Joshua D. KEYES has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11668606
    Abstract: A method and system of verifying asphalt mat temperature values and location data generated by a paving machine includes identifying a location and temperature value of a threshold thermal characteristic of thermal data generated by the paving machine, and displaying the paver-generated location and temperature value of the threshold thermal characteristic on a display of the paving machine. The method further includes determining a location and temperature value of the threshold thermal characteristic by one or more external systems, and comparing the externally-determined location and temperature value to the paver-generated location and temperature value.
    Type: Grant

  • Patent number: 11408134
    Abstract: In one aspect, a method of controlling an operation of a compactor during a paving operation may include obtaining thermal image data and position data of an asphalt mat using a measuring device on a paving machine, and determining, using a controller, whether a person is on the asphalt mat based on a temperature range and the thermal image data. The method also includes determining, using the controller, a distance between the person and the compactor using the obtained position data and a position of the compactor, and generating, using the controller, a signal for reducing a speed of the compactor when the determined distance between the person and the compactor is less than a maintain speed threshold distance. In other aspects, a related system is provided for controlling a compactor during a paving operation.
