Claim Text:
1. A ground marking system, comprising: a position signal receiver configured to receive a position signal and generate current position information based on the position signal; a paint supply configured to discharge paint onto ground beneath the paint supply; a first actuator operatively connected to the paint supply for linearly moving the paint supply in both of a first direction and a second direction opposite the first direction; a second actuator operatively connected to the paint supply for controlling the discharge of paint from the paint supply; a memory device storing predetermined positional data; and a processor in communication with the position signal receiver and the memory device, wherein the processor is configured to control linear movements of the first actuator based on the current position information received from the position signal receiver and the predetermined positional data stored in the memory device and thereby adjust a position of the paint supply, wherein: the ground marking system is mounted to a vehicle, the first actuator comprises a double acting hydraulic cylinder having an extensible and retractable rod, and the first actuator comprises a valve for controlling operations of the double acting hydraulic cylinder, the processor is operatively connected to the valve to control operations of the valve based on the current position information received from the position signal receiver and the predetermined positional data stored in the memory device, and the ground marking system further comprises a movable frame that is attached to the rod of the actuator and that includes a paint supply holder for mounting the paint supply such that the movable frame moves with the paint supply in both of the first direction and the second direction.
