Abstract: A method and a device for automatically detecting and signaling the presence of prey caught in a trap. The trap has inlet ports equipped with a one-way inlet mechanism such that once a rodent has passed a central point the rodent is contained within the trap. After the rodent has passed the central point, the trap is reset to the start position in order to attract additional prey. The trap is provided with a device for signaling the presence of vermin in the trap. The mechanism may be operable via a push button operated by movement of the vermin. Alternatively, means for detecting the rodent may include the use of vertical or horizontally elongated elements that are actuated by the movement of the vermin. A further embodiment includes a photocell, or a sensor, to indicate the presence of rodents. The mechanism for signaling may include lights or sound devices that can be secured to the trap or remotely activated via wired or wireless means.

Abstract: A pest repeller including at least a first ultrasound transmitter mounted on a base and a second transmitter rotatably mounted above the first transmitter. Both transmitters can be rotatably mounted on a common post carried by the base. The arrangements permit a greater ultrasound coverage of an area because of the relative rotation of the superimposed speakers.

Abstract: A pest deterrent device attracts the attention of a pest with ultrasonic noise and then produces a series of flashes to drive off the pest. In one embodiment, the device continuously produces ultrasound, changing the ultrasound when a pest is detected. In another embodiment, the device does not produce ultrasound until a pest is detected. In a further embodiment, the flash charging circuit is used to modulate the ultrasound while the flash is operated. In a particular embodiment, four ultrasonic speakers are arranged in a series-parallel configuration with a total capacitance of about 0.2 micro-Farads achieve 120 dB of sound output with a supply voltage of about 12-18 V.

Abstract: This disclosure concerns an invention used to deter auto collisions with animals, and more specifically to allow standard automobile horn to be altered in a manner such that the noise alerts animals, particularly deer, to the presence of an approaching vehicle. A timer/oscillator is selectively connectable between the vehicle horn actuator (e.g., the button on the steering wheel of the vehicle) and the vehicle horn. When the timer is connected between the horn actuator and the horn, a continuous input to the horn actuator is converted to an intermittent horn output (preferably cycling between 2-20 Hz), this intermittent horn output being synchronized with the timer pulses. Such cycling of the horn causes a flight response in animals when sounded in their vicinity.

Abstract: A hazard warning device for night-migrating birds is provided which warns the birds of the presence of a fixed structure or obstacle, e.g., a building or communications tower, against which the birds could collide during night-migration. The device includes a speaker affixed to the structure and a recorder connected to the speaker for, when activated, supplying to the speaker, for continuous broadcast thereby, an infrasonic signal which naturally causes the birds to avoid the structure. In one embodiment, the signal has a frequency close to that of a natural topographic feature and causes the birds to avoid the structure based on the workings of the innate navigational system of the birds. In another embodiment, the recorder supplies a signal which reproduces or mimics the sound of thunder and/or the sound of a lightning strike.

Abstract: An external stimuli is provided that alerts animals to danger and/or repels the animals from certain areas. More specifically, the system and method of the present invention uses an external stimuli, such as, for example, pulsing microwaves, vibration or supersonic sound waves, in order to alert birds or other animals of danger and/or repel these same birds or animals from specific areas. These produced external stimuli may provide a reversible unpleasant sensation to the birds and other animals so that they will not only be repelled from a specific area, such as an airport, but also will avoid returning to such area. One such unpleasant sensation that is virtually harmless to the birds and other animals is the sensation of dizziness.
