In an embodiment, a system for managing window blinds is provided. The system comprises an electronic device and an application stored on the device that when executed directs, based on a stored schedule, blinds for a first group of windows in a room in a structure to execute a first action. The system also directs, based on the schedule, blinds for a second group of windows in the room to execute a second action. The system also directs, based on the schedule, blinds for the first and second groups to take a third action. The actions comprise at least one of opening slats, closing slats, opening the blinds, and closing the blinds. The application transmits the directions to the groups via at least one of Internet connection, WiFi connection, and other wireless connections via an intermediary device and via Bluetooth and transmits via Bluetooth without intermediary device.

A system incorporating a camera sensor situated in a room having walls with windows and sun blinds. The sun blinds may control outdoor light to the room. Indoor light sources may provide artificial light in the room. A controller may receive signals from the camera sensor. The controller may estimate a presence of occupants and provide control signals to the sun blinds and light sources. A room temperature sensor and an HVAC system may be connected to the controller. A preset temperature, which may depend on occupancy, in the room or zone may be achieved with various kinds of heating or cooling. At the same time, outdoor light and indoor artificial light may be controlled to obtain a preset intensity of lighting in the room, which may depend on occupancy, in a manner to achieve a minimum cost of energy used by the HVAC and the light sources.

A window shade includes a top box, a mediate bar, a bottom bar and a shade connected between the mediate bar and the bottom bar. A first scrolling unit and a second scrolling unit are located in the top box, and each are cooperated with a movable unit, a resilient member and a fixed member. The resilient member is connected between the movable unit and the fixed member. Each of the first scrolling unit and the second scrolling unit has a first roller and a second roller, and each of the movable unit has a third roller and a fourth roller. The first cords of the first scrolling unit are connected to the mediate bar. The second cords of the second scrolling unit extend through the mediate bar and are connected to the bottom bar. The first and second cords meet the requirements of a longer shade.

A motorized window treatment provides a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment includes a covering material, a drive shaft, at least one lift cord rotatably received around the drive shaft and connected to the covering material, and a motor coupled to the drive shaft for raising and lowering the covering material. The window treatment also includes a spring assist unit for assisting the motor by providing a torque that equals the torque provided by the weight on the cords that lift the covering material at a position midway between fully-open and fully-closed positions, which helps to minimize motor usage and conserve battery life if a battery is used to power the motorized window treatment. The window treatment may comprise a photosensor for measuring the amount of daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window. The position of the covering material may be automatically controlled in response to the photosensor and the temperature sensors to save energy, or may also be controlled in response to an infrared or radio-frequency remote control.

In one aspect, a headrail assembly for a covering for an architectural structure includes a headrail and a tilt wand coupled to the headrail. The tilt wand includes a proximal end and a distal end spaced apart from the proximal end. The tilt wand is movable relative to the headrail between an operating position at which the tilt wand is suspended relative to the headrail at the proximal end of the tilt wand and a stowed position at which a portion of the tilt wand extending between the proximal and distal ends of the tilt wand is supported relative to the headrail. In addition, the headrail assembly includes a rail clip configured to couple the tilt wand to the headrail when the tilt wand is at the stowed position. The rail clip includes retention structure configured to retain the portion of the tilt wand relative to the headrail.

A battery-powered device, such as a motorized window treatment, may provide power to an electrical load, such as a motor. The device may also include a control circuit and a communication circuit. In addition to the battery, the device may be configured to receive power from a supplemental power source, such as a solar cell or wireless RF power supply, through which to power the control and communication circuits. The device may include a voltage monitor and a switch to intelligently control whether the battery or the supplemental power source is powering the control and communication circuits.
