Abstract: The present invention discloses a method and apparatus for electronically confining an animal within one or more selected spaces within a selected area. Current pulses are directed around conducting perimeters surrounding the selected spaces. The animal to be confined is provided with a collar unit, which includes a sensor adapted to sense whether the animal approaches a conducting perimeter from inside the selected space or outside the selected space, and a correction unit adapted to provide correction to the animal in response to a sensor output. The portable unit reports to a central controller which selects a correction strategy, such as level of correction to be applied to the animal approaching the perimeter. The controller provides warnings to the user, including warnings for when the animal passes out of bounds, when the battery in the collar unit goes low and when the animal stays in a correction zone for too long.

Abstract: The present invention discloses a method and apparatus for electronically controlling the movement of one or more animals relative to a selected area. The selected area may be an exclusion area into which an animal is deterred from entering, or may be a confinement area from which the animal is deterred from leaving. The animal is provided with a collar unit, which includes a sensor adapted to sense the strength of electromagnetic signals generated by a generator located in the selected area, and a correction unit adapted to provide correction to the animal in response to a sensor output. The portable unit may report to a central controller which selects a correction strategy, such as level of correction to be applied to the animal approaching the perimeter of the selected area. The controller provides warnings to the user, including warnings for when the battery in the collar unit goes low and when the animal stays in a correction zone for too long.
