Title: Use of cross tap equalization to reduce crosstalk arising from inadequate optical filtering in a wdm optical link
Inventor: WAUGH GEOFFREY S
IPC: H04B10/158
Filed: 2001-04-09
Abstract: Improved wavelength division multiplexed optical links (10) and signal processing methods that employ cross tap equalization to reduce crosstalk arising from inadequate optical filtering. After optical filtering (11) and photodetection (12), the wavelength division multiplexed signals adjacent either side of a signal whose crosstalk is to be reduced are sampled, weight ed and are then subtracted from the signal whose crosstalk is to be reduced. Th is is done using adaptive correlation (20), performed simultaneously on all signals, each with respect to its respective adjacent channels. The present invention enables more closely spaced optical carriers to be used in the wavelength division multiplexed optical link (10).

Abstract: L'invention concerne un procédé de fabrication d'une connexion mécanique et électroconductrice entre une plaquette de circuit imprimé, ou une partie du boîtier, et un couvercle électroconducteur (couvercle métallique) en vue de réaliser un blindage électromagnétique. Les couvercles métalliques du type précité, relativement rigides, sont fixés mécaniquement par brasage sur une plaquette de circuit imprimé et offrent également, lorsque le brasage est réalisé correctement, une fonction d'écran satisfaisante. Toutefois, l'apport de chaleur élevé requis pour le brasage entraîne constamment des problèmes, dans le cas de fabrication en série, pour les composants électriques ou leur blindage, lorsqu'on a recours à la technique de recouvrement métallique précitée. L'invention a pour but de supprimer les inconvénients précités et d'améliorer les techniques de fabrication connues jusqu'à présent. En conséquence, le procédé du type mentionné est caractérisé en ce qu'une masse électroconductrice, de préférence une masse coulable, capable d'être façonnée en son état initial, est positionnée entre la plaquette de circuit imprimé et le couvercle, en ce que le couvercle est fixé sur ladite plaquette au moyen de la masse électroconductrice, et en ce qu'en même temps un contact électrique est établi entre le couvercle et la plaquette de circuit imprimé.

Title: Process and device for the optical marking of a target region of a color measuring device on a measurement surface
Inventor: PFISTER BRUNO
IPC: G01J3/46
Filed: 2002-10-17
Abstract: A two dimensional color pattern which at each point has a definite and unique color value is reproduced on a measurement surface by way of a computer controlled display device for the optical marking of a target region on the measurement surface captured by a color measuring device. The color measuring device is aimed at the measurement surface and the color value of the target region captured by the color measuring device is measured. The coordinates of the target region on the measurement surface are calculated from the measured color value and an optical marker which visually indicates the location of the target region on the measurement surface is reproduced at that location on the measurement surface as defined by the calculated coordinates of the target region. Alignment of the color measurement device is simplified and made possible without the need for laser pointers or cameras.

Title: Scalable pattern methodology for multi-carrier communication systems
Inventor: HIBEN BRADLEY M
IPC: H04L27/26
Filed: 2001-07-02
Abstract: A scalable pattern methodology defining positions of synchronization symbols, pilot symbols and data symbols for various numbers of sub-channels in a multi-carrier communication system. A base pattern (510) is defined identifying positions of data symbols, synchronization symbols and pilot symbols for a first number of sub-channels corresponding to a first bandwidth.     The base pattern is replicated or scaled to form an expanded pattern (512, 514) identifying positions of data symbols, synchronization symbols and pilot symbols for an expanded number (M) of sub-channels corresponding to a second bandwidth. The pattern methodology may be implemented by a transmitter (100) having subdivided an original information signal into M bit streams and having encoded each of the M bit streams to 16QAM symbols to form M symbol streams, by inserting synchronization and pilot symbols into each of the M symbol streams at positions determined by the expanded pattern. The pattern methodology allows a receiver (600) to perform pilot interpolation in the M symbol streams with the same set of pilot interpolation filters that would be required to perform pilot interpolation in the symbol streams of the base pattern.
