Abstract: System and method for enabling ultrasonic inspection of a variable and irregular shape. The system comprises one or more ultrasonic pulser/receivers, one or more ultrasonic transducer arrays, a shoe or jig to hold and position the array(s), data acquisition software to drive the array(s), and data analysis software to select a respective best return signal for each pixel to be displayed. This system starts with information about the general orientation of the array relative to the part and a general predicted part shape. More specific orientation of the transmitted ultrasound beams relative to the part surface is done electronically by phasing the elements in the array(s) to cover the expected (i.e., predicted) surface as well as the full range of part surface variability.

Abstract: A vehicle is described herein that includes a unibody vehicle frame, a vehicle body panel, and one or more monolithic tripartite support mechanisms, which mechanisms provide structural support for at least three frame-mounted vehicle components. Each support mechanism includes a windshield support arm, a side view mirror support arm, and a body panel fixing plate. The side view mirror support arm extends from the windshield support, and the body panel fixing plate extends from the windshield support arm, the side-view mirror support arm, or both. Additionally, the windshield support arm holds a windshield to the vehicle, the side view mirror support arm holds a side view mirror to the vehicle, and the fixing plate secures the body panel to the frame.
