Abstract: A system for monitoring an acoustic scene outside a vehicle; the system including: a vehicle with wheels and a trunk, an acoustic sensor disposed in the trunk, a control unit operatively connected to the acoustic sensor, and at least one neural network operatively connected to the control unit, and trained in such a way to correlate the characteristics of an audio signal with types of road surfaces; the control unit is configured in such a way to receive an audio signal detected by the acoustic sensor while the vehicle is traveling, extract the characteristics of the audio signal and input said characteristics of the audio signal to the neural network in order to identify the type of road surface covered by the vehicle wheels.

Abstract: A container for cosmetic products, fitted with a hollow base body (2), a refill bottle (4) for the cosmetic product packaged in the container (1), a wand (12,12a) for applying the cosmetic product and a lid (3,3a) for closing said bottle (4). In this way, a container structure is obtained for cosmetic products of the modular type with separate elements, mutually coupled when the container is assembled in use and reciprocally separable for the replacement of damaged elements and for the refill of the depleted cosmetic product.

Abstract: A manufacturing method of a microphone is disclosed, wherein a patterned upper electrode is obtained by a first deposition of conductive material in such a way to form pads of the patterned electrode, and pillars are formed by of successive depositions of rigid conductive material, in aligned position on the pads of the patterned electrode. The first deposition and the successive depositions are made by screen-printing, dispenser-printing or spray-coating of material in liquid or semifluid state.
