Inventor: KOCHETOV IVAN ALEXANDROVICH
IPC: G01N33/52
Filed: 1995-12-14
Abstract: The invention relates to an analytical kit for determining a level of an analyte on a solid surface, comprising (a) a source of hydrogen peroxide; (b) a source of an affinity-enzymatic compound of formula A-C-B, wherein A is a detecting agent having affinity for the analyte, B is an enzymatic visualizing agent consisting of peroxidase and C is a binding agent linking the detecting agent and the visualizing agent to one another; and (c) a multilayer analytical element comprising a solid support and a hydrophilic layer thereon, the hydrophilic layer being formed of gelatin, polyvinyl alcohol or a mixture thereof and containing a developing agent and a hydrophobic color-producing agent in a total amount of 5 to 30 weight %, the developing agent and the color-producing agent being present in a weight ratio of 1:0.3 to 1:3Ø The developing agent and the color-producing agent co-act with one another in a manner such that, when a predetermined amount of the affinity-enzymatic compound is applied onto the surface in a selected area thereof and allowed to stand thereon for a period of time sufficient to cause binding of the detecting agent to the analyte on the surface, any affinity-enzymatic compound with unbound detecting agent is removed from the surface, a predetermined amount of hydrogen peroxide is thereafter applied onto the surface in the selected area and the the multilayer analytical element is pressed against the surface in the selected area, the developing agent undergoes oxidation by the hydrogen peroxide in the presence of the peroxidase bound via the binding and detecting agents to the analyte, and the developing agent in oxidized form reacts with the color-producing agent to form a colored product having a color indicative of the level of the analyte. The analytical kit according to the invention can be used in medicine and pharmacology as well as in criminal law.

Title: Depth-first algebraic-codebook search for fast coding of speech
Inventor: ADOUL JEAN-PIERRE
IPC: G10L19/12
Filed: 1996-03-05
Abstract: A codebook is searched in view of encoding a sound signal. This codebook consists of a set of codevectors each of 40 positions and comprising N non-zero-amplitude pulses assignable to predetermined valid positions. To reduce the search complexity, a depth-first search is used which involves a tree structure with levels ordered from 1 through M. A path-building operation takes place at each level whereby a candidate path from the previous level is extended by choosing a predetermined number of new pulses and selecting valid positions for said new pulses in accordance with a given pulse-order rule and a given selection criterion. A path originated at the first level and extended by the path-building operations of subsequent levels determines the respective positions of the N non-zero-amplitude pulse of a candidate codevector. Use of a signal-based pulse-position likelihood estimate during the first few levels enable initial pulse-screening to start the search on favorable conditions. A  selection criterion based on maximizing a ratio is used to assess the progress and to choose the best one among competing candidate codevectors.

Abstract: L'invention concerne un ensemble à barre mobile pour longeron de support d'un four de réchauffage conçu pour réchauffer un produit en acier tel que des brames, des blooms, des barres et des produits semi-finis. Ledit ensemble comporte une barre mobile qui définit une surface de contact supérieure destinée à recevoir un produit à réchauffer, un composant de base présentant une région inférieure contiguë à une région inférieure de la barre mobile, et des moyens de support permettant de monter le composant de base et la barre mobile sur un longeron de support de produit du four dans lequel le produit doit être réchauffé. La barre mobile est en céramique solide résistant aux températures élevées, de faible porosité et présentant une résistance à la compression suffisante pour supporter une partie de la charge du produit lorsqu'il est placé sur celle-ci et sur la barre mobile d'autres ensembles montés sur ce même longeron ou d'autres. Le composant de base est en céramique solide également résistant aux températures élevées et présentant une résistance à la compression suffisante pour supporter une partie de la charge du produit. La céramique constituant le composant de base présente une faible conductivité thermique, ce qui permet de réduire la conduction de l'énergie thermique du produit au longeron sur lequel l'ensemble est monté.
Patent CA-2220035-A1 (CA)
Inventor: RUBIN PHILIP A
IPC: H04N7/16
Filed: 1996-01-02
Abstract: An integrated receiver decoder (IRD) (37), commonly called a set-top box, ha s a global positioning system (GPS) receiver (42). The GPS receiver checks to see if the IRD is at an authorized location and allows descrambling of video  signals only if the location is authorized. A central access control system (Fig. 1), remote from the customers/viewers, has a high quality GPS receiver  (16) and sends some GPS data in the transmission medium used to send video signals to the customers. This GPS data, referred to herein as indirect GPS data, is used by the IRD such that it requires less complexity than otherwis e. The IRD introduces a pseudo-random time delay (56) in generating certain signals such that spoofing (i.e. providing phony signals to the IRD) is much  more difficult. Various components of the IRD are in a common sealed contain er such as an integrated circuit or a smart card such that tampering with the components and spoofing are more difficult.

Title: Electrostatic nozzles for abrasive and conductive liquids
Inventor: LAW S EDWARD
IPC: B05B5/03
Filed: 1996-07-25
Abstract: Air-atomizing induction-charging spray nozzles suited for use with conductive liquids, solutions, suspensions or emulsions. These systems feature a high level of spray charging at low induction-electrode voltage and current. Primary benefits include consistent, reliable operation in harsh agricultural and industrial environments with a wide range of spray formulations, especially those having relatively high concentrations of abrasive and conductive materials. The outer surfaces of the nozzles' body portion (1), near connections to earthed sprayer parts, are maintained floating or at near ground potential. The cover portion (2) surfaces adjacent to the induction electrode (18) are maintained at near the potential of the electrode (18). A highly resistive path between the high and low voltage portions of the nozzle is maintained and the electrode voltage or spray charge level does not decrease significantly as nozzle surfaces become coated with spray or are otherwise contaminated by conductive materials present in the spraying environment.

Title: Radio transmitting apparatus and gain control method for the same
Inventor: HIRAMATSU KATSUHIKO
IPC: H04J13/00
Filed: 1998-03-16
Abstract: Gain control is performed on an input signal to an orthogonal modulator used in a radio transmitting apparatus in such a manner that the level of the input signal falls within the proper operation range of the orthogonal modulator.  At the time of amplifying and outputting the output of the orthogonal modulator, gain control is executed with the reciprocal of a control gain for the input signal to the orthogonal modulator.  Accordingly, the input to the orthogonal modulator of an adaptive array antenna can be compensated within the proper range to ensure the proper operation of the orthogonal modulator.

Patent CA-2238566-A1 (CA)
Inventor: PAULSON PETER O
IPC: G01N29/14
Filed: 1998-05-25
Abstract: Structural cables, for example those formed of a large number of wires and used in suspension bridges or cable-stayed bridges, are monitored by acoustic sensors. Breakage of a wire forming part of the cable gives rise to an acoustic signal.  The signal is recorded and its location is found from the relative times at which it arrives at two sensors. Where sensors are located at the cable anchorage or on bands along the length of a suspension bridge cable, they can also monitor slippage of wires relative to the band or cable anchorage. The system uses high impedance sensors and shielded cable.  The outputs of different sensors are distinguished by a multiplexing technique or by identifying signals.        In another embodiment, sensors placed about the circumference of a cable record signals from wire breaks and the signals are plotted to determine the location of the broken wire within the cross-section of the cable.
