  • Electronic cattle group system
    Patent number: 4910500
    Abstract: Livestock entering a border zone along a vehicle roadway are deterred by devices triggered into operation simultaneously with a remote alarm by interruption of photo-electric beams at ends of the zone from which the animals enter or exit. The deterring apparatus is reset to prevent operation in response to travel of a vehicle through the zone and is temporarily disabled by selective switch actuation.

  • Electronic cattle guard
    Patent number: 4503399
    Abstract: Livestock entering a border zone along a vehicle roadway are deterred by sequentially activated horn, smoke generating and odor emitting devices triggered in response to interruption of one photo-electric beam at that end of the zone from which the cattle enter. Travel of a vehicle through the zone sequentially interrupts the two beams at opposite ends of the zone to reset the deterring apparatus and cancel its operation.
