Abstract

Embodiments of the present invention are directed to a method for performing non-contact based determination of the position of an implement. In one embodiment, the method includes using a non-contact based measurement system to determine a first measurement comprising the position of the implement relative to a mobile machine coupled with the implement, determining a second measurement comprising the geographic position of the mobile machine and determining the geographic position of the implement using the first measurement and the second measurement.

First claim

What is claimed is:

1. A system for performing non-contact based determination of a position of an implement relative to a mobile machine, the system comprising:
an emitter coupled to the implement, wherein the emitter is configured to generate a one-way signal and transmit the one-way signal; and
a distance measuring component, comprising:
a detector coupled with a particular part of the mobile machine, wherein the detector is configured to receive the one-way signal generated by the emitter, wherein the distance measuring component is configured to determine the distance between the implement and the particular part of the mobile machine based on the one-way signal received by the detector, and wherein the distance measuring component is configured to determine the position of the implement relative to the mobile machine based on the determined distance.

2. The system of claim 1 wherein the mobile machine is selected from the group consisting of a bulldozer, a motor grader, an excavator, a skid-steer loader, a scraper, a trencher, a trimmer, a tractor with an attachment, a paver, and a slip form concrete machine.

3. The system of claim 1 wherein the distance measuring component comprises an image recognition apparatus.

4. The system of claim 1 wherein the distance measuring component comprises a light-based measurement apparatus.

5. The system of claim 4 wherein the light-based measurement apparatus is configured to receive a beam of light in the visible spectrum and determine a light-based measurement based on the beam of light.

6. The system of claim 4 wherein the light-based measurement apparatus is configured to receive a beam of light in the non-visible spectrum and determine a light-based measurement based on the beam of light.

7. The system of claim 1 wherein the distance measuring component comprises a sound-based measurement apparatus.

8. The system of claim 1 wherein the distance measuring component determines a difference in an angle between the implement and the mobile machine when the implement is moved from a first position to a second position.

9. The system of claim 1 wherein the distance measuring component determines a difference in the distance between the implement and the mobile machine when the implement is moved from a first position to a second position.

10. A system for determining the position of an implement comprising:
a non-contact based sensor measurement system which does not require the use of a mast configured for determining a position of the implement relative to a mobile machine coupled with the implement, the non-contact based measurement system comprising:
an emitter coupled to the implement, wherein the emitter is configured to generate a one-way signal and transmit the one-way signal; and
a distance measuring component, comprising:
a detector coupled with a particular part of the mobile machine wherein the detector is configured to receive the one-way signal generated by the emitter, wherein the distance measuring component is configured to determine the distance between the implement and the particular part of the mobile machine based on the one-way signal received by the detector, and wherein the distance measuring component is configured to determine the position of the implement relative to the mobile machine based on the determined distance.

11. The system of claim 10 wherein the mobile machine is selected from the group consisting of a bulldozer, a motor grader, an excavator, a skid-steer loader, a scraper, a trencher, a trimmer, a tractor with an attachment, a paver, and a slip form concrete machine.

12. The system of claim 10 wherein the distance measuring component comprises an image recognition apparatus.

13. The system of claim 12 wherein the image recognition apparatus determines a location of a visual indicator proximate to the implement.

14. The system of claim 10 wherein the distance measuring component apparatus comprises a light-based measurement apparatus.

15. The system of claim 14 wherein the light-based measurement apparatus is configured to receive a beam of light in the visible spectrum and determines a light-based measurement based on the beam of light.

16. The system of claim 14 wherein the light-based measurement apparatus is configured to receive a beam of light in the non-visible spectrum and determine a light-based measurement based on the beam of light.

17. The system of claim 10 wherein the distance measuring component comprises a sound-based measurement apparatus.

18. The system of claim 10 wherein the distance measuring component determines a difference in an angle between the implement and the mobile machine when the implement is moved from a first position to a second position.

19. The system of claim 10 wherein the non-contact based measurement system determines a difference in a distance between the implement and the mobile machine when the implement is moved from a first position to a second position.
