Pinpointing origins of gunshots

"Nobody called the cops, nobody dialed 911. But when newly installed technology picked up the sound of gunfire in York, Pa., last month, it quickly directed police to a precise location where they found a 21-year-old man who had been shot three times. He was rushed to a hospital where he recovered from his wounds.

Chalk up another success for ShotSpotter, an unusual, fast-growing Silicon Valley company whose system for pinpointing the origin of gunshots is now getting deployed in cities across America — including neighborhoods in Oakland, San Francisco and East Palo Alto. This technology, first introduced in Redwood City in the mid-1990s but widely adopted only recently, is also being tested by U.S. forces in Iraq."
