Abstract: A motorized shade for covering an architectural opening comprising a roller tube and a shade material comprising an upper end attached to the roller tube and a lower end. The shade material at least partially comprises electrically conductive material and the roller tube comprises an electrically conductive material that creates an electrically conductive path between the conductive material of the shade material and the roller tube. The motorized shade further comprises a capacitive touch sensor electrically connected to the roller tube via at least one electrical contact, and a controller electrically connected to the capacitive touch sensor and adapted to detect a touch of the shade material via the capacitive touch sensor and in response generate a command.

Abstract: A motorized shade comprising a motor adapted to lower or raise a shade material for selectively covering an architectural opening based on a position of the sun. The motorized shade comprises a controller adapted to drive the motor phase according to a startup sequence by ramping up amplitude form an initial amplitude to a startup amplitude and ramping up frequency from an initial frequency to a drive frequency, drive the motor phase according to a full drive sequence to move the shade material by driving the motor phase according to a sinusoidal waveform at a set maximum amplitude and at a drive frequency, and drive the motor phase according to a wind down sequence by reducing frequency from the drive frequency to an end frequency and reducing the amplitude from the maximum amplitude to an end amplitude.

Abstract: An angle shift compensation system and method for controlling a sinusoidally driven motor to achieve efficient motion and reduced noise. The motor controller uses the angle shift compensation method to monitor the angle shift between a sinusoidal motor control signal configured to drive the motor and a feedback signal received from at least one position detector indicating the position of the motor rotor with respect to the motor stator. In response, the motor controller proportionally adjusts the amplitude of the motor control signal based on the monitored angle shift to maintain the angle shift substantially equal to an angle shift threshold.

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.
