Abstract: Aspects provide for in-situ monitoring of a structure, such as a portion of an in-operation vehicle, by a patch and controller by transmitting, at a first time, a first signal from a first transceiver of a plurality of transceivers in contact with the structure; receiving the first signal carried in the structure at a second transceiver of the plurality of transceivers at a known distance from the first transceiver; determining a baseline signal characteristic of the first signal as received at the second transceiver; transmitting, at a second time, a second signal from the first transceiver; receiving the second signal carried in the structure at the second transceiver; determining a diagnostic signal characteristic of the second signal as received at the second transceiver; and in response to determining that a difference between the baseline signal characteristic and the diagnostic signal characteristic exceeds a threshold, generating an alert.

Abstract: A surface roughness analysis system and methods of analyzing surface roughness of a workpiece are presented. The surface roughness analysis system comprises a number of wave generators; a number of wave sensors; and an ultrasonic analysis system configured to receive material mechanical parameters for a workpiece, determine incident surface wave signal parameters for a source signal to be sent by the number of wave generators, and determine a cut-off wavelength using the material mechanical parameters, wherein the cut-off wavelength is a ratio of surface wavelength over incident wavelength.
