摘要
A method of detecting at least a partial blockage in a porous member separating a first volume from a second volume or inner chamber of a device includes emitting pressure waves within the inner chamber by changing a volume of the inner chamber, measuring a response via a pressure sensor responsive to pressure waves positioned within the inner chamber, and determining if at least a partial blockage is present in the porous member based upon the response of the pressure sensor.
