Penn State Inspirational Quotes

In fact, a dolphin's whistles, pulses, and clicks, made by air sacs just below its blowhole, are among the loudest noised made by marine animals. A scientist at Penn State's Center for Information and Communications Technology Research has been analyzing these underwater messages not for meaning but for hints on how to make our wireless signals more effective. As the Ask Nature database describes, Dr. Mohsen Kavehrad uses "multirate, ultrashort laser pulses, or wavelets, that mimic dolphin chirps, to make optical wireless signals that can better penetrate fog, clouds, and other adverse weather conditions." The multiburst quality of dolphin sounds "increases the chances that a signal will get past obstacles" in the surrounding water. In the same way, Dr. Kavehrad's simulated dolphin chirps increase the odds of getting around such tiny obstacles as droplets of fog or rain. This strategy could expand the capability of optical bandwidth to carry even greater amounts of information. Such an application technology could optimize communication between aircraft and military vehicles, hospital wards, school campus buildings, emergency response teams, and citywide networks.
