The present invention provides a method of suppressing larvae of barnacles in the settlement stage from settling on a substrate in water by irradiating light comprising the spectrum of 409 to 412 nm and a part of 400 to 460 nm to larvae of barnacles in the settlement stage in a direction from the substrate to the larvae of barnacles in the settlement stage.

The present invention is a method of preventing settlement of a sessile organism on a structure in water, including irradiating light comprising the spectrum of 409 to 412 nm to the structure where settlement of the sessile organism is prevented.

An example of an apparatus for excluding birds from an enclosure may include a laser projector configured to project one or more laser beams and a controller configured to control an activation, a direction, and/or a pattern of the projection of the one or more laser beams. In various embodiment, the control may be configured to receive a switch signal indicating a state of an entrance of the enclosure and to control the projection of the one or more laser beams using the switch signal.

A system for repelling a pet from at least one predetermined area includes a first device adapted for positioning at the predetermined area. The first device includes at least one of a first receiver and a first transmitter. A second device is adapted for placement on the pet. The second device includes at least one of a second receiver and a second transmitter. At least one of the first device and the second device is configured to warn the pet when the second device approaches the at least one predetermined area, and thereby train the pet to stay away from the predetermined area.

The present application discloses a bird-repelling method, a bird-repelling apparatus, and a bird-repelling system. The bird-repelling method includes steps of: controlling a light-emitting device to emit blue light; controlling a sound producing device to emit sound waves; and repelling birds by the bird-repelling apparatus integrating blue light irradiation and sound wave emission. The blue light bird-repelling mode and the sound wave bird repelling mode complement each other. Light waves and sound waves generate a resonance effect, which can repel birds more effectively without causing harm to humans or birds. The present application can be widely applied to various fields requiring bird repelling, such as aviation, high-speed railways, electric power, agriculture, and the like.
