Abstract
Apparatus is provided comprising a signal processor that receives signaling containing information about an acoustic signal swept and sensed over a frequency range in relation to a pipe; and determines information about the structure of the pipe based at least partly on two or more sub-frequency ranges that form part of the frequency range in the signaling received. The signal processor also receives the acoustic signal being transmitted to the pipe and corresponding signaling in the two or more sub-frequency ranges containing information about reflections of the acoustic signal back from the pipe; and determines information about the structure of the pipe based at least partly on a coherent mixing of the acoustic signal and the corresponding signaling in the two or more sub-frequency ranges using a coherent acoustic tomography technique. Alternatively, the signal processor also receives associated signaling in the two or more sub-frequency ranges containing information about associated resonance in a liner of a wall of the pipe and determines information about the liner of the wall of the pipe, based at least partly on the two or more sub-frequency ranges.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
