The present invention provides for animal containment through a system having a containment collar and GPS (Global Positioning System), RF (Radio Frequency), or INS (Inertial Navigation System) data, or a combination thereof, to define the perimeter of a containment area. A receiver is mounted to the containment collar, worn by an animal, which contains positioning electronics, memory and warning outputs. The user defines the perimeter by programming “waypoints” (positions on the perimeter) into the collar. The system provides an audible warning when the animal is within a user programmable distance of the perimeter, and then provides an adjustable correction, such as an electrical impulse to the animal when the perimeter boundaries are exceeded. Upon perimeter violation and initial correction of the animal, the system dynamically changes the position of the boundary encompassing the animals current but prohibited position. Then the dynamic boundary may be gradually or incrementally changed so as to direct the animal toward the original perimeter.

The system incorporates wire deflection, taut wire detection for perimeter security applications. Generally, the system of the invention provides intrusion detection by an internal mechanism. The internal mechanism can detect wire deflection in any direction. In turn, given a sufficient amount of wire deflection, a security system is signaled. However, the force required to sufficiently deflect the wires is high enough so as to minimize nuisance alarms. The internal mechanism is generally held within a structure so that it is protected from tampering. As such, the internal mechanism is also kept separate from the wire array so that it is protected from attempts by an intruder to isolate the wire array.

A floating dispenser having an external float or an internal float for supporting a cartridge or cartridges for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser having cartridges rotationally positionable with respect to one another to control the rate of dispensing while the dispenser floats in an upright condition with the floating dispenser changing its flotation orientation in response to consumption of the dispersant or dispersants in the a cartridge to thereby provide a visual alert to replace a spent cartridge with a fresh cartridge. In addition the inventions described herein permit changing the dispensing nature of the system from a multiple dispensing system to a single dispensing system without changing the floating characteristics of the floating dispensers through replacement of a dispersant in one of the cartridges with an inert or ballast material that has no effect on the water characteristics.

A floating dispenser for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser floating in an upright condition when a dispersant is present in a dispenser cartridge of the floating dispenser with the dispenser self inverting 180 degrees in response to consumption of the dispersant in the dispenser cartridge to thereby provide a visual alert that one should replace the dispenser cartridge in the dispenser with a fresh dispenser cartridge.
