ABSTRACT:
The internal pressure of a sealed container is characterized by tapping to vibrate a wall of the container, and then basing the characterization of the internal pressure on a frequency spectrum of the vibration and stored data measured from vibrating other sealed containers. The stored data is generated by vibrating a series of tests controllers having different, known internal pressures.
