A system and method for driving geese away from an area employs predetermined random illuminations of particular wavelength light directed in a fashion that repels geese while avoiding annoying humans. Embodiments include systems associated with golf course pins and other structures and animal decoys that hide undesired aesthetic appearances of prior art industrial lighting elements. Other embodiments employ adjustable/movable mirror elements used in conjunction with systems powered by solar energy panels positioned below the light source, which can be adjusted in terms of direction, shielding, color, duration, wavelength and pulsation, providing a variety of random patterns so as to avoid habituation by geese.

A broadband ultrasonic transducer device (UTD) is disclosed that utilizes a plurality of narrow-band piezo electric elements grouped into single-frequency sub-arrays to provide a relatively simple, highly-reliable deterrent unit (DU) capable of emitting ultrasonic energy over a wide coverage area and at a sound pressure level that meets or exceeds other DU approaches. In an embodiment, the broadband UTD includes a housing portion configured to couple to a plurality of piezo sub-array plates. Each piezo sub-array plate includes a plurality of pockets or cavities to receive respective narrow-band (e.g., 1-3 kHz) piezo electro transducer elements with characteristics, e.g., geometries and material composition, that cause each to emit ultrasonic energy at a particular resonant frequency. A controller of the UTD implements a control scheme to emit ultrasonic energy in a plurality of output modes including a white noise node and a single-frequency mode for deterrence applications.

An ultrasonic energy gathering device and an ultrasonic repeller using the ultrasonic energy gathering device are provided. The ultrasonic energy gathering device includes an energy gathering part. The energy gathering part has a trapezoidal cross section. The energy gathering part is provided with a gathering port and a diffusing port. The gathering port is smaller than the diffusing port. The ultrasonic energy gathering device further includes an ultrasonic fixing part. The ultrasonic fixing part fixes the ultrasonic energy gathering device with an ultrasonic transmitter of an ultrasonic repeller, so that an ultrasonic wave transmitted from the ultrasonic transmitter enters the gathering port to be gathered and strengthened, and the coverage of the ultrasonic wave gradually expands along the direction away from the diffusing port under the action of the ultrasonic energy gathering device.

In-vehicle transducers (speakers, sound exciters, or vibrating window panels) are used to generate the ultrasonic waves to repel pests, without driving away family pets or exposing nearby people. In one preferred method, a pest deterrent mode is activated in response to a first user command by emitting ultrasonic soundwaves from a transducer driven by an onboard audio system. A region around the vehicle is monitored for human-related activity within the region. The emission of ultrasonic soundwaves is deactivated when the human-related activity is detected. Emission of the ultrasonic soundwaves is resumed when the human-related activity is no longer detected. Then the pest deterrent may be set to a deactivated mode in response to a second user command.

A pest deterrent system is provided. The pest deterrent system includes a sensor module and an actuator module. The sensor module includes a first housing, a sensor, and a controller. The sensor is positioned within the first housing and proximate to the view window such that the sensor is in visual communication with the view window and configured to detect objects outside of the first housing. The controller is positioned within the first housing and is operatively coupled to the sensor. The controller is configured to receive a signal from the sensor, such as an alert that an object is near the sensor module. The actuator module includes a second housing separate from the first housing, an actuator, and a second controller. The second controller configured to receive a signal from the first controller to actuate the actuator in response to the sensor being triggered.
