  • Patent number: 11273752
    Abstract: An illumination control system for a mobile machine that operates in coordination with other mobile machines is configured to adjust an illumination lamp disposed on the mobile machine and directed in a travel direction of the machine. The illumination control system includes a positioning/location device that can determine a proximity distance between the mobile machine and a second mobile machine approaching in the travel direction. The illumination control system also includes an electronic controller configured to adjust the illumination device based on the proximity distance as determined. The illumination control system may find particular usefulness in paving and/or milling operations.

  • Patent number: 8944227
    Abstract: A pantograph assembly configured to transfer electrical power from an overhead conductor to a machine. The pantograph assembly includes a pantograph support detachably connected to the machine, an articulated assembly, a pan rail and a carbon brush. The pantograph support includes a first link, and a second link hingedly connected to the first link. The first link is connected to the pantograph support. The pan rail is supported by the second link of the articulated assembly. The carbon brush is supported by the pan rail along a longitudinal axis of the pan rail. The pantograph assembly further includes an end horn having a bridge portion connected to the carbon brush. The bridge portion is configured to transfer the overhead conductor between the end horn and the carbon brush.
