Abstract: A method for monitoring a servo-control loop (3) of an actuator system (2) for actuating variable-geometry components of a turbojet, said method comprising: an estimation step of estimating a plurality of monitoring parameters from operating data of the servo-control loop (2); an evaluation step of evaluating a plurality of indicators from the monitoring parameters; an evaluation step for evaluating at least one signature matrix, each signature matrix being representative of the values of at least some of the indicators; and a detection and location step of detecting and locating a degradation affecting the servo-control loop as a function of said at least one signature matrix.

Abstract: A process for monitoring a machine including moving pieces, a lubrication system and an electromagnetic sensor fitted with a magnet and two electrodes is disclosed. The sensor is capable of collecting particles present in the lubrication system between the electrodes. The monitoring process includes a step for obtaining measurements of resistance between the electrodes of the sensor, taken during an operating period of the machine; a step for determining from said measurements a first autoregressive mathematical model characterizing the resistance; a step for comparison between the first model and a predetermined reference model; and a step for working out an opinion on maintenance of the machine as a function of the comparison result.

Abstract: The rasp combines a handle (1) and a toothed blade (2) made up of two relatively movable parts (3, 4). The part (4) is moved transversely relative to the part (3) by means of a screw (5), thereby enabling a surgeon to modify the width of the blade (2) so that it matches the width of a prosthesis which is to be put into place.Surgical equipment.

Abstract: A prosthesis kit comprising an elongate prosthesis body (1) and a series of modular strips (2a, 2b, 2c) of different thicknesses which are suitable for being combined with the body to constitute assemblies of different widths (Da, Db, Dc). Each of the modular strips has a longitudinally extending dovetail section edge (e.g., a dovetail tongue 20) which is suitable for interfitting in a complementary dovetail section (e.g., a groove 13) provided on a side of the elongate body, in such a manner that the interfitting dovetail sections ensure that the assembled body and strip are mutually fixed against relative sideways displacement.
