A problem to be solved by the present invention is to prevent an aquatic creature from jumping out of a water tank without directly contacting the aquatic creature; and a jump-out prevention device for the aquatic creature, which can solve or reduce the problem, is provided.

The jump-out prevention device for the aquatic creature includes electrode parts arranged along an inner perimeter of a water tank for keeping the aquatic creature; and a power supply part electrically connected to the electrode parts, and configured to apply electrical pulses to the electrode parts. The electrode parts extend in a horizontal direction partially or entirely over the inner perimeter of the water tank, and are arranged in a predetermined underwater region in the water tank. The electrical pulses are applied to the electrode parts.

An insulator for notifying an animal when an electric fence is provided. The insulator may include a clip for attaching the insulator to the fence. Metal contact points may draw power from the electric fence when the fence is active, or the insulator may be powered through induction. The insulator may also include a circuit board or controller that receives power from the fence and translates it into an output directed to a notification device. The notification device may comprise a light that produces a visual notification or a speaker that produces an audible notification.

A high-voltage power source device includes: a first terminal connected to a first end of an electrical wire disposed around a predetermined region; a second terminal connected to a second end of the electrical wire; a high-voltage generation circuit connected to the first terminal and generating high-voltage electricity; a voltage detection circuit connected to the second terminal, and measuring a voltage value of the high-voltage electricity at the second terminal and determining presence of an abnormality in the electrical wire, based on a measured voltage value; a timing circuit instructing the high-voltage generation circuit to generate high-voltage electricity at a timing when the high-voltage electricity is generated, and sending an instruction to measure a voltage value of the high-voltage electricity at the second terminal to the voltage detection circuit; and a notification circuit for notifying a determination result of the voltage detection circuit to outside.

Apparatus and associated methods relate to a pest repelling magnetic field generating device (PRD) having a temperature sensor to detect the temperature of a solenoid coil during operation. The detected temperature to be used to ensure that the PRD operates within an ideal temperature range. Additionally, a fan is oriented within a housing of the PRD to force the flow of air from inside a housing of the PRD to outside a housing the PRD. In an illustrative example, the PRD may shut off if the temperature of the solenoid coil moves outside the ideal temperature range. By operating the PRD within an ideal temperature range, the service life of the PRD may be extended. Further, the fan may mitigate dust collection within the housing of the pest repelling magnetic field generating device.
