| 20100139576 | ELECTRONIC FENCE SYSTEM - An electronic fence system capable of guiding animals under training to return to a predetermined restricted area is disclosed. The fence system may utilize either a plurality of loops to determine direction of travel for a receiver unit or, alternatively, a GPS system. For embodiments utilizing the GPS system, electronic fences are defined in relation to GPS location information. A lock-down mode is used to contain an animal to a very constricted area when a control command is received to initialize the lock down mode or upon a specified condition. Specified conditions include the animal approaching or entering a specified area or, alternatively, a threshold level of charge being reached for a battery that provides power for the receiver unit. | 06-10-2010 |
| 20090000566 | ELECTRONIC FENCE CAPABLE OF GUIDING ANIMALS TO RETURN - An electronic fence system capable of guiding animals under training to return to a predetermined restricted area. The electronic fence generates electric shocks as the animals attempt to leave the predetermined restricted area and restrains the electrical shock when the animals return to the predetermined restricted area. The electronic fence includes a transmitter and a receiver. The transmitter transmits RF signals having a plurality of control signals such that different shock levels are generated responsive to the location of the animals within the predetermined restricted area. The receiver sets a shock wave level, selectively controls the generation of the electric shock and a high-frequency beep, automatically restrains the generation of the electric shock when an escaped animal returns to the predetermined restricted area, and generates an audible alarm and turns lamps on and off to indicate the location of the animal when it escapes from the predefined restricted area. | 01-01-2009 |
