Patent CA-3058708-A1 (CA)
Inventor: DREW THOMAS
IPC: G01M11/02
Filed: 2017-10-17
Abstract: L'invention concerne l'affichage sur une surface plane d'un motif de test (170) comprenant un ensemble de points (174) qui définissent une première ellipse (176) de meilleur ajustement dans laquelle les axes majeur et mineur R1, R2 sont égaux (à savoir, un cercle) et la capture d'une image numérique du motif de test (généralement déformé) vu à travers un verre. Une seconde ellipse de meilleur ajustement joignant les points de l'ensemble est dérivée du motif de test déformé de l'image. Des caractéristiques des première et seconde ellipses sont comparées pour déterminer le degré et la nature de la distorsion du motif de test, à partir desquels est calculée la puissance du verre. Les axes majeur et mineur des première et seconde ellipses peuvent être comparés. Le motif de test peut comprendre un certain nombre desdits ensembles de points répartis sur une zone de la surface, chaque ensemble étant analysé pour déterminer les paramètres optiques du verre au niveau de multiples positions.

Title: Near-end crosstalk cancellation
Inventor: LINNEY DAVID W
IPC: H04L25/08
Filed: 2017-05-05
Abstract: The present disclosure relates to near-end crosstalk (NEXT) cancellation. A transmit communication signal is transmitted over a first Digital Subscriber Line (DSL) connection using a first group of frequencies and a receive communication signal is received over a second DSL connection using a second group of frequencies that at least partially overlaps the first group of frequencies.
