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.

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.

A novel embodiment of a drive mechanism for use in a pump, for example, of the type that would be used in a wearable drug delivery system, comprises, a cylindrically-shaped slider element configured with a channel on a circumferential surface thereof defining one or more zig-zag-shaped tracks therethrough. One or more pegs are engaged within the tracks, such that a back and forth longitudinal motion of the slider element along a radial axis of the cylinder causes movement of the pegs along one of the tracks through the channel, thus providing a movement of the pegs around the circumference of the cylinder which imparts a rotational motion to a header element disposed co-axially with the slider. The header element is in turn connected to a gear train, for example, a planetary gear box, which is coupled to the pump via a linkage or other type of mechanism.

The invention provides a cable drive device (10) including a linear drive member (12), and a cable drum (14) attached to a support bracket (30, 32) adapted to be affixed to a surface. The cable drum (14) has an axle (26) supported by the support bracket (30, 32) to allow rotation of the cable drum (14). The cable drum (14) has a cable (42) affixed at either end of said linear drive member (12) and tautly wrapped around the cable drum (14). The cable drum (14) is located between the ends of the linear drive member (12) to, in use, allow the linear drive member (12) to be guided through the bracket (30, 32) to move the linear drive member (12) longitudinally when the axle (26) is rotated.

An actuator device includes a cartwheel flexure having a central moving carriage component configured for parallel motion along an axis of the actuator device. A frame is configured to remain stationary relative to the central moving carriage component. A plurality of cross-beams flexibly support the central moving carriage from the frame, wherein the plurality of cross-beams provide flexibility for movement of the central moving carriage relative to the frame along the axis and provide rigidity in other directions.
