    Abstract: In one example, a fluid spraying device includes a chassis, a plurality of wheels connected to the chassis, a spray tip assembly connected to the chassis, and a hopper mounted on the chassis. The hopper is in fluid communication with the spray tip assembly and is configured to be oriented in an upright draining position for draining fluid from the hopper. The hopper includes a bottom side, a top side opposite the bottom side and including an aperture configured to receive and drain the fluid, and a side wall extending at an obtuse angle away from the bottom side to the top side adjacent the aperture to facilitate draining of fluid when the hopper is in the upright draining position.

    Abstract: A bead flow sensor module includes a housing, a beam, and a sensor. The beam extends into a flow channel of the housing through which a flow of beads and compressed air flows. The sensor outputs a signal indicative of bead impacts on the beam. A system incorporating the bead flow sensor module includes a compressed air source, a bead hopper, and a bead dispenser. The compressed air source delivers a flow of compressed air to the bead hopper. A flow of beads carried by the compressed air discharges from the bead hopper along a flow pathway connecting the bead hopper to the bead dispenser. The bead flow sensor module positioned along the flow pathway outputs the signal from which a bead flow volume through the bead dispenser is determined.

    Abstract: A battery powered driver for propelling a wheeled ground surface modifying machine includes at least one wheel contacting a ground surface, a battery powered electric motor, control circuitry configured to manage delivery of electrical battery power to the electric motor to control a sped of the driver, at least one pedal attached to a pedal axle and tiltable in each of a forward and rearward direction with respect to the pedal axle, and at least one pedal tilt sensor configured to output one or more signals to the control circuitry indicating a degree of tilt of the at least one pedal. The control circuitry is configured to control the electric motor to accelerate the driver forward based on the one or more signals indicating a forward tilt of the at least one pedal, the electrical battery power delivered to the electric motor for forward acceleration proportional to a degree of forward tilt of the at least one pedal, and to control the electric motor to accelerate the driver rearward based on the one or more signals indicating a rearward tilt of at least one pedal, the electrical battery power delivered to the electric motor for rearward acceleration proportional to a degree of rearward tilt of the at least one pedal.
