Abstract: -- A device for generating electric current in a fluid flow circuit, including a duct segment interposed in the fluid flow circuit, a rotor mounted in the duct segment and movable by the passage of a fluid through the device, and a stator or stator circuit cooperating with the rotor and producing electric current. The rotor is made up of a transverse flow turbine, the axis of rotation of which extends across the duct segment, the turbine having at the longitudinal ends of its axis of rotation means for holding against the opposite walls of the duct segment, the stator or stator circuit being positioned outside the duct segment at an end of the turbine which is able to be driven in rotation while the turbine moves, and includes structure for generating a magnetic flux for cooperating with the stator or stator circuit in order to produce the electric current.

Abstract: A disclosed method involves: receiving, by a processing device, a first plurality of photon count values indicating a number of photons detected by an optical system during a plurality of first time periods as a result of laser beam excitation of an observation volume of a sample during fluorescence fluctuation microscopy analysis; calculating, by the processing device based on the first plurality of photon count values, a first count rate per molecule indicating the average number of photons detected per molecule of the observation volume; and generating, by the processing device based on the first count rate per molecule, a control signal for configuring a phase modulation device of the optical system.
