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.

A load control system may include control devices for controlling electrical loads. The control devices may include load control devices, such as a lighting device for controlling an amount of power provided to a lighting load, and input devices, such as a remote control device configured to transmit digital messages comprising lighting control instructions for controlling the lighting load via the lighting device. The remote control device may communicate with the lighting device via an intermediary device, such as a hub device. The remote control device may detect a user interface event, such as a button press or a rotation of the remote control device. The remote control device or the hub device may determine whether to transmit digital messages to as unicast messages or multicast messages based on the type of user interface event detected.

A method of operating a motorized window covering is presented wherein in response to a standard movement command power is supplied to a motor in a continuous or generally continuous manner thereby moving the shade material from a start position to an end position in a generally continuous manner. However, in doing so, the motor rotates at a fast rate thereby causing elevated noise levels. In response to an automated movement command, power is supplied to the motor by cycling power to the motor between a powered state and an unpowered state thereby moving the shade material from a start position to an end position in an incremental manner. While moving the shade material in this incremental manner is slower, it is substantially quieter. The preferred mode of operation is selected based on whether the movement command is a standard movement command or an automated movement command.

A control method according to the present disclosure causes a computer of an information apparatus to: display a display screen on the touch panel display, the display screen representing a floor plan of a building; display device icons representing target devices on the display screen representing the floor plan, the device icons including an icon representing an electric curtain device capable of opening and closing a curtain through a remote operation; display an operation screen including an image representing the curtain of the electric curtain device as overlapped on the display screen representing the floor plan, when selection of the icon representing the electric curtain device is sensed; and output a first open control command to the network when a pinch-out operation is sensed on the operation screen, the first open control command being for opening the curtain of the electric curtain device corresponding to the selected icon.

A wirelessly controllable, motorized and battery powered drapery apparatus is presented having a rotatable drive element having a guide structure in its surface. The rotatable drive is inserted through the open interior of a plurality of grommets in the shade material. A grommet driver is positioned over the rotatable drive element and connected to one of the plurality of grommets. The grommet driver has at least one tooth that is in communication with the guide structure in the rotatable drive element. As the rotatable drive element is rotated, the grommet drive is driven along the length of the rotatable drive element thereby moving the shade material between an open position and a closed position.

The present invention relates to a curtain control system and a curtain control method. When a controller receives a curtain-releasing signal, a braking module releases a curtain so as to lower it, a current position detecting module detects an absolute position of the curtain, and the controller calculates a current velocity and a current acceleration of the curtain according to a variation per unit time of the absolute position. When the current velocity is equal to zero or the current acceleration is smaller than zero, the controller controls a motor to lift the curtain or controls the braking module to hold the curtain at a current position. Accordingly, the present invention uses the absolute position to calculate the current velocity and the current acceleration of the curtain so as to determine whether the curtain has encountered an obstacle.

A system for opening and closing a curtain on a rod or rail, includes a driven wheel coupled to a motor within a housing and protruding from the housing in frictional engagement with the rod or rail and a suspension system including a plurality of support members, each of the plurality of support members configured for sliding or rolling contact with the rod or rail and a linkage extending along a suspension axis and connecting a support member of the plurality of support members to the housing to suspend the housing from the support member. During installation, the system is configured for the user to select the support member from the plurality of support members and to couple the support member to the housing, and the driven wheel is rotated by the motor to advance the housing along the rod or rail with the housing suspended from the support member.

A curtain control system, installed in a curtain, comprises a sensing module, a processing module, and a motor control module. When a processing unit of the processing module determines that a rotation angle common to a plurality of panel holders falls within a specific range or that a change in the rotation angle reaches a specific value, and the rotation angle is not equal to a preset angle, the motor control module drives a travel motor and a tilt motor to operate simultaneously. In this manner, the waiting time for curtain adjustment during user operation can be reduced.
