Title: Method and device for authenticating with symmetrical algorithm
Inventor: ROUSSEAU LUDOVIC
IPC: G06F21/00
Filed: 1999-08-16
Abstract: The invention concerns a method and a system for authenticating with symmetrical algorithm essentially characterised in that, for each mutual authentication of two parties, a cryptographic computation with a variable key, referred to as K', is carried out. The main steps of said method are as follows: a) party A, possessing the secret key K, sends a random number R2 to party B, the latter also possessing the same secret key K; b) party B selects a random number R2, and computes the number K', which is also a secret key, from the following formula: K' = R2 xor K, xor being the equivalent of the  exclusive or  mathematical operation; c) then, B, using a symmetrical encryption algorithm ALG, computes a result r derived from the formula: r = ALG[K'](R1); d) said party B then sends r and R2 to said party A; e) said party A, using the same symmetrical encryption algorithm ALG, computes K' and r' from the following formulae: K' = R2 xor K and r' = ALG[k'](R1); f) if r is equal to r', then said party B is authenticated by said party A.

Title: Method and system for adjusting spurious lines of an output frequency spectrum in a sideband frequency translating device
Inventor: GAMBINA MARIA LUISA
IPC: H04L27/36
Filed: 1999-10-22
Abstract: The invention concerns a method which consists in: delivering in input on two channels of the frequency translating device two parameterable and mutually phase-shifted test signals TXI and TXQ; measuring the level of each of the spurious lines for different test values of different parameters; and determining the reference values for the different parameters for minimising the levels of spurious lines, by digital computation carried out from a predetermined number of different test values and corresponding measured level values, taking into account two parabolic relationships relating the levels of two spurious lines to said parameters. Thus, the adjusting time interval is reduced to a minimum by using a reduced number of test values. The invention is applicable to mobile telephone system.

IPC: H04N19/94
Filed: 2001-01-31
Abstract: A method of compressing an image frame composed of an array of pixels in the form of digital signals comprises a two stage codebook search. In the first stage the pixelated image frame and the pixelated codebook patches are transformed to frequency domain coefficients and a pattern comparison is made between the coefficients of the image patch and the codebook patches to identify a short list of possible match codebook patches by discarding incorrectly matching patterns. In the second stage the image frame is compared with the short list of codebook patches by any desired method, e.g. by pixel comparisons, to select the best matching codebook patch.

Title: Traitement de donnees seismiques
Inventor: ZEROUK KAMIL
IPC: G01V1/36
Filed: 2003-12-03
Abstract: L'invention concerne le traitement de données séismiques qui contiennent à la fois un signal recherché et un bruit de gonflement. Le procédé est applicable aux données séismiques dans le procédé de domaine fréquence-espace et comprend la détermination un filtre de prévision de signal seulement à partir des données séismiques à une première fréquence à laquelle le bruit de gonflement n'est pas présent, et l'application du filtre de prévision aux données séismiques à une deuxième fréquence à laquelle le bruit de gonflement est présent. Ceci atténue le bruit de gonflement dans les données séismiques à la deuxième fréquence. Dans un mode de réalisation, le filtre de prévision pour une fréquence f L, la plus basse fréquence à laquelle le bruit de gonflement est présent, est déterminé à partir des données séismiques à la fréquence f H+1, où f H est la fréquence la plus élevée à laquelle le bruit de gonflement est présent. Le filtre de prévision pour une fréquence f L+1  est déterminé à partir des données séismiques à la fréquence f H+2, et ainsi de suite, de sorte que le filtre de prévision pour la fréquence f H+1  soit déterminé à partir des données séismiques à la fréquence f 2h-l+1. De cette façon, le filtre de prévision pour chaque fréquence dans la gamme de bruit de gonflement est déterminé à partir des données séismiques en dehors de la plage de bruit de gonflement, mais à une fréquence proche de la plage du bruit de gonflement, et on obtient ainsi une extraction efficace du signal et une atténuation du bruit de gonflement. En outre, aucun filtre de prévision n'est appliqué aux données de plus d'une fréquence, de sorte qu'une erreur dans la détermination d'un filtre particulier de prévision aura un effet seulement limité sur les données traitées.

Title: A canopy assembly
Inventor: CARLISLE GEORGE
IPC: B64C1/14
Filed: 1989-04-25
Abstract: A canopy assembly for an aircraft includes a forward canopy panel (2) and a rear canopy panel (4) carried by a support frame. The canopy panels (2 and 4) are mounted on the support frame (6) by buttstraps (40, 42, 44). The bottom edges of the forward canopy panel (2) and the rear canopy panel (4) are set in a bed of sealing compound. A bed of a release agent prevents adhesion between the front part of the forward canopy panel (2) and the bed. The canopy panels (2 and 4) are attached to one another at a central region by internal and external buttstraps (56 and 58). The adjacent parts of the panels (2 and 4) are contained in beds of sealing compound, and a release agent is applied to said adjacent parts. The rear edge of the canopy panel (2) and the front edge of the canopy panel (4) are scalloped adjacent each clamping bolt. In the event of a birdstrike the forward canopy panel (2) deforms and moves locally rearwardly with respect to the aircraft fuselage. The central buttstraps may also move locally rearwardly with respect to the aircraft fuselage and rear panel (4).

Abstract: Un procédé en continu de production d'éthers cycliques à substitution nitratoalkyle consiste à (a) mélanger simultanément un courant de N2O5 et un courant d'un éther cyclique à substitution hydroxyalkyle dissous chacun dans un solvant organique inerte, puis (b) à séparer rapidement les coproduits d'acide nitrique et le nitroalkyle avant qu'ils ne puissent réagir ensemble pour rompre l'anneau d'éther. On procède avantageusement à l'étape (b) en refroidissant rapidement le courant de produit dans approximativement les 15 secondes suivant sa formation, dans une solution aqueuse basique dans laquelle l'acide nitrique est transféré à partir de la phase organique et est neutralisé. On peut citer à titre d'exemples de produits que l'on peut préparer à l'aide de ce procédé les oxiranes et oxétanes à substitution nitratroalkyle.

Filed: 1989-08-22
Abstract: Un tableau de distribution électrique comprend dans une relation spatiale fixe, un rail DIN constitué par une paire d'éléments de rail séparés constituant les bords fonctionnels du rail DIN et d'une barre bus. Le rail DIN et la barre bus servent à monter un dispositif de protection électrique (tel que par exemple un MCB). Un des éléments de rail du rail DIN est mobile de manière pivotante d'une position d'engagement dans une formation de localisation d'un dispositif de protection électrique afin de permettre le montage facile du dispositif sur le tableau de distribution, ou le retrait de celui-ci, sans qu'il faille débrancher la barre bus du tableau. On évite ainsi les difficultés connues de montage et de démontage des dispositifs de protection de circuits montés sur rail DIN en présence d'une barre bus fixe dans des ensembles réalisés en usine.
