Description

Dispositif filtre de mise en bouche d'aliments avec un couvert  Filter device for placing food in the mouth with a cover
La présente invention concerne un dispositif de filtre de détection et d'alarme de mise en bouche de couvert.  The present invention relates to a filter device for detecting and alarming canning in the mouth.
L'invention vise à offrir une détection optimale de la mise en bouche de couvert. Cette détection permet notamment de déclencher des alarmes temps réel lorsque la prise de repas est trop rapide. Ces alarmes permettent à l'utilisateur en temps réel de prendre conscience de sa prise de repas et donc de ralentir sa prise de repas. Il est connu le brevet US 12/227,835 qui détecte la mise en bouche des aliments au moyen d'un dispositif électronique de dite détection capacitive intégrée dans la fourchette. Cette solution fonctionne parfaitement avec une fourchette seule. Un défaut de cette solution est qu'elle fonctionne mal avec l'utilisation d'un couteau. En effet, avec la technologie actuelle, si jamais l'utilisateur vient à toucher la fourchette avec son couteau l'événement est alors détecté comme une mise en bouche d'aliments. Cette détection a lieu car le contact se fait entre le couteau conducteur tenu par une main par l'utilisateur et la fourchette. La fourchette ne sait pas alors filtrer cet événement de contact avec la main et le couteau de l'utilisateur de celui du contact avec la bouche de l'utilisateur.  The invention aims to provide optimal detection of the setting in mouth of cover. This detection makes it possible to trigger real-time alarms when the meal is too fast. These alarms allow the user in real time to become aware of his meal and therefore to slow down his meal. It is known from US patent 12 / 227,835 which detects the mouthing of food by means of an electronic device of said capacitive detection integrated into the range. This solution works perfectly with a fork alone. A flaw in this solution is that it works poorly with the use of a knife. Indeed, with the current technology, if ever the user comes to touch the fork with his knife the event is then detected as a mouthing of food. This detection takes place because the contact is made between the driver's knife held by one hand by the user and the fork. The fork does not know then to filter this event of contact with the hand and the knife of the user of that of the contact with the mouth of the user.
Un objet principal de l'invention est donc de proposer un dispositif de détection d'aliments qui filtre les fausses détections parasites qui sont celles de détection par le couteau de l'utilisateur. L'invention vise à proposer une fourchette dite intelligente qui capte les événements de mise en bouche mais qui filtre les faux événements de détection par le couteau de l'utilisateur. Le couteau de l'utilisateur étant un couteau courant en métal ou en inox. A main object of the invention is therefore to propose a food detection device which filters false parasitic detections which are those of detection by the knife of the user. The invention aims to propose a so-called intelligent range which captures the events of mouthing but which filters the false detection events by the knife of the user. The knife of the user being a running knife in metal or stainless steel.
Un objet de l'invention est de proposer un dispositif qui soit économique et facilement industrialisable.  An object of the invention is to provide a device that is economical and easily industrializable.
Dans un aspect principal, l'invention propose de rajouter à la détection capacitive un filtre de fausse détection par analyse de position et de mouvement de la fourchette.  In a main aspect, the invention proposes to add to the capacitive detection a false detection filter by analysis of position and movement of the range.
Dans un aspect cette analyse de position et de mouvement est logée dans la fourchette.  In one aspect, this analysis of position and motion is in the range.
Dans un aspect cette analyse de position et de mouvement est logée dans un téléphone portable.  In one aspect this position and movement analysis is housed in a mobile phone.
L'invention propose un premier filtre par analyse d'inclinaison de fourchette.  The invention provides a first filter by tilt angle analysis.
L'invention propose un second filtre par analyse de mouvement L'invention propose un troisième fïlter par analyse mixte de mouvement et d'inclinaison  The invention proposes a second filter by motion analysis. The invention proposes a third filter by combined motion and inclination analysis.

