A selector mechanism includes a selector interface having a detent member. An artificial feel positioner defines a plurality of artificial feel positions that correspond to selectable positions of the selector interface. The plurality of artificial feel positions are connected via a screw channel that helically extends along the artificial feel positioner. A motor rotationally operates the artificial feel positioner to automatically operate the detent member through the screw channel to move the detent member and the selector interface to a desired position of the detent member and the selector interface.

An accelerator device includes at least one drive source, a pedal lever, and a power transmission mechanism. The pedal lever is configured to move according to a pedal depressing operation. The power transmission mechanism is configured to transmit force both in the pedal lever's closing direction and opening direction to the pedal lever by driving of the drive source.

An accelerator device includes a pedal lever, at least one drive source, a power transmission mechanism, and a locking mechanism. The pedal lever operates in response to a depressing operation. The drive source is configured to exert a reaction force as a force in a returning direction to the pedal lever. The power transmission mechanism transmits a drive force from the drive source to the pedal lever. The locking mechanism is capable of regulating the operation of the pedal lever.

A base section can operate to one side and the other side in a predetermined direction. A contact section is attached to a spring and can be in contact with the base section. A holding section holds the spring. A wall portion faces the contact section in the predetermined direction, and generates a sound which becomes a moderation feeling by a collision between the wall portion and the contact section moved by a biasing force of the spring as a contact state between the contact section and the base section changes due to an operation of the base section. The holding section regulates a position of the spring at least in a predetermined direction. A clearance between the contact section and the wall portion is substantially equal on the one side and the other side in the predetermined direction.

The invention relates to a foot pedal control unit for an ophthalmic surgery system. The unit has a base and a treadle that is configured for pivotal pitch movement and for pivotal yaw movement relative to the base for generating control signals to an ophthalmic surgery system. The unit further comprises an inlay cover that is removably placed on the treadle. Optionally, the unit comprises a locking element that is movable between a lock position wherein the treadle is locked against pivotal yaw movement and a release position wherein the treadle is enabled to perform pivotal yaw movement.

Brake adjustment dials, systems, and components adjust the brake bias in a vehicle. In one example, a brake bias adjustment dial includes an electronic display, an adjustment mechanism that transfers rotational torque to a shaft, and a rotation prevention feature that compensates the rotation of the adjustment mechanism to maintain the image displayed on the electronic display in a substantially fixed orientation with respect to a mounting.

An actuator for activating a plurality of operating functions in a technical system may include one or more of the following: a rotary knob, the rotary knob being rotatable about a rotational axis to an actuation position corresponding to a first operating function of a plurality of operating functions; a first sensor unit, where the actuation position is detectable by the first sensor unit such that a corresponding actuation position signal is sent to a control unit of the technical system causing activation of the first operating function; a second sensor unit for sending a shut-off signal to the control unit, where the technical system is set to a basic function of the plurality of operating functions upon receipt of the shut-off signal; and at least one sliding track partially encircling the rotary knob radially over an angle of less than 360.
