20130330557 | METHOD FOR THE DRY GRANULATION OF NANOMETRIC PARTICLES - A method of forming micrometric or millimetric sized granules by the agglomeration of nanometric sized particles, comprising the addition of a set of nanometric sized particles into a container having an inside wall surface with a circular or approximately circular section and setting the set of particles in motion along said inside wall surface by rotating the container about a rotation axis passing through said container. The setting in motion of the particles is done in a dry state and the container is rotated continuously at constant speed for several consecutive hours. | 12-12-2013 |
20130247058 | SYSTEM FOR SCHEDULING THE EXECUTION OF TASKS BASED ON LOGICAL TIME VECTORS - A method for scheduling interdependent tasks on a multi-task system includes: associating to each task a logical time vector indicative of the current occurrence of the task and the occurrences of other tasks on which the current occurrence depends; defining a partial order on the set of logical time vectors, such that a first vector is greater than a second vector if all first vector components are greater or equal to the respective second vector components, and at least one component of the first vector is strictly greater than the respective component of the second vector; after an execution of a task, updating its logical time vector for a new occurrence by incrementing at least one component of the vector; comparing the logical time vectors according to the partial order relation; and executing each task having a logical time vector smaller than all other logical time vectors. | 09-19-2013 |
20120134586 | DEVICE WITH DATASTREAM PIPELINE ARCHITECTURE FOR RECOGNIZING AND LOCATING OBJECTS IN AN IMAGE BY DETECTION WINDOW SCANNING - A device for recognizing and locating objects in an image by scanning detection windows comprises a data stream architecture designed in pipeline form for concurrent hardware tasks and includes means for generating a descriptor for each detection window, a histogram determination unit determining a histogram of orientation gradients for each descriptor, and N processing units in parallel, capable of analyzing the histograms as a function of parameters associated with the descriptors to provide a partial score representing the probability that the descriptor concerned contains at least part of the object to be recognized, the sum of the partial scores of each detection window providing a global score representing the probability that the detection window contains the object to be recognized. | 05-31-2012 |
20100272214 | RADIOFREQUENCY TRANSMISSION SYSTEM - The invention relates to a radiofrequency transmission system comprising: means of producing a complex digital signal quantised on N bits; means of transforming the complex digital signal into two complex digital signals with an identical and constant envelope that are phase-shifted with respect to one another; a digital processing pathway associated with each of the two complex digital signals with a constant envelope and comprising at least some filtering means of the sigma-delta type for quantising on M bits signals travelling in the processing pathway, M being less than N; digital-to-analogue conversion means for converting the outputs of the digital processing pathways into analogue signals; means of selectively filtering (of the bandpass type) the analogue signals in a predetermined transmission frequency band; means of amplifying the filtered analogue signals; and means of recombining the amplified analogue signals. | 10-28-2010 |
