A sensor may detect glare from a recorded image and a shade position of a motorized window treatment may be controlled based on the position of the detected glare in the image. A luminance of a pixel may be calculated in an image and a glare condition may be detected based on the luminance of the pixel. For example, the sensor may start at a first pixel in a bottom row of pixels and step through each of the pixels on the bottom row before moving to a next row of pixels. When the sensor detects a glare condition, the sensor may cease processing the remaining pixels of the image. The sensor may calculate a background luminance of the image by reordering the pixels of the image from darkest to lightest and calculating the luminance of a pixel that is a predetermined percentage from the darkest pixel.

An automatic door control system includes a door element that rotates in response to a change in position of a door, a first door position sensor configured to output a position signal based on rotation of the door element, a controller and a control device. The controller incudes memory containing a target position corresponding to an intermediate position of the door between maximally open and maximally closed positions of the door, and a processor configured to monitor a current position of the door based on the position signal and stop rotation of the door element when the current position matches the target position. The control device is configured to set the target position in the memory through a wireless communication link with the controller.

A closing hinge including a hinge body and a pivot reciprocally coupled to rotate around a first axis; a working chamber defining a second axis perpendicular to the first axis; a cam member unitary rotating with the pivot; a cam follower wheel sliding along the second axis between a position proximal to the rear wall of the working chamber and a distal position thereto; a thrust spring acting on the cam follower wheel. The cam member includes a first abutment element and a second abutment element respectively including a second curved portion and a third curved portion for selectively contacting the cam follower wheel in a respective single tangency point at a first and a second open positions and for contacting the wheel in two tangency points opposite with respect to the second axis at a closed position.

A shutter panel for an architectural opening is provided. The shutter panel may include a frame and a louver rotatably coupled to the frame. The louver may be automatically closable based on an angular orientation of the louver. The shutter panel may include a closure device operably associated with the louver. The closure device may be actuated based on the angular orientation of the louver. The shutter panel may include a damping device operably associated with the louver. The damping device may be actuated based on the angular orientation of the louver. The shutter panel may include a tension device operably associated with the louver.

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 to stop the rotation when the resistance of the potentiometer is indicative of a target position of the door.

A shutter assembly includes a frame with a pair of elongate side members and a pair of elongate cross members extending between the side members. The first side member includes an inwardly-facing frame surface in a region between the pair of cross members and further includes a frame-ledge extending inward beyond the inwardly-facing frame surface. The shutter assembly includes a shutter panel having a first stile pivotally coupled to the first side member of the frame, the shutter panel configured to swing between a closed position and an open position relative to the frame. The first stile includes a shutter recessed surface, and a shutter-ledge extending outwardly beyond the shutter recessed surface. For light-blocking purposes the shutter assembly is configured such that the shutter-ledge is positioned adjacent to the frame-ledge when the shutter panel is in the closed position.

A damper providing varying damping force is provided. The damper may include a housing and a rotary member rotatably received the housing. The rotary member may rotate within the housing between defined end points of travel to define an angular range of travel of the rotary member. An outermost surface of the rotary member may be spaced inwardly from an inner surface of the housing defined between the end points of travel to define a gap between the outermost surface of the rotary member and the inner surface of the housing throughout the angular range of travel. The gap may vary in dimension depending on a rotational position of the rotary member to provide varying damping rates within the angular range of travel of the rotary member.

A hinge for the rotatable movement of a closing element, such as a door, a window, a shutter or the like, between a closing position and an opening position, the closing element being anchorable to a stationary support structure, such as a wall, a floor, a frame or similar, includes a hinge body anchorable to the stationary support structure or the closing element, and a pivot defining an axis and anchorable to the closing element or the stationary support structure. The pivot and the hinge body are coupled so as to cause the closing element to rotate between the opening and the closing position. The hinge body includes a working chamber defined along the axis to house the pivot.

Methods and systems provide adaptive management of openings in spaces. An opening in a space may be managed using an adaptive management scheme which may include detecting one or more conditions and/or activities affecting the space, through the at least one opening, analyzing the detected one or more conditions and/or activities, determining one or more actions corresponding to the detected one or more conditions and/or activities based on the analysis, and causing application of the determined one or more actions. The actions may include adjusting the opening. In this regard, the adjusting may include closing, fully opening, or adjusting the amount of the opening.

A torsion spring counter balancing mechanism for a stacking panel shutter door includes one or more torsion springs one end of the or each torsion spring is fixable to a drive transmission shaft of the stacking panel shutter door, the drive transmission shaft being adapted to raise and lower the or each shutter of the stacking panel shutter door; and the other end of the or each torsion spring is fixable to a separate rotatable member of the stacking panel shutter door; whereby the mechanism is provided with means adapted to enable both the drive transmission shaft and the rotatable member to rotate, during opening and closing of the stacking panel shutter door, in such a manner as to cause respective ends of the or each torsion spring to travel at different speeds during the opening and closing sequence, which permits to keep the same size motor when panel numbers are varied.
