Patent CA-2203747-C (CA)
Inventor: MCCOURT ROBERT W
IPC: G01R29/08
Filed: 1997-04-25
Granted: 1999-07-20
Abstract: There is disclosed a methodology for measuring the magnetic field strengths of fundamental and harmonic frequencies associated with a.c. electrical current flows over a protracted period of time; and, particularly , in hostile environments. A preferable application calls for the determination of the field strengths associated with electrical currents flowing in a.c. power, distribution lines of utilities. The monitoring instrument is positioned in relation to the power lines to be monitored, typically at the base of a pole immediately adjacent the pole of the power line or on a power line supporting pole itself. In order to provide for long term, powering of the monitoring device, d.c. power is developed utilizing the a.c. power that is present. The conversion from a.c. to d.c. is effected at a distance sufficiently far from the monitoring instrument so as not to have any consequence on the readings that are being taken. Readings during the protracted period are typically stored and then accessable at pre-determined periods. A procedure for checking operability of the instrument is disclosed. The methodology further includes a technique for determining the lateral profile of magnetic field strengths for transverse distances from the location site of the monitoring instrument. The methodology disclosed has broad application including workplace monitoring.

Title: Sub-pixel dataform reader
Inventor: YE ANQI
IPC: G06K7/10
Filed: 1996-10-10
Granted: 2006-03-07
Abstract: Sub-pixel processing of image data representing a dataform, such as a 2D bar code, enables reading of dataforms including more data/smaller elements, without costly increases in sensor and memory capacity. Whole pixel processing is employed for pixel-per-element resolutions of two or better. Sub-pixel cell edge transition location in image data is enhanced by use of a dynamically implemented noise margin applied with bands of gray scale values (150, 152) designated within the enveloppe of applicable gray scale maximum (119) and minimum (120) values. Sub-pixel cell edge transition location employs selection of transition segments (121-124), subject to the noise margin, and determination of a dynamic threshold (158) for each relevant transition segment (122). The intersection of the threshold (158) and the transition segment ( 122) is then indicative of the location of the cell edge transition along a sampling line crossing the dataform. The process is repeated for successive cell edges along image data sampling lines crossing successive rows of dataform elements. Run length data representing cell edge transition locations is constructed and usable for dataform decoding.

Abstract: A substantial and increasing problem with the pulping chemical recovery system, is the presence of chloride and potassium in the spent liquor entering the recovery boiler. Chloride and potassium increase the stickiness of carryover deposits and dust particles to the recovery boiler tubes, which accelerate fouling and plugging in the upper part of the recovery boiler. The present invention relates to a process by which the content of potassium ions in a recovery system for pulping chemicals can be reduced. The process comprises bringing spent liquor to a recovery boiler, burning said spent liquor, collecting precipitator dust formed, forming a solution by dissolving the precipitator dust in a liquid, where the solution of precipitator dust is subjected to a treatment with an inorganic ion exchange material in order to remove at least a part of the potassium therein.

Title: Method and apparatus for the management of medical files
Inventor: BESSETTE LUC
IPC: G06F19/00
Filed: 1998-04-01
Granted: 2001-02-06
Abstract: The present invention provides a network system for storage of medical records. The records are stored on a server in a database. Each record includes two parts, namely a collection of data elements containing information of medical nature for the certain individual, and a plurality of pointers providing addresses or remote locations where reside other medical data for that particular individual. Each record also includes a data element indicative of the basic type of the medical data found at the location pointed to by the pointer. This arrangement permits a client workstation to download the record along with the set of pointers toward the remotely stored files. The identification of the basic type of information that each pointer leads to allows the physician to select the ones of interest and thus avoid downloading massive amounts of data where only part of that data is needed at that time. In addition, this record structure allows statistical queries to be effected without the necessity of accessing the data behind the pointers. For instance, a query can be build based on keys one of which is the type of data that a pointer may lead to. The query can thus be performed solely on the basis of they pointers and the remaining information held in the record.

Granted: 2000-09-19
Abstract: L'invention concerne un procédé permettant d'atténuer les réverbérations dans les données d'un câble de fond d'océan utilisées pour générer un profil sismique. On commence par générer une onde sismique, qui est enregistrée par des paires de capteurs de pression et de vitesse de propagation des particules. On ajoute le produit des données de pression multipliées par la valeur absolue des données de vitesse de propagation au produit des données de vitesse de propagation multipliées par la valeur absolue des données de pression, ce qui élimine les réverbérations et donne un signal combiné fonction uniquement du signal de réponse de l'onde primaire. On divise le signal combiné par 2 et par un facteur d'échelle de la sensibilité, puis on prend la racine carrée du résultat, ce qui donne la grandeur du signal primaire. On remplace le signe positif/négatif du signal combiné qui existait avant que l'on prenne la valeur absolue, ce qui donne la bonne polarité. Les données sont ensuite incorporées en un profil sismique.

Abstract: A method and an apparatus for improving agent efficiency by reducing non-productive time such as time on hold and time for wrap-up statements. After an agent has been connected to a call the agent may determine that automated handling of the call is appropriate. Depending upon the status of the call the agent may specify that the call has been essentially completed or that the agent is on hold. The agent may speak the name of the connected party and this will be recorded. Then the agent is disconnected from the call and a message playing device, which may also replay the spoken name, is activated. If the response from the connected party indicates that an agent's attention is again needed then the same or a different agent is connected to the call. In addition, a party on hold is provided an estimate of the time before an agent becomes available and/or the number of parties ahead in the holding queue.
