Abstract: A microphone unit having only one PCB, a plurality of transducers of acoustic-electric type with digital output mounted on a back side of the PCB, through holes obtained in the PCB in correspondence with each transducer, an A2B audio interface mounted on the back side of the PCB and electrically connected to the transducers; and input/output electrical connectors mounted on the back side of the PCB and electrically connected to said A2B audio interface; the plurality of transducers include a central transducer and at least three peripheral transducers disposed at the same radial distance from the central transducer and equally angularly spaced. A microphone meta-array includes a plurality of microphone units connected by one or more A2b networks.

Abstract: An antenna system for radio mobile communications in vehicles having at least one remote antenna module connected with a cable to a central control unit; the remote antenna module having: a plurality of radiant elements, an RF front end and a control interface; the central control unit having: a signal processor, and a control interface; the control interface of the remote antenna module and the control interface of the central control unit are suitably configured for transmitting the input/output data signals and the control signals over the cable in order to control the control interface and the RF front end of the remote antenna module.

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 manufacturing process of a rear window for vehicles including the following steps: provision of a glass plate with an external side suitable for being directed towards the exterior of the vehicle and an internal side suitable for being directed towards the interior of the vehicle; application of a heater on the internal side of the glass plate, the heater having two bus bars that are electrically connected to a positive pole and to a negative pole of a battery of the vehicle, respectively, and a plurality of horizontal heating lines that connect the bus bars; and application of antenna traces on the internal side of the glass plate, wherein the antenna traces have strips of transparent nanowires made of conductive material. The application of the antenna traces is made by spray-coating on the internal side of the glass plate.

Abstract: A headrest suitable for being fastened to a vehicle seat having: an upper support portion, a reinforcing frame connected to the upper support portion for fastening the upper support portion to the vehicle seat, and an array of microphones comprising microphones disposed inside seats obtained in the headrest, in such a way that the microphones can be used to capture the sounds from the user sitting on the seat where the headrest is connected, as well as environmental microphones to capture the environmental noise perceived around the headrest.
