Positioning system particularly useful for positioning agricultural implements
First Claim
1. A positioning system for positioning a movable body with respect to a reference path constituted of at least one line of subjects or a linear object, comprising:
- a signal-echo distance-measuring device to be located on the movable object and including receiver means for receiving two input signals, one input signal representing the distance of the movable object in one direction from the reference path, and the other input signal representing the distance of the movable object in the opposite direction from the reference path;
comparing means for comparing both measured distances;
a positioning device for positioning the movable object towards or away form the reference path;
and a control system controlling the positioning device in response to said comparing means for controlling the movable object to equalize said two measured distances;
said reference path being defined by a single line of objects or a single linear object, and said movable body straddling said reference path and being maintained at equal distances from the two opposite sides of said reference path.

Abstract
A positioning system for positioning a movable body, such as an agricultural implement, with respect to a reference path constituted of at least one line of objects or a linear object, such as rows of crops. The system comprises a signal-echo distance-measuring device on the movable object and including a receiver for receiving an input signal representing the distance of the movable object in one direction from the reference path, and an input signal representing the distance of the movable object in the opposite direction from the reference path. The system compares both measured distances, and positions the movable object towards or away from the reference path to equalize the two measured distances.

14. A positioning system for positioning an agricultural implement with respect to a reference path constituted of at least one row of crops, comprising:
-
a signal-echo distance-measuring device to be located on the agricultural implement and including a pair of sensors for measuring the distance of the agricultural implement in one direction or the opposite direction from the reference path; comparing means for comparing both measured distances; a positioning device, for positioning the agricultural implement towards or away from the reference path; and a control system controlling the positioning device in response to said comparing means for controlling the agricultural implement to equalize said two measured distances. - View Dependent Claims (15, 16, 17, 18, 19, 20)
