An inspection apparatus inspects a pressure vessel using laser ultrasound. The apparatus includes an oscillation device that oscillates an excitation laser for exciting the pressure vessel and a conduit to guide the excitation laser oscillated from the oscillation device to inside the pressure vessel. The conduit is inserted into the pressure vessel with one conduit end located inside the pressure vessel and an opposite end located outside the pressure vessel. The apparatus includes a reflector at one conduit end inside the pressure vessel to reflect the excitation laser guided by the conduit and a detector that detects ultrasonic waves generated in the pressure vessel by the excitation laser reflected by the reflector by oscillating a receiving laser from outside of the pressure vessel. At least the conduit, reflector, or detector moves to correct an optical path of the excitation laser or the receiving laser.

An ultrasonic testing inspection scanner is provided for scanning a pipe. The inspection scanner may comprise a frame assembly having a first frame section and a second frame section coupled together, wherein the frame assembly is configured to be positioned between an open position to allow the frame assembly to be placed on the pipe and a closed position where the frame assembly is mounted on the pipe with the frame assembly extending around a circumference of the pipe. Additionally, the inspection scanner may comprise a first probe carrier and a second probe carrier, each having an elongated shape with first and second attachment ends as well as first and second extended ends, respectively. A first probe apparatus may be coupled to the first probe carrier and a second probe apparatus may be coupled to the second probe carrier in an orientation which facilitates testing of the pipe in obstructed or difficult to reach areas.

A sensor system includes one or more sensors that sense vibrations of a vehicle and one or more processors that can determine a speed of the vehicle and determine whether the vibrations occurring at one or more frequencies of interest (that are based on the speed of the vehicle) indicate damage to a propulsion system of the vehicle. The one or more processors optionally may determine a hunting frequency of a wheel and axle set and/or a lateral acceleration of the wheel and axle set from the vibrations. The one or more processors can determine a conicity of a wheel in the wheel and axle set based on the hunting frequency and/or the lateral acceleration that is determined.

Methods, systems, and apparatuses are provided for detecting and determining conditions of and conditions within a fluid conduit.

An apparatus used to balance bullion for a Ping Test. The apparatus is placed on a flat surface. The bullion being tested is then placed in a balanced position on top of the device. The user then taps the now balancing bullion with an appropriate object. This causes a vibration to move through the bullion, which creates a sound that is unique to the physical properties of the bullion being tested. By listening to the sound, and comparing it with a known authentic, the user can determine if the bullion being tested sounds genuine, has anomalies, been altered, tampered with, or is a counterfeit. Any differences in the sound produced is a strong indication that the bullion needs further testing.

The present disclosure enables apparatus and methods for tracking medications and/or product units via smart-packaging concepts. Embodiments include sensors that monitor the state of a blister-card package having an unpatterned lidding film by measuring the impedance of each dispensing region of the lidding film that defines a portion of a blister. In some embodiments, the impedance is measured via a plurality of contact points arranged on opposite sides of each dispensing region, where the contact points are resistively or capacitively coupled with the lidding film. In some embodiments, the impedance map of a measurement region on the blister card is derived via electrical impedance tomography or electrical resistance tomography, where the measurement region includes a plurality of dispensing regions.
