A system for analysis of the performance in use of a sliding board includes a database storing baseline performance; a sensor sensitive to the deformations of said sliding board; and a monitoring body. The monitoring body determines the performance in use based on measurements from the sensor; and compares the performance in use with the baseline performance. The sensor is secured to the sliding board and has at least one piezoelectric element secured to the sliding board and configured to generate electric energy during the deformations of the sliding board; and an electronic processing circuit, powered exclusively by the electric energy generated by the at least one piezoelectric element.

A method for automatic recognition of a predetermined move of a user includes the construction of several characteristic physical quantities of the move of the user from acquired measurements performed by a tri-axial accelerometer only within a time interval [t; t], where the instant tis an instant, later than the instant t, at which the measured acceleration of a fist of the user in a direction Xchanges sign and becomes negative, the direction Xbeing the direction parallel to a forearm of the user, directed from the elbow of the user to the fist of the user, then the classification of the move of the user in a predefined move category, chosen from among several possible predefined categories of moves, from these constructed characteristic physical quantities.

A method and a device for determining a concentration of lipids in a microorganism such as a micro-alga by illuminating a sample containing microorganisms and acquiring a total diffraction pattern of the sample is acquired, the total diffraction pattern including a plurality of unit diffraction pattern each associated with a microorganism.

A method for producing a modulated optical signal from a droplet of a liquid medium. The method positions a droplet of liquid on a hydrophobic surface, in the path of an optical beam, and modulates the shape of the droplet on this surface, by electrowetting, to modulate the signal obtained after passing the optical beam through the droplet.
