摘要:
The invention concerns a method whereby a solid mobile in a medium capable of generating disturbances defined by a three-variable vector, wherein the movement is defined by a six-variable vector and the solid is equipped with at least one sensor sensitive to acceleration having at least three sensitive axes and at least one sensor sensitive to the magnetic field having at least three sensitive axes. The inventive method for estimating the movement of a solid includes a step (B6) of calculating a nine-variable vector (Μ) consisting of six-variable movement vector and of the three-variable disturbance vector and a step of weighting (B6) the nine-variable vector (Μ) capable of transforming the nine-variable vector into a vector with not more than five variables to be estimated.

A method for controlling an electronic circuit, characterised in that it comprises a step of feedback control of a current voltage-frequency operating point relative to a reference curve of a voltage-frequency domain of operation associated with the circuit, to bring the circuit from a first operating point to a second operating point, said reference curve linking said first and second operating points in an optimal trajectory relative to a boundary of said domain.

This method of identifying a subset of measurements comprising a measurement disturbed by a magnetic disturber, comprises: a) the emission of magnetic fields and the measurement (70) of these magnetic fields with the aid of N monoaxial source/monoaxial transducer pairs so as to obtain a set of N real measurements; b) the construction (72) of an estimation Pi of the position of an object on the basis of a subset Mi of the N measurements; c) the estimation (74) of N measurements on the basis of an estimated position Pi and of at least one direct model relating the position of the object to the set of N measurements, and d) the determination (76) of whether this subset Mi of measurements comprises a disturbed measurement or not by comparing the measurements estimated during step c) with the real measurements obtained during step a).

The invention relates to a method for determining the values of parameters representative of a movement of an entity represented by an articulated line, using a sensor unit comprising at least one sensor for sensing a parameter representative of an orientation of a first segment of the articulated line, which comprises the following steps: receiving an orientation value measured and supplied by the orientation sensor; and estimating a value of at least one first parameter representative of a movement of the first segment by processing the supplied attitude value. The method further comprises the following step, carried out on the basis of a predetermined motion model of the articulated line, referred to as time variation model, comprising at least one time-dependent relationship between said at least one first parameter and at least one other parameter representative of a movement of another segment of the articulated line: estimating a value of said at least one other parameter by applying the time variation model to the estimated value of said at least one parameter.
