  • System 100 includes an emitter 106.
  • Emitter 106 is configured to emit (e.g., beam, transmit, send, etc.) an ultrasonic sound beam 108.
  • the term "ultrasonic" applied to sound in this application refers to anything above the audible frequencies of sound for humans (approx. 20 kHz).
  • Emitter 106 may be configured to transmit the ultrasonic portion of beam 108 in a specified direction.
  • Emitter 106 may achieve high directivity (narrowness) by using ultrasonic sound.
  • the ultrasonic sound has shorter wavelengths than audible frequency sound, increasing its directivity.
  • the ultrasonic sound beam 102 is configured to demodulate or down-convert from an ultrasonic sound to an audible sound 110 for the bird 102.
  • the audible sound frequency bandwidth is dependent upon the hearing range of the subject.
  • the audible sound range for humans is in the range of approximately 20 Hz to 20 kHz, but birds and other animals (e.g. bats) have different audible sound frequency ranges. Therefore, the term "audible sound” is not intended to refer to a particular fixed frequency band and instead simply refers to the range of hearing of the subject animal.
  • Modulation is the process of including information (such as a voice) onto a carrier signal, usually sinusoidal in shape, in order to transmit that information.
  • Emitter 106 is configured to transmit ultrasonic sound 108, which is then down-converted (i.e., the frequency of the sound wave decreases) through the nonlinear propagation characteristics in air to create an audible sound 110 at or near the bird 102. This happens when two sound waves with different frequencies are radiated
  • the audible sound modulated into the high frequency ultrasonic carrier sound may be selected to attract or repel the bird 102.
  • a sound of a predator may be selected to repel the bird 102 and a sound of a mate or prey may be selected to direct (e.g., attract or repel) the bird 102.
  • the audible sound may be similar to the mobbing calls (i.e. calls to harass a predator) of a mobbing species of bird.
  • mobbing calls may provide a signal to nearby birds to join in on the mobbing activity and may differ in frequency depending upon the situation. Therefore, the frequency of the audible sound may be selected (e.g., in a range between 4 kHz and 8 kHz) to promote the desired activity of nearby birds.
  • the audible sound may be specifically configured for use with bats (e.g., similar to warning sounds produced by tiger moths as a defense against bats).
  • System 100 may include a director 112, which is configured to direct the ultrasonic sound beam toward the bird 102 away from an object, such as a wind turbine 116.

  • Method 300 includes detecting the bird (step 302).
  • the detector uses radar. Radar is an object-detection system that uses radio waves to determine the direction, range, altitude, or speed of objects.
  • the detector uses LIDAR. LIDAR is an optical remote sensing technology that can measure the distance to, or other properties of a target by illuminating the target with light. For example, it may use pulses from a laser.
  • the detector uses ultrasonic sound.
  • the detector uses a camera or multiple stereoscopic cameras.
  • Method 300 further includes identifying the type of bird (step 304).
  • the detector identifies that the bird is ringed (i.e. tagged with an identifying band) and uses that information to identify the type of bird. If the detected bird is identified as a type of bird that should be directed, for example, a raptor, the detector will determine the location of the bird (step 308).
  • the word "directing" is used to mean regulate and control or influence the course of flight of the bird toward a certain desirable area or away from an undesirable area. If the bird is located within the specified area, then the beam will be directed toward the bird (step 310).
  • the detector is configured to identify the actions of the bird (step 314). In one exemplary embodiment, the detector identifies if the bird is flying in a vertical or horizontal direction or toward or away from the circumference of the specified area. Based on the actions of the bird, an ultrasonic sound may be selected (step 316), a beam of ultrasonic sound generated (step 318) via, e.g., a propagator, such as an ultrasonic transducer or speaker, and the beam then transmitted toward the bird (step 320). The ultrasonic sound beam is configured to down-convert to audible sound in the bird or near the bird (step 322).
  • a propagator such as an ultrasonic transducer or speaker
  • the emitter is configured to direct the beam of ultrasonic sound toward the bird so that the ultrasonic sound down-converts to an audible sound directly in the tissues of the bird's body (i.e., the density of the bird's body acts to down-convert the high frequency ultrasonic sound to lower frequency audible sound).
  • the emitter is configured to beam the ultrasonic sound toward the bird where the atmosphere demodulates or down-converts the ultrasonic sound to audible sound at or near the bird.

Abstract

L'invention concerne un système pour éloigner un oiseau d'un équipement, qui comprend un émetteur configuré pour transmettre un faisceau de son ultrasonore modulé par fréquence audio. Le faisceau de son ultrasonore modulé par fréquence audio est configuré pour convertir à la baisse une fréquence dans l'atmosphère pour produire un son audible spécifié pour un oiseau à une distance sélectionnée éloignée de l'émetteur.
