Abstract
A method of detecting an event in a structure using a device having sensors and at least one actuator includes sending a signal from the at least one actuator encapsulated in the device, returning a reflected wave signal from the event to each of the sensors in the device, determining a respective duration of time for which the signal travels from the event to each of the sensors, and calculating a location of the event by using differences in the respective durations of time for which the signal travels from the event to each of the sensors to determine an angle and a distance at which the event is positioned.
