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 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.

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 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.

An apparatus (10) for winding a screen (12) comprises a winding drum (14) for winding the screen (12) which can rotate about an axis of rotation (16) with respect to a fixed frame of reference over more than one revolution between at least one first end-of-travel position and a second end-of-travel position, a motor assembly (30) comprising a motor (32) equipped with a stator (32.1) intended to be fixed to a fixed support (23, 26) and a rotor (32.2) kinematically connected to the winding drum (14). A first measurement assembly (51) comprises a first encoder (46) secured to the rotor (32.2), a first sensor for reading the first encoder (46) and generating a first counting signal when the first encoder (46) turns. First processing means (50) generate, as a function of the first counting signal, a first signal indicative of the position of the screen, which signal is monotonous when the drum moves from the first end-of-travel position to the second end-of-travel position. A second measurement assembly (64) makes it possible to detect at least one indexed position of the drum (14) per revolution of the drum in the fixed frame of reference. A calibration memory (56) stores at least one first calibration value for the first signal indicative of the position of the screen in the indexed position of the drum and at least one first quantitative algebraic comparison between a current value of the first signal indicative of the position of the screen as measured on passing through the indexed position during an observation phase and the first calibration value is delivered.

A window covering includes a movable window covering material, lift cords for moving the material, a lift cord take-up shaft for gathering and releasing lengths of the lift cords to move the window covering material, and a motorized lift assembly. The motorized lift assembly includes a motor assembly including a motor, a gear train drivingly connected to and operated by the motor, and a driveshaft drivingly connected to the gear train and to the lift cord take-up shaft. The gear train includes a plurality of planetary gear stages.

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.

Door curtains with position sensor switches are disclosed. An example door for selectively blocking and unblocking a passageway includes a frame to be adjacent the passageway. The example door includes a curtain moveable selectively to a closed position and a first open position, where the curtain blocks the passageway in the closed position, and the curtain unblocks the passageway in the first open position. The example door also includes a bracket to be attached to the frame. The bracket is movable selectively to a normal position and a displaced position relative to the frame. The example door further includes a switch to be attached to the bracket and in sensing relationship with the curtain. The curtain supports at least some weight of the bracket when the bracket is in the displaced position. The curtain supports no weight of the bracket when the bracket is in the normal position.

A motor drive system for operating a mechanism for raising and lowering window coverings includes a motor operating under electrical power and an electrically powered drive system. The motor drive system advances a continuous cord loop in response to positional commands from a controller. An input-output device includes a capacitive touch strip that receives user inputs along an input axis, and an LEDs strip aligned with the input axis. A group mode module communicates the positional commands to other motor drive systems within an identified group to operate respective other mechanisms of the other motor drive systems. A set control module enables user calibration of a top position and a bottom position of travel of the window covering. The input-output device extends vertically on the exterior of a housing for the motor drive system, and the housing supports input buttons of the group mode module and the set control module.
