A method and apparatus to confine and constrain an animal or human subject to
a
specific area has the capability to change the borders of the restraint area remotely
to maximize an area's utility. A collar or support is placed on the subject; the
collar carries an electronic module to receive and send signals and to activate
a restraining or feedback mechanism. In its simplest form, the collar receives
and transmits Global Positioning System (GPS) data to be matched against a preset
group of boundary coordinates. The system of the present invention utilizes GPS
location technology to define the boundary. When the input matches the boundary
coordinates set into the receiver, an impulse is delivered to the subject or wearer.
This impulse becomes increasingly severe as the wearer moves farther away from
the boundary point. Upon return to the boundary location the impulse ceases and,
as long as the wearer stays within the boundaries, no further impulse is imparted.
Terrain of the designated area is not a factor in the operation of the system since
it can be programmed for use anywhere. The coordinates of the boundaries can either
be preset or remotely changed to redefine the permitted areas.
