Method and apparatus for converting a displacement of a magnetic object into a directly perceptible signal, instrument incorporating this apparatus

摘要

This method of converting a displacement of a magnetic object into a signal directly perceptible by a human being, comprises: —the acquisition (32) of a temporal succession of measurements of a magnetic field modified by the displacements of the object during a sliding time window of predetermined duration, —the construction (34) on the basis of this acquired temporal succession of measurements of several signals each representing a characteristic of the measured magnetic field dependent on a corresponding characteristic of the displacement of the object, and —the adjustment (50) of several parameters of the directly perceptible signal as a function of the signals so as to render these characteristics directly perceptible.

1. A method for converting a movement of a magnetic object relative to a magnetic field sensor into a signal directly perceptible to a human being, said method comprising: measuring, using the magnetic field sensor, one component of a magnetic field modified as a result of movement of the magnetic object, acquiring a temporal succession of measurements of the one component of the magnetic field during a sliding time window of predetermined duration, building, from the acquired temporal succession of measurements of the one component of the magnetic field, a first set of several signals, the first set of said several signals representing a characteristic of the measured one component of the magnetic field that is based on a corresponding characteristic of the movement of the magnetic object, and setting several parameters of the directly perceptible signal based on the first set of several signals to render the characteristics directly perceptible.
