The sound waves are delivered by the medium of conductor power wires to all indoor power lines and ground wires connected to the apparatus of the invention, and are distributed all over room corners, cracks on walls, and gaps so that insects will feel uncomfortable and get out of hidden places, as a result, the apparatus can achieve its effect.

Abstract: The device comprises a housing featuring a transparent window behind which is positioned an infrared detector. A disc in the same plane as that of the front face of the housing can rotate around its central axis perpendicular to said plane.

Abstract: An electronic alarm is disclosed for use in a moving vehicle which generates ultrasonic sound for preventing animals from moving into the path of the vehicle. The device includes a simplified driver circuit for generating electrical impulses in the form of square waves having constant peak-to-peak voltages. The driver generates the square waves with periodic, sequentially increasing wave frequencies followed by sequentially decreasing wave frequencies. A coupling transformer converts the square waves into electrical sine wave voltages having high peak-to-peak voltages to cause a piezo-electric transducer to emit intense, ultrasonic sounds of periodically increasing frequencies followed by periodically decreasing frequencies simulating the warble effect of a siren without excessive heating and premature failure of the transducer. The ultrasonic warble effect confuses the animal to prevent inadvertent movement by the animal into the oncoming vehicle's path without injury to the animal.

Abstract: A system and method for developing acoustic underwater stimuli for guiding aquatic animals such as fish, to or from an underwater area. Fish captured from the underwater area are placed in a sound recording chamber and their sounds recorded. The spectrum of the recorded sound is analyzed and is used to vary a primary sound spectrum is accordance with predominate frequencies contained therein to create a sound believed to have the most efficient guidance effect on the fish since the fish are believed to be most responsive to sounds produced by the fish themselves.
