  • Portable electronic multi-sensory animal containment and tracking device
    Patent number: 6561137
    Abstract: The present invention 10 discloses a portable electronic, multi-sensory animal containment and tracking device which comprises a transmission cable 20 that is placed directly upon the ground to define a selective containment area 18 which cable 20 is plugged into and operated by a base unit 26 which can be powered by either rechargeable batteries 30 or a conventional 110-volt AC external power source 14. The transmission cable 20 has a plastic or rubberized coating 78 that is of a blue-violet and/or a yellow color to enhance the transmission cable's visibility to a canine 16. The transmission cable 20 emits a radio frequency output generated by a frequency generator 42 disposed in the base unit 26 and also activates an audible alarm through speaker 58 disposed in the remote unit 28 attached to the animal's collar 22 which thereby warns the animal 16 that it is close to the boundary line 20 and should retreat.
