Patent CA-2124604-C (CA)

Abstract: A method for operating a processor-controlled machine and a machine having a processor are disclosed for operating on an object-based model data structure from which a first image has been produced in order to produce a second image for display in the spatial context of the first image. A viewing operation region (VOR) is displayed coextensively with a first image segment of the first image in the display area of the machine's display device. The first image segment includes a display object representing a model data item in the object-based model data structure. In response to the display of the VOR, a second image is produced using the model data item in the object-based model data structure. The second image is displayed in the VOR, in the spatial context of the first image, simultaneously with the display of the first image, replacing the first image segment in the display area. In one aspect of the invention, the display object in the first image includes a display feature, and the second image presented in the VOR, in the spatial context of the first image, shows the display object having a modified display feature. In one illustrated implementation, the method operates cooperatively with a graphical object editor application executing in a graphical user interface environment. A machine user moves the VOR over a portion of a graphical object image, and in response to the user's movement action, a viewing operation associated with the VOR operates on the editable object-based model data structure that produced the graphical object image to produce a second modified view of the portion of the graphical object image coextensively positioned with the VOR, displaying the second modified view in the VOR. The method also supports object selection, permitting second views to be produced according to the viewing operation for seleded display objects in the first image.

Abstract: Circuit (350) de commande de fréquence et procédé associé (700) destinés à un récepteur fonctionnant de façon à recevoir un signal à accès multiple à répartition dans le temps (AMRT) émis par un émetteur dans un système de communication AMRT. Un premier détecteur (452) de fréquence génère un premier signal (468) de commande de fréquence. Un second détecteur de fréquence, comprenant une partie d'un démodulateur orienté décision (450), génère un second signal (496) de commande de fréquence. Le premier signal (468) est utilisé pour effectuer la commande de fréquence lorsqu'un signal est reçu en continu par le récepteur, par exemple au cours des périodes succédant immédiatement à la mise sous tension initiale du récepteur, lorsque celui-ci se synchronise avec le signal AMRT qui lui est transmis. Une fois qu'il est synchronisé par rapport à l'émetteur, le récepteur ne requiert qu'une alimentation intermittente au cours des intervalles de temps pendant lesquels le signal AMRT est transmis au récepteur. Le second signal (496) de commande de fréquence est utilisé pour effectuer la commande de fréquence uniquement après que le récepteur a été synchronisé par rapport à l'émetteur, afin de permettre le fonctionnement intermittent du récepteur, et lorsque la différence de fréquence entre le signal transmis au récepteur et une fréquence d'oscillation d'un récepteur-oscillateur est inférieure au niveau maximum.

Title: Expansion turbine for cryogenic rectification system
Inventor: NENOV NENO TODOROV
IPC: F01D15/00
Filed: 1995-06-14
Granted: 1999-05-25
Abstract: A turboexpander, particularly suited for use in a cryogenic rectification system, comprises a center housing rotatably supporting an elongated shaft to opposite ends of which are mounted a turbine wheel within a turbine housing and a compressor wheel within a compressor housing or a brake within a load housing. The turbine wheel has circumferentially spaced turbine blades.  Process fluid is introduced so as to flow through annular nozzles or guide vanes which encompass the turbine wheel.  The guide vanes direct the process fluid through the turbine blades and each extends between a leading edge more distant from the turbine wheel and a trailing edge less distant from the turbine wheel.  Each guide vane is substantially uncontoured between its leading edge and the trailing edge and is substantially thicker at the leading edge than at the trailing edge.  A thermal shield thermally isolates the turbine housing and the process fluid within the turbine housing from the central housing and the lubricant within said central housing.  A labyrinth seal construction along the length of the shaft between the bearings and the turbine housing prevents migration of the lubricant along the shaft into the turbine housing and prevents migration of the process fluid out of the turbine housing along the shaft and into the central housing.  Sealing gas may also be provided to the labyrinth seal construction as an additional expedient to prevent migration of the lubricant along the shaft and of the process fluid out of the turbine. Superior performance is achieved by the relative dimensioning of certain components.

Abstract: A fiber optic diffuse light reflectance sensor is disclosed. The sensor employs illumination optical fibers to carry light emitted from a high-intensity, narrow bandwidth LED to a baffle in a readhead where the optical fibers reflect the light off of a reagent test strip. The illumination optical fibers are randomly oriented to create a more uniform light source. The light is reflected off of a pad on a reagent test strip to detect the presence of non-hemolyzed trace and hemolyzed occult blood. The reflected light must pass through another baffle to a bi-convex lens where it is focused onto a detection bundle of optical fibers. The detection bundle is optically coupled with a CCD, where the optical signal is converted to an electrical one for processing and analysis.

Abstract: A method of forming a memory device with improved isolation between diffusion lines. Parallel, spaced apart thick oxide strips (201) are grown on a substrate. Next, spaced apart, parallel strips (302) having a polysilicon (302a) and nitride (302b) layer, oriented perpendicular to the first strips (201), are formed. The oxide (201 ) between the second strips is removed, followed by an implantation to form source (402) and drain (401) regions. The nitride layer (302B) on the second strips is removed on those strips between two drain diffusions (401) and an oxidation is performed to form self-aligned thick oxide (602) over the source and drain regions. The strips from which the nitride has been removed are also oxidized, thus providing isolation between adjacent drain lines.
