Abstract
A pet containment system uses a transmitter for transmitting a series of electromagnetic signals, and a receiver removably attached to the pet for receiving the series of electromagnetic signals from the transmitter. The transmitter includes means for modulating the electromagnetic signals, means for transmitting the resulting non-random patterns of electromagnetic energy, and at least one transmitting antenna. The receiver includes at least one receiving antenna, means for comparing the signal level of the received electromagnetic signals from said transmitter with a predetermined level and for producing an electronic indication of a loss of signal, means for comparing the phase of the received electromagnetic signals from said transmitter with a reference phase and for producing an electronic indication of a loss of phase, means for producing a warning stimulus to the pet, and means for producing a control stimulus to the pet. The present invention also provides a method for producing an area for the containment of a pet.
