Title: Method and apparatus for analyzing one or more firewalls
Inventor: MAYER ALAIN JULES
IPC: H04L29/06
Filed: 2000-12-12
Abstract: A method and apparatus are disclosed for analyzing the operation of one or more network gateways, such as firewalls or routers, that perform a packet filtering function in a network environment. Given a user query, the disclosed firewall analysis tool simulates the behavior of the various firewalls, taking into account the topology of the network environment, and determines which portions of the services or machines specified in the original query would manage to reach from the source to the destination. The relevant packet-filtering configuration files are collected and an internal representation of the implied security policy is derived. A graph data structure is used to represent the network topology. A gateway-zone graph permits the firewall analysis tool to determine where given packets will travel in the network, and which gateways will be encountered along those paths. In this manner, the firewall analysis tool can evaluate a query object against each rule-base object, for each gateway node in the gateway-zone graph that is encountered along each path between the source and destination. A graphical user interface is provided for receiving queries, such as whether one or more given services are permitted between one or more given machines, and providing results. A spoofing attack can be simulated by allowing the user to specify where packets are to be injected into the network, which may not be the true location of the source host-group.

Title: Phosphating compositions and processes and products therefrom with improved mechanical formability
Inventor: GOODREAU BRUCE H
IPC: C23C22/22
Filed: 1999-05-07
Abstract: When a phosphate ester or a dispersed wax is added to a conventional liquid phosphate conversion coating composition, the resulting phosphate coating formed on a metal substrate has a lower coefficient of friction after being oiled than it would have had if the additive had been omitted. The corrosion resistance and paint adhesion properties expected from the conversion coating are not substantially diminished by the additive. Particularly good results are achieved if the phosphate coating composition contains calcium and ferrous cations and the liquid phosphate conversion coating composition is dried into place on the substrate.

Abstract: L'invention concerne un format amélioré destiné à la génération d'empreintes de pharmacophores, ainsi que des méthodes permettant de générer et d'utiliser lesdites empreintes. Dans un mode de réalisation préféré, la relation structure-activité est dérivée au moyen d'empreintes de pharmacophores. Une empreinte de pharmacophores pour un certain composé chimique peut définir une collection de différents pharmacophores correspondant à la structure dudit composé. De préférence, l'empreinte est constituée de pharmacophores distincts qui correspondent à des conformations favorables sur le plan énergétique. Certains pharmacophores peuvent correspondre à une première conformation, mais pas à une seconde, tandis que d'autres peuvent correspondre à la seconde conformation, mais pas à la première. Pourtant, les deux conformations sont susceptibles d'apporter une contribution importante à l'activité du composé. L'empreinte doit donc identifier les pharmacophores correspondant à toutes les conformations appropriées. L'invention concerne également un dispositif et des techniques qui permettent d'identifier, de représenter et d'utiliser de manière productive les régions à forte activité d'un espace chimique. De nombreuses représentations d'espace chimique ont été utilisées et peuvent être envisagées. Dans un mode de réalisation préféré de la présente invention, au moins deux représentations fournissent des informations intéressantes. Dans la première, plusieurs dimensions sont définies par un ensemble de pharmacophores de base et par une ou plusieurs dimensions supplémentaires représentant une activité chimique définie (par exemple, une activité pharmacologique). Dans une seconde représentation, de dimensions réduites, les coordonnées peuvent être dérivées de la première représentation par une technique mathématique appropriée, telle que les composantes principales produites par l'analyse en composantes principales, utilisant les données des empreintes des pharmacophores/de l'activité pour une collection de composés.

Title: Systeme et methode de gestion de profils personnels pour plusieurs organismes
Inventor: DESJARDINS DANIEL
IPC: G06Q10/10
Filed: 2001-07-13
Abstract: Le système et la méthode servent à la gestion de profils personnels d'usagers pour le compte de plusieurs organismes. Leur but est d'effectuer un traitement en commun d'informations contenues dans les profils personnels d'usagers. Une première interface web est fournie afin de préparer une requête pour obtenir une clé d'identification unique. Une fois complétée par un usager, la requête est reçue à un serveur qui la traite et envoie la clé d'identification unique à l'usager si celui-ci est qualifié pour la recevoir. Une deuxième interface web est alors fournie afin de permettre aux usagers d'y inscrire des informations au sujet de leur profil personnel. La deuxième interface web inclut une section générale commune à tous les organismes, et au moins une section spécifique qui n'en concerne que certains. Les informations complétées sont ensuite sauvegardées dans la base de données. Le système et la méthode comprennent de nombreux avantages pour l'usager, notamment le fait qu'un même formulaire lui permet d'inscrire son profil personnel auprès de chacun des organismes visés. II en résulte donc notamment une économie de temps appréciable au niveau de l'entrée des données puisqu'il évite d'avoir à compléter de multiples formulaires.  L'invention permet aussi de diminuer, voire d'éviter, des erreurs de saisies de données. Beaucoup d'autres avantages découlent de ce système et de cette méthode.
