Abstract: A locating device equipping a mobile body, comprises an inertial platform, a 3D gyrometer and accelerometer, a calculation unit receiving measurements of the gyrometer and accelerometer a sampling frequency, and means to locate the mobile body, the calculation unit performing: a preliminary step where the mobile body travels a known trajectory, calculation of a coefficient of proportionality between distance actually traveled and raw distance obtained by integrating the time derivative of the acceleration along the trajectory; a following step of free displacement, location of the mobile body by dead-reckoning navigation procedure, being performed by using distance traveled the raw distance corrected by the proportionality coefficient.

Abstract: The invention includes a portable device and a method for the geolocation and continuous location of an object moving in a constrained environment. This device includes: means to determine the movement speed vector of this object by anemometer reading able to make measurements of relative wind caused by the movement of the object, and to deliver a corresponding signal, means for processing this signal able to calculate the speed vector of this object and its position.

Abstract: A micro-force sensor comprising a one-piece plate including a first area defining a first recess, which must be held in position relative to a mounting, a second area connected to the first area defining the first recess and a second recess, a measuring beam across the first recess having a first end embedded in the first area and a second end connected to the second area, an excitation beam across the second recess having two ends embedded in the second area and being provided with at least one excitation element, a third area connected to the first area and an effector beam having one free end for receiving the force being measured and one end-embedded in the third area, and a fourth area connecting the embedded end of the effector beam to the second end of the measuring beam, which is provided with a measuring element.

Abstract: An observation device of a non-linear system includes: at least one sensor supplying a measurement vector each component of which is a measurable output parameter of the non-linear system; and a state observer processor that, based on a predetermined state representation of the non-linear system, is configured to supply an estimation of a state vector of the non-linear system according to the measurement vector supplied and a control vector of the non-linear system. In addition, the predetermined state representation including a non-linearity model of the system in a form of a gain parameter, and one component of the state vector is this gain parameter.
