Automatic external defibrillators (AED's) are becoming more common in public places like airports, theaters, and sports stadiums. To be effective, you must quickly find the nearest AED while in an unfamiliar environment, a task that's not immediately obvious when seconds count. Bertalan Meskó at ScienceRoll is reporting that Lucien Engelen, a technologist at the Radboud University Nijmegen Medical Centre in Holland, has a project to geolocate AEDs, and make the data available for mobile browsers. Additionally, you can use a location aware application like the Layar Reality Browser to pinpoint immediately where the AED is located in your vicinity.
