Wireless pet containment system

A method for producing an area for the containment of a pet, the method comprising:

• (a) transmitting a series of electromagnetic signals from a transmitter, further including:
• (1) generating the electromagnetic signals, and
• (2) transmitting the electromagnetic signals;
• (b) attaching a releasable electromagnetic energy receiver to a pet;
• (c) receiving the series of electromagnetic signals with the releasable electromagnetic energy receiver;
• (d) comparing the phase of the received electromagnetic signals received with the,releasable electromagnetic energy receiver with a predetermined phase and producing an electronic indication of a loss of phase, wherein if the phase of the received electromagnetic signals with the releasable electromagnetic energy receiver is not substantially in phase with the predetermined phase then the electronic indication of a loss of phase is produced;
• (e) producing no control stimulus to the pet when there is no electronic indication of a loss of phase;
• (f) producing a control stimulus to the pet when there is an electronic indication of a loss of phase.

A pet containment system comprising:

• (a) a transmitter for transmitting a series of electromagnetic signals, wherein said transmitter further includes:
• (1) means for generating the electromagnetic signals,
• (2) means for transmitting the non-random patterns of electromagnetic signals, and
• (3) at least one transmitting antenna;
• and
• (b) a receiver removably attached to the pet, said receiver for receiving the series of electromagnetic signals from said transmitter, wherein said receiver further includes:
• (1) at least one receiving antenna,
• (2) 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 level, wherein if the signal level of the received electromagnetic signals from said transmitter is less than the predetermined level then the electronic indication of a loss of signal level is produced,
• (3) means for determining the substantial presence of the received electromagnetic signals from said transmitter and for producing an electronic indication of a loss of received signal, wherein if the received electromagnetic signals from said transmitter are not substantially present then the electronic indication of a loss of received signal is produced,
• (4) means for producing a warning stimulus to the pet, and
• (5) means for producing a control stimulus to the pet,
• such that when there is no electronic indication of a loss of signal level and there is no electronic indication of a loss of received signal, then there is no warning stimulus and there is no control stimulus to the pet, when there is an electronic indication a loss of received signal, then there is a warning stimulus to the pet, and when there is an electronic indication of a loss of signal level and there is an electronic indication of a loss of received signal, then there is a control stimulus to the pet.

• (f) producing no warning stimulus to the pet when there is no electronic indication of a loss of signal level and there is no electronic indication of a loss of received signal;
• (g) producing a warning stimulus to the pet when there is an electronic indication of a loss of signal level and there is no electronic indication of a loss of received signal;
• and
• (h) producing a control stimulus to the pet when there is an electronic indication of a loss of signal level and there is an electronic indication of a loss of received signal.
