pinger
 v.— «As searchers continue to comb thousands of square miles of ocean for debris from Air France Flight 447, their success could hinge on a device the size of a small flashlight that may well have been manufactured on Cape Cod. French authorities have deployed a submarine that will try to locate the plane’s data and voice recorders—the so-called “black boxes”—by detecting signals emitted by the underwater locator beacons attached to them. These beacons, more commonly known as “pingers,” are produced by only a few certified companies worldwide, including Teledyne Benthos in North Falmouth.» —“‘Pinger’ has key role in search for airliner” by Sarah Shemkus Cape Code Times (Hyannis, Massachusetts) June 6, 2009.
