20150303462 | Method For Producing An Electrode For A Lithium Accumulator And Associated Electrode - A method for producing an electrode comprising a core-shell nanocomposite material of which the core is made from silicon and the shell from carbon is provided. The method includes A) synthesising the nanocomposite material by pyrolysing a silicon core to form a core and then pyrolysing a carbon shell precursor to form a carbon shell around the core, wherein the quantities of silicon and carbon precursor are injected in a proportion such that the mass percentage of carbon in the nanocomposite material is greater than or equal to 45%; B) dispersing the nanocomposite material synthesised in step A) in a solvent to form an ink; C) applying this ink to a support intended to form an electricity collector; D) eliminating the solvent from the ink applied to the support in step C) to obtain the electrode; E) pressing or calendaring the electrode. | 10-22-2015 |
20150032408 | SYSTEM FOR CAPTURING MOVEMENTS OF AN ARTICULATED STRUCTURE - A system for capturing the movements of a body having substantially rigid segments articulated together includes attitude units fastened onto the segments of the body, the units each including at least one accelerometer and one magnetometer, and a reduced number of gyroscopes. The system also includes a pseudo-static state detection module and a module for calculating pseudo-static angles. When all segments are detected in a pseudo-static state, the state vector is provided by the module for calculating pseudo-static angles. When a segment is detected in a dynamic state, the state vector is provided at the output of a Kalman filter. | 01-29-2015 |
20140324219 | CONTROL METHOD FOR CONTROLLING A ROBOT AND CONTROL SYSTEM EMPLOYING SUCH A METHOD - A control method for the control of a robot by an operator, using control means which may be positioned at will at different locations of an item to be manipulated, comprises at least a step of determining the position and attitude of the control means on the basis of measurements of forces applied to the control means, defining a first force torsor, and on the basis of corresponding forces, at the gripping member of the robot for example, a step of determining force or force/position control setpoints for the robot on the basis of, at least, measurements of forces on the control means applied to move the item, and of the position and attitude determined during the determination step, and a control step in which the determined setpoints are sent to the robot. A control system employing such a method is also provided. | 10-30-2014 |
20140098750 | DYNAMIC MANAGEMENT OF SMALL CELLS FOR TRAFFIC-RELATED OPTIMIZATION OF THE ENERGYCONSUMPTION OF A NETWORK - The invention concerns a method for managing a network of a plurality of small cell base stations arranged in a macro-cell and linked to a base station of the macro-cell, each small cell base station being adapted to cover a small cell of the macro-cell and to be linked via radio to at least one mobile terminal present in the small cell. | 04-10-2014 |
20130057658 | Method for Detection of Targets in Stereoscopic Images - A method for detection of a target present on at least two images of the same scene captured by separate cameras comprises a prior step for learning about targets under setup conditions and further comprises, under conditions of use, a simultaneous classification step for objects present on the images, the target being said to be detected as soon as an object is classified as being one of the targets learned during the learning step. The classification step includes a step for adapting at least one of the images to the setup conditions under which the learning step took place. Application: surveillance, assistance and safety based on stereoscopic images. | 03-07-2013 |
20120329194 | METHOD FOR TREATING A SILICON SUBSTRATE FOR THE PRODUCTION OF PHOTOVOLTAIC CELLS, AND PHOTOVOLTAIC CELL PRODUCTION METHOD - The invention relates to a method for treating a silicon substrate for the production of photovoltaic cells against reduction in yield during the illumination of said photovoltaic cells.
