Abstract: A method for controlling a drapery assembly is disclosed that opens and close a drape based on low and high touch sensitivity signature values that are established manually by the user. The method comprises pressing at least one button to initiate setting low touch sensitivity value; detecting a first manual movement of the drape; determining a first number of ticks using an encoder associated with the first manual movement; determining a low end user sensitivity signature value by calculating the average first number of ticks of the encoder; pressing at least one another button to initiate setting high touch sensitivity value; detecting a second manual movement of the drape; determining a second number of ticks using the encoder associated with the second manual movement; and determining a high end user sensitivity signature value by calculating the average first number of ticks of the encoder over the first time period.

Abstract: A motor calibration system and method for a motor having a rotor, a stator, and at least one phase. The system further comprises a controller and a position detector adapted to detect a position of the rotor with respect to the stator. Wherein the controller is adapted to perform a calibration sequence to calibrate to motor by driving at least one motor phase with a motor control signal at a predetermined maximum amplitude value in a first direction with substantially no load applied on the motor, receiving a feedback signal from the at least one position detector, and determining a first calibration angle shift by measuring a difference between at least the motor control signal and the feedback signal of the at least one motor phase. The controller accounts for the first calibration angle shift when driving the motor in the first direction during normal operation.

Abstract: A drapery track assembly is disclosed that performs an automatic and dynamic torque calibration to enable automatic detection of pulling of the drape as well as obstacles in order to minimize damage to the drapery track assembly and users. The drapery track assembly comprises a track, a drape attached to the track, a motor configured for moving the drape along the track, a sensor configured for sensing a position of the drape along the track, a current sensing circuit configured for detecting current levels, and a controller configured for controlling the motor and comprising at least one memory. The controller is configured for determining and storing a multi-point overcurrent threshold (OCTH) profile in each direction of travel comprising a plurality of overcurrent threshold (OCTH) values for each segment of travel along the track. The controller uses these multi-point overcurrent threshold (OCTH) profiles during normal operation to detect an overcurrent event and perform an overcurrent operation when a measured current level within a travel segment exceeds the overcurrent threshold (OCTH) value of that travel segment.

Abstract: A motorized roller shade that detects obstacles in its 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.

Abstract: A motor calibration system and method for a motor having a rotor and a stator and comprising at least one phase. The system further comprises at least one position detector adapted to detect a position of the rotor with respect to the stator and generate a feedback signal and a controller adapted to perform a calibration sequence to calibrate to motor. Wherein the controller calibrates the motor by driving at least one motor phase with a motor control signal at a predetermined maximum amplitude value in a first direction with substantially no load applied on the motor, receiving a feedback signal from the at least one position detector, and determining a first calibration angle shift by measuring a difference between at least the motor control signal and the feedback signal of the at least one motor phase. The controller accounts for the first calibration angle shift when driving the motor in the first direction during normal operation. According to one embodiment, the controller may determine a second calibration angle shift for a second direction in a similar manner. According to another embodiment, the may determine the second calibration angle shift using a transformation function and a predetermined angle shift sum constant.
