Invisible Fence - History

History

The first commercial invisible fencing system was designed to contain house pets within a predetermined area, which was patented by Richard Peck, owner of Invisible Fence Company in 1974. Peck’s invisible fence was also the first borderless containment system used to contain livestock. In 1987 Peck successfully contained domestic goats to a limited area using RF receiving collars intended for household dogs. In 1989 Thomas M. Quigley of Tri-Tronics successfully trained cattle to avoid specific areas, with less than two days of training using dog training collars. In 1990 Tri-Tronics successfully developed a RF receiver specifically designed for livestock to control heifers in Canadian fields and pens. In 1991 Brian Rose invented a RF receiver that controlled cattle with an electric shock that was delivered through a nose clip. In 1992 AgriTech Electronics developed an electronic ear tag which used audio and shock cues to control cattle and was researched to be 90% effective in preventing Texas steers and heifers from entering an exclusion zone.

Famous quotes containing the word history:

    Bias, point of view, fury—are they ... so dangerous and must they be ironed out of history, the hills flattened and the contours leveled? The professors talk ... about passion and point of view in history as a Calvinist talks about sin in the bedroom.
    Catherine Drinker Bowen (1897–1973)

    Modern Western thought will pass into history and be incorporated in it, will have its influence and its place, just as our body will pass into the composition of grass, of sheep, of cutlets, and of men. We do not like that kind of immortality, but what is to be done about it?
    Alexander Herzen (1812–1870)
