Abstract
A system is employed for defining a position (location) of a receiving element inside an area surrounded by a wire loop, along the perimeter (a perimeter wire loop), of a work area or other bounded area. In particular, the system can determine whether the receiver is inside or outside the loop, and evaluate its distance from the perimeter wire.

16. A method for determining the location of a receiver, comprising:
-
providing a first loop including a first portion and a second portion;
providing a second loop including the second portion and a third portion;
providing a signal over a first loop and providing the signal over a second loop at a predetermined providing interval, the signal providing such that at least the first portion is always receiving the provided signal, the second portion and the third portion are receiving the provided signal in accordance with the predetermined providing interval;
receiving the signal;
converting the signal to pulses;
counting the pulses for a predetermined receiving interval; and
analyzing the counted pulses for the predetermined receiving interval against predetermined pulse counts for the predetermined receiving interval in accordance with the predetermined providing interval to determine the location of the receiver. - View Dependent Claims (17, 18, 19, 20)
