Abstract: A computer-implemented method for automatically detecting a need for a ripping pass to be performed by a machine along a work surface is provided. The method may include monitoring one or more of machine parameters of the machine and profile parameters of the work surface, determining whether one or more predefined trigger conditions suggestive of the need for the ripping pass are met based on the machine parameters and the profile parameters, and generating a ripping pass request if one or more of the trigger conditions are satisfied.

Abstract: A system for controlling an earthmoving machine is provided. The system includes a positioning system and a controller. The controller is configured to receive the position signals from the positioning system, store the position signals in a pass history, and determine, based on pass history, an actual profile of the work surface. The controller is further configured to determine, based on the actual profile of the work surface in the pass history, existence of a first condition, the first condition exists when the actual profile has a first volume having a height above a threshold for an upper pass, and existence of a second condition, the second condition exists when the actual profile has a valley having a floor lower than the threshold for the upper pass. The controller is configured to direct the earthmoving machine to operate based on the lower pass if the first and second conditions exist.

Abstract: A system for controlling at least one machine at a work site includes a controller configured to store a map of a boundary of a work area at the work site. The controller determines a first arrival time for a first machine to arrive at the boundary and a second arrival time for a second machine to arrive at the boundary. An arrival interval is determined based upon a difference between the first arrival time and the second arrival time the relative travel speed between the first machine and the second machine is adjusted so that the machines arrive at a desired arrival interval.

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.

Abstract: A computer-implemented method for determining a cut location for a machine implement is provided. The method may include comparing a target cut volume to a projected cut volume associated with each boundary of a selected bin, designating the cut location as the boundary most closely approximating the target cut volume if both of the projected cut volumes at the boundaries are either greater than or less than the target cut volume, and designating the cut location as an average of the boundaries if the projected cut volumes at the boundaries are greater than and less than the target cut volume.

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.

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.

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.

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.
