  • Patent number: 11906468
    Abstract: An acoustic inspection system can be used to generate a surface profile of a component under inspection, and then can be used to perform the inspection on the component. The acoustic inspection system can obtain acoustic imaging data, e.g., FMC data, of the component. Then, the acoustic inspection system can apply a previously trained machine learning model to an encoded acoustic image, such as a TFM image, to generate a representation of the profile of one or more surfaces of the component. In this manner, no additional equipment is needed, which is more convenient and efficient than implementations that utilize additional components that are external to the acoustic inspection system.

The transducer housing assembly features a lens housing with an opening that is sealed with a replaceable fluid-tight membrane defining an acoustic window with acoustic properties similar to those of fluid in the housing and therefore at least translucent to the transducer and causing minimal signal loss. The housing contains minimal fluid to be cleaned up in case of improper use or leakage. The transducer housing also includes an optional surface offset and an ability to adjust the focal point of the transducer relative to the component surface.

  • Patent number: 11846566
    Abstract: Integrity of a flexible bag is verified by a testing system, using helium to detect existence of a possible hole. The flexible bag is preliminary placed in vacuum chamber of a fluid-tightly isolated enclosure. After connecting a port of the bag to a helium feeding pipe, vacuum suction is performed to obtain vacuum outside the bag in the enclosure. Then, a first amount of helium is diffused in the internal volume of the enclosure through a gas permeable wall, to increase helium partial pressure outside the flexible bag. After, in a test phase while said vacuum suction is still performed, the bag is filled with a second amount of helium. A detector detects information representative of helium partial pressure in the internal volume, to allow detection of helium escaping from the bag, by analysis of a helium partial pressure drop.
