  • Patent number: 9701013
    Abstract: The invention relates to a method for controlling a robot (1) defined by a node model and deformable by means of actuators (2). Effector points of the robot must follow a predetermined path. A matrix K defines a change in the inner forces of the robot in each node, on the basis of the change in position of the nodes. Said method includes: updating the K values on the basis of the current position of the nodes of the robot; determining the Jacobian matrix J of the vector ?(x), x being a vector of the position of the nodes and the vector ?(x) comprising respective lines which indicate the coordinates of the gaps between the position of each effector point and the predetermined path thereof, and the movement of each actuator; calculating the values of the matrix W=J·K?1·JT; and solving the equation ?=W·?+?0 and controlling the robot on the basis of said resolution.

  • Publication number: 20170154112
    Abstract: The invention relates to a method of masking data making up a user profile associated with a node of the network, a user profile consisting of a sub-set of elements present from among a set of possible elements. The masking method includes a step for obtaining an initial data structure including a pre-determined number of binary elements, a so-called binary element being able to have a value from two possible values, the initial data structure being representative of the elements present in the user profile, and, for at least one portion of said binary elements, a step for applying a probabilistic inversion operation of the value of said binary element, depending on a probability value calculated from a pre-determined confidentiality parameter, giving the possibility of obtaining a masked data structure representative of the elements present in the user profile.

  • Publication number: 20140336993
    Abstract: A multipurpose computing device includes a solver receiving a working matrix and an initial matrix corresponding to a system of equations and residual data; and an adapter receiving the initial matrix as well as a filtering matrix and calculates a working matrix corresponding to an equation system solved by the solver. The working matrix checks a stability condition with the initial matrix, comprising a comparison of two matrix products including the filtering matrix or the transpose thereof, and the initial matrix and the working matrix, respectively. The adapter renumbers the initial matrix and the filtering matrix in order to produce a modified matrix and a modified filtering matrix using an ordering rule that is a function of a dependency condition, and recursively calculates the working matrix representation with these matrices. The solver works recursively on the working matrix to provide a solution without inverting the initial matrix.
