Abstract: A device for analyzing at least one parameter of a chemical or biochemical or biological reaction in a reaction container, the analysis device includes an arm intended to be fastened by means of a sliding link against a face of a wall of the reaction container by means of a static end, the arm having a degree of freedom in translation in relation to the wall, a sensor designed to measure the at least one parameter, the sensor being fastened to a free end of the arm, a drive device designed to cause an axial displacement of the arm along the degree of freedom, a hermetic isolating device for isolating the arm from the reaction, the hermetic isolating device joining the arm to the face of the wall.

Abstract: The invention relates to a system for recording a track comprising: a utensil comprising a tip and equipped with a magnetic object; a device for locating the magnetic object configured to determine an estimated reference position on a writing surface; and a matrix-array touch sensor configured to define a set of M pixels, among N pixels, at least partially encircling the estimated reference position, and to detect the contact of the tip on the writing surface on the basis of the electrical signals generated by said set of M pixels.

Abstract: A kit, for analyzing and monitoring a parameter of a reaction in a reaction chamber, includes: a hollow tube fastened by its ends to the reaction chamber; and a capsule provided with a sensor and guided along the hollow tube via a magnetized magnetic piston disposed in the hollow tube and controlled by a guide device. The hollow tube imposes a predetermined trajectory on the capsule to maintain the capsule at a distance from any mobile member to prevent the capsule from damage. The hollow tube can extend over the entire depth of the reaction medium to allow measurements over the entire depth of the medium.

Abstract: The invention relates to field of connected sport and specifically a method for quantifying sporting activity implemented by a communication system including: a proximity beacon associated with sports equipment, measuring equipment and a communication node, the method including: (a) communicating between the measuring equipment and the beacon in order to recover a first data packet comprising an identifier relating to a sporting activity associated with the sports equipment; (b) transmitting, to the node, a second data packet comprising the identifier; (c) at the node, determining parameterisation data of the measuring equipment according to the identifier; (d) transmitting, to the measuring equipment, a third data packet 230 comprising said parameterisation data; and (e) at the parameterised measuring equipment, quantifying the sporting activity.

Abstract: A method of detecting a predetermined specific value of the charge contained in a first elementary cell of a battery, including the steps of: measuring the voltage across the cell under reference current at a plurality of times in a phase of cell charge or discharge between first and second state-of-charge levels; and detecting a predetermined specific value of this voltage, corresponding to the specific charge value.
