    Abstract: A chain operator for a window, and particularly a skylight window, having a casing with a chain storage area from which a chain can be advanced for opening of the window. The casing is constructed for mounting of different types of drive mechanism for a chain drive sprocket within the casing. A unitary liner is fitted within the casing to provide a reduced friction mounting for the drive sprocket and a reduced friction guide for the chain, with the liner being positioned in high load and high wear areas to result in smooth and quiet long-life operation. The chain operator has a chain composed of solid links pivotally interconnected by U-shaped links and interrelated in a manner to readily move between straight and curved configurations and operate under relatively heavy load.

    Abstract: The disclosure relates to a method at a control device (100) for controlling an overhead door operator system, the overhead door operator system (1) being configured for opening and closing an opening (2), and comprising a door frame (3) comprising a first frame section (4) at a first side (7) of the opening (2) and a second frame section (6) at a second side (5) of the opening (2). The operator system further comprises a door (8) arranged to be moved between an open and closed (C) position, the door (8) being movably connected to the door frame (3) and a drive unit (10) mounted on the door (8), the drive unit (10) comprising at least one motor (11) arranged to move the door (8) from the closed position (C) to the open position (O). An elongated transmission member (19) extends along the first side (7) of the opening (2) and the first frame section (4). The drive unit (10) further comprises a driven transmission member (18) in driving connection with the motor (11). The method comprises the steps of: detecting door movement; determining if detected door movement relates to unexpected door movement; and, if so, taking action so as to prevent more extensive damages. The disclosure further relates to an overhead door operator system for opening and closing an opening.

    Abstract: A flex-drive actuator for a satellite boom hinge or other hinge applications. Using a motor-driven cog and a unique drive chain, the hinge can be reversibly driven between open and closed positions, thereby deploying or stowing the boom and attached payload. The chain includes links designed so that, when bent in one direction, the chain pre-buckles into a rigid circular arc form that matches the deployment path of the hinge. This pre-buckling essentially converts the chain into a rigid gear segment that can carry a moment to actuate the hinge. As the cog retracts the chain and the hinge closes, the circular shape of the chain de-buckles on the free side of the cog, where the chain can be stored as a straight section inside of a boom tube or folded into a magazine. The flex-drive actuator can accommodate any desired actuation angle by addition of links to the chain.

    Abstract translation: 用于卫星吊杆铰链或其他铰链应用的柔性驱动致动器。 使用马达驱动的齿轮和独特的驱动链，铰链可以在打开和关闭位置之间可逆地驱动，从而部署或收起吊杆和附加的有效载荷。 链条包括设计成使得当沿一个方向弯曲时链条预弯曲成与铰链的展开路径匹配的刚性圆弧形状。 该预弯曲基本上将链条转换成刚性齿轮段，该刚性齿轮段可以承载一段时间来致动铰链。 当齿轮缩回链条并且铰链关闭时，链条的圆形形状在齿轮的自由侧处脱扣，链条可以作为直立部分存储在悬臂管内部或折叠成料仓。 柔性驱动致动器可以通过添加到链条的链接来适应任何期望的致动角度。
