Patent CA-2385342-A1 (CA)
Title: Improved electrochemical sensor
Inventor: DENG YINGPING
IPC: G01N27/327
Filed: 2002-05-08
Abstract: Disclosed is an improved electrochemical sensor for the detection of an analyte in a fluid test sample. The electro-chemical sensor is of the type in which the fluid test sample is drawn into a capillary space and the improvement to the sensor involves an arrangement where a portion of the sensor's counter electrode is placed on the edge of the capillary space in a relationship to the sensor's working electrode such that if the capillary space is not completely filled there will be generated only a very weak current. When the sensor is con-nected to a properly programmed current detector, the weak current caused by the underfilling of the capillary space will be detected as an error and will notify the user of the sensor that the test should not be continued.

Abstract: The invention relates to a method for producing biologically active ingredients. Active ingredients comprising additional functional groups, a modified spectrum of activity and modified application properties can be obtained from medicaments or plant protection agents in the form of substrat es which, as functional groups, carry at least one amino or hydroxyl group. Sai d active ingredients can be obtained by means of a one-electron reaction which  is catalysed using enzymes or mixtures exhibiting enzymatic activity with a broad substrate spectrum. The method is characterised in that radical-formin g enzymes are used as enzymes, and/or supernatants of ligninolytic mushrooms i n an aqueous solution are used as mixtures exhibiting enzymatic activity. The following can be introduced in the form of additional functional groups: A) polyfunctional synthones which give the active ingredient a different soluti on behaviour in aqueous and lipophile systems, and high interfacial activity, B ) aromatic molecules and heteroaromatic compounds, C) heterocyclic compounds, D) active ingredients with independent biological efficacy, and E) active ingredients which bring together independent activity and surfactant properties in one molecule. Together, said additional functional groups and the starting products produce covalently linked coupling products exhibiting  modified distribution behaviour, by means of which polyfunctional interactio n with the target organism is made possible.

Title: Method and apparatus for transmitting nrz data signals across an isolation barrier disposed in an interface between adjacent devices on a bus
Inventor: OPRESCU FLORIN
IPC: G06F13/40
Filed: 1993-12-16
Abstract: The present invention provides a method and apparatus for transmitting NRZ data signals across an interface comprising an isolation barrier disposed between two devices interconnected via a bus. The apparatus comprises a signal differentiator for receiving an NRZ data signal and outputting a differentiated signal. A driver comprising a tristate gate has as a first input the data signal and as a second input the differentiated signal for enabling the tri-state gate when the differentiated signal is high. A bias voltage is applied to an output of the tri-state gate to derive as output a transmission signal for transmission via the bus across the interface between the two devices. In this way, the transmission signal output from the first device comprises an intermediate transmission signal corresponding to the bias voltage when the tri-state gate is disabled, a high transmission signal when the tri-state gate is enabled and the first input to the tri-state gate is high, and a low transmission signal when the tri-state gate is enabled and the first input to the tri-state gate is low. A Schmidt trigger is provided as a receiver in the second device for receiving as input the transmission signal and outputting a reconstituted data signal corresponding to the synchronized data signal.

Patent CA-2418163-A1 (CA)
Inventor: LIU LINQI
IPC: G06F17/30
Filed: 2003-01-31
Abstract: A method of query transformation using window aggregation to transform queri es involving subqueries. An optimizer in a relational database management system transfor ms queries to optimize their efficiency and speed. The method transforms queries that have a subquery, replacing the subquery with a window aggregation function. In the case of a correlated subquery, the window aggregation function is partitioned by a correlated column of a correlated table. All data in the main select, or outer block, of the query that was obtained through references to the correlated table is instead obtained through the new window aggregation subquery. By using windo w aggregation, the aggregation is performed at the same time as the selection of relevant data from the correlated table, thereby compiling all needed data in a single pass through the table or view . Reducing the number of times that tables or views are accessed reduces the computational demands of a query.
