Abstract: L'invention concerne un système d'évacuation de fumée utilisé pendant des procédures chirurgicales, en particulier des procédures peu invasives qui impliquent l'utilisation d'un laser ou d'un cautère, au niveau d'un site chirurgical présentant une pression associée plus élevée que la pression ambiante. Ce système comprend un filtre pourvu d'un côté site et d'un côté sortie, et un conduit de fluide qui s'étend entre le site chirurgical et ledit filtre. Ce filtre présente une faible résistance ou une faible chute de pression et résiste à un écoulement fluidique. De ce fait, la pression plus élevée que la pression ambiante n'est pas réduite et génère un écoulement fluidique dans le chemin d'écoulement fluidique, ce qui tend à véhiculer la fumée dans le filtre.

Title: Robust efficient distributed rsa-key generation
Inventor: YUNG MARCEL M
IPC: G09C1/00
Filed: 1999-05-21
Granted: 2009-10-13
Abstract: The invention provides for robust efficient distributed generation of RSA keys. An efficient protocol is one which is independent of the primality test "circuit size", while a robust protocol allows correct completion even in the presence of a minority of arbitrarily misbehaving malicious parties. The disclosed protocol is secure against any minority of malicious parties (which is optimal). The disclosed method is useful in establishing sensitive distributed cryptographic functio n sharing services (certification authorities, signature schemes with distributed trust, and key escrow authorities), as well as other applications besides RSA (namely: composite ElGamal, identification schemes, simultaneous bit exchange, etc.). The disclosed method can be combined with proactive function sharing techniques to establish the first efficient, optimal-resilience, robust and proactively-secure RSA- based distributed trust services where the key is never entrusted to a single entity (i.e., distributed trust totally "from scratch"). The disclosed method involves new efficient "robustness assurance techniques" which guarantee "correct computations" by mutually distrusting parties with malicious minority.

Abstract: A hollow expandable and contractible displacement element is secured onto the concave rear surface of a slat facing the leading edge of an aircraft wing. A bleed air line supplies engine bleed air into the hollow displacement element to selectively expand or contract the displacement element, which is preferably elastically expandable. When the slat is extended, the displacement element is expanded to fill-out the concave cavity on the rear surface of the slat so as to prevent formation of a vortex in the slat air gap and thereby to reduce aero-acoustic noise. When the slat is retracted, the displacement element is contracted to be conformingly accommodated in the sickle-shaped space between the slat and the leading edge of the wing.

Abstract: L'invention concerne un nouveau procédé permettant de regrouper des tissus de manière à la fois sûre et efficace, afin de traiter ces tissus avant de les implanter chez un receveur. Dans un mode de réalisation, ce procédé consiste tout d'abord en une perfusion d'un implant poreux, ce qui permet une interpénétration efficace des facteurs souhaités dans les pores de cet implant, ainsi qu'une élimination des facteurs nocifs de ces pores. Ce procédé consiste ensuite à nettoyer ledit implant, à le soumettre à une passivation efficace (inactivation des agents pathogènes, des micro-organismes, des cellules, des virus, et analogues, et réduction de leur antigénicité), ce traitement permettant d'obtenir le nouvel implant voulu. Ce processus est mis en oeuvre par un système dans lequel la vitesse, le déroulement, et l'amplitude de cycles de pression permettent d'obtenir des tissus efficacement nettoyés, ainsi que d'autres implants aptes à être implantés. Les valeurs de réduction à atteindre en matière de décontamination, varient, selon ce processus, entre un (1) et douze (12) pour la contamination bactérienne, environ entre un (1) et quinze (15) pour la contamination de virus à enveloppe, jusqu'à cinq (5) pour la contamination de virus non à enveloppe, et environ entre deux (2) et dix (10) pour l'endotoxine. Enfin, ce processus est destiné à entretenir l'implant ou les propriétés biologiques et biomécaniques du greffon, à éliminer toute toxicité des tissus pouvant être provoquée par les solutions nettoyantes utilisées, et à réduire l'antigénicité dudit implant.

Granted: 2010-11-30
Abstract: A search machine finds and ranks documents in a database based on a set of rules that match characteristics of the database with a natural language query. The system includes a lexicon component which may parse the query and the database into words and word stems. Thereafter, the query and documents may be vectorized such that the elements of the vector correspond to a given word stem, and the value of the element in the vector corresponds to the number of occurrences of the word in the document. The vectorized query is then compared and evaluated against each of the vectorized documents of the database to obtain a ranked list of documents from the database. The user may evaluate the documents found and provide information back to the search machine in order to adjust, for example, the ranking produced by the search machine. In this way, the search machine can fine tune its search and ranking technique to meet the user's specific criteria.

Title: Multilayer microstructures and laser based method for precision and reduced damage patterning of such structures
Inventor: DUBOWSKI JAN J
IPC: B23K26/40
Filed: 2002-04-12
Granted: 2010-08-03
Abstract: Many integrated circuits require a multilayer structure which contains layer of an organic or polymeric material with a patterned metallic layer on it. Laser patterning has many favourable characteristics but it also damages the organic or polymeric material. A novel method is disclosed that makes possible laser patterning of conductive metal electrode deposited on top of an organic and/or polymeric material without significant ablation of the organic and/or polymeric material. The method can achieve higher patterning resolution, resulting in higher quality integrated circuits. The method is based on the application of a thin coating of an inexpensive anti-reflector deposited on top of the desired metal electrode which in turn lies on the organic and/or polymeric material. The thin anti-reflecting coating allows the use of a lower fluence laser for ablation of metal layer without damaging the underlying organic and/or polymeric material.
