In an electronic device for counting the number of rotations for a tire and wheel assembly, a storage means holds counting information (NbRot) intended to represent the number of rotations counted at each moment. The counting information (NbRot) represents the number of rotations counted from a predetermined time.

A method for localizing a person in surroundings equipped with fixed electrical appliances includes measuring an electromagnetic field radiated by one or more of these fixed electrical appliances with a magnetometer carried by the person, identifying a fixed appliance operating near the magnetometer by comparing the measured field with pre-recorded magnetic signatures. Each pre-recorded magnetic signature is associated with an electrical appliance present in the surroundings. The person is then localized at least in part based on pre-recorded items of information that correspond to localization, in the surroundings, of the fixed electrical appliance as identified by its magnetic signature.

This method for localizing a person in surroundings equipped with fixed electrical appliances comprises:the measuring of an electromagnetic field radiated by one or more of these fixed electrical appliances by means of a magnetometer carried by the person to be localized,the identifying of the fixed electrical appliance operating in proximity to the magnetometer by comparing the measured magnetic field with pre-recorded magnetic signatures, each pre-recorded magnetic signature being associated with a respective electrical appliance present in the surroundings, andlocalizing the person from pre-recorded items of information on the localization in the surroundings of the fixed electrical appliance identified by its magnetic signature.
摘要:
A method of reconstructing, in two dimensions, a path of a living being or of an object moving, by a repetitive movement, in a plane or a two-dimensional surface or along a plane or a two-dimensional surface, including: measuring at least two variable components of the projection of the terrestrial magnetic field on at least two axes of a biaxial or triaxial magnetometer connected to or situated on the living being or object, measuring the period, or frequency, of a signal corresponding to the measurement of at least one of the variable components along one of the axes of the magnetometer, measuring the heading, or direction, of the movement, from at least two field measurements along at least two axes of the magnetometer, and reconstituting the path from the measurements of period or frequency and of heading or direction.

摘要:
The inventive optical device for measuring the thickness of a medium which is at least partially transparent for an incident beam and covers a second medium comprises a laser for generating the light incident beam in such a way that a beam reflected by the first medium surface and a beam scattered by the second medium surface are formed. The device comprises a photosensitive linear array for detecting the reflected beam and the scattered beam and a processing circuit which is connected to the linear array and enables to measure a space between the reflected beam and the scattered beam and to determine the thickness of the first medium according to the measured space. The processing circuit determines a distance between the linear array and the surface of the second medium from the position of at least one beam and corrects the valve of the thickness of the first medium according to the distance.
摘要:
A device for counting the number of rotations of an object in a system, in which a storage means carries counting data designed to represent the number of rotations counted. The counting data is used for conditionally resetting the storage means if and only if two separate conditions are fulfilled, where at least of one of the conditions is the reception of information from an external device, thereby insuring that the counting data represents the number of rotations counted from a predetermined time.
