Title: Method and device for calculating computer file signatures
Inventor: UGON MICHEL
IPC: G07F7/10
Filed: 1994-03-30
Granted: 1999-02-23
Abstract: The invention relates to a method of signing a main computer file (FP), of the type consisting in making circuits of an information processing device (1,3,4) calculate at least one signature (SG) of the file, taking into account at least one secret data item (S; Sd) specific to the signatory, but unknown to the latter, memorised in a secret memory area of a portable electronic object (4), with a memory and processing circuits, available to the signatory, and in linking the calculated signature to the main file. It is characterised in that, upon the calculation of each signature, it further consists in taking account of at least a part of the main file, so that the signature is a function of the secret data item of the signatory and of each part of the file taken into account, and in creating a secondary file (FS) and in writing therein at least some information (IN) making it possible to identify each part of the main file having served for the calculation of this signature, and in linking the secondary file, on the one hand to the corresponding signature, and, on the other hand, to the signed file. <IMAGE>

Title: Frequency synchronized bidirectional radio system
Inventor: DAVIDOV MIRCHO A
IPC: H04L7/033
Filed: 1993-01-08
Granted: 2003-07-29
Abstract: A bidirectional radio system for low cost, high through-put accumulation of data from a large number of site units. The site units are connected to remote radio transceivers in radio communication with a plurality of base stations (44). Accurate frequency synchronization allows multiple carriers within a 12.5 kHz FCC bandwidth.  Frequency synchronization is achieved at !ow cost by transmitting a high accuracy carrier and clock signal at a base station, and using receiving circuitry (54) at remote stations to ex-tract the base clock signal and base carrier frequency and a phase-lock loop (258 and 248) to stabilize the remote station carriers. The reception circuitry at a remote station provides independent carrier frequency and clock rate recovery, a phase-lock loop at baseband, and a coarse clock rate recovery circuit (316) coupled to a fine clock rate recovery circuit (320). Remote station re-sponses are time domain multiplexed. A base station receiver can decode a very short remote station response by scaling the re-sponse with the phase and amplitude of an initial segment of the response.  Spatial reuse of carrier frequencies further increases the rate of data throughout.

Abstract: A structural device is attached to each sideframe pedestal jaw of a railcar truck wherein the bearing adapter is joined to the sideframe and is prevented from rotating within the pedestal jaw opening. The bearing adapter inboard and outboard faces maintain a parallel relationship with the sideframe inboard and outboard faces during operations, including curving, thereby causing the truck axles to remain at a right angle with respect to the sideframes. Maintaining this right angular relationship substantially curtails truck wheel misalignment, which directly effects truck hunting and curving.

Abstract: Procédé et dispositif permettant de vérifier l'état d'un ou plusieurs joints à l'intérieur d'un raccord fileté (12) de matériel tubulaire pour champs pétrolifères. On peut utiliser un dispositif de contrôle (74) comprenant trois détecteurs espacés axialement les uns des autres (92, 86 et 88), chacun étant sensible à la déformation radiale d'une surface externe (52) d'un raccord fileté sous pression intérieure (12). Une déformation radiale excessive indique le défaut d'au moins un des joints filetés (48, 54, 56,58). Une technique relativement simple et extrêmement fiable permet de déterminer rapidement et facilement l'état d'étanchéité d'un raccord fileté (12) réalisé sur un site de forage. Si l'un ou l'autre des joints multiples (48, 54, 56, 58) est défaillant pendant la vérification, le technicien peut soit ouvrir et recontrôler le raccord, soit réaliser et contrôler un nouveau raccord fileté (12).
