  "description_excerpt": "This invention pertains generally to electrical communications, and more particularly to condition responsive indicating systems with a radio link and including personal portable device for tracking location. The condition responsive indicating systems of the present invention monitor the specific condition of humans or animals. In one preferred manifestation, a fully self-contained collar designed in accord with the teachings of the present invention monitors the location of a pet such as a dog, and provides well defined and positive stimulus to train the pet to stay within a predetermined area.\n\nDogs are well known as “man's best friend” owing to the many beneficial services that they provide. However, and likely since mankind first befriended dogs, there has existed a need to control the territory that a dog has access to. There are many reasons that motivate this need, many which may be relatively unique to a particular dog or owner, and other reasons that are far more universal.\n\nIrrespective of the reason, there have been limited ways to communicate to a dog a territory that the dog should stay within, and to elicit this behavior from a dog. One method is a fixed containment structure such as a fence or building. A structure of this nature provides a physical boundary or barrier which blocks passage of an animal such as a pet or farm animal. As may be apparent, such structures are typically expensive and time consuming to install, and necessarily static in location. In other words, they are only useful at the location where they are constructed, and so are of no value when a pet and owner travel.",
