  • Patent number: 10983092
    Abstract: An acoustic sensor comprises a side wall closed at each end by an end wall to form a cavity which, in use, contains a fluid. At least one transmitter and at least one receiver are operatively associated with one of the end walls. A maximum half width, a, of the cavity and a height, h, of the cavity satisfies the following inequality: a/h is greater than 1.2. In use, the transmitter causes oscillatory motion of the region of the end wall operatively associated with the transmitter, in a direction substantially perpendicular to the plane of the end walls such that the perpendicular oscillations of the end walls drive substantially in-plane oscillations of the fluid pressure in the cavity. The substantially in-plane oscillations in the pressure of the fluid drive substantially perpendicular oscillatory motion of the region of the end wall operatively associated with the receiver, resulting in an electrical signal from the receiver.

  • Patent number: 10955328
    Abstract: A method of integrity testing porous materials that is non-destructive to the material being tested. The inlet gas stream includes at least two gases, wherein one of the gases has a different permeability in liquid than the other, such as oxygen and nitrogen in water. The relative permeability of the gases is measured in the retentate stream, thereby avoiding accessing the permeate stream and potentially introducing contaminants to the material being tested. The integrity test is capable of detecting the presence of oversized pores or defects that can compromise the retention capability of the porous material.
