ABSTRACT:
A system for dispersing birds away from airfields includes a central computer unit and a base antenna system, a hand held transmitter, and a plurality of remotely disposed, positionable gas cannons, each cannon is connected to a single control unit. Each gas cannon produces a high decibel explosion by feeding a combustible gas from a pressurized storage tank housed within the cannon control unit. In addition, the system includes an endless recording of chaotic noises, such as barking dogs, sirens, breaking glass, etc., for broadcasting. The noise broadcasts are via all weather speakers remotely disposed along with the gas cannons. The noises, broadcast in 15-20 second bursts, are made simultaneously or alternatively to the gas cannons. Each control unit has a radio receiver powered by a battery. The central computer unit uses control software and a base antenna enabling transmission of operation instructions to the control units. An operator using the system may select the time and duration in which any combination of cannon firings or noise broadcasts. The hand held transmitter included with the system is used for remote communication to and operation of the central computer unit via the base antenna system.
