A construction machine that frequently changes between a forward and reverse direction of movement includes a system and method for operating the machine such that rotation of the operator seat can change the direction and speed of the machine's movement to minimize disorientation by the operator. The machine can be changed from moving in the forward direction to moving in the reverse direction, without changing the position of a propel lever or joystick that is used to control the direction and speed of the machine's movement. Rotation of the seat can be used to proportionally reduce the speed of the machine as the machine nears a threshold for changing direction. The joystick can be a dual axis lever that can move along a longitudinal axis and a lateral axis. The direction of movement and speed of the machine can depend on a combination of the joystick position and seat position.

A work vehicle includes an operating lever configured to operate a work implement, an actuator configured to move the operating lever, and a control section configured to control the actuator to move the operating lever to a retreat position outside an operation range of the operating lever.

The present disclosure relates to a virtual reality control device. The virtual reality control device comprises a pedestal, an upper body supporting element connected to an upper part of the pedestal, a lower body supporting element connected to a lower part of the pedestal, a central shaft whose one end is connected to the pedestal and another end is connected to a central portion of the upper body supporting element, and one or more encoders whose ends are connected to the pedestal and the other ends are connected to the upper body supporting element. The upper body supporting element makes a movement around the central shaft on the basis of a movement of the user, and the one or more encoders detect at least one of a linear displacement, a rotation angular displacement, and a speed depending on the movement of the upper body supporting element to generate first signals.

Implementations relate to a master control device. In some implementations, a master control device includes a thumb grip member including a thumb grip receptive to a thumb of a hand of a user. The master control device includes a finger grip member coupled to the thumb grip member at a proximal end of the master control device and extending toward a distal end of the master control device, where the finger grip member includes a finger grip receptive to multiple fingers of the hand. The thumb grip member and finger grip member are movable in a pinching configuration with respect to each other. The master control device includes a sensor coupled to at least one of the thumb grip member or finger grip member to sense relative positions of the thumb grip member and finger grip member with respect to each other in the pinching configuration.

A mouth activated controller can be useful for operating equipment such as welders, drills and other equipment which may have traditionally utilized other controllers in the past, like foot controllers, etc. The mouth controller could operate in a live mode such as based on the pressure applied to a mouth pad, such as through teeth, or a step mode whereby a number of bites controls operation of the equipment for at least some embodiments.

A bicycle trailer brake includes an actuator forming a lever to actuate a brake. The actuator includes a mounting structure to couple the actuator to a bicycle or bicycle trailer and an input interface to receive an input force from a user. Upon attachment of the mounting structure to a bicycle or bicycle trailer, the input interface is positioned in a position behind and above a bicycle seat of a bicycle.
