Title: Procede et dispositif de localisation d'entites par dielectrokinese
Inventor: AFILANI THOMAS L
IPC: G01N27/60
Filed: 1997-11-18
Abstract: La présente invention concerne un appareil de localisation permettant de détecter une force diélectrophorétique engendrée par un modèle tridimensionnel dont le carré des champs électriques est caractérisé par un gradient spatial non uniforme, ce modèle étant caractéristique de façon univoque d'un type déterminé d'entité. En l'occurrence, un opérateur humain tient à la main l'appareil de façon qu'il soit électriquement connecté à l'opérateur humain. Les circuits électroniques extérieurs connectés à l'appareil augmentent le temps de décroissance d'une très faible constante électrique naturelle de l'opérateur humain. Le procédé consiste, pour l'opérateur, à tenir l'appareil en équilibre à l'horizontale et à promener l'appareil selon un mouvement uniforme d'aller-retour avant-arrière de façon à balayer avec le champ à explorer. Une antenne, qui sort sur l'avant de l'appareil, et l'appareil lui-même, sont soumis aux influences de la force diélectrophorétique. Cette force se manifeste par des couples, des accélérations, des vibrations, et autres phénomènes induits, qui sont tous quantifiables, et qui correspondent aux effets de la force se manifestant au niveau de la ligne de pivot de la poignée, ce qui fait que ces effets entraînent l'appareil et son antenne dans la direction, et vers la position, de n'importe quelle entité du type défini se trouvant à portée de détection.

Abstract: A moving vector between frame is detected by a moving vector detecting unit and the display positions of the subfields of pixels in a block are corrected using a moving picture correcting unit in accordance with the detection values of the moving vector. The picture quality is not deteriorated when corrected. In order not to output an erroneous moving vector, a lowest correlation factor S1 detected by a lowest correlation factor detecting unit (20) is multiplied by 1.5, the correlation factors not larger than S1 are substituted by S2 (S2<=S1), and, among a plurality of blocks with the correlation factors S2, the block closest to the origin is used as the starting point of the moving vector.     In order not to input an erroneous moving vector to the moving picture correcting unit, a moving vector is determined by the majority decision of the moving vectors of surrounding blocks. The movement of a line has first priority (Fig. 13).
