  • Patent number: 9964525
    Abstract: A monitoring system comprising ultrasound sensors to monitor the structure of a composite material part during production is automatically calibrated using reference sensors mounted on reference blocks and placed in the production environment of the part. The automatic calibration comprises actuating a reference sensor to transmit an ultrasonic wave and measuring the amplitude of a reference echo constituted by the transmitted ultrasonic wave after it has passed through the reference block. The measured amplitude is compared to a set point value and the gain is applied to the reference sensor to obtain an amplitude value of the reference echo substantially equal to the set point value. The gain applied to the reference sensor is applied to the ultrasound sensors of the same type as the reference sensor. The operation is performed for each reference sensor, and successively for all of the stages of production of the part.

  • Patent number: 8960005
    Abstract: Frequency-steerable acoustic transducers (FSATs) that allow directional generation or sensing of waves propagating in two-dimensional domains. Directionality is the result of the spatial filtering effect produced by the characteristic shape of the sensing surface. A wavenumber spiral FSAT (WS-FSAT) maps the direction of wave sensing in the [0°, 180°] range to a specific frequency component in the spectrum of the received signal. The use of a wavenumber spiral FSAT operating in sensing mode can be used for the localization of broadband acoustic events. One configuration includes a broadband source generating guided elastic waves in an isotropic plate. The WS-FSAT records the plate response and defines the source location through a time-frequency analysis of the received signal. The frequency selective response of the WS-FSAT directly maps the dominant component of the received signal to the direction of arrival of the incoming wave, thus greatly facilitating the source localization procedure.

  • Patent number: 8510062
    Abstract: In a method for assessing a condition of at least one value document with regard to limpness, there is determined from transmission values representing the ultrasound transmission at different places on the value document a condition value which depends on a variation of the transmission values and characterizes the condition of the value document with regard to limpness. A condition of the value document is determined for the condition value using a preset criterion.

  • Publication number: 20130160552
    Abstract: It is intended to provide an internal defect inspection method and an apparatus for implementing the method by which an ultrasonic wave is excited in a sample without contact with the sample and accordingly without damaging the sample, and an ultrasonic wave from any internal defect of the sample is detected without being affected by the sample surface, in a non-contact state and with high sensitivity. By the internal defect inspection method, an ultrasonic wave is emitted from an ultrasonic wave transmitter toward a sample, an ultrasonic wave reflected by the sample is detected as an interference signal with an imaging type common-path interferometer, an ultrasonic wave signal is obtained from the interference signal, and any defect within the sample is detected from the ultrasonic wave signal.

  • Patent number: 8371151
    Abstract: The present invention relates to a method of detecting non-linear operation of a measuring device comprising an array of transducers and at least one receiver channel portion. The method comprises receiving measured signals through transducers of the array, processing the measured signals from the transducers through the receiver channel portion, combining the processed measured signals to produce a combined measurement signal, and detecting non-linearity of the combined measurement signal and non-linear operation of the measuring device by detecting saturation of the receiver channel portion. In one embodiment, the receiver channel portion comprises an analog-to-digital converter, a threshold is assigned to a digital output of the analog-to-digital converter, and saturation of the receiver channel portion is detected when the digital output of the analog-to-digital converter oversteps the assigned threshold. In one application of the invention, the measuring device is a non-destructive testing device.
