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.

A hinge for the rotatable movement of a door or a similar closing element anchored to a wall or to a similar stationary support includes a fixed element adapted to be coupled to the wall or similar stationary support and a movable element adapted to be coupled to the door or similar closing element. The fixed and movable elements are coupled to mutually rotate around a first longitudinal axis between an open position and a closed position. The hinge further includes a hydraulic duct with a calibrated passage for s working fluid and an adjustment system acting thereon to control the movement of the door or similar closing element.

Described is a louver having a frame that forms an enclosure defining an opening, and a plurality of louver blades disposed within the opening. Each of the plurality of louver blades include a catch member that longitudinally extends between a first blade end and a second blade end of a corresponding louver blade. The louver may also include a rotation assembly configured to rotatably couple with the plurality of louver blades and the frame. The plurality of louver blades may autonomously rotate about rotation members of the rotation assembly based on environmental elements captured in the catch member such that the plurality of louver blades are configured in an open position in response to no water in the catch member and are configured in a closed position in response to an amount of environmental elements in the catch member.

In one aspect, a shutter assembly includes a shutter frame and a plurality of louvers supported by the frame. The shutter assembly also includes a louver drive assembly and a motor positioned within the frame. The motor is configured to rotationally drive a drive shaft extending within the frame. Additionally, the shutter assembly includes a clutch assembly rotationally coupled between the drive shaft and the louver drive assembly. The clutch assembly is configured to disengage or decouple the drive shaft from the louver drive assembly when a torque transmitted through the clutch assembly exceeds a given torque threshold.

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.

A door braking system includes: a shaft; a brake pad configured to be mounted to the shaft; a plate for mounting on the shaft adjacent to the brake pad; a spring for urging the plate to the brake pad, the spring configured to be mounted on the shaft; a nut dimensioned and sized to be mounted on the shaft for adjusting an amount of force the spring urges the plate against the brake pad. A method of applying variable amount of braking force to a door includes: attaching a brake pad and brake plate to a shaft; configuring a spring to urge the brake plate against the brake pad; mounting an adjustment piece to the shaft; and configuring the adjustment piece to move axially on the shaft as the shaft rotates to thereby vary a force the spring urges against the brake plate.

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 lockdown barrier system and method includes a first mount that is secured to a wall surface and a sheet of shielding material formed of an anti-ballistic material that is moveable between a retracted position and an extended position. The sheet of shielding material has a first end that is secured to the first mount and a second end opposite the first end that is freely moveable away from the first mount. The system includes a second mount that is secured to the wall surface at a location that is spaced from the first mount. The second end of the sheet of shielding material is releasably connectable to the second mount and is secured proximate to the first mount when in the retracted position. The second end is secured to the second mount when in the extended position.

A system for guidance and deployment of active panels on a building. One or more guide rails are coupled to a building wall. Panel units are coupled to the guide rails. An active panel can extend and contract from each panel unit. A control system conveys the panel units to an operational position on the building wall. When a panel unit is in operational position, The control system extends or retracts the respective active panel from the panel unit, and adjusts the angle of the panel unit relative to the building wall.

An adjustable door braking system includes a shaft, a brake pad configured to be mounted to the shaft, a plate for mounting on the shaft adjacent to the brake pad, a spring for urging the plate to the brake pad, an adjustment piece, and a seat. The spring is configured to be mounted on the shaft. The adjustment piece is dimensioned and sized to be mounted on the shaft for adjusting an amount of force the spring urges the plate against the brake pad. The seat allows the adjustment piece to move axially along the shaft and limit the adjustment piece from rotating with the shaft. The seat is movable between an engaged position where it contacts the adjustment piece to prevent rotation of the adjustment piece and a disengaged position where it does not contact the adjustment piece.
