Abstract: A system for measuring cardiac parameters uses a movements sensor to generate a seismocardiographic signal and a cardiac parameters calculation unit. The cardiac parameters calculation unit provides for generating an envelope signal correlated to the seismocardiographic signal; identifies, in the envelope signal, signal segments having a repetitive pattern; identifies, among the signal segments, pairs of successive peaks such that a first peak of each pair of successive peaks is a systolic peak and a second peak of each pair of successive peaks is a diastolic peak; and calculates a systolic period and a diastolic period for each pair of successive peaks.

Abstract: A microfluidic dispenser device of inhalable substances includes a casing, housed in which are a driving circuit and a microfluidic cartridge having a tank that contains a liquid to be delivered. The microfluidic cartridge is provided with at least one nebulizer controlled by the driving device. The nebulizer includes: a substrate; a plurality of chambers formed on the substrate and fluidically coupled to the tank for receiving the liquid to be delivered; and a plurality of heaters, which are formed on the substrate in positions corresponding to respective chambers, are thermally coupled to the respective chambers and are separated from the respective chambers by an insulating layer, and are controlled by the driving device. Each chamber is fluidically connected with the outside by at least one respective nozzle.

Abstract: A valve module includes a semiconductor body, cavities in the semiconductor body separated from each other by a distance, a cantilever structure suspended over each cavity to enable at least partial closing of the cavity, and a piezoelectric actuator for each cantilever structure. The piezoelectric actuator is configured for use to cause a positive bending of the respective cantilever structure and so modulate a rate of air flow through the valve module.
