Abstract:
A change in a surface of a wall is detected by transmitting a pulse of input ultrasonic vibrations into a proximal surface of the wall and then receiving ultrasonic vibrations from that proximal surface. The received ultrasonic vibrations are compared with a previously detected pulse of output ultrasonic vibrations that have been received from the proximal surface in order to identify, for example, a time of arrival of a current pulse of output ultrasonic vibrations. The time of arrival of this current pulse of output of ultrasonic vibrations may be used to detect a change in the surface of the wall, such as a change in the thickness of the wall. Other embodiments can detect a change in the roughness profile of the wall using changes in the received ultrasonic vibrations other than arrival time.

Claim (Index 20):
A signal processing apparatus for detecting a change in a surface of a wall using a pulse of input ultrasonic vibrations transmitted into a proximal surface of said wall, said pulse of input ultrasonic vibrations propagating through said wall and reflecting from a distal surface of said wall to form a reflected pulse of output ultrasonic vibrations at said proximal surface, said signal processing apparatus comprising:\n processing circuitry configured to correlate a sequence of sample values of said reflected pulse of output ultrasonic vibrations with a sequence of sample values of a previously detected pulse of output ultrasonic vibrations reflected from said distal surface of said wall and received at said proximal surface to detect changes in said surface of said wall, wherein said reflected pulse of output ultrasonic vibrations and said previously detected pulse of output ultrasonic vibrations comprise vibrations reflected from said distal surface of said wall in response to different pulses of input ultrasonic vibrations.
