Abstract: Ballistic laminate for implementing a ballistic structure comprising at least two textile layers placed one on top of the other and joined together. The layers (elements) comprise at least a first textile element, of which the ballistic warp threads, having a count higher than 40 dtex, intersect non-ballistic weft threads, having a count less than 40 dtex, and at least a second textile element, in which non-ballistic warp threads, having a count less than 40 dtex, intersect ballistic weft threads having a count higher than 40 dtex. These at least two elements are joined together using various technologies to obtain a stable structure in which the energy absorption in the face of projectiles is greater than the energy absorption for conventional warp-weft fabrics for the same weight per square meter.

Abstract: Measuring assembly with a measuring apparatus and a recognition system, and recognition method to detect the correct positioning of a removable device such as a comparator to check the shape and/or dimensions of a mechanical part with respect to a stationary part that includes at least one mechanical reference for the removable device. The system comprises a field source disposed in the stationary part that generates a field and a matching element disposed on the removable device that is able to alter the propagation of this field if correctly positioned relative to the field source. A sensor fixed to the stationary part in an appropriate position detects or not the field and generates a resulting detection signal detection or non-detection signal. A processing unit receives the signal generated by the sensor and on the basis of this provides information about the correct or incorrect positioning of the removable device with respect to the stationary part.
