Abstract: Systems and techniques for measuring process characteristics including electrolyte distribution in a battery cell. A non-destructive method for analyzing a battery cell includes determining acoustic features at two or more locations of the battery cell, the acoustic features based on one or more of acoustic signals travelling through at least one or more portions of the battery cell during one or more points in time or responses to the acoustic signals obtained during one or more points in time, wherein the one or more points in time correspond to one or more stages of electrolyte distribution in the battery cell. One or more characteristics of the battery cell are determined based on the acoustic features at the two or more locations of the battery cell.

Abstract: Le document décrit des procédés et des dispositifs pour la détection d'un défaut dans un rail d'une voie ferrée, comprenant: au moins deux capteurs sélectionnés parmi des transducteurs magnéto-acoustique et/ou piézoélectriques et/ou magnétostrictifs; chaque capteur étant associé à un circuit d'horodatage d'un système de positionnement par satellites GNSS; un circuit de mesure pour mesurer par lesdits capteurs les ondes acousto-élastiques se propageant dans le rail, les mesures d'ondes ou signaux étant horodatés. Des développements décrivent notamment des modes actifs et passifs; l'utilisation de passages de trains; l'émission d'ondes; la détermination de l'existence, puis de la position et enfin la caractérisation du défaut le cas échéant; des placements privilégiés pour la pose des capteurs; l'utilisation de procédés d'inter-corrélation, de filtre inverse passif ou de corrélation de coda de corrélation; l'utilisation de robots mobiles et/ou drones; l'utilisation de sources de bruit artificielles.

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. The process element can be configured to create a map of the body including at least one anomaly and provide 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.
