Abstract:
PROBLEM TO BE SOLVED: To provide a decoder suitable for a chip having a small number of small-size contacts with sufficient intervals between the contact by determining the quantity of fluorescence of a contact to decide a density of substance mixed with the fluorescent material. SOLUTION: An image acquisition means 4 is focused on a matrix disposed and fixed below an optical axis of a microscope 1, and a reference contact aligned to the optical center of this system is automatically retrieved, while an image of one contact of the matrix is acquired. The system has a calculation part for calculating fluorescence of the contact and deducing the density of substance. An illuminating means has a ring-shaped light source 11 and a laser light source 13 for exciting a fluorescent material contained in a mixture constituting the substance. The system also has a means for recording the image of the contact and a processing means 7 for analyzing the image. Thereby, the system can determine a quantity of the fluorescence of the contact to decide the density of the substance mixed with the fluorescent material.

Abstract:
This method for locating a mobile magnetic object comprises: a) estimating (52) the position of the magnetic object relative to the network of magnetometers without making a new measurement using the magnetometers of the network, b) calculating (56) the distance between each magnetometer and the estimated position of the magnetic object, c) eliminating (60, 72, 82) the N magnetometers closest to said estimated position, then d) making a new measurement (84), by each non-eliminated magnetometer, of the magnetic field generated or modified by the magnetic object, and e) determining (86) a new position or a new orientation of the magnetic object from the new measurements of the magnetometers which have not been eliminated and without taking into account new measurements made by the eliminated magnetometers, so as to obtain a new location of the magnetic object.
Abstract:
The invention relates to a device and to a method for controlling the playback of a file of signals to be reproduced. The devices and methods of the prior art do not make it possible to control the playback of an audio file by means of the strokes of a user while guaranteeing high-quality musical rendition. The invention resolves said problem by providing a means for controlling said playback by means of strokes entered via a MIDI interface or measured by one or more motion sensors. Variations in playback speed can also be smoothed out in order to guarantee better musical rendition. The speed of the strokes can also be taken into account for controlling the volume of the audio output and other gestures or strokes can also control the tremolo or vibrato.
Abstract:
The invention relates to a device for interpreting musical gestures or gestures played on or simulating musical instruments. Prior art devices enable a user to produce music by performing gestures on a suitable instrument or accompanied by pre-recorded musical content. However, none of the prior art devices are reliable and robust enough to guarantee satisfactory musical rendition. The invention enables remarkable musical rendition due to the use of microsensors, in particular accelerometers and magnetometers or rate gyros, and due to adequate processing of the signals from the microsensors. In particular, processing includes merging of output data from the microsensors to eliminate false alarms consisting of the movements of the user that are not related to the music. The device of the invention also measures the speed of the musical strokes. The invention further enables the user to control scrolling of MP3 or WAV music files to be played.
Abstract:
The invention concerns a method and a device for capturing the movement of a solid using at least one camera and one angular sensor. The invention, which is applicable in particular to video games, is characterized in that it consists in: equipping the solid (2) with at least one first sensor (4) for observing a scene and providing an image thereof and at least a second sensor (6) for measuring a rotation; acquiring, by means of the first sensor, images at successive times, which delimit time intervals for each of which the rotation of the first sensor is determined by means of the second sensor and the translation of said solid from said images.

Procédé de détection d'un point de contact entre une pointe d'un ustensile et un support d'écriture, l'ustensile étant choisi dans le groupe composé d'un crayon et d'un effaceur, ce procédé comportant la détermination (92), à l'aide d'un objet magnétique fixé sans aucun degré de liberté sur l'ustensile, de la hauteur d'un point de l'ustensile par rapport à une face d'appui d'une tablette, cette face d'appui constituant le support d'écriture ou supportant le support d'écriture, caractérisé en ce que le procédé comporte : - la comparaison (94) de la hauteur déterminée à un seuil de contact pré-configuré, et - la détection (94) d'un point de contact entre la pointe de l'ustensile et le support d'écriture si la hauteur déterminée est inférieure au seuil de contact et, dans le cas contraire, l'absence de détection d'un point de contact entre la pointe de l'ustensile et le support d'écriture.
Abstract:
The method involves estimating a range of values using a qualitative analysis method, and additionally estimating additional ranges of values with a different method. The ranges of values are observed successively by a decreasing reliability order of the corresponding methods, and each additional range of value is compared with the former range value according to the order. The additional ranges of values are selected as a result when the additional ranges of values are included in the range corresponding to the former method.
