Patent CA-2268760-C (CA)
Title: Adaptation resource module and operating method therefor
Inventor: STACEY DAVID JOHN
IPC: H04L49/111
Filed: 1999-04-07
Granted: 2008-06-17
Abstract: In order to support both signalling processing on a per channel basis and multiple adaptation protocols, an interface (10) is modularised principally by function. Incident channels (60-62, Ch0-Ch n) are applied to a routing device (16) that consults a connection map (64) to determine an appropriate path, via an interface (90), for signal processing of each channel, as shown in FIG. 2. Modularised processing platforms (70-74) each contain a number of signal processors (80-86), with each processing platform providing an additional level of indirection with respect to channel handling. In this latter respect, one of the signal processors (86) on each platform is assigned to distribute channel processing to appropriately configured other ones of the signal processors and such that signal processing functions may be distributed between the other ones (80-84) of the signal processors. The present invention is particularly useful in relation to a narrowband-broadband interface to support differing adaptation protocols that require different signal processing functions and also to vary signal processing capabilities on a per call basis.

Title: Support a pictogramme integre
Inventor: BERUBE CLAUDE
IPC: G09F15/00
Filed: 1999-12-02
Granted: 2000-06-27
Abstract: Les supports à pictogramme utilisés actuellement sont inadéquats car, de construction rudimentaire, ils sont difficiles à manipuler par temps froid avec des mitaines. De plus, ils sont en pièces détachées, ce qui augmente l'espace requis pour l'entreposage et le nombre d'étapes d'installation (installation du support-recherche du pictogramme approprié-installation dudit pictogramme sur ledit support). Enfin, les composantes desdits appareils actuels rouillent au contact du sel et calcium ce qui rend la tâche encore plus difficile à l'utilisateur. La présente invention remédie à tous ces inconvénients en reliant les composantes ensemble pour faire un appareil mono-pièce, par l'utilisation de mécanismes plus simples, en utilisant des composantes anti-corrosives et en identifiant le genre de pictogramme incorporé dans l'appareil sur celui-ci.

Title: Appareil et procede de realisation de diamant par nucleation et depot de diamant a l'aide de plasma courant continu a filament chaud
Inventor: SUN BIWU
IPC: H01J37/32
Filed: 1998-07-07
Granted: 2007-05-22
Abstract: La présente invention concerne un procédé et un appareil pour nucléation et croissance de diamant par dépôt de plasma courant continu à filament chaud. L'appareil utilise un ensemble de filaments chauffés par une résistante de façon à dissocier l'hydrogène dans le gaz réactif. Pour la croissance d'un diamant bilatéral, on utilise des configurations substrat - filament chaud - grille - filament chaud - substrat ou substrat - filament chaud - filament chaud -substrat. Dans cette dernière configuration, deux réseaux de filaments indépendants, d'une part servent de filament chaud et de grille,et d'autre part un plasma courant continu est entretenu entre les réseaux de filaments. Pour l'une ou l'autre des configurations d'électrode, l'électrode grille positivement est polarisée par rapport aux filaments chauds pour entretenir un plasma. Le gradient potentiel de plasma entre la grille et le filament chaud attire des ions du plasma vers les filaments. Pour augmenter encore plus les vitesses de dépôt, le réseau de filaments est négativement polarisé par rapport au porte substrat de sorte qu'un plasma courant continu est également entretenu entre le substrat et le réseau de filaments. Pendant la nucléation, le filament adjacent au porte substrat est positivement polarisé par rapport au substrat de manière à accélérer les ions vers le substrat. Il en résulte une amélioration du flux de précurseurs de croissance vers le substrat, ce qui produit une densité élevée de nucléation de diamant sans qu'il y ait besoin d'un traitement préalable de grattage ou d'ensemencement de diamant. Ce procédé de nucléation simplifie le processus de croissance et constitue une façon commode et économique pour une croissance hétéroépitaxiale de nucléi de diamant sur des substrats monocristallins tels qu'un silicium (100).

Granted: 2003-07-15
Abstract: The invention concerns novel varistors based on zinc oxide and a method for making same, which consists in using as base products nanocrystalline powders obtained by high-intensity mechanical grinding and in subjecting the mixture resulting from said nanocrystalline powders a consolidating treatment such as sintering, in suitably selected temperature and time conditions so as to retain the smallest possible grain size of ZnO. The resulting varistors have a very fine homogeneous microstructure and an average grain size characteristically not more than 3 µm, i.e. five times smaller than standard materials. Said novel varistors have a larger number of grain boundaries per length unit and therefore a much higher breakdown voltage. Said voltage is characteristically higher than 10 kV/cm and can reach 17 kV/cm which is almost one order of magnitude above the breakdown voltage of standard varistors. The non-linearity coefficient of the current-voltage curve is also improved, and is greater than 20 and can reach values as high as 60. Moreover, the leakage currents below the breakdown voltage of said varistors, are much weaker.

Abstract: A sample of a hydrocarbon oil containing asphaltenes is chromatographically analyzed by forming a mixture of the oil with a weak solvent. The mixture is passed in contact with a column of a stationary phase of fine solid particles of fully functionalized material, followed by a weak solvent. The solvent, after recovery from the column, is analyzed for aromatics by UV-absorption of UV radiation in the range 200 to 400 nm. The absorbance of the UV light by the irradiated eluents across the UV wavelength range is monitored and the integral of absorbance is derived as a function of photon energy across the wavelength range. The magnitude of the derived integral in at least one time interval corresponding with aromatics in the eluent from the stationary phase is measured as an indication of the level of aromatics in the oil sample.      The weak solvent may ba followed by a strong solvent which, in turn, may be followed by a strong solvent which is modified by the addition of a hydrogen bonding solvent. The solvents are analyzed for saturates, aromatic, polar compounds and any asphaltenic materials by the combination of the UV-absorption measurement and a mass sensitive measurement which measures the combined level of the saturates, aromatics, polars and any asphaltenic compounds present. Equipment to perform the foregoing analysis is also described. The analysis can be used for evaluation of an oil and/or for on-line regulation of an oil refining process.

Abstract: A pool of resource units is configured using a structure having plural levels including first level and second level resource blocks. Each first level resource block corresponds to an individual resource unit, where an individual resource unit is the smallest resource that can be allocated from the resource pool. The first level resource blocks are provided in groups. Each second level resource block corresponds to one of the groups of the first level resource blocks. The second level resource blocks are also provided in groups forming a next higher level of the resource pool. If a request is made for a first level resource block, an available first level resource block is allocated. If a first level resource block is not available, then an available first level resource block is created by converting a second level resource block into a corresponding group of first level resource blocks. One of the converted first level resource blocks is then allocated to the request. Resource blocks are restored to the resource unit pool structure first to any incomplete first level resource block grouping. If that returned block completes the grouping, a new second level resource block is made available. The resource pool may be reconfigured as needed to ensure an efficient configuration.  First and second pools of resource units are configured using a structure having plural levels including first and second level resource units. A relationship is established between one of the two pools of resource units. A request is made for a resource that requires a resource unit from both of the first and second resource unit pools. A single allocation procedure is employed to allocate resource units from both pools. If one of the resource units is available in one pool, the relationship ensures that the required corresponding resource unit in another pool is also available.
