Latest Patents

Hildebrand's latest patents include innovative methods for ultrasonic imaging and measuring stress concentrations in objects. One of his patents, titled "Method and apparatus for ultrasonic imaging using a line source," describes an apparatus that utilizes an elongate source of coherent acoustic waves. This source is brought to a line focus and propagated in an object of interest. The acoustic waves are detected by a linear array of point receivers, which are aligned parallel to the source. This setup allows for the sweeping of an area across the object, enabling the detection of amplitude and phase variations in the scattered acoustic waves. The data collected is then digitized and reconstructed to produce a digital image of the object.

Another significant patent is the "Method and apparatus for ultrasonically measuring concentrations of stress in objects of interest." This apparatus employs an ultrasonic transducer array to propagate acoustic waves in various directions and positions within an object. A time interval counter measures the time of flight of these waves, allowing for the reconstruction of a map that illustrates variations in acoustic velocity. This information is then mathematically converted into a map of stress concentration areas within the object.
