System for detecting the movement conditions of the leaf (2) closing a barrier, this leaf being able to occlude a delimited opening or passage and in which the leaf itself is moved by a motor (5) whose rotation shaft (R1) is associated with a motion transmission mechanism to this leaf. On said motor is present a first device for measuring the rotation of said rotation shaft (R1), and at least a second measuring device is associated with at least a second rotation shaft (R2), said second rotation shaft being connected to the first shaft by means of a reduction gear (8), whose reduction ratio is non-integer.

A locking mechanism for an opening/closing cover supported by an apparatus case in an openable and closable manner includes a rotational gear, a rack gear, a locking member and a spring member. The rotational gear rotates with an opening and closing operation of the opening/closing cover. The rack gear slides with a rotating of the rotational gear. The locking member has a hooking part facing the rack gear. The spring member pushes the hooking part toward the rack gear. The hooking part restricts a sliding of the rack gear in an opened state of the opening/closing cover.

A passage barrier includes two guide elements that cooperate such that they define a gate region, through which a person passes from an entrance region into a passage region. At least one of the guide elements includes a vertically running profile, on which a locking apparatus is arranged. The locking apparatus has a torque transmission toothing, which engages into a complementary torque reception toothing of a hollow shaft of a drive. A circular stop disc is also provided and has a toothing engagement, which is engaged with the torque transmission toothing. The stop disc has a circumferential surface with a stop lug, which protrudes radially from the stop disc circumferential surface, and cooperates with a stop element arranged on the vertically running profile such that a rotation of the stop disc is delimited by the engagement of the stop lug against the stop element.

An exemplary method involves operating a door operator coupled to a door. The door operator includes a motor operable to move the door in at least one direction and a controller operable to control the motor. The method generally involves a calibration procedure including: with the door at a first position and the door having an initial speed, initiating, by the controller, measurement of a time duration; in response to the door reaching a target speed different from the initial speed, ceasing, by the controller, measurement of the time duration; and determining, by the controller, a maximum speed based on the time duration. The method further includes performing at least one operation based upon the maximum speed.

A movable barrier operator that includes a motor, an armature shaft of the motor, and a worm screw assembled with a distal end portion of the armature shaft. The movable barrier operator further includes a worm wheel engaged with the worm screw and a rotatable drive member connected to the worm wheel. Turning of the armature shaft and worm screw mounted thereto causes turning of the worm wheel and rotatable drive member.

An actuator for motor vehicle applications, in particular for motor vehicle closing devices, comprising an electric motor, an actuating element which can be directly or indirectly acted upon via a drive train, and, arranged on a drive shaft of the electric motor, a drive wheel with an evoloid toothing, the drive train having at least one crown gear stage.

A window operator handle and cover with magnetic features that enable the handle to be retained to the cover in a folded position. The operator cover can also be attached to the operator with magnets.

The disclosure relates to a revolving door assembly (1) comprising a central column (2) and at least one door panel connected to the central column (2) and rotatably arranged around a central axis (X) of the central column (2). The revolving door assembly (1) comprises a drive unit (6) enclosed within the central column (2), the drive unit (6) comprising a motor (13) for rotating the door panel (3). According to the revolving door assembly, the motor (13) has a central through hole (H1), wherein one or more cables (C1) of a cable configuration (C) are configured to pass through the central through hole (H1).

A casement window operator includes a linear input mechanism configured to be mounted to a stationary frame of a casement window, a linear to rotary motion converter operably coupled to an output of the linear input mechanism, a gear reducer operably coupled to an output of the rotary motion converter, and a sash arm operably coupled to an output of the gear reducer to rotate in conjunction with the output of the gear reducer. The sash arm is configured to extend from the stationary frame of the casement window to a rotatable window sash of the casement window.
