Abstract
An animal control apparatus which includes a conductive barrier and a self contained power source. A switching circuit is provided which couples the power source with the conductive barrier. The switching circuit includes an energizing switch for supplying power from the power source to the conductive barrier. The energizing switch is activated by a proximity sensor upon the proximity of an animal being sensed. The animal coming in contact with the conductive barrier receives a non-lethal shock. A timer is provided for deactivating the energizing switch to disconnect the conductive barrier from the power source upon a preset time interval having elapsed.
Description
TITLE OF THE INVENTION:
Animal Control Apparatus NAME ( S ) OF INVENTOR ( S ) Robert Laurel Sterling FIELD OF THE INVENTION
The present invention relates to an animal control apparatus and, in particular, an apparatus for preventing beavers from blocking culverts.
BACKGROUND OF THE INVENTION
When beavers block culverts, the resultant water diversion and flooding causes considerable damage to our highway systems.
SUMMARY OF THE INVENTION
What is required is an animal control apparatus that can be used to discourage activity by beavers.
According to the present invention there is provided an animal control apparatus which includes a conductive barrier and a self contained power source. A switching circuit is provided which couples the power source with the conductive barrier. The switching circuit includes an energizing switch for supplying power from the power source to the conductive barrier. The energizing switch is activated by a proximity sensor upon the proximity of an animal being sensed. The animal coming in contact with the conductive barrier receives a non-lethal shock. A timer is provided for deactivating the energizing switch to disconnect the conductive barrier from the power source upon a preset time interval having elapsed.
The animal control apparatus, as described above, discourages the activities of beavers by administering a non-lethal shock. At remote locations, there is no readily available power so a self contained power source, such as a battery is used. A battery at a remote location will have an

SUMMARY OF THE INVENTION
What is required is an animal control apparatus that can be used to discourage activity by beavers.
According to the present invention there is provided an animal control apparatus which includes a conductive barrier and a self contained power source. A switching circuit is provided which couples the power source with the conductive barrier. The switching circuit includes an energizing switch for supplying power from the power source to the conductive barrier. The energizing switch is activated by a proximity sensor upon the proximity of an animal being sensed. The animal coming in contact with the conductive barrier receives a non-lethal shock. A timer is provided for deactivating the energizing switch to disconnect the conductive barrier from the power source upon a preset time interval having elapsed.
The animal control apparatus, as described above, discourages the activities of beavers by administering a non-lethal shock. At remote locations, there is no readily available power so a self contained power source, such as a battery is used. A battery at a remote location will have an
2 extremely short life span if required to constantly be supplying power to the conductive barrier. For this reason a switching circuit is provided which provides power to the conductive barrier only when required to discourage the activities of an animal in the proximity. The supply of power is maintained to the conductive barrier only for such preset time interval as may be considered necessary to discourage the animal. In accordance with this teaching the life span of the self contained power source is prolonged, reducing the required service intervals at remote locations.

FIGURE 3 is a block diagram of the components of the animal control apparatus illustrated in FIGURE 1.
DETAINED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, an animal control apparatus generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 3.
Referring to FIGURE 3, animal control apparatus 10 includes a conductive barrier 12 and a self contained power source 14. A switching circuit 16 is provided which couples power source 14 with conductive barrier 12. Switching circuit 16 includes an energizing switch 18, a proximity sensor 20 and a timer 22. Energizing switch 18 has an "on" setting and an "off" setting. Energizing switch 18, which is normally in the "off" setting, is switched from the "off" setting to the "on"
setting upon receiving an electrical signal from proximity
3 sensor 20 upon the proximity of an animal being sensed. When energizing switch 18 is "on" power is supplied from power source 14 to conductive barrier 12, so that an animal coming in contact with conductive barrier 12 receives a non-lethal shock. Timer 22 is provided for deactivating switching circuit 16 by switching energizing switch 18 from the "on" setting to the "off" setting upon a preset time interval having elapsed.
This disconnects conductive barrier 12 from power source 14.
The use and operation of animal control apparatus 10 will now be described with reference to FIGURES 1 through 3. The example selected is that of a culvert 24 which is being threatened with blockage by the activities of beavers.
Referring to FIGURE 1, culvert 24 is cylindrical with open ends 26. Referring to FIGURE 2, conductive barrier 12 is disposed across one or both of open ends 26 of culvert 24. Open ends 26 of culvert 24 are identified by marker posts 13, which also serve to support the wires of switching circuit 16. Proximity sensor 20 is mounted on a sensor support 28 to provide a detection area across open end 26 of culvert 26. Proximity sensor 20 has a detection range sufficiently large, so as to detect an animal approaching said culvert 24, but not detect an animal passing by at a distance from said culvert 24. There are various types of proximity sensor 20 that can be used, including motion detectors and heat sensors that will detect the body heat of an animal. When proximity sensor 20 detects an animal in proximity to culvert 24, energizing switch 18 is activated by a signal from proximity sensor 20 to switch from the "off" setting to the "on" setting and power is supplied from power source 20 to conductive barrier 12. The animal coming in contact with the conductive barrier 12 receives a non-lethal shock. Timer 22 measures a preset time interval elapsing from the latest time of detection of an animal by proximity sensor 20. When the preset time interval has elapsed, and if there is no subsequent detection of an animal proximate to culvert 24 by proximity sensor 20 within the preset time interval, timer 22 sends a signal to energizing
This disconnects conductive barrier 12 from power source 14.
