A drive unit for converting a rotational motion into a linear reciprocating motion includes a motor shaft extension having at least a first eccentric shaft element moving in a circle around the motor shaft's longitudinal axis and in a plane perpendicular thereto and at least one elastically deformable unit having a coupling element for coupling with a driven element. The first eccentric shaft element is coupled with the deformable unit to periodically deform the deformable unit so that a longitudinal position of the motor shaft of the coupling element of the deformable unit periodically changes. The deformable unit has a first arm section and a second arm section, each having a first end and a second end. The second end of the first arm section is connected to the first end of the second arm section, wherein the first end of the first arm section is connected to a mounting structure fixed relative to the motor. The second end of the second arm section is arranged with a distance to the first end of the first arm section in the direction of the longitudinal axis of the motor shaft.

A work device includes a work device body and a contact preventer. The work device body includes a linear motion unit having three degrees of freedom and a rotary unit having three degrees of freedom. An end effector is mounted on an output portion of the rotary unit. The contact preventer separates a working region in which the work device body is installed, from a non-working region outside the working region. The contact preventer includes: an entry allowing portion allowing an object to enter the working region therethrough; and an entry allowing portion entry detection sensor configured to detect entry of an object into the working region through the entry allowing portions.

Systems and methods for a food processing are provided. A food processing knockout assembly includes: a motor; a crank arm connected to the motor and configured to be rotated by the motor, around an axis that passes through the crank arm; a connecting arm connected to the crank arm and configured to move in a vertical direction in response to rotation of the crank arm; a beam connected to the connecting arm and configured to move in the vertical direction in response to movement of the connecting arm in the vertical direction; and at least one knockout shaft connected to the beam, at one end of the at least one knockout shaft, and configured to move in the vertical direction in response to movement of the beam in the vertical direction.

Aspects hereof relate to a stand-on terrain working vehicle having a foot-operated parking brake system. The parking brake system includes a pedal assembly having a first pedal and a second pedal, an actuator coupled to the pedal assembly, a brake configured to be actuated between a set/engaged state and a released/disengaged state, and an over-center linkage. When the first pedal of the pedal assembly is depressed, the brake is actuated to the set/engaged state, and when the second pedal of the pedal assembly is depressed, the brake is actuated to the released/disengaged state. The over-center linkage is configured to bias the brake towards one of the set/engaged state and the released/disengaged state.
