Implement control system for locating a surface interface and removing a layer of material
First Claim
1. An apparatus coupled to a work machine to assist the work machine in removing a first layer of material from a second layer of material, the work machine having a frame, comprising:
- a work implement having a cutting portion and being elevationally movably connected to the work machine, said cutting portion extending in a direction transverse to a longitudinal axis of the work machine;
electromagnetic means, mounted to the work machine, for delivering electromagnetic radiation to penetrate the first layer of material, receiving a reflection of said delivered electromagnetic radiation from said second layer of material, and generating a responsive first signal;
interface detecting means for receiving said first signal, determining the distance between said electromagnetic means and the second layer of material and responsively producing a distance signal; and
implement control means for receiving said distance signal and responsively controlling the position of said work implement relative to said frame.

Abstract
An apparatus coupled to a work machine for assisting the work machine in removing a first layer of material from a second layer of material is provided. The work machine includes a work implement with a cutting portion. The work implement is elevationally movably connected to the work machine. The cutting portion extends in a direction transverse the longitudinal axis of the work machine. An electromagnetic unit, connected to the work machine, delivers electromagnetic radiation towards the surface, receives a reflection of the delivered electromagnetic radiation, and delivers a responsive first signal. The electromagnetic radiation penetrates the first layer of material and reflects off of the second layer of material. A controller receives the first signal, determines the distance between the electromagnetic unit and the second layer of material and responsively produces a distance signal. An implement controller receives the distance signal and responsively actuates the work implement relative to the frame.
