A newly discovered patent from Apple describes a system for generating an alert based on calendar events and GPS location information. The system would expand the normal preset, time-based alert system with one that dynamically uses your location. The system would tie your GPS location to your calendar entires and remind you when you are near an event or pull up directions to your meeting or event. It could also use weather information, traffic data, public transportation schedules and more to help get you where you need to go. The patent was filed in 2009 and was only recently made public by the USPTO.
