A system includes a plurality of sensors measuring a physical parameter; a processing unit communicatively coupled to the plurality of sensors and configured to receive sensor data from each of the plurality of sensors; wherein the processing unit is further configured to compare rates of change between sensor data for each individual sensor of the plurality of sensors and each of the other individual sensors of the plurality of sensors; wherein the processing unit is further configured to perform a first action when the rate of change of each of the plurality of sensors is within a first threshold of all of the other plurality of sensors; and wherein the processing unit is further configured to perform a second action when the rate of change of at least one of the plurality of sensors is not within the first threshold of at least another of the plurality of sensors.

Filter activation and deactivation based on comparative rates

An embodiment described herein includes a method for input channel voting. The method includes steps for sorting the three input values by magnitude into a high input value, a middle input value, and a low input value. The three input values are then tested. The testing includes subtracting the middle input value form the high input value to calculate a first difference, and comparing an absolute value of the first difference to a failure threshold. A first intermediate value is determined based on the comparison of the first difference to the failure threshold. The testing also includes subtracting the middle input value from the low input value to calculate a second difference, and comparing the second difference to the failure threshold. A second intermediate value is determined based on this comparison. The first intermediate value and second intermediate value are averaged to produce an output based on the three input values.

System and method for three input voting

A proximity sensor for determining the gap between a sensor and a metal target which is insensitive to noise, changes in temperature of the sensor and different lengths of wire by measuring the AC conductance, DC conductance and susceptance of the sensor and using the measured values with a predetermined data base to derive the desired gap distance.
