Abstract: The present invention relates to a method and an apparatus for compensating for polarization mode dispersion in an optical transmission line (9, 9') with transmission characteristics that are dependent on polarization, in particular in optical fibres and cables with not only random but also with preferred double refraction. A compensation element(1, 1', 1"), preferably a double refracting fibre that contains polarization is incorporated ahead of or after the transmission line (9,9'), and the length of this is balanced by non-destructive means using an interference device (2, 2', 2"), in particular a pressure mechanism. Because of the interference, the polarization states P L and P S are mixed and this defines the length of the compensation fibre on which a delay time difference between the partial waves with polarizations P L and P S is built up or broken down, this compensating for the delay time difference T within the transmission line (9, 9')

Abstract: La gestion ou l'application des règlements de la circulation est effectuée à travers l'utilisation d'un transpondeur de surveillance dans les environs d'un système RF de collecte de péage autoroutier. Lorsque les transpondeurs en exploitation normale communiquent avec un système de lecteur de bord de route, le système de bord de route communique avec le transpondeur de surveillance qui, à son tour, envoie des signaux si un transpondeur normal valide est détecté. Si aucun signal n'est généré par le transpondeur de surveillance, il est évident que le véhicule n'a pas de transpondeur ou alors que le transpondeur est défectueux ou non valide.

Abstract: Cette invention a trait à un sac extensible à soufflets fait d'une feuille plastique dont chaque soufflet de panneau avant (64, 66) est rattaché à un soufflet de panneau arrière, chacun des soufflets de panneau pouvant se plier entre le panneau avant (63) et le panneau arrière pour constituer une périphérie sans discontinuité. Le fond du sac est rattaché à la perpendiculaire aux parois du sac, savoir aux panneaux avant et arrière, aux deux soufflets du panneau arrière et aux deux soufflets du panneau avant, seul le haut du sac (62) n'est pas fermé. L'amélioration apportée à ce sac en matière plastique repose sur l'existence de huit premiers axes de pliage linéaire adjacents au fond. Un axe de pliage linéaire se trouve dans le panneau avant, chaque soufflet de panneau avant, le panneau arrière et dans chaque soufflet de panneau arrière. Chaque axe de pliage s'étend de la jonction d'un soufflet au niveau du fond jusqu'à un bord latéral du panneau avant ou du panneau arrière et du soufflet du panneau avant ou du panneau arrière à un angle d'environ 45 DEG . Ces axes de pliage sont exécutés au moyen d'un procédé relevant d'un nombre restreint de techniques, en l'occurrence, soudure par pression à froid et constitution d'une région charnière dans la feuille plastique lorsque cette feuille est plate. Au niveau de l'ouverture de ce sac extensible à soufflets, la soudure de fond du sac adjacente aux soufflets forme un chevauchement triangulaire relativement aux soufflets, ce qui donne lieu à un sac à fond plat.

Title: Multiprocessor computer architecture incorporating a plurality of memory algorithm processors in the memory subsystem
Inventor: HUPPENTHAL JON M
IPC: H03K19/173
Filed: 1998-12-03
Granted: 2006-07-18
Abstract: A multiprocessor computer architecture incorporating a plurality of programmable hardware memory algorithm processors ("MAP") in the memory subsystem. The MAP may comprise one or more field programmable gate arrays ("FPGAs") which function to perform identified algorithms in conjunction with, and titly coupled to, a microprocessor and each MAP is globally accessible by all of the system processors for the purpose of executing user definable algorithms. A circuit within the MAP signals when the last operand has completed its flow thereby allowing a given process to be interrupted and thereafter restarted. Through the use of read only memory ("ROM") located adjacent the FPGA, a user program may use a single command to select one of several possible pre-loaded algorithms thereby decreasing system reconfiguration time. A computer system memory structure MAP disclosed herein may function in normal or direct memory access ("DMA") modes of operation and, in the latter mode, one device may feed results directly to another thereby allowing pipelining or parallelizing execution of a user defined algorithm. The system of the present invention also provides a user programmable performance monitoring capability and utilizes parallelizer software to automatically detect parallel regions of user applications containing algorithms that can be executed in the programmable hardware.

Abstract: Un procédé permettant de traiter des têtes de poissons comprend les étapes suivantes : on ramollit les têtes de poissons en les chauffant puis on sépare les têtes de poissons en une partie cartilage nasal et en une partie restante au moyen de l'application d'une force de rotation accompagnée d'un choc, et on divise ensuite le cartilage nasal en une partie de bout et une partie postérieure, on coupe la partie de bout en petits morceaux puis on élimine la graisse de ces derniers pour former une pâte et on traite également la partie postérieure pour former une pâte. L'étape consistant à éliminer la graisse de la partie cartilage nasal permet d'obtenir une matière de laquelle on peut extraire le sulfate de chondroïtine et l'étape de traitement de la partie cartilage nasal ou de la partie de bout sous forme de pâte est suivie d'une pulvérisation. A l'aide de ce procédé les têtes de poissons peuvent être facilement et sûrement divisées. De manière plus spécifique, le cartilage nasal prélevé sur les têtes de poissons peut être ensuite divisé à nouveau en partie de bout et en partie postérieure et toutes les parties y compris les parties restantes peuvent être traitées sous forme de produits faciles à utiliser.

Title: Fabrication of gallium nitride semiconductor layers by lateral growth from trench sidewalls
Inventor: LINTHICUM KEVIN J
IPC: C30B25/04
Filed: 1999-06-09
Granted: 2007-01-23
Abstract: A sidewall (105) of an underlying gallium nitride layer (106) is laterally grown into a trench (107) in the underlying gallium nitride layer, to thereby form a lateral gallium nitride semiconductor layer ( 108a).  Microelectronic devices may then be formed in the lateral gallium nitride layer. Dislocation defects do not significantly propagate laterally from the sidewall into the trench in the underlying gallium nitride layer, so that the lateral gallium nitride semiconductor layer is relatively defect free. Moreover, the sidewall growth may be accomplished without the need to mask portions of the underlying gallium nitride layer during growth of the lateral gallium nitride layer. The defect density of the lateral gallium nitride semiconductor layer may be further decreased by growing a second gallium nitride semiconductor layer from the lateral gallium nitride layer.
