Abstract: A device and method used to image conduits, such as pipes, wellbores and tubulars, with imaging sensors, such as cameras and ultrasound arrays. The speed and location of the device are determined using one or more speed sensor modules. Images are then registered to more precise axial locations along the conduit than are normally possible using wireline encoders or other methods. The conduit may be visualized to proper scale for improved analysis of defects.

Abstract: An acoustic transducer array and method of making same. A first metal layer is deposited on a first side of a piezoelectric composite to form a common electrode and a second metal layer is provided over the obverse side. Portions of the second metal layer are removed to create a plurality of individual electrodes. A third metal layer may be deposited onto the plurality of individual electrodes, the third metal layer being thicker than the second metal layer. The individual electrodes extend beyond the piezoelectric composite in the elevation direction to create electrode leads. Metal layers may be provided by lithography, a wireframe or a foil sheet.
