    Abstract: A system for detecting vehicle body damage is disclosed. One or more ultrasonic transceivers are installed on a portion of the vehicle body and configured to transmit and receive ultrasonic sound waves. One or more controllers are coupled to the one or more ultrasonic transceivers. The one or more controllers are programmed to cause the ultrasonic transceiver to emit first ultrasonic sound waves and receive first reflected ultrasonic sound waves, store in memory first sound signature data relating to the first reflected ultrasonic sound waves, cause the ultrasonic transceiver to emit second ultrasonic sound waves and receive second ultrasonic sound waves, and determine a presence of damage on the portion of the vehicle body based on second sound signature data relating to the second reflected ultrasonic sound waves deviating from the first sound signature data.

    Abstract: A defect inspection device (100) includes an excitation unit that excites an elastic wave, an irradiation unit (2) that applies laser lights, a measurement unit (3) that measures the interfered laser lights, and a control unit that acquires vibration state information which is information about a state of the elastic wave excited in an inspection target (P) for a plurality of frequencies by changing a frequency of excitation vibration caused by the excitation unit in order to excite the elastic wave in the inspection target (P), and extracts recommended frequencies (F) recommended for inspecting a defect of the inspection target (P) from among the plurality of frequencies based on the acquired vibration state information for the plurality of frequencies.

    Abstract: Devices, systems, methods, and kits of parts for monitoring operation of an electron beam additive manufacturing systems are disclosed. A monitoring system includes one or more measuring devices positioned on the at least one wall in the interior of a build chamber of the additive manufacturing system. Each one of the one or more measuring devices includes a piezoelectric crystal. The monitoring system further includes an analysis component communicatively coupled to the one or more measuring devices. The analysis component is programmed to receive information pertaining to a frequency of oscillation of the piezoelectric crystal. A collection of material on the one or more measuring devices during formation of an article within the build chamber causes a change to the frequency of oscillation of the piezoelectric crystal that is detectable by the analysis component and usable to determine a potential build anomaly of the article.

    Abstract: A vibration test device (100) is a vibration test device for testing vibration of a pipeline (10) attached to a structure. The vibration test device includes a plurality of support members (101a, 101b) that are joined to a wall surface with a predetermined gap therebetween and support the pipeline, a first fixing member (102a) that fastens the pipeline to a first support member at a position where one end of the pipeline protrudes from the first support member, a second fixing member (102b) that fastens the pipeline to a second support member at a position where another end of the pipeline protrudes from the second support member, a vibration-applying portion (103) that applies vibration force to one of the support members, a detection unit (104) that detects vibration of the pipeline, and a measurement unit (105) that measures a vibration characteristic of the pipeline.
