A load control system automatically controls the amount of daylight entering a building through at least one window of a non-linear façade of the building. The load control system comprises at least two motorized window treatments located along the non-linear façade, and a system controller. The controller is configured to calculate an optimal position for the motorized window treatments at each of a plurality of different times during a subsequent time interval using at least two distinct façade angles of the non-linear façade, such that a sunlight penetration distance will not exceed a maximum distance during the time interval. The controller is configured to use the optimal positions to determine a controlled position to which both of the motorized window treatments will be controlled during the time interval and to automatically adjust each of the motorized window treatments to the controlled position at the beginning of the time interval.

The disclosure discloses a return device and a windproof roller shutter formed by the return device. The return device includes an end cover, wherein a sliding chute is arranged on the end cover, the sliding chute is arranged slantly, and a horizontal height of a first end of the sliding chute is larger than a horizontal height of a second end of the sliding chute; a sliding component, wherein the sliding component moves along the sliding chute; and a fixed plate mounted at one end of a reel pipe, wherein the sliding component is mounted on the fixed plate. The windproof roller shutter includes a reel pipe, a shutter body, a low rail, two side rails and two return devices.

A rolling shutter driving device includes a motor, a locking assembly and a gearbox. The motor includes a stator and a rotor. The rotor includes a rotary shaft connected to the gearbox. The rotary shaft drives through the gearbox a rolling shutter to extend or retract. The locking assembly includes a brake pad slidingly fitted on the rotary shaft and a rotary member fixedly mounted to the rotary shaft. The brake pad is circumferentially fixed relative to the stator. The brake pad is slidable relative to the rotary shaft so as to be selectively engaged with the rotary member to lock the rotary shaft and hence hold the load in position, or disengaged from the rotary member to unlock the rotary shaft.

An optoelectronic component includes a carrier, and a light source arranged on a surface of the carrier, said light source including at least one luminous surface formed by at least one light-emitting diode, wherein a transparent converter-free spacer is arranged on the luminous surface such that a distance is formed between the luminous surface and a spacer surface of the spacer facing away from the luminous surface, and wherein the light source is potted by a potting compound such that the spacer surface is formed extending flush with a potting compound surface facing away from the surface of the carrier and a surface formed by a spacer surface and the potting compound surface is plane.

A clutch assembly for a roller door operator, the clutch assembly providing selective engagement with a drive wheel, the clutch assembly comprising: a rotatable shaft rotatable relative to the drive wheel; a clutch disc supported in a clutch lever and arranged to rotate with the rotatable shaft, the clutch disc and clutch lever configured to rotate relative to one another around the axis of rotation of the shaft; and a clutch cam supported in a clutch base, the clutch base configured to permit operative rotation of the clutch cam around the axis of rotation of the shaft in a first direction; wherein the clutch lever is operatively associated with the clutch cam so that rotational movement of the clutch lever in a second direction opposite to the first direction actuates movement of the clutch disc and the clutch lever axially along the rotatable shaft to engage or disengage the clutch disc with the drive wheel, and subsequent rotational movement of the clutch lever in the first direction actuates rotational movement of the clutch cam relative to the clutch base in the first direction.

A door, in particular a high-speed industrial door, with an intelligent door leaf is disclosed. The door has a door leaf which is guided by lateral guides and covers a door opening, and which has a first and a second side, a driving means for moving the door leaf between an open and a closed position, a door control means for controlling the driving means, as well as an electrically self-sufficient door leaf means arranged in the door leaf. The door control means also has a first communication unit. In addition, the door leaf device comprises at least one sensor unit for detecting at least a physical quantity, an energy converter which converts non-electrical energy into electrical energy, a second communication unit and at least one actuator unit. The first and second communication units communicate wirelessly with each other.

The invention concerns a lock unit, comprising a lock assembly having a locking element and a drive receiving portion operatively associated with the locking element and a drive unit connected to the lock assembly, the drive unit having a motor and being configured to move the locking element of the lock assembly from a locked position to an unlocked position, the drive unit including a driving element that interfaces with the drive receiving portion of the lock assembly to move the locking element from the locked position to the unlocked position, wherein the drive unit is selectively separable from the lock assembly. The invention facilitates fitment of the lock assembly in position, provides a more compact and secure solution, and assists in regard to maintenance.

A slat system having a slat hanging with slats and a shifting apparatus for shifting the slats. The slats are intercoupled and movable from a closed position, in which broad faces of the slats are substantially flush in a plane and narrow faces of adjacent slats face one another, into an open position, in which the broad faces of the slats are parallel to one another but not parallel to an opening and closing direction, using the shifting apparatus to shift the slats in the opening and closing direction. The shifting apparatus has a pulling means coupled at one end to the slat hanging. The slat system has a first sheave mounted so as to be rotatable about an axis in two directions, to which sheave the other end of the pulling means is fastened, and a locking means to block the sheave from rotating in the open position.

The present disclosure relates to a barrier system for shielding humans from harmful exposure to fire, smoke, noxious fumes, or contaminated air. Some embodiments provide a deployable barrier system that has a barrier retract assist system configured to assist a user in manually moving the barrier from the deployed position toward the retracted position with at least a portion of the barrier being rolled onto the barrel portion for egress past the barrier. The retract assist system can be positioned inside of the barrel portion.
