Abstract: Un système permettant d'obtenir et de visualiser des enregistrements vidéo de transactions ayant lieu dans des allées de caisse utilise une caméra de télévision afin de développer des images de signaux vidéo des transactions traitées au niveau de deux allées de caisse ou plus. Un enregistreur situé au niveau de chaque allée génère des signaux numériques représentant des événements ayant lieu au niveau des allées. Un ordinateur répondant aux signaux numériques génèrent un signal de transaction numérique. Un magnétoscope enregistre le signal vidéo d'une caméra et le signal de transaction numérique d'un ordinateur sur une cassette, le signal de transaction numérique étant enregistré dans une certaine relation (par exemple en synchronisation) avec le signal vidéo de la caméra et de manière à ne pas affecter la clarté de chaque image vidéo. Dans un mode de lecture, le magnétoscope génère un signal d'images vidéo de lecture, et l'ordinateur génère un signal de commande de couverture. Un moyen de couverture répondant aux divers signaux génère un signal vidéo composite d'un affichage alphanumérique des informations de transaction numériques relatives à l'allée de caisse voulue recouvrant le signal vidéo, les informations alphanumériques étant positionnées dans le signal vidéo composite de manière à ne pas masquer la partie de l'image vidéo correspondant à l'allée de caisse voulue. Dans un autre mode de réalisation de l'invention, un ordinateur répond aux signaux de l'enregistreur et il génère un signal de stockage vidéo au début d'une transaction ultérieure ainsi qu'un signal résumant la transaction. Le moyen de couverture génère un signal d'image vidéo de récapitulation comprenant des informations de récapitulation de transaction alphanumérique couvrant l'image de la marchandise au début de la transaction.

Patent CA-2133047-C (CA)
Inventor: MEYER THOMAS J
IPC: G01R31/12

Granted: 2002-07-23
Abstract: A non-ferrous current sensor is used to continuously measure the charging current magnitude in step-graded foil and paper insulation systems used on high voltage measurement and control apparatus such as instrument transformers and on the condenser bushings of power transformers and circuit breakers. The low voltage measured signal is conditioned by an electronic circuit such that it modulates a DC signal in a system current control loop to provide continuous remote monitoring and alarm functions. Remote power is supplied to the sensor and conversion circuits through the current loop. Alarm level thresholds and alarm time delay are embodied in a control device which may be located in a remote location, away from the high voltage equipment. Step-graded insulation systems form a capacitively divided circuit between the high potential and ground. As the dielectric between the foil layers breaks down, the total capacitance of the insulation system increases, producing an increase in the charging current. The sensor detects changes in the charging current through the insulation ground conductor, indicating the degradation of the dielectric properties between the foil layers. Continuous monitoring of the alarm relay contacts provide a means for reporting abnormal conditions and initiating event-based maintenance procedures. The modulation of a standard 4-20 mA current control loop allows for a multiplicity of monitoring equipment to be added to the system for additional data collection and reporting.

Title: Antibodies specific for a haemostatic protein, their use for isolating intact protein, haemostatic compositions devoid of proteolytic cleavage products of the protein
Inventor: MERTENS KOENRAAD
IPC: B01J20/281
Filed: 1993-08-26
Granted: 2008-09-23
Abstract: Methods for the generation of Ca2+ -independent antibodies against blood coagulation factors, employing an antibody selection strategy based on small peptides that are comprising target sequences for limited proteolysis. These antibodies, which substantially distinguish between intact and cleaved species of said haemostatic protein, provide novel tools for the isolation of intact haemostatic proteins. By virtue of the absence of cleavage products that usually are associated with side-effects or reduced efficacy, these intact proteins may serve as improved agents in therapeutic compositions for the treatment of haemostatic disorders.

Title: System and method for automated interpretation of input expressions using novel a posteriori probability measures and optimally trained information processing networks
Inventor: BURGES CHRISTOPHER JOHN
IPC: G06V30/10
Filed: 1995-06-20
Granted: 2000-01-25
Abstract: A method and system for forming an interpretation of an input expression, where the input expression is expressed in a medium, the interpretation is a sequence of symbols, and each symbol is a symbol in a known symbol set. In general, the  system  processes  an  acquired  input  data  set representative of the input expression, to form a set of segments,  which  are  then  used  to specify  a  set  of consegmentations.  Each consegmentation and each possible interpretation for the input expression is represented in a data  structure.    The  data  structure  is  graphically representable by a graph comprising a two-dimensional array of nodes arranged in rows and columns and selectively connected by directed arcs.  Each path, extending through the nodes and along the directed arcs,  represents one consegmentation and one possible interpretation for the input expression.  All of the consegmentations and all of the possible interpretations for the input expression are represented by the set of paths extending through the graph. For each row of nodes in the graph, a set of scores is produced for the known symbol set,  using a complex of optimally trained neural information processing networks. Thereafter the system computes an a posteriori probability for  one  or more  symbol  sequence  interpretations.    By deriving  each  a posteriori probability  solely  through analysis of the acquired input data set, highly reliable probabilities are produced for competing interpreta-tions for the input expression.   The principles of the present invention can be practiced with cursively written character-strings of arbitrary length and can be readily adapted for use in speech recognition systems.

Title: A method and apparatus for converting text into audible signals using a neural network
Inventor: KARAALI ORHAN
IPC: G06F15/18
Filed: 1995-03-21
Granted: 2000-06-13
Abstract: Text may be converted to audible signals, such as speech, by first training a neural network using recorded audio messages (204). To begin the training, the recorded audio messages are converted into a series of audio frames (205) having a fixed duration (213). Then, each audio frame is assigned a phonetic representation (203) and a target acoustic representation, where the phonetic representation (203) is a binary word that represents the phone and articulation characteristics of the audio frame, while the target acoustic representation is a vector of audio information such as pitch and energy. After training, the neural network is used in conversion of text into speech. First, text that is to be converted is translated to a series of phonetic frames of the same form as the phonetic representations (203) and having the fixed duration (213). Then the neural network produces acoustic representations in response to context descriptions (207) that include some of the phonetic frames. The acoustic representations are then converted into a speech wave form by a synthesizer.
