Patent ID: 8912808

Claim:
A method of tuning an actuator controller, comprising: driving an actuator to a first stop position by a driving signal; incrementally, until a measured capacitance of the actuator indicates the actuator has moved from the first stop position to a first endpoint: applying the drive signal toward a second stop position, measuring capacitance of the actuator, and comparing the measured capacitance of the actuator to a first threshold to determine whether the actuator has moved to the first endpoint; storing a code associated with the drive signal that moved the actuator to the first endpoint as a first end of a response curve for the actuator; incrementally, until the measured capacitance of the actuator indicates the actuator has moved from the first endpoint to a second endpoint: applying the drive signal toward the second stop position, measuring capacitance of the actuator, and comparing the measured capacitance of the actuator to a second threshold to determine whether the actuator has moved to the second endpoint; storing a code associated with the drive signal that moved the actuator to the second endpoint as a second end of the response curve for the actuator.
