A movable barrier operator is provided that includes a motor coupled to a movable barrier to move the movable barrier, a computing device which controls movement of the motor, a manual drive coupled to the movable barrier to move the movable barrier, a ring coupled to move with the manual drive, and a sensor that senses and communicates rotation of the ring to the computing device. In response to receiving the sensed rotation of the ring, the computing device prevents operation of the motor to move the movable barrier.

Sliding operator assemblies and associated fenestration units, systems, and methods of use and assembly are described. Some such sliding operator assemblies transition a first, linear actuation force along a first axis (e.g., vertical) to a second actuation force along a second axis (e.g., horizontal) to cause a drive mechanism to impart opening and closing forces, respectively, on the sash. Some designs relate to belt-, twisted ribbon-, or band-drive sliding operator assemblies.

A ramp door closure apparatus is provided for recreational vehicles, having a recessed linear actuator both draw a cable from a mounting bracket on the ramp door adjacent to the RV opening, to raise and lower the ramp door, and then cam a locking pin fixed to the ramp door into a seal tight position after the ramp door is raised. Upon release of the locking pin from the cam when opening the door, an initial push is provided to facilitate downward rotation of the ramp door. The linear actuator is selectively detachable from the cable so as to allow manual raising and lowering of the ramp door from within the RV, by means of releasable pins accessed in the mounting structure.

Motorized actuators for pivoting fenestration units that include both lock and open/close actuation, are addressed. Such actuators, and associated fenestration systems and methods, may achieve a variety of potential advantages, including egress functionality, ease of operation, active position control, aesthetically pleasing features (e.g., minimal design impact), intuitive controls, and others.

A panel device (10), particularly a roof light for a recreational vehicle, comprises an at least substantially polygonal frame (11, 12) which surrounds an opening (15). A window (20) is connected to the frame for pivoting about a pivot axis and comprises a panel (21) which extends over the opening. Provided between the frame and the window is a stay device (50) which is manipulable between a first position, in which the window is forced into a flat state and closes the opening, and at least one second position in which the window is raised by the stay device and leaves the opening at least partially clear. The stay device comprises a stay (51, 52) which extends movably from an elongate guide (61, 62) at a first outer end and is connected pivotally to the window at an opposite, second outer end. The stay (51, 52) is adjustable in the guide and is coupled to an actuator (78) via a flexible transmission (71 . . . 83). The transmission comprises at least one tension-resistant pull member (71-73) which is coupled to the stay (51, 52) and which is movable in an axially at least substantially rigid yet flexible sleeve (81-83), a first outer end of which is fixed to or close to the stay (51, 52) and a second outer end of which is attached to or close to the actuator (78).
