    摘要: An ultrasonic inspection device is used for inspecting a packaging container having a joined portion including overlapping and joined edges of the packaging container. The ultrasonic inspection device includes a transmitter configured to irradiate ultrasonic waves toward at least a base end portion of the joined portion in a state in which the joined portion protrudes from a surface of an object in a direction orthogonal to the surface, the base end portion being positioned on a side of the object. The ultrasonic inspection device further includes a plurality of receivers configured to receive the ultrasonic waves transmitted through the joined portion.

    摘要: In general, according to one embodiment, a sound inspection apparatus includes: at least three microphones, a removing unit, and an estimation unit; the removing unit calculates an impulse response based on a sound pressure of a radiation sound collected via reference microphone and a first microphone, calculate an impulse response based on the sound pressure of the radiation sound collected via the reference microphone and a second microphone, and remove a component corresponding to the vibration sound from the calculated impulse response; the intensity calculation unit calculates an intensity of the radiation sound based on the impulse response from which the vibration sound is removed; the estimation unit estimates, based on the calculated intensity, a site where an abnormality in the inspection target object has occurred.

    摘要: Various approaches for assessing a part for a defect are disclosed and that are based upon SAW modes. In one embodiment, a part-under-test (120) is excited. One or more SAW modes (206) are identified in the frequency response (240/260) of the part-under-test (120). A SAW mode area (248/266) in the frequency response of the part-under-test (120) is compared with a baseline SAW mode area (238/258) of a baseline frequency response (230/250) (and which may be associated with an acceptable part). This comparison may be used to determine if the part-under-test (120) may be characterized defective in at least some respect.
