A force sensor includes at least one cavity defining at least two surfaces having different orientations. On each of said surfaces is disposed at least one respective detection structure sensitive to a pressure exerted on the corresponding surface. A resiliently deformable medium at least partially fills the cavity by coming into contact with the surfaces and defines a detection surface, on which a force to be detected is likely to be exerted. The application of this force is likely to generate stresses on each detection structure due to the transmission of forces by the medium.

The invention relates to a system for recording a track comprising: a utensil comprising a tip and equipped with a magnetic object; a device for locating the magnetic object configured to determine an estimated reference position on a writing surface; and a matrix-array touch sensor configured to define a set of M pixels, among N pixels, at least partially encircling the estimated reference position, and to detect the contact of the tip on the writing surface on the basis of the electrical signals generated by said set of M pixels.

A method for estimating an angular deviation between a reference axis of a magnetic object and a magnetic axis co-linear to a magnetic moment of the magnetic object, including: a) positioning the magnetic object facing at least one magnetometer; b) rotating the magnetic object about the reference axis; c) measuring, during the rotating, the magnetic field, using the magnetomenter; and d) estimating the angular deviation from the magnetic field measurements.

A method of charging a battery of electric accumulators from the electric power supplied by an electric generator, wherein the battery is charged to a first maximum state of charge in a first operating mode and to a second maximum state of charge, lower than the first maximum state of charge, in a second operating mode, the method including switching from the second operating mode to the first operating mode when a criterion using the battery temperature or the ratio of a first quantity representative of the available power which may be supplied by the electric generator to a second quantity representative of the power consumed from the battery is fulfilled.

A method of calibrating a network of magnetometers (C, Ci) including the displacement of a magnet holder tool () above the network, and solving an optimisation problem to determine a localisation of the magnetometers in the network. This localisation minimises based on an optimisation criterion, the difference between a real attribute (D, m1, m2) of the magnet holder tool and an estimate of the attribute determined without knowledge of the displacement, starting from the localisation and measurements made by the magnetometers in the network during the displacement.

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.

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.

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.

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.
