Title: Procede et dispositif d'extraction d'estimateurs des caracteres d'un ecoulement instationnaire a partir d'un signal doppler a valeurs complexes
Inventor: HERMENT ALAIN
IPC: G01P5/24
Filed: 1990-03-22
Abstract: Le procédé et le dispositif sont notamment utilisables pour extraire les estimateurs du signal Doppler en imagerie médicale ultrasonore. Le dispositif utilise comme paramètre d'entrée, pour calculer la fréquence moyenne, les coefficients de corrélation Im(Cxx) correspondant à la partie imaginaire du signal. Ces coefficients sont appliqués en séquence à une entrée d'un multiplieur (10). L'autre entrée reçoit des coefficients de pondération de la forme 0, 1/0, 1/pi,...,(-1)p+1/pip, où p est le nombre de coefficients de pondération, stockés dans un registre (11). Les produits partiels sont accumulés et fournissent une somme représentative de la fréquence moyenne.

Abstract: PCT No. PCT/CH90/00228 Sec. 371 Date May 24, 1991 Sec. 102(e) Date May 24, 1991 PCT Filed Sep. 26, 1990 PCT Pub. No. WO91/04709 PCT Pub. Date Apr. 18, 1991.The instrument for handling biopsies and specimens comprises a main body (3) the shape of which is similar to that of a syringe, a piston (4), a recoil means (7) and a portion (5) for contact with the specimen (2). In order that the degree of accomplishment of the suction effect caused by the action of the recoil means (7) shall not prejudice the ejection effect, a microchannel (8) as a calibrated air inlet enables the compensation of the deficit in volume when the specimen is obstructing the orifice (6) of the suction-ejection channel (10). Ejection of the specimen by airjet may thus take place in every case from a position of the piston corresponding with maximum volume.

Abstract: On décrit une analyse rapide, sensible et spécifique permettant de détecter des anticorps aux maladies infectieuses. La méthode fait appel à un élément poreux sur lequel est immobilisé une matière de liaison pouvant se lier aux anticorps d'une sous-classe ou des sous-classes données, présentes dans l'échantillon d'essai. Selon la méthode décrite, lorsque l'échantillon renferme des anticorps à la maladie infectieuse d'intérêt il se forme un complexe ternaire de la matière de liaison, de l'anticorps d'intérêt et d'une matière de détection étiquetée, par exemple un antigène étiqueté, qui est spécifique à l'anticorps d'intérêt. Après enlèvement de la matière de détection étiquetée de la zone de réaction, on détecte toute matière de détection étiquetée afin d'obtenir une indication de la présence des anticorps d'intérêt.
