Certain types of fish respond differently to certain stimuli than other types of fish. Particularly, predetermined sound or vibration can cause certain types of fish to move away or jump. These reactions by particular types of fish can be used to capture the fish or prevent then from accessing parts of water systems. An exemplary capture mechanism employs multiple receptacles adapted to catch jumping fish from the air. An exemplary barrier of directed sound can prevent fish migration.

The invention discloses a method of operating a system for neurofeedback (NFB) that includes trained animal in a feedback chain. Feedback chain consists of the following steps:
A.fwdarw.B.fwdarw.C.fwdarw.D.fwdarw.A wherein said steps are: A. real time recording of the subject's EEG performed by the user module and forwarded to the mobile module; B. analytics of the recorded signal performed by the mobile module and algorithmic decisioning about the stimulation form; C. forwarding the stimulation towards the animal by using of one or more ultrasonic speakers simultaneously wherein the information needed for the animal performance is forwarded in the form of a coded ultrasonic signal; and D. performing of a learned action by the animal triggered by the received ultrasonic signal from the step C which provides a stimulus to the subject exposed to the NBF training.

The present invention provides a roadkill and bird strike prevention system comprising: an ultrasound generating circuit module generating a control signal that generates frequency waves within predetermined ultrasound range; a connection wire electrically connecting between the ultrasound generating circuit module and a ultrasound output pad and transmitting the control signal generated from the ultrasound generating circuit module into the ultrasound output pad; and the ultrasound output pad attached to a body of a vehicle, such as a motor vehicle, an aircraft, and a watercraft, and outputting ultrasound waves using the control signal transmitted from the ultrasound generating circuit module through the connection wire.

Described herein are various systems and techniques for deterring wildlife from an area proximate a windmill. A flying wildlife emitter may be utilized for such techniques. The flying wildlife emitter may output soundwaves to deter wildlife, such as birds or bats, from entering an area around the windmill. The flying wildlife emitter may include a speaker for producing sounds as well as a controller and sensors for determining conditions around the windmill and for controlling the sound produced by the speaker.

A lice repellant assembly for repelling head lice includes an article of head gear that can be worn on a user's head. A sound emitter is disposed on the article of head gear. The sound emitter emits sound waves outwardly therefrom. Moreover, the sound emitter has an operational frequency of at least 20.0 Hz to repel lice from the user.

A rodent repellant device that is placed on the floor and emits a movable light beam in the local area causing rodents to flee. The light source is operable to move within the plane parallel to the floor and the light beam remains within a selected angle. The selected angle of the light beam is within 90 degrees and may be controlled using a convex lens. In this manner the light beams are prevented from reaching human eye level and disturbing human activity. The light source may be an array of light sources mounted on top of a body and positioned to emit light beams in 360 degrees. The device may incorporate ultrasonic speakers to maximize disturbance to rodents, and elements such as light sensors so that the device operates at night when rodents are active.

A pest repeller comprises a pest detector operable to detect the presence of a pest and then to generate an internal trigger signal, a speaker operable to produce ultrasound, and an antenna operable to transmit wirelessly and to receive wirelessly external trigger signals. A controller is configured to receive internal trigger signals from the pest detector and to receive external trigger signals from the antenna. Upon receiving an internal trigger signal, the controller is configured to provide a speaker drive signal to drive the speaker to produce the ultrasound, to generate an external trigger signal and to provide the external trigger signal to the antenna for transmission of the external trigger signal. Upon receiving an external trigger signal, the controller is configured to provide a speaker drive signal to drive the speaker to produce the ultrasound.
