Patent ID: 6952944

Claim:
A method for automatically providing zero correction to a sensor reading, said method comprising the steps of: sensing a current position of a control linkage to determine a first value; coupling a sensor to the control linkage set in a starting position; sensing an initial position of the sensor when coupled with the control linkage in the starting position; adjusting the first value by a zero-offset value to calculate a second value; and determining the zero-offset value based on the initial position; storing the zero-offset value in a memory device; if the first value is greater than or equal to the zero-offset value, then determining the second value by subtracting the zero-offset value from the first value; and if the first value is less than the zero-offset value, then determining the second value by subtracting the first value from the sum of the maximum value and the zero-offset value; and providing an output signal based on the second value.
