摘要： Thermal Acoustic Imaging (TAI) methods and systems are provided for detecting defects in an object. The TAI system may include a plurality of acoustic wave transceivers (AWTs), which are positioned around the object at different locations, and a broadband frequency signal generator, which is coupled to each of the AWTs. The system may further include an acoustic processor configured to utilize the AWTs to gather acoustic data pertaining to the object, process the acoustic data to generate spectral response data, and then process the spectral response data to determine an optimized setup. The optimized setup may include optimized excitation frequencies and optimized inspection positions for positioning a plurality of infrared imaging devices at different locations around the object. A plurality of infrared imaging devices may then be selectively positioned with respect to the object at the optimized inspection positions and utilized to further inspect the object for defects.

摘要： A method and apparatus is provided to analyze a dual wall structure having at least one hollow core therein and having the same unknown material sound velocities in walls and in post as well. A transducer is located in at least two different positions with respect to the structure, whereby the transducer propagates an ultrasonic wave toward the dual wall structure. A portion of the ultrasonic wave is reflected back to the transducer. One wave traverses a portion of the dual wall structure that has a core filled with a medium having a known material acoustic property. A second wave traverses a portion of the post that has an unknown material sound velocity. From time of flight measurements of the above mentioned waves, the wall thickness and core shift, if any, can be determined.

摘要： This invention provides a convenient method for converting oximes into enamides. The process does not require the use of metallic reagents. Accordingly, it produces the desired compounds without the concomitant production of a large volume of metallic waste. The enamides are useful precursors to amides and amines. The invention provides a process to convert a prochiral enamide into the corresponding chiral amide. In an exemplary process, a chiral amino center is introduced during hydrogenation through the use of a chiral hydrogenation catalyst. In selected embodiments, the invention provides methods of preparing amides and amines that include the 1,2,3,4-tetrahydro-N-alkyl-1-naphthalenamine or 1,2,3,4-tetrahydro-1-naphthalenamine substructure.
