Abstract: The invention relates to a microelectromechanical system (10) comprising a drive module (200) comprising:



a fixed drive portion (210),
a movable drive portion (220), and
a suspension (230),

the movable drive portion (220) being able to be moved relative to the fixed drive portion (210) in a first direction (A), as a result of an electrostatic force, which causes an elastic deformation of the suspension (230), and the movable drive portion (220) being able to be moved relative to the fixed drive portion (210) in a second direction (B), opposite to the first direction (A), as a result of an elastic return force generated by the suspension (230),

the actuator (11) also comprising a stop (24) limiting the movement of the first movable portion (220) in the second direction (B) so that the elastic force generated by the suspension (230) is not cancelled.

Abstract: The present invention relates to a MEMS deformation sensor for measuring a relative movement between two regions of a structure, the sensor comprising: —a first portion (2) and a second portion (3) that are movable with respect to one another along a direction of measurement (X); —a thrust element (4) mounted fixed with respect to the first portion; —a first electrode (A) and a second electrode (B) that are capable of being raised to different electrical potentials, each mounted fixed with respect to the second portion; —a connecting portion (I) forming an electrical link between the first electrode and the second electrode, the thrust element applying a load to the connecting portion when the first portion moves with respect to the second portion along the direction of measurement beyond a predetermined distance, the electrical link being broken under the effect of the load.

Abstract: Disclosed is a method for counting events occurring during a period T carried out by a mechanical counter including two toothed wheels with the same pitch, the occurrence of an event causing the rotation of each wheel by an angle corresponding to the pitch of the teeth thereof, the method including: counting or calculating, for each wheel at the end of T, the difference in the number of teeth between the initial and final position thereof, the step being at least partially carried out either by an optical unit, requiring the presence on each wheel of at least one marker, or by a unit for measuring the angular displacement of each wheel and associated calculation unit; and calculating the number of occurred events N in accordance with the difference between the values counted or measured and in accordance with the number of teeth of the wheels.
