摘要： Indoors positioning and navigation systems and methods are described herein. In one embodiment, a system for inspecting or maintaining a storage tank includes a vehicle having: at least one sensor for determining properties of a storage tank and a navigation system. The navigation system includes an acoustic transmitter carried by the vehicle and an inertial measurement unit (IMU) sensor configured to at least partially determine a location of the vehicle with respect to the storage tank. The vehicle also includes a propulsion unit configured to move the vehicle within the storage tank, and an acoustic receiver fixed with respect to the storage tank. The vehicle moves inside the storage tank in concentric arcs with respect to the acoustic receiver.

摘要： Operating parameters are selected for inspecting a structure. Selecting the operating parameters includes exciting broadband ultrasonic guided waves in a multilayered structure, acquiring data corresponding to the sensed broadband ultrasonic guided waves in the multilayered structure, selecting one or more narrow frequency bands based on the acquired data, and inspecting the multilayered structure using ultrasonic guided waves in the one or more narrow frequency bands. In some examples, the data is acquired by an inspection tool capable of sensing the broadband ultrasonic guided waves in the multilayered structure.

摘要： Systems and methods for detecting corrosion in pipes are disclosed herein. In one embodiment, an apparatus for detecting corrosion in an object includes an electromagnetic acoustic transducer (EMAT) having a ferromagnetic core and a plurality of permanent magnets arranged peripherally around the ferromagnetic core. The permanent magnets are arranged to produce a magnetic field through the ferromagnetic core. The apparatus also includes a coil between the ferromagnetic core and the object.

摘要： Systems and methods for inspection of pipelines are disclosed herein. In one embodiment, an electromagnetic acoustic transducer (EMAT) transceiver (TRX) for inspecting a pipe includes a multichannel EMAT transmitter (TX) having multiple collocated transmitter coils. The EMAT TX can generate forward-propagating ultrasound waves and backward-propagating ultrasound waves. The forward-propagating ultrasound waves have higher amplitude than the backward-propagating ultrasound waves. The EMAT TRX also includes a multichannel EMAT receiver (RX) having multiple receiver coils that can receive the ultrasound waves transmitted by the EMAT TX through the pipe.
