device for automated and intelligent defence of vertebrates and insects.

摘要

The device has a unit for the detection of acoustic signals (1,2) and for their processing (3) combined with an ultrasonics (5) and/or sound generator (6). When the specific animal approaches the area to be avoided, a central control unit (10,11) will decide about the adequate reaction. The sound of a particular animal or a car is simulated to scare off the approaching animal. To scare off insects or bats ultrasonics can be generated.
