Patent CA-2321748-A1 (CA)
Title: Procede et systeme d'acces multiple
Inventor: SHATTIL STEVEN J
IPC: H04B1/7115
Filed: 1999-02-10
Abstract: L'invention concerne un système de communications sans fil permettant d'émettre simultanément des données sur plusieurs porteuses, afin de fournir une diversité de fréquence. Les parasites entre ces porteuses provoquent une impulsion étroite dans le domaine temporel lorsque les phases relatives de ces porteuses sont égales à zéro. On choisit la séparation des fréquences et les phases des porteuses de manière à régler la synchronisation d'impulsions, la répartition temporelle des impulsions et la séparation des fréquences desdites porteuses offrant ainsi un accès multiple. L'interférométrie de ces porteuses constitue une base à partir de laquelle il est possible de dériver d'autres protocoles de communication. Les sauts et le déplacement de fréquence desdites porteuses ne modifie pas l'enveloppe des impulsions si la relative séparation des fréquences et les relatives phases entre les porteuses sont maintenues. On produit des signaux CDMA en séquence directe dans un domaine temporel en choisissant de manière prédéfinie les amplitudes des porteuses, chaque impulsion pouvant être échantillonnée dans différents espaces de phase à différents moments, ce qui permet à des communications de se dérouler dans des espaces de phase ne pouvant être détectés par des récepteurs traditionnels. La relation de phase asservie au temps desdites porteuses permet en outre un balayage automatique d'un diagramme de rayonnement émis par un groupement d'antennes. Dans des communications par guide d'ondes, les fréquences et les phases des porteuses peuvent correspondre à la dispersion chromatique d'une fibre optique, afin d'augmenter la capacité de cette fibre.

Title: A method of timing calibration
Inventor: BARROSO CHRISTOPHER BURKE
IPC: G01C21/00
Filed: 2000-10-30
Abstract: Dislosed is a method for deriving accurate global positioning satellite (GPS) timing by calibrating frame boundaries to GPS timing. Time calibration is achieved by determining a time difference .DELTA.~ between a reference GPS time (or pulse) and an ~th frame boundary. The time difference .DELTA.~ and a frame boundary identifier specifying the ~th frame boundary are provided to a device equipped with a full or partial GPS receiver so that the GPS equipped device may synchronise itself to GPS timing. Upon synchronizing itself to GPS timing, the GPS equipped device may search for GPS signals using information by a geographical location server, e.g., WAG server.

Abstract: In a method for contactless online measuring of the wall thickness of hot-rolled pipes in the hot state for determining undesirable inner wall structures, at least one measuring head, operating according to the laser ultrasound method, scans a segment of a wall of a pipe to be measured in a circumferential direction during or directly after a rolling process. The course of the wall of a cross-section of the pipe is then reconstructed with a computer. The measuring head is a compact laser ultrasound measuring head adjustable relative to the pipe dimension to be measured. It has an excitation laser and an illumination laser and optical elements for collecting a carrier light containing the ultrasound signal and reflected at a surface of the pipe. The excitation and illumination lasers and the optical elements are arranged in a common housing of the measuring head. A pivot device is provided to pivot the laser ultrasound measuring head across a segment of the pipe in the circumferential direction.
