Patent ID: 8611188

Claim:
A method for locating at least one object, the method comprising: receiving, by a microphone device of the at least one object, at least one acoustic signal from at least one acoustic source; automatically searching, by a data processing device, a temporal profile of the at least one acoustic signal based on pre-defined criteria to determine at least one pattern of the at least one acoustic signal, wherein the at least one pattern comprises an onset of the at least one acoustic signal, and the onset comprises a sound, a noise, a sound pattern and/or a noise pattern stemming from a surrounding environment of the at least one object; and determining, by the data processing device, a location of the at least one object based on a comparison of the at least one pattern to at least one further pattern determined at at least one further object receiving the at least one acoustic signal, wherein the at least one object and the at least one further object have a time synchronization which is independent of the acoustic signal.
