20100061501 | CRITICALITY PREVENTION DEVICES AND METHODS IN NUCLEAR FUEL PRODUCTION - The invention concerns a vessel for processing, transfer, accumulation and/or transfer of material containing civilian or military origin plutonium, in the form of plutonium oxide, carbide and/or nitride. The plutonium is preferably present in a concentration not higher than a guaranteed maximum between 20 and 50% wt. in said material, possibly with other actinides such as americium, neptunium, or curium. Said material is preferably in form of powder, granulate and/or tablets. The vessel comprises a volume of 20 to 70 liters for containing said material, demarcated at least by two substantially parallel walls, these two walls being separated by a distance e between 8 and 15 cm. The invention concerns also an enclosure comprising analogous geometrically safe criticality-preventing means (bottom-catcher), a fuel production plant comprising a set of such vessels, preferably installed in a set of said enclosures, as well as a nuclear fuel production process carried out in a set of such vessels, preferably installed in a set of said enclosures. | 03-11-2010 |

20110267514 | Method to compensate the effect of the rolling shutter effect - A method to create a video sequence of a plurality of resultant images is disclosed. The video sequence is produced from images originating from a rolling shutter acquisition sensor. | 11-03-2011 |
20110279685 | METHOD AND SYSTEM FOR AUTOMATIC OBJECTS LOCALIZATION - A method for automatic localization of objects in a mask. The method includes building a dictionary of atoms, wherein each atom models the presence of one object at one location and iteratively determining the atom of said dictionary which is best correlated with said mask, until ending criteria are met. The invention system concerns also automatically detects objects in a mask. At least one fixed camera is provided for acquiring video frames. A computation device is used for calibrating at least one fixed camera for extracting foreground silhouettes in each acquired video frames for discretizing said ground plane into a non-regular grid of potential location points for constructing a dictionary of atoms, and, for finding objects location points with the previous method. And a for propagating device is provided to propagate the result in at least one fixed camera view. | 11-17-2011 |
20140146132 | OMNIDIRECTIONAL SENSOR ARRAY SYSTEM - An omnidirectional sensor array system, for example a panoptic camera, comprising a plurality of sensors arranged on a support of predetermined shape to acquire data, wherein said sensors are directional and wherein each sensor is attached to a processing node which comprises integrated electronics that carries out at least a portion of the signal processing algorithms locally in order to reduce the computational load of a central hardware unit. | 05-29-2014 |
20140148714 | AUTOMATIC ONLINE DELINEATION OF A MULTI-LEAD ELECTROCARDIOGRAM BIO SIGNAL - Method for automatic online delineation of an electrocardiogram (ECG) bio signal, said method comprising the detection of said bio signal through several leads followed by the combination of those multiple acquisitions into a single root-mean-squared (RMS) curve, said RMS curve being then undergoing a real-time single-lead delineation based on a mathematical processing. | 05-29-2014 |
