Various embodiments include a transmission element for a spring return of an actuating drive comprising: a toothed wheel element with teeth at least in sections; and a locking element including a locking section for locking engagement in the teeth of the toothed wheel element to prevent a rotation of the toothed wheel element in a return direction. The locking element includes a safety element mechanically operatively connected to the locking section and elastically deformable in order to release the locking of the toothed wheel element by elastic deformation of the safety element at a torque of the toothed wheel element in the return direction greater than a safety torque limit.

The object of the present invention is a drive unit for a motor vehicle component with an electromotor (5) and a rotatable output element (7). Furthermore, a blocking element (9), which can be acted on by an actuator (10), is provided for interacting with a protrusion (15) on the output element (7). According to the invention, the protrusion (15) detaches the blocking element (9) from a stop (17) at the start of a rotational movement of the output element (7). Thus, the blocking element (9) is transferred into a blocking position with the aid of the actuator (10) in which the blocking element (9) blocks a rotation of the output element (7) beyond a specified point.

Controlling a movement of an aircraft. A computer system detects a position of a group of integrated control levers for the aircraft. The computer system controls a forward thrust, a drag, and a reverse thrust generated by the aircraft based on the position of the group of integrated control levers.

A manipulation device has a manipulation body rotationally operated by the manipulator, a support body rotatably supporting the manipulation body, and a rotational load imparting mechanism. The rotational load imparting mechanism has a movable member engaged with the rotational axis of the manipulation body, a magnetism generating mechanism facing the movable member with a gap intervening, and a magnetic viscous fluid, its viscosity changing according to the strength of a magnetic field. The magnetism generating mechanism has a coil generating a magnetic field and a first yoke provided so as to enclose the coil. The first yoke has a first opposing part and second opposing part, which are separated by slits, on a side facing the movable member. The magnetic viscous fluid is filled in the gap, which is between the first opposing part and the movable member and between the second opposing part and the movable member.

A redundant mechanical control system incorporates a jam override subsystem to enable a breakout or break-away feature of the redundant mechanical control system. The jam override subsystem includes a spring and detent system to apply an axial force to a portion of an interconnect. The interconnect mechanically links a first portion of the redundant mechanical control system with a second portion. When a failure occurs, rendering inoperable the first portion or the second portion of the redundant mechanical control system, the axial force of the spring and detent system is overridden by a compression or extension force of the operable portion of the redundant mechanical control system.

A manipulation device has a manipulation body operated by the manipulator in a manipulation direction, a support body freely supporting the operation of the manipulation body, and a movable load imparting mechanism imparting a load to the manipulation body. The movable load imparting mechanism has a movable member engaged with the movable axis of the manipulation body, a magnetism generating mechanism having a coil that generates a magnetic field and a first yoke provided so as to enclose the coil, and a magnetic viscous fluid, its viscosity changing according to the strength of a magnetic field. The magnetic viscous fluid is filled in a first gap between the first yoke and the movable member. In the gap, a first buffering layer not harder than the movable member is provided on at least one of the opposing plane of the first yoke and the opposing plane of the movable member.
