Patent CA-2394736-A1 (CA)
Inventor: CHEN LONG-HSIUNG
IPC: A61B5/15
Filed: 2002-07-23
Abstract: The invention provides a safety syringe for extracting blood, with retractable or removable needle that can be retracted into the syringe body or removed after use and safety locks that lock the retractable needle in an extended position during use and in a retracted position after use to ensure that the syringe is not reused or that the needle is not inadvertently extended. When retracted, the needle assembly is cocked at an angle identifying the syringe as used and adding further protection to prevent the needle from being inadvertently extended and exposed from the tube. These safety features work in conjunction to enhance the usability and increase the safety of the syringe. Thereby protecting medical workers from being injured by an exposed needle or contaminated by disease or infection from contact with the patient's blood present on a used needle.

Abstract: Cette invention se rapporte à un procédé permettant de transmettre sélectivement des ions en utilisant un dispositif FAIMS. A cet effet une première région d'analyse est définie par un espace compris entre une première et une seconde électrode distantes. Une seconde région d'analyse est prévue en communication opérationnelle avec la première région d'analyse. Des ions sont introduits dans la première région d'analyse. Ces ions sont couplés entre la première région d'analyse et la seconde région d'analyse. Une forme d'onde asymétrique est utilisée pour générer un champ électrique dans la première région d'analyse et une tension de compensation est appliquée pour empêcher certains des ions de sortir de la région d'analyse. On réunit dans la seconde région d'analyse les conditions propres à y déclencher une seconde séparation d'ions différente. Finalement, les ions ainsi séparés sont piégés pour qu'ils s'accumulent dans une région de piégeage.

Title: Monitoring system and method for networked data processing installations
Inventor: ROWDEN NEVILLE
IPC: B61L27/00
Filed: 2000-12-30
Abstract: The invention relates to a monitoring system of networked data processing installations (A, B, C, D, E) which has tasks to accomplish relating to security, in particular in the railway engineering field. Said system accomplishes said monitoring task in the form of a subprocess of all the data processing installations (A, B, C, D, E). To this end, each data processing installation takes over tasks during the monitoring of the other data processing installations (A, B, C, D, E). Significant conclusions can be drawn relating to individual data processing installations and to the local and global processes and the data of said individual data processing installations (A, B, C, D, E), based on status data (ZA, ZB, ZC, ZD, ZE), which provides information about local and global processes and the data of the individual data processing installations. The status data results from periodic self-tests (UA, UB, UC, UD, UE) carried out by the data processing installations (A, B, C, D, E) and is output on the network in a visible manner, for all the data processing installations (A, B, C, D, E). The data processing installation which is responsible for carrying out the monitoring can thus, as a result of its own, or of the indirect monitoring of the other data processing installations, identify errors in the data processing installation to be monitored and can initiate corrective measures.
Patent CA-2416368-A1 (CA)
Inventor: MALKEMUS TIMOTHY RAY
IPC: G06F17/30
Filed: 2003-01-16
Abstract: Database Management Systems (DBMS) manage data stored in tables and process database queries against that stored data. The database queries typically specify search conditions (that is, 'predicates') for qualifying database search results to be output by the DBMS. When a database table definition or query includes a given predicate having an expression that operates on a column of a table, it is useful to know whether the expression is monotonic. If the expression is determined to be monotonic, the present invention provides operations for deriving a new predicate from the given predicate for use in a new database query.  Advantageously, the use of a new or derived predicate improves operational efficiency of the DBMS.  Operation is provided for detecting a type of monotonicity related to the expression, and uses the detected type of monotonicity for generating the derived predicate.

Abstract: The present invention relates to silicone-based dental compositions based on a functionalized silicone crosslinkable and/or polymerizable by heat-process. These novel dental compositions are polymerizable and/or crosslinkable in an oral environment, have markedly improved qualities, in particular as regards the very marked reduction in the phenomenon of shrinkage of the materials and prostheses obtained from said compositions. These novel dental compositions are particularly advantageous in terms of reactivity; they are crosslinkable and/or polymerizable by heat, which makes it possible to use conventional crosslinking/polymerization methods and furthermore at temperatures of less than 150° C. This reactivity is in particular due to the presence of a particular type of initiator based on a boron derivative; That initiator is active in low concentration and advantageously requires only small quantities of energy to carry out the crosslinkage/polymerization.