La figure 1 représente une vue générale du dispositif de régulation de l'alimentation (1) selon l'invention. Il comprend logé dans un manche Figure 1 shows a general view of the power control device (1) according to the invention. He understands lodged in a sleeve
(10) d'un couvert, cuillère, fourchette, un dispositif de traitement de données comprenant un circuit de détection capacitive (11), un circuit de traitement électronique de traitement des données (12) et un dispositif de mesure d'inclinaison et de mouvement de fourchette (13). Lorsque l'utilisateur met les aliments (A) en bouche (B), la partie de tête de prise (30) du couvert conductrice, rentre en contact avec la bouche de l'utilisateur. Cet événement est détecté par le circuit de détection capacitive(10) a cover, spoon, fork, a data processing device comprising a capacitive sensing circuit (11), an electronic data processing circuit (12) and a tilt and turn measurement device fork movement (13). When the user puts the food (A) in the mouth (B), the grip head portion (30) of the conductive cover, comes into contact with the mouth of the user. This event is detected by the capacitive sensing circuit
(11) . L'invention vise à bien filtrer cet événement parasite comme celui du contact du couteau avec la fourchette. L'invention propose ainsi son dispositif et son procédé de filtrage de détection qui comprend un dispositif de mesure de mouvement et d'inclinaison de la fourchette (13). Le dispositif de mesure de mouvement et d'inclinaison de la fourchette (13) mesure d'abord l'angle (A) que fait le manche de la fourchette avec l'horizontal. Cet angle est indépendant de la rotation du manche autour de cet axe longitudinal. Pour être encore plus explicite, ce qui est mesuré est si le manche de la fourchette pointe vers le bas et non pas si les dents de la fourchette pointent à gauche, à droite, vers le bas ou vers le haut. Ce que cherche à mesurer l'invention est l'inclinaison du manche longitudinal de la fourchette par rapport à l'horizontal. Sous une première forme cette inclinaison est indépendante de la rotation du manche autour de son axe longitudinal. Comme représenté en figure 3, l'invention propose le filtrage suivant qui est qu'une détection avec une fourchette qui pointe vers le bas en dessous d'un certain angle (I) aura une probabilité de 1 que cet événement soit une fausse détection (N) et qu'une détection avec une fourchette qui pointe vers le haut au dessus d'un certain seuil (II) aura une probabilité de 1 que cet événement soit une vraie détection (O). Sous une autre forme, l'angle mesuré de la fourchette autour de son axe devient aussi un élément de mesure et de filtrage. Pour être plus explicite, savoir si les dents de la fourchette pointent vers le bas ou pointent vers le haut. Les événements de détection sont filtrés si et seulement si la fourchette pointe vers le bas avec les dents de la fourchette qui pointent aussi vers le bas. Cette position est notamment celle de piquage de la fourchette qui vient piquer un aliment pour le saisir. La fourchette étant alors en quelque sorte utilisée comme une fourche. Par contre selon cette seconde version de l'invention, les événements de fourchette qui pointent vers le bas avec les dents de la fourchette qui elles ne pointent pas vers le bas, c'est-à-dire une fourchette qui est utilisée comme une pelle de ramassage ne sont eux pas filtrés. Le dispositif de mesure de mouvement et d'inclinaison de la fourchette (13) mesure ensuite les accélérations verticales de la fourchette. Le dispositif de mesure des accélérations est préférentiellement logé au centre de gravité de la fourchette, et particulièrement à une distance comprise entre 40% et 65 % de la longueur de la fourchette. Cette localisation permet de lire les accélérations verticales qui sont masquées par des effets de rotation du poignet de l'utilisateur lorsque la lecture est trop basse sur le manche, et qui sont corrompues par trop de bruit parasite lorsqu'elles sont trop hautes sur le manche. Elle s'effectue par des moyens ou des combinaisons de moyens du type accéléromètre, gyroscope et / ou magnétomètre. Ce qui est ici mesuré est le fait de savoir si l'utilisateur monte, descend sa fourchette ou la laisse dans son plan horizontal. Pour être de nouveau explicite, il s'agit ici de filtrer si l'utilisateur monte la fourchette ou s'il la laisse dans son assiette pour opérer sur les aliments dans l'assiette. Le procédé de filtrage de détection selon l'invention fonctionne comme expliqué en figure 3, avec un second filtre qui opère pour des inclinaisons de fourchette dont l'angle d'inclinaison est compris entre le seuil bas (I) et le seuil haut (II). Dans cette frange d'angle d'inclinaison, le filtre opéré est de mesurer l'accélération verticale de la fourchette. Si, avant la détection, la fourchette n'a pas enregistré comme dernière accélération une accélération verticale positive, alors l'événement est filtré comme une fausse détection (N). Si par contre, avant la détection, la fourchette a enregistré comme dernière accélération une accélération verticale positive, alors l'événement est filtré comme une vraie détection (O). Il est bien compris que le second filtre de détection par analyse du mouvement vertical peut fonctionner en solo sans le premier filtre de détection par mesure d'angularité du manche de fourchette. (11). The invention aims to filter well this parasitic event as that of the contact of the knife with the fork. The invention thus proposes its device and detection filtering method which comprises a device for measuring the movement and inclination of the fork (13). The fork movement and tilt measuring device (13) first measures the angle (A) of the fork handle with the horizontal. This angle is independent of the rotation of the handle about this longitudinal axis. To be even more explicit, what is measured is if the handle of the fork is pointing downwards and not if the teeth of the fork are pointing to the left, right, down or up. What seeks to measure the invention is the inclination of the longitudinal handle