Patent ID: 6950761

Claim:
A system for wavelet analysis of one or more acoustic signals to identify one or more anomalies in an object, the system comprising: a library of one or more reference wavelet power spectra that each correspond to one or more objects that comprise one or more known anomalies; and an analysis module operable to: receive an acoustic signal from an acoustic scan of an object; calculate a wavelet power spectrum of the acoustic signal; access the library; compare the wavelet power spectrum with one or more reference wavelet power spectra; if the wavelet power spectrum from the acoustic scan corresponds to one or more reference wavelet power spectra, communicate analysis results indicating that the object under analysis comprises one or more particular known anomalies corresponding to the one or more reference wavelet power spectra that correspond to the wavelet power spectrum; and if the wavelet power spectrum does not correspond to one or more reference wavelet power spectra, communicate analysis results indicating that the object under analysis lacks the one or more known anomalies that the one or more reference wavelet power spectra in the library correspond to.
