  • Patent number: 9014922
    Abstract: A system for determining a cut location at a work surface includes a position sensor and a controller. The controller stores a desired operating parameter and a final design plane of the work surface and determines an actual profile of the work surface. The controller determines a plurality of target profiles corresponding to different cut locations. The target profiles are based at least in part upon the cut location, a loading profile, slot parameters, and the actual profile of the work surface. The controller further determines an optimized target profile relative to the desired operating parameter and the optimized target profile defines an optimized cut location.

  • Patent number: 9014924
    Abstract: A system for determining material characteristics of a material of a work surface includes a position sensor and a controller. The controller stores a first estimate of the material characteristics and utilizes a planning system to determine an expected profile. The expected profile is based at least in part upon the first estimate of the material characteristics. The controller determines an actual profile of the work surface, compares the expected profile to the actual profile, and determines a second estimate of the material characteristics based at least in part upon the difference between the expected profile and the actual profile.

  • Patent number: 8948981
    Abstract: A system for determining a cut location at a work surface includes a position sensor and a controller. The controller stores a final design plane of the work surface and determines an actual profile of the work surface. A plurality of target profiles extending along a path are determined, each corresponding to a cut location. The target profiles are based at least in part upon the cut location, a loading profile, slot parameters, and the actual profile of the work surface. The controller is further configured to determine a lowest cost target profile and the lowest cost target profile defines an optimized cut location. A method is also provided.

  • Publication number: 20140180444
    Abstract: A system for modifying a path of operation of a machine includes a position sensor and a controller. The controller stores the path of operation, receives a plurality of position signals as the work implement moves material along the path of operation, and determines the position of the work surface. The controller further determines an amount of material moved based at least in part upon the position of the work surface and modifies parameters used to determine a subsequent path of operation if the amount of material moved exceeds a predetermined amount.

  • Patent number: 4274660
    Abstract: Dialkylamino-substituted 2-anilino-5'/6'-carboxyfluorans, esterified dialkylamino-substituted 2-anilino-5'/6'-carboxyfluorans and 3,3-(corresponding-substituted-diaryl)-5/6-carboxyphthalides useful as color formers, particularly in carbonless duplicating and thermal marking systems, are prepared by the interaction of 4/5-carboxy-2-(4-dialkylamino-substituted-2-hydroxybenzoyl)benzoic acids and substituted diphenylamines to produce the phthalides which are then subjected to ring closure to produce the carboxyfluorans which are esterified with alkyl halides or dialkyl sulfates.
