Wireless pet containment system

Claim 1

A pet containment system comprising: (a) a transmitter for transmitting a series of electromagnetic signals, wherein said transmitter further includes: (1) means for modulating the electromagnetic signals, wherein the signals are modulated to produce non-random patterns of electromagnetic energy, (2) means for transmitting the non-random patterns of electromagnetic energy, 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, 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 is produced, (3) means for comparing the phase of the received electromagnetic signals from said transmitter with a predetermined phase and for producing an electronic indication of a loss of phase, wherein if the phase of the received electromagnetic signals from said transmitter are not substantially in phase with the reference phase then the electronic indication of a loss of phase 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 and there is no electronic indication of a loss of phase, then there is no warning stimulus and there is no control stimulus to the pet, when there is an electronic indication of a loss of signal and there is no electronic indication of a loss of phase, then there is a warning stimulus to the pet, and when there is an electronic indication of a loss of signal and there is an electronic indication of a loss of phase, then there is a control stimulus to the pet.

Claim 11

A method for producing an area for the containment of a pet, the method comprising: (a) transmitting a series of electromagnetic signals, further including: (1) modulating the electromagnetic signals, wherein the signals are modulated to produce non-random patterns of electromagnetic energy, and (2) transmitting the non-random patterns of electromagnetic energy; (b) attaching a releasable electromagnetic energy receiver to a pet; and (c) receiving the series of electromagnetic signals with the releasable electromagnetic energy receiver: (d) comparing the signal level of the received electromagnetic signals received with the releasable electromagnetic energy receiver with a predetermined level and producing an electronic indication of a loss of signal, wherein if the signal level of the received electromagnetic signals with the releasable electromagnetic energy receiver is less than the predetermined level then the electronic indication of a loss of signal is produced; (e) comparing the phase of the received electromagnetic signals received with the releasable electromagnetic energy receiver with a reference 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 are not substantially in phase with the reference phase then the electronic indication of a loss of phase is produced; (f) producing no warning stimulus and no control stimulus to the pet when there is no electronic indication of a loss of signal and there is no electronic indication of a loss of phase; (g) producing a warning stimulus to the pet when there is an electronic indication of a loss of signal and there is no electronic indication of a loss of phase; and (h) producing a control stimulus to the pet when there is an electronic indication of a loss of signal and there is an electronic indication of a loss of phase.

Claim 12

A method for producing an area for the containment of a pet, the method comprising: (a) transmitting a series of electromagnetic signals, further including: (1) modulating the electromagnetic signals, wherein the signals are modulated to produce non-random patterns of electromagnetic energy, and (2) transmitting the non-random patterns of electromagnetic energy; (b) attaching a releasable electromagnetic energy receiver to a pet; and (c) receiving the series of electromagnetic signals with the releasable electromagnetic energy receiver: (d) comparing the signal level of the received electromagnetic signals received with the releasable electromagnetic energy receiver with a predetermined level and producing an electronic indication of a loss of signal, wherein if the signal level of the received electromagnetic signals with the releasable electromagnetic energy receiver is less than the predetermined level then the electronic indication of a loss of signal is produced; (e) comparing the phase of the received electromagnetic signals received with the releasable electromagnetic energy receiver with a reference 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 are not substantially in phase with the reference phase then the electronic indication of a loss of phase is produced; (f) producing no warning stimulus and no control stimulus to the pet when there is no electronic indication of a loss of signal and there is no electronic indication of a loss of phase; (g) producing a warning stimulus to the pet when there is an electronic indication of a loss of signal and there is no electronic indication of a loss of phase; and (h) producing a control stimulus to the pet when there is an electronic indication of a loss of signal and there is an electronic indication of a loss of phase.
