Abstract: Disclosed is an ultrasonic pest deterrent device adapted for use in greenhouses and gardens, comprising a printed circuit board, output signal transducer and a housing adapted to shroud the components of the assembly within its waterproof interior. The device comprises a ramp signal generator and voltage control oscillator adapted to sweep between a chosen set of switchable frequency pitch ranges and tones, a sweep stop for single tone testing, a confidence test button, a power switch and indicator light. The confident test button provides an audible tone within human hearing range to ensure the device is operational, while the power indicator light provides a visual means of verifying operation when the device is emitting signals in the ultrasonic range. A timing circuit disables or modulates the device from continuous operation, saving battery life and randomizing the output signal for increased pest annoyance and deterrence.

Abstract: A rat guard and method utilizing a flexible shield affixed to a plastic sheath positioned on a mooring line to prevent entry onto or exit from the ship by vermin. An electric grid is positioned on an insulated pad on the sheath which is electrically connected to the shield for receiving power from an acoustical generator also connected to the shield and spaced therefrom. The acoustical generator directs ultrasonic acoustic signals in a variable frequency range toward the shield to frighten rats or other vermin therefrom.

The shield provides another obstacle to prevent advancement and is affixed to the sheath on the mooring line. The shield is flexible and remains in place during high winds and other adverse weather conditions.
