An improved animal control system for controlling the movement of an animal includes a transmitter/control unit for generating a frequency modulated transmit signal, an antenna defining an area and for radiating the transmit signal, and a battery-powered receiver/stimulus unit for receiving and discriminating the transmit signal and for applying a stimulus to the animal upon qualification of the received transmit signal. The system may be used to contain an animal within, or restrict an animal from, the defined area.

An animal control system is provided in which an AM transmission signal includes qualification criteria which upon proper decoding provides intended stimuli to an animal. The transmit signal comprises modulated pulses having a first amplitude and a second amplitude which upon decoding represent logic zero and logic one states. The receiver employs microprocessor based digital circuitry for decoding and processing of the AM transmit signal. The transmit signal is transmitted in alternating odd and even frames, each of which has particular characteristics and which upon proper decoding by the receiver causes successive weak and strong stimuli to be provided to the animal.

A receiver/stimulus unit for an animal control system is mounted on an animal collar. The unit includes a power supply enclosure for a power source such as a battery separate from a receiver enclosure containing signal receiving circuitry. The power source is in electrical communication with the signal receiving circuitry via an electrical communication path passing on or through a portion of the strap of the collar.

The present invention provides an automatic correction system and technique for a pet containment system in which the correction levels of the electrical stimulus and/or audio or visual warning are adaptively adjusted in accordance with the behavior of a particular dog or other animal. In one mode of operation, the system is set to a baseline correction level at which a predetermined warning such as an audible beep is provided when the animal enters a first detection zone, and a predetermined electrical stimulus is provided when the animal enters a second detection zone. The correction levels are automatically adjusted in response to one or more parameters of the animals behavior. One example of animal behavior to be corrected is repeated challenge by the animal to the system by repeated entry into the first or second detection zone within a defined period of time. Another example of behavior to be corrected is the animal remaining in a detection zone beyond a specified time period. Yet another example is the animal escaping from the defined perimeter.

A receiver for an animal control system having a correction monitor which indicates that the animal has attempted to challenge the system, as determined by the occurrence of one or more correction events within a specified period of time. A correction event occurs when a stimulus is applied to the animal. The stimulus may be an audible alert, or may be an electrical shock. The correction monitor is operative to monitor correction events and to provide an indication that an event has occurred. In one embodiment, the correction event can be signaled to a user at the receiver by use of an LED or other indicator or display which is latched on for a defined period of time. In another embodiment, the correction event can be signaled to a user at a central location, such as by an indicator or display in the animal owner's house. The correction event may also be signaled remotely via a communications path or network, and displayed in any suitable manner at one or more remote locations. The time of correction events and location information can be provided in association with the event indication.

A device for monitoring the integrity of an antenna wire loop, such as for a pet containment system, and a system using the monitoring device are disclosed. The device can be incorporated in the transmitter portion of the pet containment system or can be a stand-alone device electrically and operationally coupled thereto. The device includes a current monitoring portion that monitors the current driven in the antenna wire loop and a display portion that displays the intensity of the electromagnetic field in appropriate units, such as feet.

An improved animal control system for controlling the movement of an animal includes a transmitter/control unit for generating a Frequency Shift Keying (FSK) transmit signal, an antenna defining an area and for radiating the FSK transmit signal, and a battery-powered receiver/stimulus unit for receiving and discriminating the FSK transmit signal and for applying a stimulus to the animal upon qualification of the received FSK transmit signal. The system may be used to contain an animal within, or restrict an animal from, the defined area.

A system and method for monitoring and reporting to a system user, operational information pertaining to a base station and one or more collar modules of an animal control and activity level and behavior information pertaining to one or more monitored pets. Information regarding the base station and the one or more collar modules is communicated to the system user via a communications portal and a web application executing on a web server. System users interface with the web application via a computer network, e.g. the Internet, and may access information from a location remote from the animal control system through the web application. System users may also modify the operation of the base station, collar modules and/or communications portal by issuing commands to such devices through the web application. The web application also issues alerts and/or notifications to one or more system users.
