20090197061 | PRODUCTION OF A MATERIAL MULTILAYER MICROCOMPONENTS BY THE SACRIFICIAL THICK LAYER METHOD SACRIFICIELLE - The invention relates to the preparation of multilayer microcomponents which comprise one or more films, each consisting of a material M selected from metals, metal alloys, glasses, ceramics and glass-ceramics. | 08-06-2009 |
20100201385 | METHOD FOR MEASURING THE THRESHOLD THICKNESS OF A LAYER OF A PURELY RESISTIVE MATERIAL, DEVICE FOR IMPLEMENTING SAME AND USE OF SAID DEVICE IN AN EXHAUST PIPE - The invention provides a reliable, simple, and accurate method for detecting a threshold thickness of a purely-resistive material deposited on a sensor, and providing a response that is independent of the resistivity of the material. The invention provides a measurement method using a sensor comprising at least two electrode pairs having a defined voltage applied thereto generating current between the electrodes, the electrode pairs differing by at least one first parameter selected from the width, the spacing, and the length of the electrodes, and the voltage applied to each pair, and at least one second one of said parameters being adjusted so that a first resistance or a first current between the electrodes of the first pair, and a second resistance or a second current between the electrodes of the second pair are equal when the threshold thickness is reached. | 08-12-2010 |

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 |

20150036887 | METHOD OF DETERMINING A GROUND PLANE ON THE BASIS OF A DEPTH IMAGE - A method of determining a triplet of parameters defining a ground plane based on a depth image includes determining a plurality of triplets of parameters, each defining a ground plane, spatial filtering of the parameters, and temporal filtering of the parameters. The temporal filtering is dependent on an indicator of quality of depth image data available for determination of the ground plane. The temporal filtering is dependent on an indicator of quality of the ground plane determined after spatial filtering. Similarly, the spatial filtering can be parameterized as a function of the two indicators. Globally, the more the estimated plane for a depth image can “explain” the points in this image, the more accurately planes of the subsequent images are determined. For the spatial filtering, the ground plane is searched in a more limited space, and, for the temporal filtering, the previously estimated ground planes considered to a lesser degree. | 02-05-2015 |
