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.

The present disclosure relates to a method and a device for adjusting indoor illumination intensity. In the method, a target illumination intensity value is acquired when a target electric appliance is running and the target electric appliance is susceptible to illumination intensity in a room. In the method, a first indoor illumination intensity value in the room is collected, and an indoor illumination intensity adjustment device is controlled according to the first indoor illumination intensity value and the target illumination intensity value. The indoor illumination intensity adjustment device is controlled to change the first indoor illumination intensity value to achieve a second indoor illumination intensity value where the second indoor illumination intensity value conforms to the target illumination intensity value.

Disclosed is a method for implementing a television theater mode, including: detecting playback content played by a playback terminal in real time when the playback terminal is in a playing status; when detecting that the playback terminal is playing a video, detecting current statuses of theater sound equipment, lighting equipment, and a curtain; sending a sound-and-light control command to a theater sound system and a curtain control system based on the current statuses of the theater sound equipment and the curtain, to adjust a current playback environment as a sound-and-light environment of the television theater mode; reading the video resource being played, determining a video image brightness change based on the read video resource, and sending the sound-and-light control command to the lighting control system, to adjust brightness of the indoor lighting equipment based the video image brightness change. Further disclosed is an apparatus for implementing a television theater mode.

A retrofittable curtain apparatus capable of being installed onto existing curtain tracks comprising a curtain and curtain carriers. The apparatus may comprise a pair of latches on either side to facilitate simple installation onto the curtain track by clamping the apparatus to the track. A pair of switches located on either side of the apparatus allows a user to activate the apparatus by tugging on the curtain, pulling it taut over the switch thereby actuating it. The apparatus comprises an internal assembly of efficiently arranged gears and motors that produce a substantially small horizontal form factor, allowing for use with wave fold curtains.

A device for opening and closing a curtain on a rod or rail includes a driven wheel coupled to a motor within a housing. The driven wheel protrudes from the housing in frictional engagement with the rod or rail. The device further includes a suspension assembly including a support member and one or more linkages. The support member is in sliding or rolling contact with the rod or rail. The linkages extend along an independent suspension axis and connect the support member to the housing to suspend the housing from the support member, allowing the device to traverse bumps in the rod or rail. The driven wheel is rotated by the motor to advance the device along the rod or rail for opening and closing the curtain. A curtain opening system may further include one or more sensor targets disposed on the rod or rail, and an encoder and a sensor operatively connected to a controller of the device for auto-calibration of position tracking.

A control method is provided for controlling a networked information apparatus that includes a touch panel display. An electric shutter device is controlled over the network to open and close a shutter remotely. A processor of the information apparatus causes display of an operation icon on a display screen of the information apparatus, and the operation icon causes an operation screen for the electric shutter device to be displayed. When a swipe operation is sensed on the operation screen, a movement control command is output to the network for moving the shutter of the electric shutter device in a swipe direction of the swipe operation, in which movement of the shutter represented in the shutter image results in a changed representation of an object hidden by the shutter represented in the shutter image when the shutter image is in a closed position.

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.

Disclosed are methods and apparatuses for in situ control of smart or tinted windows. Also disclosed are methods and apparatuses for controlling at least one internal environmental condition for an interior space including at least one window.

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.

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.
