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 fire shutter control system and a fire shutter control method capable of effectively controlling a fire shutter in the event of a fire in a building are provided. The fire shutter control system may include a fire detector configured to detect a fire outbreak and generate a fire signal in the event of a fire; a fire shutter controller configured to apply a control signal to a fire shutter to enable a drive motor for operating the fire shutter to operate when the fire signal is generated by the fire detector; and a power supply unit configured to supply power to the fire detector, the fire shutter controller, and the drive motor for operating the fire shutter.

A load control system automatically controls the amount of daylight entering a building through at least one window of a non-linear faade of the building. The load control system comprises at least two motorized window treatments located along the non-linear faade, and a system controller. The controller is configured to calculate an optimal position for the motorized window treatments at each of a plurality of different times during a subsequent time interval using at least two distinct faade angles of the non-linear faade, such that a sunlight penetration distance will not exceed a maximum distance during the time interval. The controller is configured to use the optimal positions to determine a controlled position to which both of the motorized window treatments will be controlled during the time interval and to automatically adjust each of the motorized window treatments to the controlled position at the beginning of the time interval.

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 method for controlling a maneuvering device (2) to maneuver a screen (3) of an occulting home-automation system (1) between at least a first position and a second position comprises: a first actuator (5) equipped with a first electric motor (9), a torque detection device (19) and a position management module (27), a second actuator (6) equipped with a second electric motor (12), a torque detection device (26) and a position management module (28), and a winding shaft (7). The actuator and the second actuator are configured to drive the winding shaft. The method includes designating the first actuator as master actuator and the second actuator as slave actuator.

An automatic door opening system includes an element that is rotatable to change a position of a door. A potentiometer is coupled to the element such that rotation of the element in one direction increases a resistance of the potentiometer and rotation of the element in the opposite direction decreases the resistance. A controller is configured to rotate the element concurrently with monitoring the resistance of the potentiometer, and stop the rotation when the resistance of the potentiometer is indicative of a target position of the door.

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.

A clock comprises an alarm clock housing having a front face, a clock display occupying at least a portion of the front face, a control on the housing for activating a shade positioning function, and a processor within the housing. The processor is responsive to the control for generating at least one shade positioning command to be transmitted to at least one motorized window shade, so as to cause the motorized window shade to move to one or more position at one or more corresponding predetermined interval relative to an alarm time.

A motorized roller shade configured to connect to a power-over-Ethernet network includes a motor for rotating the shade to roll and unroll shade material to and from a roller tube to raise and lower the shade. A bank of ultra-capacitors positioned in the roller tube provides power to the motor and to logic and control circuitry also positioned within the roller tube. The logic and control circuitry charges the ultra-capacitors though power derived from the power-over-Ethernet network, without any power-over-Ethernet switches in the network to provide additional power, and controls the operation of the motor to achieve a desired target velocity. Synchronized operation of multiple motorized roller shades is achieved though autonomous operation of the shades by their corresponding logic and control circuitry. In exemplary embodiments, a lighting element controlled by the logic and control circuitry allows controlled lighting of the shade.
