Abstract: A system for trapping animals includes a cable and an enclosure adapted to be suspended above a trap area by the cable. A release mechanism includes a pivotable member, and the pivotable member is configured to rotate about a pivot support between an engaged position and a released position. The pivotable member in the engaged position supports the cable to hold the enclosure in a suspended position, and the pivotable member in the released position releases the cable to allow the enclosure to fall from the suspended position and enclose the trap area. The system further includes an actuator, which in an extended position holds the pivotable member in the engaged position. In a retracted position, the actuator releases the pivotable member to allow the pivotable member to rotate into the released position.

Abstract: Individual zones are defined within a multi-zone assisted guidance region by storing a zone GPS data point target width, assigning GPS data points located within a perimeter and within the target width to a second zone, allotting GPS data points located interior of and distinct from the second zone and within the target width to a first zone; and finally ascribing unassigned GPS data points located interior of and distinct from the first zone to a safe zone. If there is not enough total width between perimeter points in a region to provide all zones at the target width, a data point width of more exterior zones are preferentially electronically maintained at the target width and more interior zones are reduced or eliminated. In addition, adjacent guidance zones have unique stimulation that acts through different neurological access channels to provide behavioral guidance to an animal.
