A refill kit for a device to dispense an air treatment chemical includes a substrate supported on a frame. The substrate is in the form of a puck, and includes sand, a binder, and an air treatment chemical. A candle is also provided, which is suitable to heat the substrate.

A non-lethal animal shepherding active denial system of directed electromagnetic energy having at least one emitter to provide low-energy radiation to deter and shepherd birds and other species away from dangerous areas such as airports or wind turbines. The directed electromagnetic energy may be emitted in a conical shape to target a precise area and to define at least one denial zone and at least one shepherding zone. The shepherding zone may create a pathway to shepherd animals away from the denial zone to allow the birds to safely escape from the denial zone. Objects within a shepherding zone are subjected to dielectric heating, such that the radiation penetration is very shallow, only heating the surface of the skin or fur. By employing a large spatial swath, lower energies (<1 kW), and time-varying intensity, birds and other species can be shepherded away from regions of interest.

An apparatus and a method for generating an alarm are provided. The apparatus includes at least one processor configured to implement: a determination unit analyzing at least one of an image, which includes an object, and a sound related to the object, and, as a result of the analysis, determining a type of the object; and an alarm generation unit controlling an alarm generator to generate an alarm according to a result of the determination performed by the determination unit.

A double-sided mosquito repeller includes a main shell. A first placement bin, a second placement bin, and an installation cavity are arranged on the main shell. The first placement bin and the second placement bin are respectively arranged on two opposite side walls of the main shell. The first placement bin and the second placement bin are each configured to receive a mosquito-repellent pad. The installation cavity is provided with a heating unit, a first heat conduction unit, and a second heat conduction unit. The heating unit is sandwiched between the first heat conduction unit and the second heat conduction unit and configured to heat the heat conduction units. The first heat conduction unit is configured to heat the mosquito-repellent pad in the first placement bin, and the second heat conduction unit is configured to heat the mosquito-repellent pad in the second placement bin.

An electrically heated barrier for containers storing organic waste that generates a temperature that blocks housefly maggots incubated in the container's waste from emerging to the exterior of the container, and that inhibits maggots and other crawling invertebrates on the exterior of the container from accessing the waste stored therein.

A snake deterrent device is provided. The device is comprised of a base comprised of at least one cooling element that cools at least one top plate. The element is preferably cooling tubing that cools the top plate at or below 50 degrees Fahrenheit, wherein the top plate is comprised of a conductive material. In this manner, the plate is cooled such that if a snake attempts to pass over the plate, the cooled temperature of the plate discourages the snake from entering into the structure or area.
