摘要: A method for detecting the presence and/or determine a position of an object on a measurement surface of an electronic device. The process includes: providing oscillating signal(s) at input points which are different and spaced from the array of electrodes in a detection area of the measurement surface; receiving oscillating signal(s) having passed through the array, which defines a transfer function of the signals, in output point(s) which are different and spaced from the array of electrodes in a detection area of the measurement surface; measuring a coupling or an attenuation induced by the presence on one or more oscillating signals passing through the array of electrodes of an object placed on the measurement surface in order to determine the position of the object in the detection area of the measurement surface depending on the modification of the transfer function of the array of electrodes.

摘要: A method for manufacturing an austenitic stainless steel workpiece including the following successive steps: 1) providing a powder and sintering the powder to form a sintered alloy with an austenitic structure; the alloy having a nitrogen content greater than or equal to 0.1% by weight, 2) treating the sintered alloy to transform the austenitic structure into a ferritic structure or ferrite+ austenite two-phase structure on a surface layer of the alloy, 3) treating the sintered alloy to transform the ferritic or ferrite+ austenite two-phase structure obtained in step 2) into an austenitic structure and, after cooling, forming the workpiece which, on the layer subjected to the transformations in steps 2) and 3), has a density higher than that of the core of the workpiece. The present description also relates to the workpiece obtained by the method which has a very dense surface layer (≥99%).

摘要: A method for determining an error in the angular position measurement of a timepiece motor having one or more phases, including: detecting (3) each instant (14) when the value of one of the back electromotive forces is zero, storing (4) a time corresponding to each detected instant, measuring (5) several time intervals between two instants (14) detected in the same revolution of the motor, comparing (6) the measured time intervals to reference time intervals to deduce the reference intervals to which they correspond, and determining (7) an angular position measurement error if the measured intervals do not correspond to the expected reference intervals. The invention also relates to a method for correcting the angular position measurement. Also, a determination and correction system for implementing the methods and a timepiece including such a system.
