Abstract: A method and apparatus for determining the calibration characteristic of a sensor which produces an output signal which has a non-linear relationship to the value of a measured parameter. In one embodiment of the invention, the non-linear input/output characteristic of the sensor is represented by an equation of a curve. In another embodiment of the invention, the non-linear input/output characteristic is approximated by a series of straight lines which correspond to a series of ranges in the output signal. During periods of measurement, the output signal of the sensor is repeatedly sampled and used to calculate running totals of data sums which are subsequently used in combination with the characteristic parameters for the curve or series of straight lines for calculating the time integral of the measured parameter. The actual value of the quantity represented by the time integral is also measured by separate means.

Abstract: A cost effective and efficient method and apparatus for converting a "husk-off" corn picker into a "husk-on" corn picker to reduce kernel loss and damage. The husking bed of the "husk-off" corn picker is removed and replaced with a corn conveyor consisting of a series of driven flights which convey corn from one end of the picker to the other. The corn conveyor is set at an elevated angle so that the uptake end is lower than the deposit end of the conveyor. A suction fan is attached to the picker above the corn conveyor and sets of rubber air dams are placed around the conveyor to increase the effectiveness of the fan. An air inlet means is provided in the side of the picker so that the suction means can pull air under the corn conveyor and across the deposit end of the corn conveyor as the ears of corn fall from the conveyor. This directed air flow pulls the debris from the ears of corn as the ears fall and carry the debris into the suction means where it is blown out and away from the corn picker.

Abstract: A system and method for continuously measuring mass flow rate of grain in a harvester where an impact plate is disposed to be impacted by grain exiting a power driven conveyor which is a normal part of the harvester. The impact plate is mounted on force measuring apparatus which generates an electrical signal proportional to grain impact force. Computing apparatus in electrical communication with the force measuring apparatus calculates the average value of grain impact force, adjusts this value to compensate for the difference between an actual measured operating speed of the conveyor and a constant reference speed, and calculates grain mass flow rate utilizing a mass flow calibration characteristic which relates grain mass flow rate to average grain impact force, where this calibration characteristic is non-linear and has different values for different grain types and different grain moisture contents.