of the fork relative to the horizontal. In a first form this inclination is independent of the rotation of the handle about its longitudinal axis. As shown in FIG. 3, the invention proposes the following filtering which is that a detection with a fork pointing downwards below a certain angle (I) will have a probability of 1 that this event is a false detection ( N) and that a detection with a range pointing upwards above a certain threshold (II) will have a probability of 1 that this event is a true detection (O). In another form, the measured angle of the fork around its axis also becomes a measuring and filtering element. To be more explicit, find out if the fork teeth are pointing down or pointing up. The detection events are filtered if and only if the fork is pointing down with the fork teeth pointing downwards as well. This position is particularly that of pricking the fork that comes prick a food to grab it. The fork is then somehow used as a fork. On the other hand, according to this second version of the invention, fork events that point downwards with the fork teeth that do not point downward, that is to say a fork that is used as a shovel pickup are not filtered. The device for measuring movement and inclination of the fork (13) then measures the vertical accelerations of the fork. The device for measuring acceleration is preferably housed at the center of gravity of the range, and particularly at a distance of between 40% and 65% of the length of the range. This location makes it possible to read the vertical accelerations which are masked by effects of rotation of the wrist of the user when the reading is too low on the handle, and which are corrupted by too much parasitic noise when they are too high on the handle . It is carried out by means or combinations of means of the accelerometer, gyroscope and / or magnetometer type. What is measured here is whether the user goes up, lowers his fork or leaves it in his horizontal plane. To be explicit again, it is a matter of filtering if the user raises the fork or if he leaves it on his plate to operate on the food on the plate. The detection filtering method according to the invention operates as explained in FIG. 3, with a second filter which operates for fork inclinations whose inclination angle is between the low threshold (I) and the high threshold (II). In this tilt angle fringe, the filter operated is to measure the vertical acceleration of the range. If, before detection, the range has not recorded as a final acceleration a positive vertical acceleration, then the event is filtered as a false detection (N). If, on the other hand, before the detection, the range has recorded a positive vertical acceleration as the last acceleration, then the event is filtered as a true detection (O). It is well understood that the second detection filter by vertical motion analysis can operate solo without the first detection filter by measuring the angularity of the fork handle.
Une autre façon de filtrer les événements est la suivante, voir figure 4 : Une détection (D) est détectée par la fourchette, puis un mécanisme de deux filtrage successifs détermine  Another way of filtering events is as follows, see Figure 4: A detection (D) is detected by the range, then a two successive filtering mechanism determines

• Critère 4 : Durée depuis la dernière détection  • Criterion 4: Duration since last detection
Chaque critère 1 à 4 est affecté d'un coefficient qui donne un poids particulier à chaque indicateur et qui donne une proposition d'analyse sur le fait que la détection soit Vraie ou Fausse.  Each criterion 1 to 4 is assigned a coefficient which gives a particular weight to each indicator and which gives a proposition of analysis on the fact that the detection is True or False.
La présente invention concerne donc un dispositif de détection de mise en bouche (B) d'aliments (A) par une fourchette à détection capacitive dont les dents (30) sont en contact avec un circuit de détection capacitive (11), en liaison avec un circuit de traitement électronique de traitement des données (12) caractérisé en ce que un dispositif de mesure (13) analyse à chaque détection capacitive de la fourchette, l'inclinaison et le mouvement de la fourchette, un dispositif de filtrage (12, 13) filtre chaque détection capacitive sur les dents de la fourchette en qualifiant les détections capacitives soit comme des mises en bouche d'aliments par la fourchette (V) soit comme de fausses détections (F) de contact de la fourchette avec le couteau.

The present invention therefore relates to a device for detecting and filtering real (V) detection and false detections (F) of placing food in the mouth by a capacitive fork characterized in that a mechanism of two successive filtering, Filter 1 (Fl) according to mixed criteria of analysis of teeth up, tooth down, upper sleeve, bottom sleeve and Filter 2 (F2) by a weighting of different criteria of captures of movements including that of analysis of position time, acceleration and deceleration, path evaluation and time interval measurement between events, each is assigned a coefficient that gives a particular weight to each indicator and that gives a proposition of analysis on the fact that the detection is True (V) or False (F).
Dans une variante de l'invention, la fourchette est équipée d'un capteur de poids qui mesure le poids d'aliments porté par les dents de la fourchette. La gestion de l'évolution du poids en bout de fourchette contribue au filtrage de fausses détections de mise en bouche de fourchette.  In a variant of the invention, the fork is equipped with a weight sensor which measures the weight of food carried by the teeth of the fork. The management of the evolution of the weight at the end of the range contributes to the filtering of false detections of setting in mouth of fork.
Il est donc bien compris que de nombreuses variantes à l'invention peuvent s'inscrire dans le cadre de la présente invention.  It is thus well understood that many variants of the invention may fall within the scope of the present invention.
