  • Patent number: 12281967
    Abstract: A method for detecting a defect in a structure of a device includes generating, only using the device, a low-frequency signal that makes the structure vibrate, generating a high-frequency signal in the structure, and measuring a vibratory signal caused by the generated low-frequency and high-frequency signals at the same time then adaptively re-sampling these measurements to obtain a re-sampled vibratory signal the power spectrum. The resampling includes a first frequency range [uBFmin; uBFmax] of width larger than 5 Hz that contains 95% of the power of the low-frequency signal, a second frequency range [uHFmin; uHFmax] of width systematically smaller than uBFmin that contains 95% of the power of the low-frequency signal. A defect is signaled in the structure if an additional power lobe is detected outside of the ranges [uBFmin; uBFmax] and [uHFmin; uHFmax].
