An example method includes storing marking data to specify at least one selected marking to apply at a target location along a vehicle path of travel, the marking data including a machine-readable description and a marking reference coordinate frame for the selected marking. The method also includes generating task plan data to apply the selected marking based on the marking data and at least one parameter of an application tool. The method also includes determining a location and orientation of the application tool with respect to the vehicle path of travel based on location data representing a current location of a vehicle carrying the application tool. The method also includes computing a joint-space trajectory to enable the application tool to apply the selected marking at the target location based on the task plan data and the determined location of the application tool.

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.

A line marking device (1) comprising a cart (2) with at least one steerable wheel (3) and at least two moving elements (4, 5). The steerable wheel (3) is rotatable around its axle (13) and pivotable such that the cart (2) is steered in a desired direction. The line marking device (1) comprises a GNSS receiver (7) or a robotic total station mounted on the cart (2). The line marking device (1) also comprises at least one spray nozzle (8), for marking a line, which is mounted on the cart and directed towards the ground below the line marking device (1). The device (1) comprises an interface mounted on the cart for a comparator to compare a detected location by the GNSS receiver (7) to a predetermined pattern. The cart (2) may comprise a motor (14) which is adapted to pivot the steerable wheel (3) towards an intended movement.

A holder (1) for fixing a cylindrical spray can (2) is disclosed. The holder (1) comprises a holding unit (3) for fixing the spray can (2) with a first mechanical interface (4) for connecting a GNSS receiver (5) or a prism to the holding unit (3). The holding unit (3) is adapted to hold the spray can (2) such that the GNSS receiver (5) or the prism and the spray can (2) are arranged coaxially with respect to each other. The holding unit (3) comprises a second mechanical interface (6) for releasably connecting the holder (1) to a frame (7) of a surveying cart (8).

The invention involves a low speed control system and method for automatically regulating the speed of work vehicles or equipment and, more particularly, vehicles that apply, remove or modify roadways or road markings. The system includes a controller, a speed display, at least one rotary encoder or the like, and one or more Eddy current or mechanical brakes for inhibiting motion of the vehicle at the operator's control. The brakes may be pneumatic, spring operated, Eddy current, or hydraulic that are controlled in response to feedback from the at least one rotary encoder for compliance with the preset speed on the speed display. In another embodiment, a throttle control is also provided.

A paint-striping guidance system including an outrigger attachable to a paint-striping machine, a light-emitting device carried by the outrigger, and a mounting assembly configured to provide an adjustable connection between the light-emitting device and the outrigger. The light-emitting device is configured to form a planar light region having a vertical orientation. The mounting assembly includes an adjustment mechanism operable to move the light-emitting device relative to the paint-striping machine and thereby change a yaw angle of the planar light region.

A joint form is positioned in a damaged expansion joint to allow both sides of the joint to be repaired at the same time. The joint form remains as a permanent part of the repair, which avoids the time consuming conventional process of removing temporary forms, cleaning the repaired surfaces, and inserting an elastomeric seal into the expansion joint. Type-0 joint forms include a block-seal laminate including a foam block layer (e.g., closed-cell polyethylene) laminated to an upper elastomeric seal layer (e.g., closed-cell neoprene) without a stiffener board. Type-1 joint forms include a block-seal laminate with a stiffener board (e.g., fiberglass reinforced plastic or FRP) adhered to one side of the block-seal laminate. Type-2 joint forms include a pair of block-seal laminate panels on either side of a central stiffener board bonded to one side laminated to an upper seal layer. Joint forms may also be utilized to seal undamaged expansion joints.
