior of the tank, and a force measuring mechanism coupled to the float that generates an output based on the upward force on the float. The system can include an outer tube where the float is contained in the outer tube. A microcontroller can compute fluid level using the force measuring mechanism output. Altitude and other factors can be accounted for. Exemplary force measuring mechanisms can include a Hall Effect sensor sensing position of a magnet coupled to the float, or a force sensor coupled to the float. The length of the float, or the float and uncompressed spring can be substantially equal to the height of the tank. The float can have a generally uniform or non-uniform outside diameter.

Abstract: A vehicle lighting system in which a controller changes the intensity of a drive light and/or a work light as a function of a speed of the vehicle.

Abstract: A cooling system comprises a first cooling package, a second cooling package, and a fan control system. The first cooling package comprises a first fan and at least one heat exchanger to cool at least one fluid associated with the machine. The first fan is configured to rotate in a cooling direction and an opposite cleaning direction. The second cooling package comprises a second fan and at least one heat exchanger to cool at least one fluid associated with the machine. The second fan is configured to rotate in a cooling direction and an opposite cleaning direction. The fan control system is configured to alternate the first and second fans between a first cleaning mode and a second cleaning mode.
