Abstract: An apparatus for measuring, viscosity or one or more rheological properties of fluids as a function of at least one signal, said apparatus comprising: at least a member with at least an Inertial Measurement Unit coupled to said member, said Inertial Measurement Unit configured to measure said at least one signal in relation to said member; and at least a motor coupled to said member in order to make said member into a vibrating member, upon actuation of said coupled motor, said member being configured to be dipped into a fluid whose viscosity or one or more rheological properties is to be measured.

Abstract: Methods and systems for processing data to distinguish between a plurality of conditions in lung ultrasound images and, in particular, lung ultrasound images containing B lines. Neural network systems and methods, in which the processor is trained using lung ultrasound images to distinguish between acute respiratory distress syndrome due to COVID-19, acute respiratory distress syndrome due to non-COVID-19 causes, and hydrostatic pulmonary edema.
