Laser Light Receiver Apparatus With Automatically Adjustable Zero-Reference Point
View pageUS Patent:
7414704, Aug 19, 2008
Filed:
Jul 25, 2007
Appl. No.:
11/880972
Inventors:
Kevin R. Nau - New Carlisle OH, US
Assignee:
Apache Technologies, Inc. - Dayton OH
International Classification:
G01C 3/08
US Classification:
356 408
Abstract:
An improved laser light receiver is provided that senses a laser light beam and determines positional elevation of the laser receiver based on the position where the laser light beam impacts the light sensors of the laser receiver. The laser receiver automatically adjusts its zero-reference point when it senses a magnet that has been mounted on a clamping device that holds the housing of the laser light detector in at least two predetermined attitudes with respect to the clamping device. Thus the invention operates as a clamp-actuated “offset” on-grade mode for the laser receiver.
Distance Based Position Sensing
View pageUS Patent:
20130003037, Jan 3, 2013
Filed:
May 29, 2012
Appl. No.:
13/482130
Inventors:
Kevin R. NAU - New Carlisle OH, US
International Classification:
G01C 3/08
US Classification:
356 301
Abstract:
Systems, methods, and other embodiments associated with distance based position measurement are described. In one embodiment, an apparatus is configured to be positioned proximate a feature of interest. The apparatus includes a laser distance meter (LDM) configured to emit a laser beam and to determine first and second distances between the LDM and first and second targets. The first and second targets have known positions in three dimensions with respect to a reference plane from which the LDM is located. The apparatus also includes a trilateration unit configured to compute a two dimensional position of the LDM relative to the targets based, at least in part, on the first and second distances.
Method And Apparatus For Controlling The Slope Of A Blade On A Motorgrader
View pageUS Patent:
50782150, Jan 7, 1992
Filed:
May 29, 1990
Appl. No.:
7/530905
Inventors:
Kevin R. Nau - Tipp City OH
Assignee:
Spectra-Physics Laserplane, Inc. - Dayton OH
International Classification:
E02F 376
US Classification:
172 45
Abstract:
A method and apparatus is provided for controlling the parallel blade slope angle of a blade in order to maintain a desired cross slope during normal operation of a motorgrader regardless of whether the motorgrader is turning, the front wheels are side-tilted or the blade supporting A-frame is side-shifted. The present invention controls the cross slope angle cut by the blade of a motorgrader by substantially continuously sensing the perpendicular slope angle of the blade by means of a slope sensor and the angle of rotation of the blade relative to the direction of the travel by means of a noncontact sensor. The sensed angles are used to calculate the parallel slope angle of the blade relative to horizontal which is required to maintain a desired cross slope angle. The parallel slope angle is sensed by means of the slope sensor and controlled such that it is maintained substantially equal to the calculated parallel slope angle to thereby define the desired cross slope angle set by an operator.
All-In-One Integrated Sensing Device For Machine Control

Abstract:
An integrated sensing device with a suite of sensors assists construction machine operators in finding the correct level to dig a ditch/trench. The sensing device includes a gravity sensor to determine angles, a laser distance meter (LDM), and a laser receiver for detecting a known jobsite elevation. The sensing device is mounted to the dipper stick of an excavator; the gravity sensor detects the angle of the stick, and the laser receiver detects a laser plane of light that represents a known jobsite elevation. The LDM is aimed at another member of the machine that moves in a predetermined path as the bucket is rotated, and the distance between the LDM and the target member is used to calculate the vertical elevation of the working tool edge. A display graphically shows the operator the proper dig depth and the present position of the working tool edge.
Guidance System For Earthmoving Machinery
View pageUS Patent:
20160076228, Mar 17, 2016
Filed:

Appl. No.:
14/486463
Inventors:
- Sunnyvale CA, US
Kevin Ray Nau - New Carlisle OH, US
Kevin Ray Nau - New Carlisle OH, US
International Classification:
E02F 9/26
Abstract:
Disclosed is a guidance system that helps an earthmoving machine operator to control exactly to what elevation to dig. The system includes an electronic sensing device and a display monitor. In one embodiment, the electronic sensing device includes a distance measuring sensor (LDM), an elevation detecting sensor, an orientation sensor, and a steering mechanism for the LDM. The sensing device is mounted to an earthmoving machine, and sends signals to the display showing the machine operator where to move the digging tool for digging to the desired elevation. The various sensors in the sensing device are calibrated at the factory, so the sensing device can be mounted to an earthmoving machine and then be immediately used by that machine without needing any calibration that involves the machine itself, which is a huge advantage for the equipment operator. The measurements are made via non-contact sensors, thereby preserving the jobsite surface.
