Abstract: A seal assembly (100) for reception of an elongated surgical instrument (110) is provided which includes housing components (114, 116) having at least one opening configured, dimensioned to permit entry of an elongated surgical instrument (110), and defining a central longitudinal axis. The seal assembly (100) further comprises a seal member (118) formed of a resilient material and defining an aperture therein, the aperture being configured and dimensioned such that insertion of the surgical instrument (110) into the aperture causes the resilient material defining the aperture to resiliently contact the outer surface of the surgical instrument (110) in a substantially fluid tight manner; and a fabric layer (128) juxtaposed relative to the resilient material. A coating (418) may be applied to seal member (118) to reduce friction between seal member (118) and surgical instrumentation (110) inserted therein. The coating (418) is preferably a hydro-cyclo-siloxane membrane deposited by plasma polymerization process.

Abstract: A method and an embedded system for verifying a request to certify a public key (Kp) generated by an embedded system with the identifier (SN i). For a set (Lk) of embedded systems, an authorized operator with the identifi er (OP j) configures the embedded systems and creates (1001) a mother public key (KpM) and a mother private key (KsM). The identifier (OP j), the range of identifiers referenced (Lk) and the mother public key (KpM) are published (1002). For each embedded system ( SN i), a diversified key (KsM i) is created from the identifier (SN i) and stored (1003) in read- and write-protected storage. For every public key (Kp) generated by an embedded system, a cryptographic control value (Sc i) is calculated (1006) on the public key (Kp), an algorithm identifier (CA1) and the utilization parameters (U) of this key, using a zer o knowledge signature algorithm, and a certification request message (MRCA) that include s the control value (Sc i), the identifier of the operator (Op j), and the identifier (SN i) is transmitted to a certification authority, which retrieves the identifier (Op j) (1009) and th e value of the mother public key (KpM) (1011). A verification (1012) of the message (MRCA) from th e mother public key (KpM) and from the identifier of the embedded system (Sn i) makes it possible to be sure that the request to certify a public key (Kp) and the utilization of the latter actually originates from an embedded component capable of limiting the use of this ke y.

Abstract: L'invention concerne un procédé de fabrication de sels alcalins légèrement ou très peu solubles d'hétérocycles sulfinyle substitués renfermant une fraction imidazole de formule (I), de préférence des sels alcalins d'un composés inhibiteur de pompe à protons. Ledit procédé consiste à faire réagir l'hétérocycle sulphinyle substitué de formule (I) avec une source de cations en présence d'une base. Ledit procédé est caractérisé en ce qu'il comporte une opération de lavage, au cours de laquelle le sel alcalin préparé à partir du composé hétérocycle sulphinyle substitué est lavé à l'aide d'un mélange de solvants aqueux basique. La substance médicamenteuse en vrac obtenue permet d'obtenir un produit en vrac dont le pH, dans une suspension aqueuse de l'hétérocycle sulphinyle substitué, n'est pas sensiblement inférieur à celui d'une solution aqueuse saturée du composé pur préparé. Selon un autre mode de réalisation, le procédé de fabrication d'une forme posologique pharmaceutique comprenant la substance active peut être ajusté. Par exemple, la pH d'une suspension aqueuse de la substance active est ajusté à un pH qui n'est pas sensiblement inférieur à celui d'une solution aqueuse du composé pur. Les procédés sont, de préférence, utilisés dans la fabrication d'un sel omeprazole-magnésium ou d'un sel de magnésium de l'un de ses énantiomères simples utilisés dans les formes posologiques pharmaceutiques.

Title: Systeme de transformation pyroelectrique
Inventor: IKURA MICHIO
IPC: G01J5/34
Filed: 1998-12-14
Granted: 2005-08-02
Abstract: Lorsque la température d'un film pyroélectrique augmente, pour passer d'une température basse à une température élevée, proche de sa température de transition de phase, sa capacité à maintenir une charge électrique sur sa surface diminue, et la charge peut être débitée comme un courant par une résistance de charge externe. Dès que la température du film atteint une valeur stable, le courant cesse d'être débité. Toutefois, lorsque la température du film est abaissée de nouveau, elle confère une nouvelle charge sur les surfaces du film, et le processus de transformation pyroélectrique peut se répéter. Ce type de transformation dépend du degré de changement de température et de la vitesse de répétition du procédé, par conséquent, plus la succession de cycles est rapide, plus la quantité d'énergie pouvant être générée par la transformation de chaleur en énergie électrique est importante. L'invention a pour objet un appareil et un procédé permettant de transformer la chaleur en énergie électrique avec un empilement de films pyroélectriques minces, en plusieurs couches. La surface du film pyroélectrique est soumise à des cycles alternatifs de températures élevées et de températures faiblesar le déplacement de fluides à température élevée et de fluides à basse température sur sa surface. Le système fait alterner le fluide chaud et le fluide froid sans inverser le sens d'écoulement des fluides sur les films, ce qui permet d'obtenir une succession de cycles thermiques rapide avec cet écoulement de fluide unidirectionnel. Un contrôleur de tension asservi par rapport à un contacteur de proximité magnétique fixé sur un contrôleur d'écoulement rotatif, assure la synchronisation de la succession de ces cycles thermiques et électriques des films pyroélectriques.

Abstract: For the exploitation of the resources such as lumbering, there are many locations to which temporary access is desired hut to which permanent roads would not be apropriate. In the past, temporary roads have been made of gravel or the like.    However, such gravel roads are time consuming to build and maintain and are particularly costly especially in light of their temporary nature. Furthermore they may eventually damage the area upon which they are built. Still further the surface being formed is sometimes incapable of supposing the transport vehicles and the use of conventional road building materials and technique is impractical. The proposed method allows for the production of so-called snowroads through a set of relatively simple steps which can be relatively easily performed by conventional earth moving equipment without requiring special skills and through energy efficient processes. Also the proposed method provides road building capacities at a relatively low cost and with considerable time savings.
