Provided are a method for testing a secondary battery, which include applying laser to the secondary battery after a manufacturing process is completed to generate an ultrasonic signal, detecting the ultrasonic signal, converting the detected ultrasonic signal to generate a digital signal, and processing and analyzing the digital signal, and a method for manufacturing the secondary battery.

In a method for performing ultrasound tests which uses a suitable device for performing such tests, a well plate implements an insulation between the different wells of the well plate of such set, without significant ultrasound transmissions in the plate material, wherein a filling material of the accessible spaces outside the wells is provided which do not reflect nor transmit waves in an extent higher than +/−10%.

A method for dynamically acquiring data representing a part to be tested, the method includes a multi-element sensor acquiring data concerning the part to be tested, transmitting an ultrasonic shot, receiving a returned wave returned by the part resulting from the ultrasonic shot, generating data representing the part to be tested, and during the data acquisition step, a relative movement between the sensor and the part to be tested, the method further includes generating corrected data representing the part to be tested by simulating a relative movement between the sensor and the part to be tested up to a reference position.

Systems and methods are provided for inspecting a wing panel. Some methods include advancing a wing panel through a Non-Destructive Inspection (NDI) station, and inspecting the wing panel with inspection heads at the NDI station. The wing panel may be suspended beneath a strongback during inspection and/or advancement, such as by using vacuum couplers and/or adjustable-length pogos of the strongback, and suspending may include enforcing a contour to the wing panel using the vacuum couplers and/or pogos. Other methods include receiving a wing panel at an NDI station and inspecting a portion thereof during movement through the NDI station. Some systems include a track, a strongback to suspend a wing panel beneath it and to advance along the track, and an NDI station disposed at the track to inspect the wing panel while suspended.

Systems and methods are provided for inspecting aircraft fuselages. Non-Destructive Inspection (NDI) stations inspect sections of a fuselage via pulsed-line assembly techniques. After each pulse, a section of fuselage is moved by less than its length, and one or more NDI stations disposed at different portions of the section to inspect the section of fuselage for out-of-tolerance conditions. A method for inspecting a structure for inconsistencies which includes advancing a structure along a track in a process direction through a Non-Destructive Inspection (NDI) station, indexing the structure to the NDI station and inspecting the structure with the NDI station.

A system for non-destructively inspecting tubes is provided. The system may include a tank filled with a fluid, e.g., water. The tank may define an axial passage within it for tube insertion, and the tank may include an opening to the axial passage. A transducer probe may be disposed inside the tank and oriented toward the opening to the axial passage. The system may also include a movable seal including a chamber, configured to move axially in the axial passage, and a membrane positioned in the opening of the tank. During inspection, an acoustic pathway may be provided between the transducer probe and the tube, the pathway including fluid in the tank, the membrane, and fluid in the chamber.
