Abstract: Devices and methods for monitoring operation of components of animal containment systems, and for notifying responsible parties of faults, status, or changes of status of such systems are provided. A device for monitoring operation of an animal containment boundary defining apparatus detects presence, absence, magnitude, and/or change in magnitude of at least one electrical signal in a boundary defining wire, and generates a responsive alarm signal. Devices for affecting operation of a premises security system with a motion detector involve use of a secondary detector to detect presence, absence, proximity, status, or movement of an animal tag or collar. A secondary animal tag or collar with detection and communication capability may be used to detect operation status or failure of a primary animal tag or collar arranged to cooperate with an animal containment boundary defining element (e.g., buried wire).

Abstract: A system for invisible fencing for animals, that is a device mounted on animals. The device checks GNSS position measurements against an area that is defined in the device. The area can be defined as a combination of several areas with different characteristics. An area may also be defined as dynamic. The system calculates the shortest distance to this area based on actual GNSS position. If position measurements show that the animal has a position that is outside the area, correction will be performed as a combination of audio signal and electric shock. The correction is made by increasing the audio frequency proportionally with the calculated distance to the area. When the audio frequency has reached an upper limit, one single electric shock is given, and possible further correction is resumed from the position where the electric shock was given.

Abstract: A system for controlling pets utilizes a low power transmitter to create avoidance zones in which one pet wearing an animal control receiver can enter but in which a second pet is deterred from entering.

Abstract: In various embodiments, a method of controlling a position of an animal includes tracking a position of the animal using a positioning system, such as a global positioning system. A time-varying position of a base object is also tracked using the positioning system, and a relative position of the animal with respect to the base object is determined, based on the positions of the animal and the base object. When the relative position exceeds a minimum value, a stimulus is provided to the animal to encourage the animal to reduce the relative position. A user of the system may define a region for the animal using a map of the surrounding territory.

Abstract: A wireless fencing system comprises a tetherless leash, a programming fixture, and, optionally, a terminal. The tetherless leash, which is attached to an animal that is to be monitored, establishes a “virtual” (i.e., barrier-free) perimeter based on geo-coordinates. The tetherless leash also monitors the position and movement of an animal relative to the perimeter, and delivers warnings, corrections, and praise to the animal in accordance with its programming. The programming fixture serves as a user interface during programming operations, since there are no exposed buttons by which a user can directly program the tetherless leash.

Abstract: A radial-shaped wireless fence system is provided that contains one or more dogs in a user-defined area without the need for a physical fence or underground wire. The system includes a base unit and at least one collar, and is easy to set up and use. Through improved filtering of consecutive distance measurement values taken between the base unit and the collar, errant measurement values are discounted in terms of their contribution to the current estimate of the dog's distance from the base unit. These filtering techniques, in combination with improved signal strength and antenna diversity in the communication between the base unit and the collar, improve the accuracy and consistency with which the dog's distance from the base unit is tracked so that unwanted corrections are not administered to the dog.

Abstract: Described is an animal containment system for containing an animal within a boundary, for maximizing the animal's usable area within the boundary, for not discouraging the animal from returning to within the boundary in the event the animal moves beyond the boundary, and for doing so without utilizing an independent polarity indicator. The animal containment system determines whether the animal is within the boundary or beyond the boundary by considering the polarity of an activation signal the animal containment system transmits from the boundary and receives at the location of the animal. The animal containment system determines the polarity of the activation signal by modulating the signal such that the modulation indicates the polarity of the activation signal. The animal containment system achieves the above-discussed features by delivering a stimulus to the animal only when it traverses the boundary from within the boundary.

That information forms the basis for the boundary definition used by the collar during monitoring operations.

Abstract: A wireless fencing system comprises a tetherless leash, a programming fixture, and, optionally, a terminal. The tetherless leash, which is attached to a monitored animal, establishes a “virtual” (i.e., barrier-free) perimeter based on geo-coordinates.

The programming fixture serves as a user interface during programming operations, since there are no exposed buttons by which a user can directly program the device. The wireless fencing system does not expand the perimeter in response to perimeter breach of a monitored animal. Rather, a protocol that monitors the animal's speed and location direction of movement relative to the perimeter and/or outbound way points is used.

Abstract: An electronic animal containment system with direction-of-approach determination, or direction-sensitive animal containment system. The direction-sensitive animal containment system generally contains a transmitter unit connected to a wire loop bounding a containment area and a receiver unit carried by the animal. The direction-sensitive animal containment system of the present invention generates a containment field having polarity and retains the polarity information when the containment field is sensed using a sensing coil optimized along the azimuth. The receiver unit also generates a gravity vector to determine the orientation of the receiver unit. The gravity vector is combined with the containment field vector to produce a function that automatically yields a sensing coil output that is independent of the orientation of the receiver unit. The polarity of the sensing coil output allows determination of the direction from which the receiver unit is approaching the wire loop.
