EMILY (Emergency Integrated Lifesaving Lanyard) rescue buoy is manufactured by an Arizona base company called Hydronalix.The remote controlled rescue buoy has the capability of 518 minutes of patrol at 5mph.
The first EMILY was built in September 2009, for scientific use by the National Oceanic and Atmospheric Administration (NOAA). Since this March, successive versions have been tried out by lifeguards at numerous Southern California beaches.
EMILY rescue buoy is designed with a JetSki-style impeller that will suck water in from the front side and shoots it out the back. A shore base coast guard could communicate with EMILY using the onboard camera and two-way radio system.
