Patent CA-2194420-A1 (CA)
Title: Global rate control for model-assisted coding of low bit rate video
Inventor: HARTUNG JOHN
IPC: H04N7/50
Filed: 1997-01-06
Abstract: A method and apparatus for coding an image comprising (at least) two regions (e.g., a facial region and a background region) which are to be coded with different quantization error parameters (e.g., quantizer step sizes), wherein the respective quantization error parameters are determined with use of a feed-forward rate control technique. Initial quantization error parameters are assigned to each region, and the overall bit rate which would result for the coding of the given frame is computed based on these assigned quantization error parameters. The computed bit rate is compared to a given bit rate constraint which may, for example, represent a limitation of a transmission channel. Based on the result of this comparison, one or both of the assigned quantization error parameters are adjusted, thereby resulting in different quantization error parameters for the two regions. For example, if the computed bit rate exceeds the given bit rate constraint, at least one of the quantization error parameters is advantageously adjusted in a direction which results in the use of fewer coding bits (e.g., a coarser quantization). If the given bit rate constraint exceeds the computed bit rate, at least one of the quantization error parameters is advantageously adjusted in a direction which results in the use of more coding bits (e.g., a finer quantization resulting in a higher coding quality). Finally, each of the regions is coded based on the correspondingly assigned quantization errorparameters.

Patent CA-2197371-A1 (CA)
Title: Electrical connector
Inventor: PACINI LOUIS S
IPC: H01R13/52
Filed: 1997-02-12
Abstract: An electrical connector may include a housing, a contact, a secondary lock, a grommet, a backplate, a bolt, a contact removal tool, and a splash guard. The housing includes openings for the contacts. The grommets are positioned in the housing, and are subjected to compressive forces to provide a seal. As the contact is inserted, a locking tab engages the contact and prevents it from being removed. The secondary locks increase the retention contact, and permits the partial insertion and retention of the secondary lock prior to insertion of the contact. The secondary lock also assures proper contact insertion. The splash guard assists in deflecting water from the rear of the connector. The removal tool may be used to remove contacts from the electrical connector, and can be stored in the connector.
Patent CA-2200984-A1 (CA)
Inventor: LANGER ROBERT S
IPC: A61N1/32
Filed: 1996-07-25
Abstract: Plusieurs moyens permettant d'améliorer le transport transdermique de médicaments et de substances à analyser ont été mis au point, à savoir l'utilisation d'ultrasons basse fréquence, de modificateurs chimiques de la perméabilité et/ou de la cavitation, l'iontophorèse et/ou l'électroporation (champs électriques), la pression et/ou le vide (moyens physiques) et des champs magnétiques. La production d'ultrasons basse fréquence (de 20 KHz à 1 MHz environ) améliore le transport transdermique de médicaments et la mesure de la concentration de substances à analyser dans les liquides organiques tels que le sang ou la lymphe. Ce transport peut être encore amélioré ou mieux régulé par l'emploi de véhicules pour les médicaments, tels que les liposomes ou les microparticules, si l'on fait appel à une vaste plage d'intensités et de fréquences dans les ultrasons. Les microparticules sont de préférence de petite taille. On peut rendre leur surface plus hydrophile ou plus lipophile, ce qui en améliorera encore le transport.

Patent CA-2206935-A1 (CA)
Title: Process for production of radiostrontium
Inventor: VINCENT JOHN
IPC: C01F11/00
Filed: 1997-06-03
Abstract: A process for the production of radiostrontium consists  in  that  a  target  of  metallic  rubidium  is bombarded by a flow of accelerating charged particles. The target of irradiated rubidium is melted, whereas the extraction of radiostrontium is carried out by sorption on the surface of a sorbing material immersed into the irradiated  molten  metallic  rubidium.  As  the  sorbing material,  use  is made  of materials  selected  from the group  consisting  of  heat-resistant  metals  or  metallic oxides  or  silicon  which  are  inert  with  respect  to rubidium. The resultant radiostrontium is extracted from the irradiated rubidium. The temperature of the sorbing material is selected to be close to the optimum one for the sorption of radiostrontium which is within the range of from the melting point of metallic rubidium to 220°C. And the temperature of molten rubidium is selected to be close  to  the  optimum  one  for  the  desorption  of radiostrontium within the range of from 220°C to 270°C.

Patent CA-2207643-A1 (CA)
Title: Lithium ion electrochemical cell with safety valve electrical disconnect
Inventor: NAING HTUN STANLEY
IPC: H01M50/574
Filed: 1997-06-12
Abstract: An explosion-proof valve electrical disconnect assembly incorporates a vent valve contact disk which seals the can of a compact electrochemical cell and which faces a juxtaposed stripper contact disk welded at the center by a weld nugget at a weld point, forming a rigid, preferably increased thickness, mass. The underlying stripper contact disk is weakened about the weld point, surrounding the weld nugget to ensure pull-through of the stripper contact disk portion immediately adjacent to the weld connection to effect initial  electrical  separation of  the  two  contact disks.  Subsequent rupture of the vent valve contact disk releases high pressure gas internally from the cell.  A semi-rigid assembly cup may support a rigid grommet functioning to sandwich the vent valve contact disk and the stripper contact disk facilitated by crimping of the can top about a deformable L-shaped cross-section  annular  assembly  cup.    A  current responsive PTC element forms a second circuit breaker independent of the first mechanical circuit breaker formed by the two contact disks.

Title: Error-correcting code generating circuit and modulator apparatus using the same
Inventor: HIRAMATSU KATSUHIKO
IPC: H03M13/00
Filed: 1997-07-14
Abstract: An error-correcting code generating circuit includes a shift register incarnating a generating polynomial, an exclusive logical sum means, and a logical circuit means for performing arithmetic operations on N bits (where N represents an integer not smaller than two) held by said shift register at one time with a clock having a frequency corresponding to 1/N on the basis of N bits (where N represents an integer not smaller than two) inputted in parallel, to thereby generate an error-correcting code of N bits with a single-shot of clock. Because the error correcting code can be generated through the parallel processing, operation can be executed at a low speed with power consumption as involved being reduced.

IPC: B02C15/06
Filed: 1996-05-29
Abstract: Cette invention concerne un broyeur à cylindres annelés fonctionnant à vitesse sous-critique et comportant au moins un anneau de broyage à l'intérieur duquel est encastré au moins un cylindre.  On peut faire usage d'un tel broyeur, lorsqu'on produit du ciment, pour broyer des matériaux minéraux de mâchefer, du laitier et d'autres matériaux analogues.  Cette invention permet d'obtenir un broyeur à cylindres annelés qui ne produit pas de vibrations indésirables et ne se désaligne pas en cours d'utilisation, ce qui est rendu possible en disposant dans le broyeur des accessoires internes en forme d'unités d'impact et de distribution.  Ces unités sont placés sur la trajectoire suivie par le compactat lorsqu'il tombe de l'anneau et s'achemine dans sa descente vers la zone d'entrée.  Au cours du processus de broyage, les unités d'impact et de distribution désagrègent les agglomérats, s'il en existe, tout en répartissant le matériau désagrégé sur une couche uniforme sous le niveau de la zone d'entrée.  On obtient l'impact le plus fort lorsque le matériau entre en contact avec l'unité suivant un angle de 60 à 110 degrés.
