Methods and devices for repelling mosquitoes may operate by generating the sounds of fore and hind pairs of dragonfly wings, which may be dragonfly wing beat sounds. Such sounds may be generated using digital or analog circuitry. The digital sounds may be recordings of synthesized or enhanced sounds of dragonfly wings beating. The device may take the form of a button that may be worn or otherwise carried by a user.

An aerial vehicle according to the present invention includes: at least one rotor configured to generate an air flow for lifting; and at least one sound producing structure having an opening and configured to produce sound for scaring birds and animals when the air flow generated by the rotor causes air to flow into the opening.

An electronic apparatus and a method are provided for detection of animal intrusions and control of a repellent mechanism to prevent such intrusions. The electronic apparatus controls an image-capture device to acquire an image of a house yard and selects a set of zones in the acquired image based on a user-specified setting. The electronic apparatus detects an animal in the acquired image and controls the repellent mechanism based on a determination that the detected animal is in a zone which is among the selected set of zones, to target the detected animal.

An unmanned aerial vehicle according to the present invention includes: a main body; an arm that extends from the main body to support a rotor; a first electrical conductor which is supported by the arm and to which a voltage is applied; a second electrical conductor which is supported by the arm and spaced apart from the first electrical conductor and to which a voltage lower than the voltage applied to the first electrical conductor is applied; and a controller configured to control electrical supply to the first and second electrical conductors.

A system useful to protect a real estate property includes at least one sensor configured to monitor presence of a nuisance animal on the real estate property, a computerized control module including programming to diagnose the presence of the nuisance animal based upon data from the at least one sensor, and at least one mobile robotic device. The mobile robotic device is configured to move to a location of the nuisance animal on the real estate property based upon the data from the at least one sensor and emulate a predator to move the nuisance animal.
