Patent number: 11261571Abstract: 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.Type: GrantFiled: May 22, 2019Date of Patent: March 1, 2022Assignee: LIMNTECH LLCInventors: Douglas D. Dolinar, William R. Haller

Patent number: 10843881Abstract: A bulk loader system is disclosed that may include a conveyor unit in connection with a fuel-powered engine powering a hydraulic motor. The hydraulic motor may be used to operate the conveyor unit. The system may be configured to function while being mounted on a bed of a truck or be operated as a stand-alone unit. The unit may be sized such that an operator can stand on the deck of the truck along with the unit. The fuel-hydraulic powered motor can enable the conveyor unit to operate at variable speeds. The conveyor unit can be adjustable to facilitate controlling the direction of the material being transported via the conveyor. Some embodiments can include operating the hydraulics of the motor from the Power Take-Off (“PTO”) of the truck. Some embodiments can facilitate operation of the system in a hot or other harsh environment.Type: GrantFiled: January 24, 2020Date of Patent: November 24, 2020Assignee: Ennis-Flint, Inc.Inventors: Christopher Davies, Kevin Goforth, Douglas D.

Patent number: 9784843Abstract: An apparatus for locating, inspecting, or placing marks on a roadway. The apparatus includes a GPS-based machine vision locator for sampling discrete geographical location data of a pre-existing roadway mark evident on the roadway. A computer may determine a continuous smooth geographical location function fitted to the sampled geographical location data. A marker is responsive to the GPS-based locator and geographical location function for replicating automatically the pre-existing roadway mark onto the roadway. The apparatus is typically part of a moving vehicle. A related method is disclosed for locating, inspecting, and placing marks on a resurfaced roadway. A similar apparatus can be used to guide a vehicle having a snow plow along a snow-covered roadway, or a paving machine along an unpaved roadway surface.Type: GrantFiled: March 28, 2016Date of Patent: October 10, 2017Assignee: Limn Tech LLCInventors: Douglas D.
