A load control system may include control devices for controlling power provided to an electrical load. The control devices may include an input device and a load control device. The load control system may include a hub device. The hub device may include a communication circuit and a control circuit. The communication circuit may be configured to receive a digital message from the control device. The control circuit may be configured to determine, based on content of the digital message, whether the control device has experienced a power removal event. The hub device may send, via the communication circuit, a power removal event indication to the control device of whether the control device has experienced the power removal event.

A motor driven system for raising and lowering a window covering executes motor ramp trajectory speed control. The motor ramp trajectory limits acceleration of an external motor from the idle (stationary) state to full operating speed, and limits deceleration of the motor from full operating speed back to the idle state. This function reduces stresses on a continuous cord loop drive mechanism. A control system manages solar heating effects in response to sunlight entrance conditions such as system sensor outputs, external weather forecasts, and other data sources. The system automatically opens or close the window covering to increase or decrease admitted sunlight under appropriate conditions. The input interface of the control system includes a visual display and input axis, which are aligned vertically if the window covering mechanism raises and lowers the window covering, and are aligned horizontally if the window covering mechanism laterally opens and closes the window covering.

A seal apparatus for a window shade having a first side seal on one side of a window and a second side seal on an opposite side of the window. The side seals have a base anchored to a side of a window frame, and an extensible sealing portion coupled to the base and being extensible toward the window shade to enclose a volume between the window and the window shade.

A seal for a multiple-shade window covering array. The seal includes two or more coextensive shades for a window in a window frame. At least one of the shades is a cellular shade. Each shade operates independently without interference from other shades, and each shade has different light properties such that selectively raising and lowering one or more of the shades changes a light property for the window covering array. The seal also includes side seals anchored to the sides of the window frame.

A motorized shade assembly includes a motor assembly operably connected to adjust a position of a covering relative to an architectural opening, a bracket assembly for supporting the motor assembly relative to the architectural opening, and a control wand assembly coupled to the motor assembly by a ball and socket connection, wherein one of a ball joint or a socket is coupled to a portion of the motor assembly, and the other of the socket or the ball joint is coupled to the control wand assembly, the socket receives the ball joint to selectively connect the control wand assembly to the motor assembly.

An event automation system controls building management systems (e.g. building automation, access control, and/or security systems of a building) for scheduled events. An occupancy module generates occupancy information for event spaces where events are scheduled via occupancy sensors installed at the event spaces. A building automation module instructs distributed devices of the building management systems to control the environmental settings of the event spaces based on the occupancy information and stored space, attendee, and schedule information. The event automation system also facilitates scheduling the events at event spaces of the building based on configuration information from an event organizer (e.g. invited attendees, start and end times, and activities to be performed at the event), required automation features for the event, location information and exercise preferences for the invited attendees, and/or aggregated usage information for the event spaces.

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 overhead roll-up door assembly having a door controller, a door panel and a drum on which the door panel is wound and unwound to open and close a doorway, opening and closing of the door being controlled by the controller. The door assembly includes a safety system comprising at least one light, the at least one light being positioned to emit light proximate a first side of the doorway, the light from the at least one light being projected onto a lower boundary of the doorway and forming a strip or stripe proximate the first side of the doorway, wherein emission of the light from the at least one light is controlled by the controller in conjunction with the controller opening and closing the doorway.

A remote control for a wireless load control system, the remote control comprising: a housing having a front surface and an outer periphery defined by a length and a width; an actuator provided at the front surface of the housing; a wireless transmitter contained within the housing; and a controller contained within the housing and coupled to the wireless transmitter for causing transmission of a wireless signal in response to an actuation of the actuator, the wireless transmitter and the controller adapted to be powered by a battery contained within the housing; wherein the length and the width of the housing are slightly smaller than a length and a width of a standard opening of a faceplate, respectively, such that the outer periphery of the housing is adapted to be received within the standard opening of the faceplate when the housing and the faceplate are mounted to a vertical surface.

An automated fire or smoke curtain/blinds system (2) includes a pelmet or a hood (4) adapted to be mounted on a wall or top of a windowpane, at least one motor (6) connected to at least one curtain/blinds holding device (10) such that the curtain/blinds 5 holding device (10) rolls when the motor (6) is operated, at least two curtain/blinds holding device wherein each curtain/blinds holding device are connected by a shaft or ball bearing, a movable curtain or blind with width of at least 8 meters attached to at least two curtain/blinds holding device, a movable curtain or blind (14A) of a predefined width and at the end of which is a bottom rail (14B), wherein the movable 10 curtain (14A) includes an self-closing escape door (14C) embedded within coverage area of the movable curtain (14A), and a control panel (16) to control up/down movement of the movable curtains.
