Title: Methode de traitement
Inventor: KNOX PETER
IPC: A61P15/00
Filed: 2002-08-16
Abstract: Cette invention concerne une méthode de traitement d'une maladie de l'utérus dépendante des oestrogènes à évolution chronique, telle que l'endométriose et les fibromes utérins, chez une patiente, ledit traitement s'effectuant par administration intravaginale d'un inhibiteur de l'aromatase. Cette méthode permet d'obtenir, localement, des niveaux élevés d'inhibition de l'aromatase, et donc d'éviter quelques-uns des effets indésirables observés lorsque des inhibiteurs de l'aromatase sont administrés par voie orale. De plus, l'administration intravaginale inhibe l'apparition de lésions locales sans affecter de manière significative les niveaux de circulation produits par les ovaires. La méthode de l'invention induit des effets secondaires minimaux et offre un traitement à plus long terme que les thérapies courantes.

Inventor: PARK SUNG-WOO
IPC: H03H7/40
Filed: 2005-05-26
Abstract: A method and apparatus to automatically control a step size of a least mean squares (LMS) equalizer. An optimal step size can be selected by checking a signal to noise ration (SNR) of the LMS equalizer output according to a change in the step size. The LMS equalizer includes a step size decision block, which makes a relatively large change to the step size within predetermined upper and lower limits, and checks the SNR of the LMS equalizer output according to the change made to the step size. If the SNR becomes greater than a certain value, the step size is again adjusted with a higher precision to select an optimal step size in a given channel environment. Further, the LMS equalizer is capable of selecting an optimal tap coefficient within a shorter period of time, and a hardware system used to implement the apparatus to automatically control the step size is simple, yet optimized in a given channel environment.
