Abstract
A system for directing a bird away from equipment includes an emitter configured to transmit a beam of audio-modulated ultrasonic sound. The beam of audio-modulated ultrasonic sound is configured to frequency down-convert in the atmosphere to produce a specified audible sound for a bird at a selected distance away from the emitter.
Claims12
A system for directing a bird away from equipment, comprising:
- an emitter configured to transmit a beam of audio-modulated ultrasonic sound;
- and
- a detector comprising at least one of a camera, radar, and LIDAR configured to:
- detect the bird,
- identify the type of bird in response to detecting the bird,
- determine if the identified bird is a type of bird to be directed, and in response,
- determine a location of the bird relative to the equipment;
- a director in communication with said emitter and said detector, said director configured to control and direct the transmitted beam of the emitter based on at least one of the identified type of bird and the location of the bird relative to the equipment;
- wherein the beam of audio-modulated ultrasonic sound is configured to frequency down convert in the atmosphere to produce a specified audible sound for the bird at a selected distance away from the emitter, wherein the specified audible sound is selected from the group of audible sounds consisting of a sound of a predator, a sound of a mate, a sound of prey, and a mobbing call;
- wherein the specified audible sound is selected based on the type and location of the bird;
- wherein the sound of a predator is selected to repel the bird away from an undesirable area;
- and
- wherein the sound of a mate or prey is selected to attract the bird to a desirable area.
