SensorNet™

These two diagrams describe a device that could be used to prevent small UAVs (drones) from entering a walled structure/area/compound by suspending a net, as described below over the area. This could be accomplished by draping the net over poles and attaching it to wall edges. If an area away from any walls was to be protected, the net could be suspended entirely by poles or other upwardly extending structural elements. In an area surrounded by buildings, the net could be suspended entirely by the buildings. The net would enclose the entire area. This net contains conductive elements woven in at least one axis to create a sensor net.

On one side of the net, it utilizes a power supply to generate a low voltage signal through the conductive elements. On the other side of the net, it uses a continuity scanning computer to independently and continuously scan for signal continuity. If no continuity is detected in one or more of the elements, it is determined that the net has been broken and compromised which in turn sends an alarm to the user.

Although the diagrams label the net as a “kevlar net” a wide variety of materials could be used, including a range of polymers and even organic woven material, such as cotton. Also, a mixture of materials could be used. In one embodiment, insulated wires are used. The conductive elements are generally thin enough so that the impact of a drone would sever the conductive element, and thereby break the circuit.

Diagram 1 shows a net interwoven with conductive elements along one axis terminated on both sides of the net which allows the threads to be powered by a power supply from one side and terminated individually at a continuity checker on the other side along with the system computer.


















Diagram 2 shows the net draped over an enclosure and using support poles as required. The net may consist of multiple net and poles, as required to enclose an entire area.
