Abstract: A system is disclosed for detecting and correlating percussive sounds with previously identified spectral signatures of a plurality of events so as to notify a user of an occurrence of a particular event. The system may include a sensor component which includes a piezoelectric transducer at a periphery of the sensor component for coupling with a surface and converting percussive sounds from the surface into an electrical signal. The sensor component may also include a local processor configured to produce a data signal based on the electrical signal, and a communication device for sending the data signal to a remote processor. The system may also include a remote processor configured to receive the data signal and compare the data signal to at least one reference signal, and send a notification to a user based at least in part on the data signal correlating to at least one reference signal.

Abstract: A method for determining the locations of sensor devices in a sensor array in a structure is disclosed. The method may include placing a sensor device at a location. The method may also include receiving, at a mobile device, an identifier of the sensor device. The method may further include determining, by the mobile device, a compass direction and elevation angle from the sensor device to a base station. The method may additionally include determining a distance between the sensor device and the base station. The method may moreover include determining a location of the sensor device based at least in part on the compass direction and the elevation angle from the sensor device to the base station, and the distance between the sensor device and the base station. The method may furthermore include storing the location of the sensor in association with the identifier of the sensor device.
