Method and appartus for training and for constraining a subject to a specific area

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.
