Abstract: A system for controlling the header speed of a windrower to a set point includes a variable displacement pump producing a variable outflow of hydraulic fluid for driving the header via two hydraulic motors, the system being characterized in that the pump is driven by a pulse width modulated (PWM) signal having a duty cycle that is dependent on the speed and the acceleration of the header. When the header speed falls outside a window or range of speeds centered at the set point, header speed is used to modify the duty cycle of the PWM signal and bring the header speed back within the window. In addition, the duty cycle of the PWM signal is decremented if the acceleration of the header exceeds a threshold and the header includes disk type cutters.

Abstract: A diesel engine preheat system includes a temperature sensor for sensing the temperature of the engine coolant, engine heaters for heating the engine, and a microprocessor for calculating the duration of a preheat cycle. When an ignition switch is turned on, the microprocessor samples the output of the temperature sensor to determine the initial engine temperature. The microprocessor computes the required heating time from the initial temperature and a stored parameter representing the relationship between increase in temperature and heating time of the engine. The microprocessor energizes a relay to connect the engine heaters to a battery for the computed time. During the preheat cycle the microprocessor decrements the computed heating time and energizes a visual display to display the time remaining in the preheat cycle.

Abstract: A system for indicating the level of a liquid in a container is operable with either an analog type liquid level sensor producing an output signal which varies linearly in magnitude with the level of liquid, or a digital liquid level sensor producing a cyclic pulse width modulated signal which varies in duration according to the liquid level. One or the other type sensor is connected to an analog wire and a microprocessor is programmed to detect positive and negative going edges of pulses on the wire and generate values representing the duration of the pulses. If pulse edges are detected, the microprocessor uses the generated values representing the duration of the pulses to access a conversion table and obtain a multi-bit value for energizing the display. If no pulse edges are detected, the magnitude of the signal on the analog wire is converted to an equivalent digital value which is applied to a second conversion table to derive a multi-bit value for energizing the display. The liquid may be a fuel and the container may be the fuel tank of a vehicle.

Abstract: The apparatus is an electronic speed control for farm machines. A microprocessor is fed data on the tractor engine speed, the tractor ground speed, and the manual speed lever setting, and electronically matches the desired ground speed to the engine speed to prevent stalling the engine. Ground speed is controlled by using the microprocessor to electrically vary a control valve that replaces the usual mechanical linkage between the speed control lever and the hydraulic pumps driving the hydraulic wheel motors.

Abstract: The cutter head of a windrower may carry a sickle bar or a disc as the cutting element. Each type of cutting element requires a different drive power to obtain a given set point speed. To determine the type of cutter being used, the magnitude of the signal required to bring the cutting element to a given set point speed is measured and compared to limits defining first and second, non-overlapping, ranges of signal magnitudes, one range being typical of sickle bar operation and the other range being typical of disc operation.

Abstract: A power failure protector circuit prevents spurious output signals from an electronic circuit when power to the electronic circuit is interrupted. The output of the electronic circuit is effectively blocked by a switch. The switch is turned off when the power supply is turned on and remains off until the power supply is interrupted. A capacitor is normally charged to the operating voltage of the power supply and when the power supply is interrupted, the capacitor discharges to turn the switch on during the interval when the operating voltages of the electronic circuit are decaying. The capacitor also provides a power source to maintain the operating voltages of the electronic circuit near normal for a short interval after the power supply is interrupted thus insuring correct operation of the electronic circuit until after the switch is turned on and the output from the circuit is blocked.
