Abstract: Un système de sécurité électronique comprend un mécanisme de verrouillage électronique et une clé électronique (101), pourvus chacun d'une unité de contrôle à microprocesseur et d'une mémoire mémorisant des données comprenant un code d'identification et des codes de clé de chiffrement. Le microprocesseur de verrouillage peut soit modifier les codes d'identification mémorisés dans sa mémoire, soit chiffrer un nombre de départ s'utilisant pour déterminer l'accès au verrou. La clé ne peut s'utiliser pour accéder au verrou qu'une fois ou qu'un nombre limité de fois successives et doit ensuite être reprogrammée par un ordinateur central (301), de façon à la charger soit avec le code d'identification correct, soit avec le code de clé de chiffrement approprié pour ledit verrou. Le verrou électrique actionne un solénoïde (1624) qui rétracte un mécanisme de blocage de verrou empêchant le déverrouillage dudit verrou même quand on y introduit une clé possédant la configuration mécanique appropriée. Le courant servant à actionner le verrou électronique ainsi que le solénoïde provient d'une unité d'alimentation située à l'intérieur de la clé. Dans un mode de réalisation préféré, l'ensemble clé est composé d'un ordinateur portatif comportant une plaquette séparée intérieure mémorisant l'information de codes de clé et remplissant les fonctions de chiffrement/déchiffrement. L'invention décrit également un nouvel ensemble électronique à verrou en T (1340) conçu pour une utilisation sur des machines telles que des distributeurs automatiques.

Abstract: L'invention concerne le procédé permettant de détecter et de quantifier des toxines diarrhéiques des dinoflagellés en ayant recours à l'inhibition de phosphates. La présence de marées rouges productrices desdites toxines contamine les mollusques qui doivent être contrôlés en permanence avant d'être commercialisés. La technique actuelle est le bioessai qui consiste à administrer un extrait de mollusque à des rats; le résultat est positif si le rat meurt avant qu'un laps de temps de douze heures se soit écoulé. Ce procédé est lent, coûteux, erratique et peu spécifique. Le procédé de l'invention permet de détecter et de quantifier les toxines en mesurant l'inhibition des phosphatases partiellement purifiées. L'inhibition de phosphatases est quantifiée en utilisant comme support une plaque de microtitrage et en revelant l'activité enzymatique à l'aide d'un substrat de phosphatase qui, selon ses caractéristiques chimiques, se convertit en un produit fluorescent, luminescent ou coloré. Cette technique est rapide, économique et fiable. Le secteur pouvant bénéficier de ce procédé est l'industrie de production et de mise en conserve de mollusques.
