    摘要： 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.

    摘要： A method for estimating a path of a moving element or body using a sensor assembly includes: receiving acceleration values provided by an accelerometer; receiving angular velocity values provided by a gyrometer; processing the values provided for estimating at least one angular position value using the angular velocity values and at least two Cartesian position values defining a path of the moving element or body using acceleration values and the at least one previously estimated angular position value; estimating rotation parameters, by inverting a rotational realignment model of the estimated path subject to prior knowledge of the path; retroactively correcting the at least one estimated angular position value, by applying a rotation on this value using estimated rotation parameters, so as to provide at least one corrected angular position value.

    摘要： Tactile surface texture characterization method comprising at least the following steps: at least one force perceived by a force sensor during a relative displacement of said sensor with respect to a surface to be characterized is measured (211); one or more time and/or frequency parameters of an output signal delivered by said sensor, representative of the previously measured force, are calculated (213); and the value of a tactile descriptor is determined (215) from a plurality of tactile descriptors by applying a calculated transfer function, the transfer function being determined beforehand by regression from a learning database associating, for each descriptor, several values of the tactile descriptor in question with several values of one or more time and/or frequency parameters calculated from measurements carried out by the force sensor on several test surfaces representative of values of the tactile descriptor in question.
