A louvre shutter comprising louvres 20 rotatably mounted in a frame on louvre axles, and a louvre drive system that, in summary, comprises a rack and pinion gear system including an externally operable rack assembly and a set of pinion gears 28 mounted to the louvre axles. The rack is externally operable rack and is reciprocably mounted in the drive system housing 42, 48. The pinion gears 28 mounted to the louvre axles are engaged with the rack such that reciprocation of the rack rotates the louvre 20 relative to the frame.

A panel-and-frame assembly includes panel pivotally connected to an integrated frame. The panel includes a leaf extending on an external side and an axle extending on and along an edge of the leaf The leaf is made with a width smaller than a diameter of the axle. The integrated frame includes a channel extending in an internal side of the integrated frame and including a slit in communication with a recess. The recess receives the axle. The slit is made with a width smaller than the diameter of the axle to keep the axle in the recess. The width of the slit is larger than thickness of the leaf to allow pivoting of the panel relative to the integrated frame between an opening position and a closing position.

The opening-closing control system includes an outputter that outputs a control signal for controlling an operation of an opening-closing member configured to open and close an opening provided in a first facility, and an obtainer that obtains alert information on an alert from a second facility different from the first facility. Then, the outputter outputs the control signal for controlling the opening or closing of the opening by the opening-closing member based on the information.

A dimmer mechanism is movable by a motor that is powered by solar-charged supercapacitors between a first configuration, in which the dimmer mechanism blocks little of the interior of a skylight tube to maximize light throughput into a room, and a second configuration, in which the dimmer mechanism blocks more of the interior of a skylight tube to reduce light throughput into the room.

A mechanism (A) that is used in moveable facades and shutter systems, garage doors and access systems is provided, allowing opening and closing of panels (P) positioned between rail profile (10) and lower rail (R).

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.

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.

A closure system including a curtain configured to seal an opening, a wireless network having a plurality of channels, at least one transmitter coupled to the curtain and configured to communicate over the plurality of channels, and an operator operatively coupled to the curtain and configured to communicate over the plurality of channels, the operator and the at least one transmitter configured to communicate with each other over a selected one of the plurality of channels based upon communication interference detected on one or more channels.

An improved bi-fold shutter that includes a more efficient coupling mechanism at a hinge point suited to facilitate opening and closing the bi-fold shutter with greater ease. In one embodiment, the shutter may be designed for a window such that the shutter, when closed, is relatively close to the face of the associated window, and when open, forms an awning or overhang. The shutter includes an improved coupling mechanism at a hinge point between a first shutter portion and a second shutter portion. The improved hinge point shifts a direction of force needed to maneuver the shutter when moving the shutter from one position to another. The shift in opening and closing force directions improves the efficiency by which the shutter can be operated. In some embodiments, the shutter may be hand-operated. In other embodiments, the shutter may be powered.

A device control system includes: a touch panel that receives an execution instruction for scene control that operates at least part of a plurality of devices disposed in a facility in order to approximate an inside of the facility to a predetermined indoor environment; a controller that performs the scene control when the execution instruction for the scene control is received by the touch panel; and a communicator and an obtainer that obtain at least one of information indicating an environment condition in the facility or outside the facility, prediction information of the environment condition in the facility or outside the facility, and information about timing. The controller changes a content of the scene control according to the information obtained by the communicator and the obtainer.
