Title: Procede et dispositif de mesure de la densite
Inventor: ULLBERG ANDERS
IPC: G01N33/46
Filed: 1997-03-20
Abstract: L'invention porte sur un dispositif de mesure de la densité ou de détection de la présence et de la quantité de matériaux de densités différentes dans un objet (9, 18) à évaluer qu'il s'agisse de liquides, de solides ou de gaz. Ledit dispositif comporte au moins une source (5, 12) de rayonnement électromagnétique, et au moins un détecteur (6, 13) de mesure de l'intensité du rayonnement, placé de manière à absorber le rayonnement de la source (5, 12) et relié à une unité de calcul (8, 16). Selon l'invention, le dispositif émet des rayons de deux longueurs d'ondes et comprend des moyens de mesure permettant de déterminer l'étendue de l'objet (9, 18) entre la source (5, 12) et le détecteur (6, 13). En outre, l'invention porte sur un procédé de mesure de la densité consistant à irradier par des rayons électromagnétiques un objet (9, 18) à évaluer, puis à mesurer l'intensité du rayonnement du côté où les rayons sortent de l'objet (9, 18). Selon le procédé, on mesure l'étendue de l'objet (9, 18) le long de la trajectoire des rayons à travers l'objet à mesurer, le rayonnement étant émis au moins sur deux longueurs d'ondes distinctes.
Patent CA-2252106-A1 (CA)
Inventor: YUE KELVIN K
IPC: G06F9/46
Filed: 1998-10-28
Abstract: A method and apparatus for implementing proportional sharing in a single processor system and/or in a multi-processor system. The invention can also implement proportional sharing in a system that executes multi-threaded computer programs. The invention uses the metaphor of "tickets." Each process in the system has a number of tickets and each ticket entitles the process to use a processor for a period of a time quantum. The operating system allocates the processor(s) first to the process with the highest number of tickets. As each process (or thread) finishes being executed for a predetermined amount of time, the tickets of that process/thread are adjusted accordingly and a new process (or thread) is chosen for execution. Tickets can be allocated to each process in thesystem. Alternatively, tickets can be allocated to each process and shared by all threads of the process. Alternatively, tickets can be allocated to a group of processes and shared by all processes within the group.

Title: Functionalization of hydrocarbyl-containing compounds
Inventor: COOK GERALD KENNETH
IPC: C07C29/09
Filed: 1997-07-03
Abstract: This invention is directed to processes for producing acyclic or cyclic alcohols or glycols, carbonyls, oxiranes or aziridines from hydrocarbyl group-containing compounds, particularly lower alkanes such as methane, ethane, propane or butanes, in which the hydrocarbyl group-containing compounds are converted under regioselective conditions to a functionalized ultimate precursor from which the final products can be produced.

Title: Location-dependent call forwarding
Inventor: ALPEROVICH VLADIMIR
IPC: H04Q3/00
Filed: 1997-11-18
Abstract: An improved cellular communications system and method is disclosed which routes incoming calls to those subscribers who do not answer their page. The incoming call is routed to one of a list of alternate numbers, such as a home or work number in a public telephone system. Based upon the last known location of the subscriber within the cellular system, a particular list of such alternate numbers are tried in an effort to contact the subscriber outside the cellular network. Different lists are utilized depending upon the subscriber's last known location. In a first embodiment of the present invention, the various lists are stored in a home location register (26) for the cellular system (10) which forwards a particular list to the mobile switching center (14) servicing the subscriber. In a second embodiment of the present invention, the particular list is stored within and forwarded by a service control point (30) within an intelligent network.

Title: Drillpipe structures to accommodate downhole testing
Inventor: WISLER MACMILLAN M
IPC: E21B47/12
Filed: 1999-05-13
Abstract: A drill collar structure to facilitate measurement-while-drilling (MWD) techniques while at the same time having sufficient rigidity to facilitate the drilling operation is disclosed. In some embodiments, a metal structure involving openings such as slots, preferably oriented longitudinally along its axis, but also in other configurations, are disclosed to allow sufficient strength while at the same time allowing exit and entrance of electromagnetic energy.  A composite structure is also disclosed which, for given layers, has adjacent fibers such as glass and carbon, so that when the layers are overlapped, glass areas overlap glass areas throughout the radial thickness of the composite tube to create "windows" for the entrance and exit of electromagnetic energy. In yet other embodiments, the drill collar can be made of a metallic frame structure with a multiplicity of openings which are filled with a composite material. The metallic frame structure provides structural rigidity while the openings, filled with composite material which are attached to the metal structure, form a fluid-tight cohesive structure sufficient to withstand the rigors of drilling, while at the same time allow the measurements of the formation to be taken through the windows or by making use of sensors embedded in the windows. In another alternative composite structure, carbon fibers can be used if they are electrically insulated in the areas where electromagnetic energy is to enter and exit the structure. Another composite alternative is to alternate carbon and glass fibers in particular sequences or to use insulated carbon fibers to facilitate the operation of instruments which can be mounted in the structure whose operation could be negatively affected by conductivity in the wall in an azimuthal direction.

Patent CA-2276634-A1 (CA)
Inventor: AUFRICHTIG RICHARD
IPC: G06T5/20
Filed: 1999-06-25
Abstract: A discrete pixel image is enhanced to bring out particular features of interest such as edges. The enhancement includes decomposition of the original processed image data, enhancement by application of gain images to the decomposed images, and reconstruction of the enhanced image. The decomposition proceeds through a series of low-pass filters to arrive at decomposed images of progressively lower spatial frequencies. These decomposed images are then multiplied by gain images during the enhancement phase. Gain images for at least the higher spatial frequency level images are derived from lower spatial frequency level images. These spatial frequency-based gain images may be based upon operator inputs, including a spatial sensitivity function and an edge enhancement value. Lower spatial frequency level image may be processed by application of predetermined gain values. The reconstruction sequence recombines the decomposed images after application of the gains to arrive at an enhanced image of the same dimensions as the original image.
Patent CA-2277268-A1 (CA)
Inventor: BODIN ROLAND STIG
IPC: H04L29/06
Filed: 1998-01-09
Abstract: A method and system for improving the routing of messages in a radiocommunication system are disclosed. In an exemplary system, messages which originate at a mobile unit are routed through both a service center associated with the originating mobile and a service center associated with a recipient mobile. If the recipient has subscribed to an enhanced message routing service, then the home location register returns an address of the recipient's service center in response to a request for routing information. When the home location register is queried again for routing information for the same message, the enhanced message service indicator is suppressed so that the home location register returns a routing number for the equipment which is currently supporting radiocommunication with the recipient, rather than returning the service center address a second time.
