Abstract: A device for tracking a target component through electrical time-domain or frequency-domain reflectometry has an electromagnetic waveguide and an interrogator electrically connected to the waveguide in order to inject an incident signal therein and receive a reflected signal in response. The reflected signal has a background echo reflected by the exit end of the waveguide. The waveguide has a measuring part with a plurality of base discontinuities, distributed randomly along the measuring part of the waveguide, and that are able to generate echoes having an amplitude greater than 1% and less than 30% of the amplitude of the background echo.

Abstract: A method for detecting a defect in a region of interest within a part to be tested includes the step of, for a reference part identical to the part to be tested but free from defects, determining a set of resonant modes each defining: a resonant frequency of the reference part, considering that the modulus of elasticity of the reference part is constant, and a field of mechanical stresses on and/or in the reference part that are generated when the reference part resonates at the resonant frequency.

Abstract: A device that includes a piece of armor made from a material that has a domain of plastic deformation under bad before breaking and an elastic deformation domain. The plastic deformation domain represents less than 1% of the elastic deformation domain. The device includes a deformation sensor fixed to the piece of armor and configured to deform plastically under the effect of at least a stress applied to the piece of armor and leading to damage of the piece of armor.

Abstract: A non-destructive process of inspecting an object can include positioning a first and second ultrasonic element relative to the body of the object and offsetting the first and second ultrasonic elements in a direction orthogonal to a longitudinal axis of the body. A further process of inspecting an object can include creating a map of the body of the object including at least one anomaly and providing a quality value associated with the body based on evaluation of one or more criteria selected from the group consisting of the type, number, size, shape, position, orientation, edge sharpness, and any combination thereof of the at least one anomaly. An ultrasonic system can include a first and second ultrasonic element and a processing element.

Abstract: The present disclosure relates to devices and methods for determining the density of insulation (e.g., in a cavity). For example, one aspect of the disclosure is a device that includes a probe, an actuator, a sensor, and a control system. The control system is configured to cause the actuator to oscillate the probe. The sensor is configured to generate a signal that represents the density of insulation. Another aspect of the disclosure relates to a method for determining the density of insulation. The method includes placing a probe into contact with the insulation, causing, via an actuator, the probe to oscillate while in contact with the insulation, and generating, via a sensor, a signal that represents the density of insulation.
