Patent CA-2062452-A1 (CA)
Inventor: EL-SHARKAWI MOHAMED A
IPC: H02J3/18
Filed: 1992-03-05
Abstract: A system and method for determining and providing reactive power compensation for an inductive load. A reactive power compensator (50, 50') monitors the voltage and current flowing through each of three distribution lines (52a, 52b, 52c), which are supplying three-phase power to one or more inductive loads. Using signals indicative of the current on each of these lines when the voltage waveform on the line crosses zero, the reactive power compensator determines a reactive power compensation capacitance that must be connected to the lines to maintain a desired VAR level, power factor, or line voltage. Alternatively, an operator can manually select a specific capacitance for connection to each line, or the capacitance can be selected based on a time schedule. The reactive power compensator produces control signals, which are coupled through optical fibers (102/106) to a switch driver (110, 110') to select specific compensation capacitors (112) for connections to each line. The switch driver develops triggering signals that are supplied to a plurality of series-connected solid state switches (350), which control charge current in one direction in respect to ground for each compensation capacitor.

Filed: 1992-09-14
Abstract: ?  5177 ABSTRACT OF THE DISCLOSURE   A method and apparatus for measuring lignin concentration in a  sample of wood pulp or black liquor comprises a light emitting arrangement for emitting an excitation light through optical fiber bundles into a probe which has a sensing end facing the sample.  The excitation light causes the lignin concentration to produce fluorescent emission light which is then conveyed through the probe to analyzing equipment which measures the intensity of the emission light.  Measures are taken to maximize the emission light intensity which is due to lignin concentration and distinguish it from background and interfering light.  The fluorescent light intensity is found to drop off in a predictable manner with increased lignin concentration.

Abstract: Pour noter les écrits se rapportant au contenu de nos vidéocassettes, ce qu'on nous offre présentement sur le marche, ce sont des collants qu'on retrouve à même l'emballage de vidéocassettes. L'usager qui enregistre à plusieurs reprises sur une vidéocassette, doit par le fait même, changer régulièrement ce qu'il y a d'inscrit sur ses collants. Pour remplacer une information écrite par une autre, il y a deux façons de le faire. Premièrement, on peut effacer l'information désuète puis inscrire la nouvelle au même endroit (soit l'effacer avec une efface ou du liquide correcteur). Mais en agissant ainsi la surface du collant devient rapidement malpropre. Deuxièmement, on peut raturer l'information désuète pour inscrire la nouvelle ailleurs. Dans ce cas-ci, l'inconvénient c'est qu'il y a peu d'espace sur un collant pour inscrire de nombreuses données. La présente invention élimine le besoin de raturer, d'effacer l'information désuète, tout en gardant les écrits (les informations se rapportant au contenu de vidéocassettes) dans leur ordre d'apparition sur la cassette. L'invention est un support qui se fixe au boîtier d'une vidéocassette, où l'on peut insérer et retirer des rectangles en papier (c'est sur chacun des rectangles que l'on inscrit l'information se rapportant au contenu de notre vidéocassette). Au lieu de raturer, d'effacer l'information, on remplace un bout de papier par un autre. On conserve l'ordre d'enregistrement, puisque la nouvelle information s'insère dans la même case que l'ancienne, elle conserve, par le fait même, le même rang.

Title: Multilevel coding using trellis-coded modulation and reed-solomon codes
Inventor: WEI LEE-FANG
IPC: G06F11/10
Filed: 1993-02-23
Abstract: A multilevel coded modulation scheme trellis encodes a portion of the input data, and the resulting encoded stream is used to identify a particular one of a predetermined number of subsets of symbols of a predetermined signal constellation. The remaining input data is coded using a Reed-Solomon (RS) code whose output is used to select for transmission a particular symbol from the identified subset. In applications in which phase hits or other channel phenomena may cause the received signal points to be phase-rotated versions of the signal points that were transmitted, differential encoding is included in the overall coded modulation scheme. In different embodiments, the differential encoding/decoding and RS encoding/decoding are in different orders. In one such embodiment, overlapped multilevel codes are used to preserve the advantages afforded by taking a multilevel coding approach.
