Abstract: A system for inspection includes an ultrasound transmitter, an ultrasound receiver, an isolator, and a control system. The ultrasound transmitter, the ultrasound receiver, and the isolator are coupled to an exterior of a metal pipeline. The control system is configured to provide an input signal to the ultrasound transmitter; receive a received signal using the ultrasound receiver; and provide a result based at least in part on the received signal.

Abstract: A sensor includes electrodes and two enclosure portions. The electrodes have a shape to match an outer periphery of a non-metallic parent pipe. The two enclosure portions are connected by a hinge to facilitate positioning around the outer periphery of the non-metallic parent pipe. A first portion of the two enclosure portions includes a cutout electrode for surrounding a cutout space. The cutout electrode is tied to a ground to shield against signals from the cutout space. The sensor generates a signal indicative of the presence or absence of a pipe inserted within an inner periphery of the non-metallic parent pipe based on a capacitance measurement and a threshold.

Abstract: A system for insert detection includes a sensor and a processor. The processor is configured to receive capacitance measurement associated with the sensor and determine presence or absence of an insert based at least in part on the capacitance measurement and a threshold.

Abstract: A system for determining a material property is disclosed. In some embodiments, a method for determining a material property comprises receiving a set of material responses corresponding to a set of ultrasonic excitations. The set of material responses are determined using measurements to determine a peak response for each of the set of ultrasonic excitations. In some embodiments, a device for making non-destructive in-situ measurements of the elastic yield strength of a sample (e.g., a steel plate or pipeline wall) is disclosed. The device determines the yield strength of a specimen based on transducing ultrasonic waves within the medium and correlating quantifiable characteristics of the resulting frequency response to the intrinsic elastic nonlinearity of the material. In various embodiments, the device includes one or more electrodes, an acoustic termination, a horn, a flange, a collar, power electronics, signal processors, a memory, a user interface, or any other appropriate device component.
