Patent CA-2298843-A1 (CA)
Inventor: NAESS SARA K
IPC: C12Q1/6895
Filed: 1998-07-27
Abstract: This invention provides novel germplasm, breeding stock, genetic markers and methods for introducing resistance to late blight and other diseases into cultivated potato plants. The germplasm is derived from a segment of the Solanum bulbocastanum genome that contains one or more genes conferring resistance to late blight. The S. bulbocastanum genome is introduced into cultivated potato by somatic hybridization of S. bulbocastanum with S.  tuberosum. Also provided is a S. bulbocastanum RAPD fragment marker that co-segregates with the disease resistance gene. In addition, chromosome 8 RFLP  markers are provided, which also are tightly linked to the resistance gene(s).  These markers are used to monitor passage of the disease resistance trait in breeding crosses. The markers are also used to facilitate isolation of the S.  bulbocastanum gene or genes responsible for the disease resistance.

Patent CA-2302200-A1 (CA)
Inventor: TABUKI TAKAAKI
IPC: H04L9/32
Filed: 1998-09-01
Abstract: Ce système de signature numérique fonctionne sur un principe de clé publique facilitant la gestion de la clé privée et la rendant plus commode. En l'occurrence, une unité de gestion (16) de clés de cryptage de signatures dynamiques se fait communiquer, d'une part des données enregistrées de signatures dynamiques, et d'autre part une clé privée prise dans une base de données de gestion (12) sur la base d'un identificateur (ID) en provenance d'un utilisateur. Le principe consiste alors à prendre les données enregistrées de signatures dynamiques et les données d'authentification de signatures dynamiques, et à les faire interclasser par une unité d'interclassement (14) de signatures dynamiques. S'il s'avère que ces données sont identiques, l'unité de gestion (16) de clés de cryptage de signatures dynamiques fournit à une unité de calcul de cryptage (18) les données de message envoyées par l'utilisateur ainsi que la clé privée, laquelle unité de calcul de cryptage envoie à l'unité de gestion (16) de clés de cryptage de signatures dynamiques essentiellement les données de message cryptées au moyen de la clé privée. Cette unité de gestion (16) de clés de cryptage de signatures dynamiques renvoie à l'utilisateur notamment les données de message qui sont cryptées, c'est-à-dire signées. Les utilisateurs n'ont ainsi plus à assurer eux-même leurs clés privées, ce qui permet de réaliser un système de signature numérique plutôt commode.
Patent CA-2302542-A1 (CA)
Inventor: BOOTH ROBERT THOMSON
IPC: G01W1/14
Filed: 2000-03-15
Abstract: " This invention relates to improvements in rain gauges that measure the start of a rain event." " An object of the invention is to provide accuracy as well as simplicity in determining the start of rain events after placement of said device. This knowledge is extremely useful in pesticide applications." "In agriculture and horticulture some chemicals require a rain free period of 2- 6 hours, other types of chemicals require rain to occur within a week to be activated. The timer is able to count for 9 days. The Rainfall Timer will inform the applicator the amount of rain that fell relative to field placement. It is often difficult to determine the timing of a rain event, what commonly occurs when doubt exists to a rain event; a respray occurs. This is common in the industry" "Although sophisticated devices exist that inform the start, duration, and stop of rain events their complex design and cost render their use impractical to a pesticide applicator. Many models are capable of transmitting data back to a home base and are prone to loosing data either to electrical disturbances, wind or wildlife. The most important information that a rain event timer yields to a pesticide applicator is the start of a rain event rather than amount, duration, end or amount of precipitation." "To this end once the Rainfall Timer is activated by a predetermined amount of rain, the data is stored safely in the unit baring complete unit destruction." " The simplicity of the Rainfall Timer enables it useful to pesticide applicators who require a simple reliable device to inform them of the start of a rain event to accurately base respray decisions."

Abstract: In a publically switched telephone network (PSTN), a method and a system for simultaneously and independently multiplexing voice and non-voice data over a single, commonly shared PSTN access line. This is accomplished by packetizing the voice and non-voice data into minicells, and then multiplexing the minicells into a single data stream for transportation across the commonly shared PSTN access line. Once the minicells containing either voice or non-voice data have been transported over the single, commonly shared PSTN access line, the data is simultaneously and independently routed to distinctly different end-users according to the routing information stored in the header portion of each minicell.

Title: Method for spectroscopic analysis of hydrocarbons, and hydrocarbon refining operations using same
Inventor: ROBBINS WINSTON KARL
IPC: G01N30/02
Filed: 1990-05-07
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.

Patent CA-2318934-A1 (CA)
Title: Circuit d'attaque de ligne a transitions lineaires
Inventor: GUPTA ATUL
IPC: H04L25/03
Filed: 1999-01-19
Abstract: L'invention concerne un circuit d'attaque de câble émettant un signal de sortie sensiblement linéaire qui correspond à un signal d'entrée reçu par le circuit d'attaque de câble sur une ligne de transmission. Le circuit d'attaque de câble comprend plusieurs commutateurs couplés avec des éléments de temporisation. Cela permet aux commutateurs de fonctionner de manière séquentielle en réaction à un signal de sortie. Chacun des commutateurs relie une source de courant correspondante à un port de sortie; par conséquent, un signal de sortie sensiblement linéaire est émis sur la ligne de transmission connectée au port de sortie. Le fait que le signal de sortie soit pratiquement linéaire augmente la vitesse à laquelle les données peuvent être transmises via la ligne de transmission; en outre, il est possible de commander le temps de montée et de descente d'une partie déterminée du signal de sortie pour assurer l'absence de toute interférence électromagnétique.
