A motorized sheer shading system may move a sheer shade material between an open position, a closed position, and a view position. The shading system may move the sheer shade material from the open position to the closed position at a first average rotational speed, and from the closed position to the view position at a second average rotational speed. The shading system may automatically determine a control limit that corresponds to the closed position of the sheer shade material after control limits have been set for the open position and the view position. The shading system may cause the sheer shade material to stop moving once it reaches the closed position if the raise button of a remote control is still depressed, and may cause the sheer shade material to stop moving once it reaches the closed position if the lower button of the remote control is still depressed.

The present disclosure includes systems, methods, and articles of manufacture for controlling a door. In various embodiments, exemplary systems may include a controller that may initialize and/or reset a limit count. A controller may initialize and/or reset a limit count in response to detection by a first position sensor of a first target. A controller may further initialize and/or reset a limit count by incrementing the limit count in response to a signal from a gear tooth sensor until a second position sensor detects a second target, whereupon the controller may store the limit count.

A hardwired and wirelessly controlled motorized window shade system is presented that includes a plurality of motorized window shades that are connected by a cable, such as Ethernet cable, to a power panel and a hardwired control. Motorized window shades are also wirelessly connected to a wireless control through a gateway. This arrangement provides the motorized window shades with the advantage of receiving power and control signals through the cable, as well as giving the flexibility of being controlled through a wireless control.

A method to be used for controlling a screen (1) including a load bar (2), a flexible element (4) supporting the load bar, and at least one controlled member for winding the flexible member, in order to move the load bar (2) between a first high or low position and a second low or high position, the movement resulting from an angular movement of the winding member. The method includes at least one step in which the angular movement of the of the winding member (52) is controlled with a temporal set value ((t)) of the instantaneous angular position ((t)) of the winding member (52).

Systems, methods, and modes for controlling one or more roller shades in order to substantially synchronize and uniformly align a plurality of roller shades. Each shade comprises a roller tube, a shade material connected to the roller tube, a motor adapted to rotate the roller tube, and a controller. The controller is adapted to: drive the motor between a first limit position and a second limit position of the shade material at a first rotational speed; determine a run time it took the motor to move the shade material between the first limit position and the second limit position; using at least the determined run time, determine a second rotational speed for the controller to drive the motor between the first limit position and the second limit position within a predetermined run time; and set the motor to operate according to the second rotational speed.

A sensor and/or system controller may process an image multiple times at multiple resolutions to detect glare conditions. A glare condition threshold used to determine whether a glare condition exists may be based on the resolution of the image. When the resolution of the image is higher, the glare condition threshold may be higher. The sensor and/or system controller may organize one or more adjacent pixels having similar intensities into pixel groups. The pixel groups may vary in size and/or shape. The sensor and/or system controller may determine a representative group luminance for the pixel group (e.g., an average luminance of the pixels in the group). The sensor and/or system controller may determine a group glare condition threshold, which may be used to determine whether a glare condition exists for the group of pixels and/or may be based on the size of the group.

Motorized window treatment systems are disclosed. A motorized window treatment system may include a covering material, a sensor circuit, and a control circuit. The sensor circuit may be configured to generate sensor signals indicative of a position of the covering material. The control circuit may be configured to determine a present sensor state of the sensor circuit, determine a predicted sensor state for the sensor circuit based at least in part on a power-down position recorded at a first time and a final position recorded at a second time, compare the predicted sensor state with the present sensor state, and determine a present position of the covering material based on the comparison of the predicted sensor state and the present sensor state. Methods of adjusting a position of a covering material of a motorized window treatment also are disclosed.

A motorized window treatment may be configured to adjust a position of a covering material to control the amount of daylight entering a space. The motorized window treatment may include a DC power source for charging an energy storage element, such as a supercapacitor and/or rechargeable battery. The energy storage element may be configured to provide power for the operation of a motor used to adjust the position of the covering material. The energy storage element may discharge when providing power to the motor and may charge such that the current it draws from a battery is at a desired average current level that extends the lifetime of the battery.

An intelligent dual-drive curtain system, which includes a roll tube, wherein the roll tube is wound with curtain cloth, and one end of the curtain cloth is fixed with a lower beam. The roll tube is equipped with a tubular motor and a spring rod drive unit. The tubular motor includes a power supply, a circuit board, a driving motor, a reducer, and an output shaft. The spring rod drive unit is clamped with the output shaft, and the output shaft rotates synchronously with the roll tube. The output shaft is also fixedly connected to the rotation shaft of the reducer, and the reducer is fixedly connected to the rotation shaft of the driving motor. The rotation shaft of the driving motor is on the end far from the reducer and is connected to the rotation shaft of the driving motor. A magnetic ring is fixedly installed, and a Hall sensing unit is installed at any position along the circumference of the magnetic ring. The Hall sensing unit and the driving motor are both electrically connected to the circuit board, The circuit board is electrically connected to the power supply, which improves the speed of curtain opening and closing.

As described herein, a motorized window treatment may be configured to synchronize its covering material with other motorized window treatments if movement of the covering material has been delayed. The motor drive unit may receive a message including a command via wireless signals, and rotate a roller tube to adjust a present position of the covering material at an increased rate in response to determining that adjustment of the covering material in response to the command is delayed. The control circuit may determine a delay time between when the other motorized window treatments began to move and when the motor drive unit begins to move in response to the command. The control circuit may begin adjusting the present position of the covering material at a nominal rate in response to determining that the covering material is synchronized with the other motorized window treatments using the determined delay time.
