  • Publication number: 20150154247
    Abstract: A system for surface data management for a machine is provided. A first controller maintains an updated surface data and an updating time. A second controller maintains a surface data and a recording time. The second controller transmits a time request for the updating time associated with a destination location. The second controller receives the updating time associated with the destination location. The second controller is compares the updating time with the recording time, each associated with the destination location. If the updating time is more recent than the recording time, the second controller transmits a data request for the updated surface data associated with the destination location and receives the updated surface data. The second controller compares the updated surface data with the surface data, each associated with the destination location and determines a change in the surface data associated with the destination location based on the comparison.

  • Patent number: 8930043
    Abstract: A control system is disclosed for use with a plurality of mobile machines operating at a worksite having a resource. The control system may have a worksite controller configured to divide a common travel path into a plurality of segments, including at least a spot segment at the resource and a stage segment. The worksite control may further be configured to receive a first input indicative of a desire for a first of the plurality of mobile machines to leave the spot segment, and to direct the first of the plurality of mobile machines out of the spot segment based on the first input. The worksite controller may be further configured to receive first location information for the first of the plurality of mobile machines, and to direct the second of the plurality of mobile machines from the stage segment into the spot segment based on the first location information.

  • Patent number: 4428787
    Abstract: A device and method for wrapping a wrapping material to form S-shaped shields around a cable core of two side-by-side core units in which two tubes are provided for passage of the core units. A space between the tubes accepts the thickness of a central region of the wrapping material which has side portions extending away from the central region. Concave turning surfaces extend partially around the tubes and approach each other as they extend towards an outlet end of the tubes. The core units pass along the tubes and the wrapping materials passes along between the tubes while the turning surfaces progressively turn the side portions inwardly towards and around the tubes whereby the side portions are turned around the core units when these emerge from inside the tubes. In a practical arrangement, the turning surfaces are formed by the inside surface of a frusto core.
