Provided are a quality inspection method and a quality inspection system for unvulcanized rubber material. A final dielectric constant measurement device detects the dielectric constant of a final rubber material in which a compounding agent of predetermined type is mixed with unvulcanized rubber, and a calculator calculates a compounding ratio of the compounding agent to the final rubber material based on the detected dielectric constant, determines whether or not the calculated compounding ratio is in a preset compounding reference range, displays a determination result on a monitor, and adjusts a ratio of the compounding agent fed into an extruder to the unvulcanized rubber such that the calculated compounding ratio is within the compounding reference range.

Structural health monitoring (SHM)/nondestructive evaluation (NDE) exists as a tool in conjunction with manufactured pieces. Presently disclosed subject matter integrates automated video with a structural health monitoring system. In conjunction with bridge monitoring, integration of such two systems automates determination of the effect or correlation of vehicular loading on SHM data from a subject bridge. Such correlations help to understand the sources of structural health monitoring data, particularly acoustic emission data, in bridges and other structures, such as dams and nuclear plants. Automation of the evaluation of bridges and other structures increases accuracy and minimizes risk to workers and the public. Assessing the structural condition of bridges and other structures as presently disclosed also facilitates automated asset management of transportation systems, such as by state departments of transportation and other bridge/structural owners.

Weld seam testing chain for testing a weld seam by means of ultrasound on two plastic tubes welded together at the ends, comprising standard chain links, wherein the standard chain links are hooked together to form the weld seam testing chain, and the chain can be lengthened or shortened individually, a sensor receptacle for accommodating the ultrasonic sensor, and an adjusting unit for the fine adjustment of the weld seam testing chain length, wherein the standard chain links have a hook on one side and a hook receptacle on the opposite side, thereby enabling the individual chain links to be hooked together.

A method for inspecting a weld of plastic pipes by means of a data processing device, comprising: capturing and storing documents; monitoring and recording the installation and the implementation of the weld of the joint; producing a welding report, or adopting a welding report from the welding machine; testing the weld ultrasonically, wherein the test detects and stores the defects that are in the weld; wherein software is used to capture and store the documents, the welding report and the defects, more specifically the data on said defects, wherein an algorithm of the software is used to evaluate the stored documents, reports, defects and data on said defects, and to classify the welded joint as compliant or non-compliant with the requirements.

A supersonic inspection jig has an insertion section 22 inserted into a hole 10 of an inspection target 1, and a flange section 23 connected with the insertion section 22 and contacting the inspection target 1. The flange section 23 has a flange section first surface 231 which is a surface on the side contacting the inspection target 1 and a flange section second surface 232 which is a surface on the side contacting the probe 41. A position limiting section 26 is provided on the flange section second surface 232 to limit the position of the probe 41 so that the probe 41 is maintained in a position separate from a central axis C of the hole 10. Thus, the inspection around the hole becomes easily executable.

A non-destructive inspection judgment system for inspecting a non-destructive inspection subject using ultrasonic waves, including an ultrasonic wave generator transmitting and receiving ultrasonic signals by generating ultrasonic waves to the non-destructive inspection subject placed on an inspection table, an interface transmitting an ultrasonic signal received from the ultrasonic wave generator to an ultrasonic wave generation data controller, the ultrasonic wave generation data controller processing ultrasonic wave data received from the interface, a sealing defect presence judger determining, using the processed ultrasonic wave data, whether a sealing defect is present, and a display displaying a result of the judgment on a monitor to detect an unsealed portion of an aluminum pouch.

Systems and methods are provided for ultrasonic imaging of composite parts. One embodiment is a method that includes providing an object having multiple layers of fibers and resin, inducing ultrasonic waves at locations along the object, and attenuating the ultrasonic waves at the regions due to regions interspersed among the layers that each exhibit an elastic modulus distinct from an elastic modulus of the fibers and distinct from an elastic modulus of the matrix. The method further includes receiving the attenuated ultrasonic waves, and analyzing the attenuated ultrasonic waves to determine depths of the regions.

Embodiments of the present invention provide systems and methods for tagging and acoustically characterizing containers.

The invention comprises a device and method to estimate the elasticity of soft elastic solids from surface wave measurements. The method is non-destructive, reliable and repeatable. The final device is low-cost and portable. It is based in audio-frequency shear wave propagation in elastic soft solids. Within this frequency range, shear wavelength is centimeter sized. Thus, the experimental data is usually collected in the near-field of the source. Therefore, an inversion algorithm taking into account near-field effects was developed for use with the device. Example applications are shown in beef samples, tissue mimicking materials and in vivo skeletal muscle of healthy volunteers
