Patent ID: 8265889

Claim:
A structural health monitoring system, comprising: a structure; and at least one integrated circuit, the at least one integrated circuit configured to transmit interrogating signals to a plurality of actuators coupled to the structure, to receive sensor signals from a plurality of sensors coupled to the structure, and to determine a health of the structure according to a comparison of the received sensor signals to baseline signals; wherein the interrogating signals correspond to stress waves propagated through the structure so as to query the structure; wherein the sensor signals correspond to stress waves detected by the plurality of sensors; wherein the baseline signals correspond to a baseline state of the structure; wherein one or more integrated circuits of the at least one integrated circuit is coupled to the structure, and wherein the at least one integrated circuit includes a first integrated circuit comprising: at least one memory storing baseline signal data corresponding to the baseline signals, and interrogating signal data corresponding to the interrogating signals; and a processing block configured to receive sensor signals and programmed to retrieve the baseline signal data, to compare the sensor signals to the baseline signals according to the retrieved baseline signal data, to output results data resulting from the compare, and to initiate transmission of the interrogating signals for querying the structure.
