摘要： Methods and apparatus enable a robotic system to detect and determine the location, orientation, surface contours, and features of an object that are not otherwise accurately known in order to allow the robotic system to accurately place a pulse/echo layer thickness-gauge ultrasonic transducer gauge onto the surface of the object. The robotic system uses one or more distance measurement sensors to determine the position, orientation, local contour, and other features of the surface in relation to the robot. Another method calibrates an inaccurate distance sensor. Yet another method maintains overall system functionality in a system with multiple distance sensors in the event that one or more of the distance sensors fails. The robotic system may also determine when maintenance is required.

摘要： An ultrasonic transducer that includes a delay line, an active piezoelectric element, and interposing metal conductive layer between the delay line and active piezoelectric element. The delay line and active piezoelectric element are joined so that ultrasonic waves may be coupled from the active piezoelectric element into the delay line or from the delay line into the active piezoelectric element. A via is formed, using a milling operation, in the active piezoelectric element to expose the edge of the interposing metal conductive layer between the delay line and active piezoelectric element. A conductive layer makes electrical contact between the interposing metal conductive layer and the surface of the active piezoelectric element to allow an electrical connection to be made from the surface of the active piezoelectric element to the interposing metal conductive layer.

摘要： An ultrasonic transducer includes a delay line substrate, a piezoelectric element, a metal conductive layer between the delay line substrate and the piezoelectric element, and a backing layer applied to the piezoelectric element. The delay line substrate and the piezoelectric element are acoustically joined, configured to couple ultrasonic waves from the piezoelectric element into the delay line substrate or from the delay line substrate into the piezoelectric element. The backing layer includes a metal film, the metal film has a thickness and an acoustic impedance, and the thickness and the acoustic impedance each have value sufficient to provide acoustic damping. The backing layer has a substantially columnar cross-sectional morphology with a substantially granular surface morphology.

摘要： An ultrasonic transducer that includes a delay line, a piezoelectric element, and a metal conductive layer between the delay line and the piezoelectric element. The delay line and the piezoelectric element are acoustically joined with an atomic diffusion bond to facilitate coupling ultrasonic waves from the piezoelectric element into the delay line or from the delay line into the piezoelectric element.
