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.

The invention relates to a unit for covering and uncovering a surface using adjustable slats (3), comprising: for each slat (3), a set of two carriages (10.sub.1, 10.sub.2) guided in translation along guide tracks (8); a system (II) for moving the slats (3), comprising two movement motors (12) for each carriage pair (10.sub.1, 10.sub.2) equipping a slat, each motor being mounted in a different carriage; a system (I) for orientating the slats (3), comprising at least one orientation motor (14) for each carriage pair equipping a slat, said at least one motor being mounted in at least one of the carriages; and a control device for moving at least part of the slats in translation and orientating said slats.

A shutter assembly includes a shutter panel with a first and a second stile, each stile having a front stile-face and a rear stile-face. The shutter panel also includes a first and a second rail, the rails extending between the stiles, each rail comprising a front rail-face and a rear rail-face. In addition, the shutter assembly includes a stile bisection plane passes midway between the front and rear stile-faces, and a rail bisection plane passes midway between the front and rear rail-faces. The rail bisection plane is offset from the stile bisection plane.

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 control system for a shutter is disclosed. The shutter includes a force-bearing mechanism and a plurality of slats. The control system includes a power source, a driving device connected to the power source to output a first driving force, which drives the force-bearing mechanism to rotate the slats, and a clutch mechanism, which includes an input member and an output member which are drivable to be connected together for synchronous operation, or to be mutually disconnected for independent operation. When the driving device outputs the first driving force, the input member is engaged with the output member, and the first driving force can be transmitted to the force-bearing mechanism through the clutch mechanism to rotate the slats. When the driving device stops, the input member is disengaged from the output member, and the slats and the force-bearing mechanism are rotatable relative to the driving device.

A system for controlling a louver blind mobile panel that is moveable along a rail installed in a living space construct. The mobile panel featuring an inner volume capable of housing at least one motor that is functionally coupled to an electronics unit. The electronics unit is controlled with a wireless remove controller to control the activity of the at least one motor.

A fire damper actuation system in an HVAC system includes a damper system and an actuator system. The damper system includes damper blades rotatable between an open configuration and a closed configuration, a crank arm assembly configured to drive the damper blades, a spring assembly configured to be held in a loaded condition when the damper blades are in the open configuration, a temperature-activated fusible link, and a fusible link arm coupling the temperature-activated fusible link to the crank arm assembly. The actuator system includes a motor and a drive device. The drive device is coupled to the crank arm assembly and the temperature-activated fusible link. Operation of the drive device by the motor between a first end stop location and a second end stop location simultaneously rotates the crank arm assembly and the temperature-activated fusible link to complete a test inspection procedure.

Methods and systems provide adaptive noise management in a space. The adaptive noise management includes performing at least the steps of detecting when noise is present in the space, analyzing the detected noise, and taking one or more actions in response to the detected noise, based on the analysis of the detected noise. The one or more actions may include applying noise cancellation to mitigate, reduce, or eliminate effects of the detected noise, adjusting at one or more openings in the space, or a combination thereof.

A hinge for cold rooms or glass shutters, coupling a stationary support structure and a shutter movable between an open position and a shutter position, includes a hinge body having a working chamber; a pivot defining a first longitudinal axis coupled to the hinge body to rotate around the first axis between the open and the closed shutter position; a cam element integral with the pivot; a plunger element sliding in the working chamber along a second axis substantially perpendicular to the first axis, the plunger element having a slider with an operative face interacting with the cam element; and an elastic counteracting member acting upon the plunger element to move it along the second axis between a position proximal to the bottom wall of the working chamber and a position distal therefrom. The hinge body has a substantially plate shape.
