  • Animal containment/repellant system having an internal and an external antenna
    Patent number: 8430064
    Abstract: Described is an animal containment/repellant system for, among other things, containing an animal within a containment area and simultaneously repelling the animal from a restricted area. More specifically, the animal containment/repellant system includes multiple signal transmitting antennas that simultaneously define multiple cooperating containment areas, restricted areas, or combination of containment and restricted areas.

  • Solar Powered Animal Containment/Repellent System
    Publication number: 20110234410
    Abstract: Described is an animal containment/repellant system for containing and animal within or repelling an animal from a designated area and for optimizing an integral power source of the system. More specifically, the animal containment/repellant system supplements the operating power provided by its internal power source with power derived from solar energy and charges its power source using the derived power. Additionally, the animal containment/repellant system employs a power conservation scheme to minimize the use of its internal power source.
