Title: Technique et appareil de suppression de l'echo provenant d'un terminal mobile
Inventor: TRUMP TONU
IPC: H04M3/18
Filed: 1998-11-27
Granted: 2006-06-06
Abstract: Cette invention concerne une technique et un appareil d'un type nouveau qui permettent de supprimer les échos provenant d'un téléphone mobile numérique au moyen d'un annulateur d'écho (10) implanté dans le réseau. Se trouve ainsi résolu un problème pratique d'écho auquel de nombreux opérateurs de téléphones mobiles sont depuis longtemps confrontés. Cette technique fait appel à un algorithme qui diffère sensiblement d'un algorithme classique d'annulateur d'écho compte tenu des considérations fondamentales suivantes prises en compte pour cette solution: (1) l'algorithme ne doit pas compromettre la qualité vocale des appareils mobiles non générateurs d'échos (30); et (2) le trajet d'écho n'est pas linéaire grâce à la présence de paires de codeurs-décodeurs à double parole dans le trajet de l'écho et d'un faible niveau (38) d'écho.

Granted: 2009-09-08
Abstract: L'invention concerne un téléphone portatif (236) pouvant assurer un fonctionnement non onéreux comme téléphone sans cordon dans une configuration de micro-cellule établie par une micro-station de base (202), ou un fonctionnement flexible comme téléphone cellulaire en dehors de la micro-cellule, c'est-à-dire lorsque ce téléphone est desservi dans une configuration de macro-cellule établie par une macro-station de base (204) exploitée sur la même fréquence. Lorsqu'un téléphone mobile (222), desservi par la macro-station de base (204), passe au voisinage, les signaux de la micro-station de base (202) (destinés au téléphone portatif (236)) noient les signaux de la macro-station de base (204). L'invention permet de résoudre ce problème de la manière suivante : la micro-station de base (202) reçoit, retarde et retransmet (sur un cycle de travail à 50 %, soit la moitié du temps en réception et l'autre moitié en retransmission) tous les signaux émis par la macro-station de base (204), en plus de la transmission de son propre signal. Le retard apparaît à la station mobile (222) comme étant un retard à trajets multiples qui peut être résolu, moyennant quoi ladite station reste capable de recevoir le signal qui lui est destiné.

Abstract: A first filter (2061 in Fig. 1) calculates a long-time average of first change quantities based on a difference between a line spectral frequency of an input voice signal and a long-time average thereof. A second filter (2062 in Fig. 1) calculates a long-time average of second change quantities based on a difference between a whole band energy of the input voice signal and a long-time average thereof. A third filter (2063 in Fig. 1) calculates a long-time average of third change quantities based on a difference between a low band energy of the input voice signal and a long-time average thereof. A fourth filter (2064 in Fig. 1) calculates a long-time average of fourth change quantities based on a difference between a zero cross number of the input voice signal and a long-time average thereof. A voice/non-voice determining circuit (1040 in Fig. 1) discriminates a voice section from a non- voice section in the voice signal using the long-time average of the above-described first change quantities, the long-time average of the above-described second change quantities, the long-time average of the above-described third change quantities, and the long-time average of the above-described fourth change quantities.

Title: Method of determining radioactive nuclides
Inventor: HASHIMOTO TETSUO
IPC: G21C17/00
Filed: 2001-06-04
Granted: 2008-10-28
Abstract: A method of simply and quickly determining .alpha.-ray releasing nuclides having long half-life without carrying out a chemical separation is provided. By inputting a data of pulses incident to an .alpha.-ray detector in a computer, obtaining time distribution of the incident pulses by using a very short time measuring timer and plotting, and fitting the linear originated in a random event corresponding to the background and the non-linear originated in the correlated events of parent nuclides- progenies by using the least squares method, the whole generating probability P (t) from the parent nuclide to the progeny thereof is obtained. By subtracting the random events portion from the P(t), the correlated events portion is extracted. The radioactivity per unit can be obtained by dividing the extracted correlated events portion by the measured time, the amount of the supplied sample and the counting efficiency. Also, by determining nuclides unnecessary for the measurement by this method and removing the determined nuclides from the energy spectra of objective nuclides to thereby lower the background, the objective nuclides can be determined by using pulse-height discrimination.

Abstract: L'invention concerne un procédé amélioré de traitement de l'eau, qui consiste à soumettre l'eau à traiter contenant des matières dangereuses, telles qu'une dioxine ou des BPC, à un traitement à l'ozone, en plaçant ladite eau au contact de fines bulles d'ozone présentant un diamètre moyen compris entre 0,5 et 3 microns. Le procédé consiste ensuite à combiner le traitement à l'ozone avec un traitement au peroxyde d'hydrogène et/ou un traitement aux rayons ultraviolets et/ou un traitement électrolytique et/ou un traitement réalisé avec un matériau filtrant carboné. Ce traitement à l'ozone, ou combinaison de traitements, peut être utilisé pour atteindre un résultat escompté de traitement de l'eau, lequel résultat est difficile à obtenir par un procédé classique dans lequel l'ozone ou le peroxyde d'hydrogène est simplement mélangé avec l'eau à traiter. En particulier, la combinaison de traitements produit un meilleur résultat de traitement de l'eau.
