Abstract: Procédé de rectification de la surface du flanc de dents de roue dentées par enlèvement contrôlé de matière d'une roue dentée à l'aide d'un outil. Selon le procédé on utilise une machine à tailler les roues dentées dans laquelle l'outil (42) et la roue dentée (50) à rectifier sont mobiles l'un par rapport à l'autre le long et autour de plusieurs axes. La machine théorique de base comporte une série de réglages permettant de positionner et mouvoir l'outil (24) et l'engrenage (26) l'un par rapport à l'autre. Chacun des réglages de la machine est du type réglage actif, et chacun des réglages actifs est représenté par une fonction. La rectification désirée du flanc d'une dent est déterminée et définie par un ensemble de coefficients pour chacun des réglages actifs. Pour chacun des réglages actifs la fonction est alors déterminée sur la base des coefficients respectifs de chacun des réglages actifs, puis les fonctions sont transformées pour passer de la machine théorique au système d'axes de la machine de production. Du fait de cette transformation, les mouvements correspondant aux réglages actifs définis sur la machine théorique sont exécutés suivant un ou plusieurs des axes de la machine de production pour enlever de la matière de la roue dentée (50) à l'aide de l'outil (42) selon les fonction de réglage actif de la machine de base.

Abstract: A process and device (24) for triggering a measurement process for evaluating the quality of audio and/or speech signals enable field measurements to be carried out to determine the quality of a digital transmission. During a first step, digital values of a reference signal underlying at least part of a test signal whose quality is to be evaluated are stored. Digital values of the test signals are also at least temporarily stored. The degree to which a section of the reference signal values coincides with the test signal values is determined to trigger the measurement process as soon as a predetermined degree of coincidence is exceeded, in order to compare a further section of the reference signal values to the test signal values in the relative position in time of the reference signal and test signal values at the moment when a predetermined degree of coincidence occurs.

Title: Method and apparatus for performing decoding of codes at variable data rates
Inventor: STEIN JEREMY M
IPC: H03M13/00
Filed: 1997-09-11
Granted: 2006-01-31
Abstract: The present invention is a novel and improved method and apparatus for decoding a frame of digital data which contains redundant information provided to validate the decoding operation. In the present invention, a frame of data contains information bits and cyclic redundancy check (CRC) bits. The received frame is decoded and a check is conducted by CRC check (84) to determine whether the CRC bits correspond correctly for the decoded information bits. If the decoded frame passes the CRC test process, the decoded frame is provided to the user. However, if the decoded frame does not pass the CRC test, then at least one additional decoding process is performed on the received frame. In the first exemplary embodiment of the present invention, if the CRC test is failed, a noise vector of a predetermined set of noise vectors generated by noise generator (80) is summed with the received frame and the resultant frame is decoded for a second time. In the second exemplary embodiment of the present invention, when the CRC test fails, a set of the received symbols are replaced with symbol erasure indications by erasure generator (162).

Abstract: Composition en microcapsule à masquage de goût pour l'administration d'un médicament. Plusieurs microcapsules renferment un médicament et une matière polymère sensiblement insoluble dans l'eau, généralement de type polymère cellulosique. Il est possible d'intégrer la composition à un nombre non limité de préparations pharmaceutiques, notamment les comprimés à mâcher, les comprimés effervescents, les poudres, les dispersions liquides et autres. On décrit aussi un procédé relatif au masquage du goût des médicaments, qui repose sur une technique de séparation-coacervation de phase, pour l'enduction d'un médicament avec des niveaux relativement élevés de matière polymère. Ces niveaux élevés d'enduction conduisent à un masquage efficace du goût, sans toutefois nuire à la libération ciblée du médicament, lequel est ainsi libéré peu après son passage dans la cavité buccale.
