  • Universal optical adapter for a three dimensional earthgrading system
    Patent number: 6966387
    Abstract: A universal optical adapter assembly for use with a planar automatic grading system for an earth-moving vehicle having a grading implement that defines a graded surface. The automatic grading system includes an energy beam receiver mounted on the earth-moving vehicle and operable for detecting the height at which a datum energy beam strikes the receiver along a detection portion thereof. A control device is operably coupled to the energy beam receiver and the grading implement to control the elevation of the grading implement in response to the position at which the datum energy beam strikes the detection portion of energy beam receiver. The optical interface adapter assembly includes an optical interface apparatus having an energy source emitting one or more implement controlling energy beams strategically onto selected positions of the detection portion the energy beam receiver to control the elevation of the grading implement.
