Device and method for containing and tracking a subject using satellite positioning data
DCFirst Claim
1. A device to be disposed on a subject for determining whether the subject is inside or outside of a containment zone defined by a containment perimeter, the device comprising:
- A positioning unit for generating position data corresponding to the position of the subject;
the position data including satellite positioning data; and
A processor unit, in communication with the positioning unit, configured to;
Receive data from a memory representing a plurality of line segments forming the containment perimeter;
Obtain from the positioning unit the position data corresponding to the position of the subject;
Mathematically cast a ray from the position of the subject toward a line segment of the plurality of line segments representing the containment perimeter;
Mathematically determine the number of line segments of the plurality of line segments that are intersected by the ray; and
Determine, from the number of line segments of the plurality of line segments intersected by the ray, whether the subject is inside the containment zone or outside of the containment zone.

Abstract
A device to be disposed on a subject for determining whether the subject is inside or outside of a containment zone defined by a containment perimeter. There is a positioning unit for generating position data, including satellite positioning data, of the subject; the position data. There is a processor unit, in communication with the positioning unit, configured to receive data from a memory representing a plurality of line segments forming the containment perimeter and obtain the position data of the subject. The processor casts a ray from the position of the subject toward a line segment of the containment perimeter and determines the number of line segments that are intersected by the ray. The processor determines from number of line segments intersected by the ray, if the subject is inside the containment zone or outside of the containment zone.
