Title
(EN) APPARATUS FOR ASSISTING THE VISUAL ASSESSMENT OF TEST OBJECTS HAVING MULTIVARIATE VISIBLE CHARACTERISTICS,AND ITS USE
(FR) APPAREIL FACILITANT LA DEFINITION VISUELLE D'OBJETS-TESTS, AYANT DES CARACTERISTIQUES VISIBLES A VARIATIONS MULTIPLES, ET SON UTILISATION
Abstract
(EN)
Apparatus for use in and for assisting the visual assessment by a human operator of test objects, in each of which test objects a multiplicity of test locations each has one or more visible characteristics capable of exhibiting any one of a number of conditions to be assessed (e.g. a prepared microtiter plate or tray having an array of test locations or wells in which a series of microbial cultures or biological or chemical tests has been carried out leading to results to be optically or visually assessed, e.g. in terms of turbidity and/or colour), the apparatus comprising: (a) means for illuminating each of the test locations of the test object (either with sufficient light to enable the operator to see and assess the test location against a background of darkness, or with an indicator light sufficient to draw the operator's attention to the test location against a general background light); (b) means for positively locating the test object in registration with the illuminating means; (c) means for controlling the illuminating means so that all of the test locations can be selectively illuminated, either singly or in groups, according to a program-determined sequence; and (d) means to enable the operator manually to actuate and control stepping along the sequence.
(FR)
Appareil utilise par un operateur contribuant a definir visuellement des objets-tests dont chacun presente une multitude de positions-tests ayant chacune une ou plusieurs caracteristiques visibles pouvant presenter une condition quelconque parmi une pluralite de conditions a determiner (p. ex. une plaque ou plaquette de microtitrage preparee ayant une rangee de positions ou puits de tests dans lesquels une serie de cultures microbiennes ou essais biologiques ou chimiques ont ete effectues se traduisant par des resultats devant etre estimes optiquement ou visuellement, p. ex. en termes de turbidite et/ou couleur), l'appareil comprenant: (a) des moyens d'eclairage de chacune des positions-tests de l'objet-test (soit avec une lumiere suffisante pour permettre a l'operateur de voir et d'estimer la position-test contre un fond sombre, soit avec une lumiere d'indication suffisante pour attirer l'attention de l'operateur sur la position-test contre un fond d'ensemble lumineux); (b) des moyens pour positionner positivement l'objet-test pour qu'il coincide avec les moyens d'eclairage; (c) des moyens de commande des moyens d'eclairage pour que toutes les positions-tests puissent etre illuminees selectivement, soit individuellement soit en groupe, en fonction d'une sequence determinee par un programme; et (d) des moyens pour permettre a l'operateur d'actionner manuellement et de commander les etapes de la sequence.
