Patent EP-1347611-A1 (EP)
Inventor: VENTURA ALESSANDRO
IPC: H04L27/233
Filed: 2002-03-20
Abstract: Some improvements to the conventional algorithms for data aided frequency
synchronisation in cellular systems are introduced in a new method executable by the
user equipments of various standards, i.e. 3GPP CDMA-TDMA, FDD mode at 3.84
Mcps, TDD mode at 3.84 Mcps, TDD mode at 1.28 Mcps; CWTS TD-SCDMA;
GSM/DCS/GPRS. The method begins to obtain the suboptimal frequency errors Δ 
using a well known formula which calculates the argument of the autocorrelation over a
subset of the baseband samples of the detected training sequence. The errors Δ    are
stored into a shift register  L -position long and averaged to obtain an estimated
frequency error Δ f and i    used for recursively correcting the reference frequency of the local
oscillator, as:  f and i    =  f and i     -1  +  K Δ f and i    where  K  (0 ≤  K  ≤ 1) is a weighting factor. Contrarily
to the simple averaged error of the prior art, a sign criterion is used by which the
average is performed on the only terms having the most recurrent algebraic sign
among the stored terms Δ   . The content of the shift register is corrected after each
non-null frequency correction by subtracting  K ·Δ f and i    to all the stored terms Δ   .
Besides the frequency is corrected upon the following optional conditions, each other
independents: The number of terms Δ    having equal algebraic sign is greater than a
constant α lower than  L.  The standard deviation σ of the averaged terms Δ    is
lower than β·σ   old   , being  σ old    the σ of the last non-null frequency correction, and
β a constant ≥ 1. After a minimum number γ of iterations between two non-null
frequency corrections are spent, being γ a constant comprised between 1 and  L. 
According to another variant the iterations of the recursive update are subdivided into
an initial group with a higher  K  value for achieving fast convergence and a
subsequent group with a lower  K  for achieving the required accuracy (fig. 13).

first image into a plurality of pixel blocks,   assigning (Block_Weight) to each block of the
plurality a respective weighting coefficient calculated
on the basis of a respective inhomogeneity measure,   estimating (GMV_Select) the at least one
motion vector ( F_GMV, B_GMV ) of said at least one region
(F_Ground, B_Ground) on the basis of the weighting
coefficients assigned to each block of the at least one
region.

Abstract: Cette invention porte sur un procédé et un compteur visant à réduire le taux de comptage du fond naturel de rayonnement dans des compteurs de particules alpha à gaz, lequel compteur est conçu de manière à accentuer les différences des caractéristiques des impulsions d'un préamplificateur (11 et 111) générées par le captage des charges dans des courants d'ionisation (23) créés par les particules alpha émanant de différentes zones à l'intérieur du compteur (50), puis à utiliser l'analyse des caractéristiques des impulsions pour identifier ces différences et ainsi différencier les différentes zones d'émission (6). Les particules alpha émises par l'échantillon peuvent ensuite être comptées alors que celles émises par des composants du compteur sont rejetées, ce qui permet d'obtenir de très faibles taux de comptage du fond naturel de rayonnement, même avec des grands échantillons. Une électrode (33) de garde peut être placée autour du périmètre (205, 200) de l'anode et une deuxième analyse des caractéristiques des impulsions peut être effectuée sur les impulsions de signaux produites par un préamplificateur (11) relié à cette électrode de garde pour que les particules alpha émises par les parois latérales (26) du compteur soient identifiées et rejetées afin de réduire encore le fond naturel de rayonnement du compteur.

Abstract: L'invention concerne un procédé uniforme et contrôlable permettant de rugosifier électrochimiquement une surface comprenant de l'aluminium à utiliser dans un appareil de traitement à semi-conducteur. La surface comprenant l'aluminium est normalement en aluminium ou en alliage d'aluminium. Le procédé consiste à immerger une surface comprenant de l'aluminium dans une solution HCl présentant une concentration oscillant entre environ 1 volume en % et environ 5 volumes en % à une température comprise entre environ 45° C et environ 80° C, puis à appliquer une charge électrique ayant une densité de charge oscillant entre environ 80 amps/ft.2 et environ 250 amps/ft.2 pendant une période de temps allant d'environ 4 minutes à environ 25 minutes. Un agent chelateur peut être ajouté afin d'améliorer le procédé de rugosification. Le procédé de rugosification électrochimique peut être utilisé sur des alliages d'aluminium en règle générale, entre autres 6061 et LP. La rugosification électrochimique permet d'obtenir une surface de laminage lisse n'encapsulant pas de particules et offrant une zone de surface plus grande en vue d'une adhérence de sous-produit semi-conducteur.
