Disclosed is a throttle quadrant arrangement having a throttle lever which is independently mechanically connected to different Rotary Variable Differential Transformers (RVDTs). A friction lever selectively creates and releases friction from the throttle lever to enable it to be selectively positioned. The system is configured such that the mechanical connections existing between the throttle lever and the RVDTs are shielded from the friction created by the friction lever.

An airplane rudder and brake pedal assembly includes a rudder arm assembly having one rudder arm with first upper and lower arm portions, and another rudder arm with second upper and lower arm portions. The rudder arm assembly is assembled to a beam at an intersection of the first upper and lower arm portions, and an intersection of the second upper and lower arm portions. The first and second rudder arms are configured to rotate about the beam at the intersection. The rotation of the first and second rudder arms is configured to adjust control surfaces that control a yaw axis of the airplane. A brake pedal is attached to the first and second lower arm portions. Rotation of the brake pedal brakes the airplane. A rotary sensor is assembled to the brake pedal and the lower arm portion, and configured to determine an extent of the brake pedal rotation.

A steering bar for a lever-controlled vehicle provides for single hand operation of the lever-controlled vehicle. For example, the steering bar couples to the control levers for a zero-turn mower, providing safer, easier operation of the mower and making the mower handicap accessible. The steering bar can easily be installed on any dual steering zero turn mower. Steering is easier because turning it controlled by rotating the steering bar either right or left, with control of forward and reverse movements by pushing or pulling the bar. Speed, turning direction, or motion forward or reverse are all controlled by a single bar with a single hand. The steering bar is coupled with a selectively extensible control shaft to accommodate for the differing displacement length between the control levers during turning movements. The steering bar is coupled with the control levers with a ball and socket joint.

A speed regulating hand brake mechanism and method for speed regulation of the speed regulating hand brake mechanism is disclosed. The mechanism includes: a housing, wherein an installation cavity is defined inside the housing; a speed regulating button is hinged to the side wall of the housing; an installation cavity is internally provided with the driving part hinged to the speed regulating button; the rack is hinged to the driving part and can slide along the inner wall of the installation cavity in a horizontal direction after receiving the pressing force transmitted from the speed regulating button; the encoder is fixed on a first fixing plate in the installation cavity, the rack drives a gear arranged at the top of the encoder to rotate, and changes the code value output by the encoder; the elastic end of the return piece is located inside the speed regulating button.

A system may include a first control component comprising an input device configured to control an operation of a display device of a machine. The system may further include a second control component. The first control component (or the second control component) may be configured to control a movement of an implement of the machine. The second control component (or the first control component) may be configured to control a movement of the machine.

The present concepts relate to haptic controllers. In one example the haptic controller can include first and second capstans rotationally secured to a base and an energy storage mechanism connected between the first and second capstans. The example haptic controller can also include a user engagement assembly secured to the first capstan and a controller configured to control rotational forces imparted on the user engagement assembly by controlling rotational friction experienced by the first and second capstans.
