Patent CA-2375432-A1 (CA)
Inventor: HAGIWARA TERUHIKO
IPC: G01V3/30
Filed: 2000-04-07
Abstract: A resistivity tool (100) suitable for use in a borehole and configured to obtain a resistivity radial profile at multiple depths of investigation in a geological formation comprises a receiver pair (R1, R2) and an array of transmitters (T1-T3). The distance of each transmitter from the receivers corresponds to a particular depth of investigation into the formation. Using as few as two transmitters, the resistivity tool derives resistivity values at any number of depths of investigation, including depths of investigation that do not correspond to transmitter/receiver spacings on the tool. A measurement processor (204) combines signals received from the existing transmitters using linear interpolation, geometric interpolation, and/or other techniques to derive the resistivity measurements.

Patent CA-2382645-A1 (CA)
Inventor: LEVNER DANIEL
IPC: G02B6/124
Filed: 2000-08-04
Abstract: L'invention concerne une méthode permettant de synthétiser des super-réseaux en faisant appel à l'analyse de Fourier. Cette méthode consiste à diviser le procédé de synthèse en différents stades : synthèse d'un profil de réseau "analogique", suivie quantification et test standard utilisant la méthode de la matrice de passage et un retour d'erreur afin d'améliorer le profil du réseau, ces deux dernières étapes pouvant être interactives. Cette méthode fournit une procédure généralisée de synthèse analogique en se servant de l'approximation de Fourier et de la théorie de conception de filtres à réponse impulsionnelle finie (FIR), tout en interprétant la simple quantification du seuil comme modulateur delta-sigma "d'ordre zéro", qu'elle améliore. Cette méthode de conception d'un super-réseau pour une guide d'ondes consiste à transformer un spectre de réflectance en une représentation dans le domaine de Fourier, à synthétiser par calcul un profil d'indice de réfraction analogique à l'aide d'une transformée de Fourier et à transformer ce profil d'indice de réfraction analogique en un profil d'indice de réfraction binaire ou à plusieurs niveaux.

Patent CA-2389152-A1 (CA)
Title: Method of protecting a hollow preform for optical fibres
Inventor: WIGGS STEPHEN T
IPC: C03B37/018
Filed: 2000-09-28
Abstract: Disclosed is a method of minimizing re-wetting of a preform upon removal of the preform from the consolidation furnace and producing core cane and/or optical fiber therefrom. During removal, the consolidated preform and, in particular, the centerline aperture is exposed to a heavy inert gas, such as Argon, Krypton or Xenon. This reduces the amount of re-wetting thereby concomitantly improving attenuation of the optical fiber produced therefrom.  This method produces beneficial attenuation reductions in the 1383 nm wavelength region.
