  • System and Method for Determining Proximity to a Wireless Boundary of Programmable Shape Used in Animal Containment
    Publication number: 20080186197
    Abstract: Described is a boundary proximity determining system for wirelessly defining a boundary having a programmable shape and for indicating the occurrence of a rover unit traversing the boundary. The boundary proximity determining system includes a base station unit that generates a plurality of magnetic fields. The boundary proximity determining system also includes a rover unit that is responsive to the generated magnetic fields such that the rover unit defines the boundary in terms of the intensities and polarities of the magnetic fields. The rover unit determines whether the rover unit is within or outside the boundary by determining the current location of the rover unit in terms of the intensities and polarities of the magnetic fields and comparing the current location to the boundary.

  • Wireless boundary proximity determining and animal containment
    Patent number: 7142167
    Abstract: A proximity detection system for determining when a single channel receiver becomes proximate to any point on a wireless closed boundary continuously generated by a transmitter. The transmitter includes a magnetic field generator broadcasting a composite, modulated, time-varying magnetic field signal of a particular carrier frequency. The receiver forms a measure of the broadcast magnetic field intensity incident to the location of the receiver or a measure of the power or energy of incident field.
