Abstract: C`est un nouveau mécanisme de télécourrier qui remplace la poste. Ce mécanisme permettra à chacun de gérer son courrier personnel et de l`expedier de chez lui ou d`ailleurs, tant qu`il ya un téléphone à sa portée. Avec ce mécanisme on expédie notre courrier urgent par téléphone et au lieu d`aller à la poste on va simplement faire un appel téléphonique. En d`autres termes la technique que je presente consiste dans le fait qu`à partir d`un appel de téléphone on peut expédier une lettre enregistrée, express (télécopie) et accusée de réception sauf que dans la présente invention on n`a pas à avoir recours à un ordinateur ni à une télécopieuse. Tout le mécanisme consiste dans le changement de la technique actuelle tout en élaborant la succession des etapes commencant par la transmission de l`appel en tant que message jusqu`à sa phase de réception en tant que document imprimé et enregistré.

Filed: 1996-02-29
Abstract: Système porteur permettant de soutenir au moins un panneau pare-balles souple sensiblement imperméable à l'humidité au niveau du torse de celui qui en est revêtu. Ce système est constitué de sections ventrale et dorsale de gilet, qui, pour chacune d'entre elle, sont constituées d'un seul pan de tissu qui absorbe l'humidité. Ce morceau de tissu est plié par rapport à sa ligne médiane transversale et lié solidement autour de ses bords respectifs non repliés pour former une poche dans laquelle un ou plusieurs des panneaux pare-balles souples en question peuvent être insérés. La section ventrale du gilet peut être attachée de manière ajustable et desserable à la section dorsale du gilet grâce à un moyen de fixation desserable qui fait coopérer les deux sections, ce système étant installé sur chacune des deux sections ventrale et dorsale pour constituer un système porteur. En pratique, ce système porteur permet d'obtenir un vêtement plus confortable que les systèmes connus, car chaque section du gilet permet à la transpiration de celui qui porte ce gilet de se dégager autour du panneau pare-balles souple en s'absorbant autour de la ligne médiane transversale et de gagner la surface externe du système porteur où l'évaporation est efficace.

Abstract: Une commande d'un générateur électrochirurgical (11) répond à l'impédance des tissus entre des électrodes actives et des électrodes de retour (12 et 13) lors de la dessiccation. Les conducteurs actifs et les conducteurs de retour du générateur fournissent l'énergie (25) et un dispositif de commande d'utilisateur (16) règle le niveau d'énergie (25) désiré pour l'électrochirurgie. Des circuits de détection de tension et de courant (19) répondent à l'énergie haute fréquence (25) dans les conducteurs afin d'émettre un signal de tension et de courant dans ces derniers. Un multiplicateur (21) reçoit les signaux pour calculer la puissance. Une horloge (23) établit des unités de temps au cours desquelles s'effectue le calcul de puissance. Un intégrateur (24) calcule l'énergie (25) fournie par les conducteurs par unité de temps. Le dispositif de commande d'utilisateur (16) établit un signal de référence (26) pour le niveau d'énergie (25) désiré. Un circuit de corrélation (27) reçoit les calculs d'énergie (30) provenant de l'intégrateur (24) ainsi que le signal de référence (26), et émet un signal de réaction (28) afin d'indiquer si la valeur calculée de l'énergie (25) est égale au réglage de la commande d'utilisateur (16), ce qui sert à modifier l'alimentation en énergie (25) des conducteurs. Un compteur (38) évalue le nombre de paquets d'énergie (40) fournis par rapport à un réglage de la commande d'utilisateur (16) et l'énergie totale (25) fournie est fonction des séquences de paquets multiples contenant des impulsions, l'intervalle entre les impulsions étant commandé par la commande d'utilisateur (16). Le procédé fait appel à la commande automatique (10) afin de mesurer l'impédance lors de la dessiccation des tissus et de modifier la sortie d'un générateur électrochirurgical (11).
