    Abstract: An apparatus, system, and method for determining the geographical location of a roadway mark or portion thereof not meeting roadway mark standards data. The system includes a GPS antenna; a GPS receiver responsive to the GPS antenna for determining the geographical location of the GPS antenna; and a system responsive to the GPS receiver. The system (a) determines the GPS geographical location of the roadway mark or portion thereof, (b) determines characteristic data of the roadway mark or portion thereof, (c) inputs roadway mark standards data, (d) compares the roadway characteristic data with the roadway mark standards data, and (e) determines the geographical location of the roadway mark or portion thereof based upon the comparison of the roadway characteristic and standards data.

    Abstract: A field programmable controller for controlling the components of roadway marking equipment mounted on a vehicle. The controller includes a general-purpose computer and a microcontroller for controlling and monitoring roadway marking equipment and which further maintains the operational state of the roadway marking equipment during reprogramming of the microcontroller. A wireless transceiver in communication with the internet for receiving software update data is also included. Finally, the controller has a configurable state machine responsive to the microcontroller and configured for: defining the start-up operational state of the components; maintaining a predetermined operational state of the components during the time the computer and microcontroller is being reprogrammed with software update data; and maintaining the operational state of the components for normal operation.

    Abstract: A control system for positioning a marker over a pre-existing roadway surface mark. The control system has an electromagnetic radiation source attached to the marker for producing a mark pattern on the roadway surface. An imager permits the control system to image both the pre-existing roadway surface mark and the mark pattern produced by the electromagnetic radiation source. A computer is responsive to the imager for producing an error signal based upon the location difference between (a) the image of the pre-existing roadway surface mark and (b) the image of the mark pattern produced by the electromagnetic radiation source. An actuator is responsive to the error signal for positioning the marker over the pre-existing.
