  • Automatic torque calibration for roller shades
    Patent number: 9534442
    Abstract: A method that detects obstacles on a roller shade's travel that create excess torque by sensing the current draw from a motor and method by which the motor can calibrate itself to detect excess torque. During the roller shade's travel, it will record the instantaneous torque being generated at various points. For example, it will store the greatest value in the shade motor's non-volatile memory as the normal operating torque.
