Patent ID: 8123476

Claim:
A method for operating installations ( 10 ) having at least one component ( 22 ) which endangers flying animals, comprising the steps of: the component assuming a first state which endangers animals to a greater extent and a second state which endangers animals to a lesser extent, monitoring the physical environment around the installation ( 10 ) and around the component ( 22 ) at least in regions by means of a suitable detection device, the detection device producing a signal when a flying animal enters the monitored region, moving the component of the installation from the state which endangers animals to a greater extent to the state which endangers animals to a lesser extent depending on the signal and, later, moving the installation back to the state which endangers animals to a greater extent, depending on: a) the number of animals of a specific type detected per unit time, and/or b) the signal characteristic of the respectively produced signal, and/or c) if none of the animals of the specific type, which were triggers for the component being moved to the less dangerous state, are detected in the monitored region during a predetermined period of time.
