Title: Cryptographic device
Inventor: TAKASHIMA YOUICHI
IPC: H04L9/06
Filed: 1998-06-30
Granted: 2003-02-04
Abstract: In a secret-key cryptographic device, there are cascade-connected a plurality of round processing parts and the round processing part of each i-th round is supplied with input data L i and R i, nonlinearly transforms the input data R i in a nonlinear function part on the basis of extended key, then provides the exclusive OR between the nonlinearly transformed output and the input data L i as data R i+1 for input into the next round and outputs the input data R i as data L i+1 for input into the next round. The nonlinear function part of each round comprises: a key-dependent linear transformation part which performs a key-dependent linear transformation of the input R i; a splitting part which splits the linearly transformed output to four pieces of data in0, in1, in2 and in3; first nonlinear transformation parts which nonlinearly transform the four split pieces of data and output nonlinearly transformed data mid00, mid01, mid02 and mid03 respectively; a key-dependent linear transformation part which associates these transformed outputs with each other and, at the same time, linearly transforms them based on extended key to output data mid10, mid11, mid12 and mid13; second nonlinear transformation parts which nonlinearly transform these transformed outputs, respectively, and output data out0, out1, out2 and out3; and a combining part which combines these transformed outputs into output data Y.

Abstract: An improved membrane electrode assembly ("MEA") for an electrochemical fuel cell comprises coextensive ion exchange membrane and electrode layers and a resilient fluid impermeable integral seal comprising a sealant material impregnated into the porous electrode layers in sealing regions of the MEA. In preferred embodiments, the integral seal circumscribes the electrochemically active area of the MEA. The integral seal preferably also extends laterally beyond the edge of the MEA, thereby envelopping the peripheral region including the side edge of the MEA. An integral seal may also be provided around any openings, such as manifold openings, that are formed in the MEA. Preferably the sealant material is a flow processable elastomer applied to the MEA using an injection molding process prior to being cured. In preferred embodiments the seal has a plurality of spaced parallel raised ribs with cross ribs extending therebetween at spaced intervals. The raised ribs and cross ribs provide compartmentalized seals that provide improved protection against fluid leaks in a fuel cell assembly.

Title: Convertisseur continu-alternatif triphase et tripolaire
Inventor: WILLIAMS SCOTT LAWRENCE
IPC: H02M1/12
Filed: 1998-08-26
Granted: 2006-05-02
Abstract: Ce convertisseur triphasé continu-alternatif comprend une source de courant continu comportant un premier noeud en courant continu destiné à une tension positive, un second noeud en courant continu destiné à une tension négative, ainsi qu'un troisième noeud en courant continu destiné à une tension zéro. Un circuit de commande, sensible à un signal de demande de référence de vecteur de tension de convertisseur, ce signal présentant une composante de demande de référence d'amplitude de tension et une composante de référence de phase de tension, produit des signaux de commande de pôle destinés aux circuits tripolaires, au moyen de circuits logiques combinant des valeurs de forme d'onde numérique indexées en phase et conservées dans une paire de tables de consultation (114, 116). Les signaux de commande de pôle (118, 120) forcent les circuits tripolaires à produire un ensemble formes d'ondes décalées en phase et présentant des composantes de tension zéro. Ces formes d'onde décalées en phase sont combinées par un ensemble transformateur, afin de produire une tension de sortie triphasée présentant un pourcentage de distorsion inférieur à celui des formes d'onde décalées en phase.

Abstract: On décrit un procédé et un système de pompage extracardiaque (10) pouvant suppléer la circulation sanguine chez un patient sans qu'aucun élément dudit système ne soit raccordé au coeur du patient. Ce système de pompage extracardiaque comprend une pompe (32) implantée sous la peau du patient ou autour de son aine par intervention chirurgicale avec effraction minimale. La pompe est alimentée par une pile (44) et par un moyen extracorpel de chargement de la pile. La pompe aspire le sang à travers une conduite d'amenée (50) communiquant librement avec l'artère fémorale (26) du patient via un raccordement anastomotique sous-cutané, et décharge le sang à travers une conduite de décharge (52) communiquant librement avec une artère périphérique partant de l'arc aortique du patient via un raccordement anastomotique sous-cutané. La pompe peut fonctionner en continu ou de manière pulsatoire, en synchronisation avec le coeur du patient, ce qui permet de réduire potentiellement la charge de pompage sur le coeur.

Abstract: In office equipment such as printers and copiers, a single machine "platform" is available as a number of distinct variants (copier, printer, facsimile, MICR printer). Different variants may require different types of marking material cartridges, or other replaceable units. To prevent the installation of an unsuitable cartridge in a machine, each cartridge defines a distinguishing configuration of convex or concave engagement structures, arranged in a circle, but whereby no more than one-half of the circumference of the circle is taken up by the engagement structures. The engagement structures engage with complementary structures inside a suitable machine, and can assist in driving a rotation of the cartridge within the machine.
