  • Animal control system
    Patent number: 6575120
    Abstract: 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.

  • Animal control system
    Patent number: 6467435
    Abstract: 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.

  • Animal control system
    Patent number: 6360698
    Abstract: 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.
