Patent number: 11994496Abstract: An inspection probe and system for inspecting a welded or brazed joint includes a housing having an internal cavity and opposed tapered standoffs disposed at a distal end portion of the housing. Distal ends of the opposed tapered standoffs define pivot surfaces, and the opposed tapered standoffs are spaced apart to define a secondary enclosure. A plurality of transducer elements are disposed within the internal cavity of the housing and a primary coupling medium made of a flexible, semi-solid material is secured between the opposed tapered standoffs. A signal processing module is in communication with a data acquisition unit, which is in communication with the transducer elements. The inspection probe is rotated across the joint, data from the transducer elements is communicated to the signal processing module, and reconstructed and corrected images obtained at different angles from the transducer elements are stitched to generate an inspection image.Type: GrantFiled: May 12, 2021Date of Patent: May 28, 2024Assignees: Ford Global Technologies, LLC, University of WindsorInventors: Bita Ghaffari, Elizabeth Therese Hetrick, Roman Maev, Andrew Ouellette

Patent number: 6657188Abstract: Neutral particles, such as atoms and molecules, transported along a path having at least one curved region are selectively conveyed or filtered according to each particle's velocity by generating an inhomogeneous magnetic field across a cross-section of the path. The neutral particles may be transported through a physical tube or simply through the region defined by the magnetic field. The path may have more than one curved region and may additionally have one or more straight regions. The magnetic field may be generated for example by homogeneously or inhomogeneously magnetized permanent magnets or by current carrying elements. The magnetic elements may additionally be used in conjunction with at least one piece of a high permeability magnetic material for focussing or containing the magnetic field.Type: GrantFiled: August 17, 2000Date of Patent: December 2, 2003Inventors: Randall Gardner Hulet, Kevin Edwin Strecker, Jordan Mitchell Gerton, William Ian McAlexander, Curtis Charles Bradley, Jeffrey J Tollett, Charles Ackley Sackett, Bita Ghaffari, Stephen Calvin Moss
