Peaceful Applications
A 1998 patent describes a device that can scare off birds from wind turbines, aircraft, and other sensitive installations by way of microwave energy pulses. Using frequencies from 1 GHz to about 40 GHz, the warning system generates pulses of milliseconds duration, which are claimed to be sensed by the birds' auditory systems. It is believed this may cause them to veer away from the protected object.

Famous quotes containing the word peaceful:
“The industrial world would be a more peaceful place if workers were called in as collaborators in the process of establishing standards and defining shop practices, matters which surely affect their interests and well-being fully as much as they affect those of employers and consumers.”
—Mary Barnett Gilson (1877–?)
