Patent CA-2308807-A1 (CA)
Inventor: SUN DE-GUI
IPC: G02F1/01
Filed: 2000-05-12
Abstract: An optical waveguide switch using two unidirectional waveguide couplers with coupling gratings is provided. Each unidirectional waveguide coupler compromises two waveguide channels and a coupling grating along one waveguide channel. Two such waveguide couplers with coupling gratings are positioned on a substrate to form a symmetric couple-pair.      An optical signal launched into the input port of the first coupler may exit from the output port of the second coupler. A modulating electrode is used to eliminate the coupling gratings on the two couplers, and the optical signal launched into the input port of the first coupler exits from its own output port. Similarily, this process can also be performed for an optical signal launched into the second coupler. Thus an effective 2x2 switching performance is implemented with this structure. MxN switching performance may also be implemented with several 2x2 waveguide switches.

Patent CA-2320892-A1 (CA)
Inventor: ANDO YASUOMI
IPC: H04L5/02
Filed: 1999-12-17
Abstract: Out of devices connected to the same power line (7), a device which has judged based on the results of noise measurement that it is difficult to continue communication in the case of the current tone-set/tone position comes to serve as a virtual master for tone change. The device serving as a virtual master transmits a tone change request command and waits for a response from another device for a predetermined time. If the virtual master device receives even one tone change rejection command during the time, the virtual master device abandons the change and ends the virtual master processing. Conversely, if the virtual master device receives no tone change rejection command in the predetermined time, the virtual master device transmits a tone change instruction command. On receiving the tone change instruction command, all the other devices currently connected change the tone at a time.

Abstract: On décrit un procédé et un dispositif permettant d'effectuer le coulage de métal en mode continu ou semi-continu dans lesquels de la fonte chaude est envoyée dans un moule de coulage en continu refroidi, la fonte étant refroidie et formée sous forme d'une barre au moins partiellement solidifiée lorsqu'elle traverse le moule. Une bobine d'induction est placée à l'extrémité supérieure du moule pour générer, lorsqu'elle reçoit un courant électrique alternatif haute fréquence, un champ magnétique haute fréquence qui agit sur la fonte située dans le moule, ceci ayant pour effet de produire de la chaleur dans la fonte et de créer des forces de compression qui servent à séparer la fonte de la paroi du moule. La bobine est alimentée en courant haute fréquence par une unité d'alimentation en puissance comprenant un système de régulation du courant qui permet de fournir à la bobine d'induction un courant électrique alternatif haute fréquence ayant une fréquence de base supérieure ou égale à 50 Hz. Le système de régulation du courant comprend un dispositif de modulation qui permet de moduler et de réguler le courant fourni de manière pulsée et modulée en amplitude avec une fréquence de modulation d'amplitude inférieure ou égale à 10 Hz, de sorte qu'essentiellement l'amplitude totale du courant modulé en amplitude est obtenue dans un temps de montée correspondant à 1 cycle de la fréquence de base ou moins au début d'une impulsion.

Title: Method and apparatus for providing rate control in a video encoder
Inventor: WU SIU-WAI
IPC: H04N7/26
Filed: 1999-09-29
Abstract: A method and apparatus are provided for controlling the quantization level in a digital video encoder that comprises a plurality of parallel compression engines (12). The input picture is partitioned into a number of panels (10) and each panel is processed by a distinct compression engine (12). A reference quantizer scale is determined before encoding a frame of video. The reference quantizer scale is used at the first slice of every video image panel being processed by the video encoder. The quantizer scale at the last slice of the image panel is then forced to be the same as the first slice. The forcing step can use a piecewise-linear feedback formula. A group of pictures (GOP) target bit rate is adjusted based on the number of film pictures and non-film pictures currently in the processing pipeline of at least one of the compression engines. A higher target bit rate is provided for non-film pictures. A buffer (16) level of the video encoder is used to control the start of a new group of pictures (GOP). The start of a new GOP is delayed if the buffer (16) does not have sufficient space to accommodate an intra-coded (I) frame for the new GOP.
