An aircraft seat module has an enclosure unit which at least partially delimits a flight passenger seating area, and has a door unit which at least in an operating state is at least configured to close a passage region to the flight passenger seating area, has a bearing device which is configured to support the door unit so as to be movable between an open position and a closed position in relation to the enclosure unit, and has a locking device which is configured to lock the door unit in the open position, wherein the locking device has at least one electrically and/or electronically actuatable actuator device, which is at least configured to be electrically and/or electronically actuated for an unlocking of the door unit.

A lever apparatus having a lever connected to a latch assembly operable to open the latch when rotated to a second position from a first position under an actuation torque. The apparatus further includes a magnet assembly with first and second magnets operably coupled to the lever apparatus. The magnet assembly is operable to generate a return torque in an opposite direction to that of the actuation torque such that the lever is returned to the first position after the actuation torque is removed from the lever.

A system for monitoring a closed state of a cover of an exposure machine includes a servo motor, a photoelectric encoder, and a controller. A shaft of the servo motor is coaxially fixedly connected to a shaft of the cover. The photoelectric encoder is provided on the servo motor, and is configured to detect an angle of rotation of the shaft of the servo motor. The controller is connected to the servo motor and the photoelectric encoder, and is configured to control rotation of the shaft of the servo motor and determine whether the cover is in the closed state according to the angle.

A method of installing a door-carriable portion (2), for a door stop (1), to be carried by a door. The door-carriable portion includes a magnet and a retaining member (7). The method includes drilling a hole in a bottom of the door; placing the magnet in the hole; and fastening the retaining member to the bottom of the door to at least partly span the opening to retain the magnet.

A securable pet door is disclosed. The securable pet door may comprise at least one door, at least one knob, one or more windows, at least one frame, and/or at least one hinge. The knob comprises a latch for secure closing. When the pet door comprises at least one hinge, the hinge(s) may be inserted into at least one hinge recess so that the door may be securely locked via at least one locking mechanism. The different elements of the securable pet door are configured to be oriented in a predetermined, securable, or customizable manner. The door is configured to open from, slide into, revolve within, or move in some other non-limiting equivalent way from or relative to a frame.

A door assembly may include a first sidelite configured to be operably coupled to a first doorjamb, a second sidelite configured to be operably coupled to a second door jamb where the first and second sidelites are disposed in a common plane and define a door opening between the first and second sidelites, a first sliding panel, a second sliding panel where the first and second sliding panels are movable from a closed position disposing the first and second sliding panels to block access through the door opening and an open position in which the first sliding panel is proximate the first sidelite and the second sliding panel is proximate the second sidelite, a first partial door panel, and a second partial door panel. The first and second sliding panels are disposed in a second plane parallel to the common plane in both the open and closed position. The first and second partial door panels are operably coupled to the first and second sidelites, respectively, via hinge assemblies. The first and second partial door panels have a closed state in which the first and second partial door panels are each disposed in the common plane blocking access through the door opening, and an open state in which the first and second partial door panels are each disposed out of the common plane.
