Title: Procede et appareil pour decoder des images de codes a barres en utilisant l'information des lignes de balayage anterieures
Inventor: SURKA STEFAN
IPC: G06K7/00
Filed: 1995-01-20
Abstract: L'invention concerne un procédé et un appareil pour décoder une image en pixels représentant un symbole de code à barres. On balaye un symbole de code à barres suivant une première ligne de balayage pour déterminer un premier jeu de valeurs de caractère candidates, chaque valeur de caractère candidate de ce premier jeu ayant une première valeur d'erreur associée. Lorsque le balayage suivant la première ligne de balayage ne réussit pas la lecture du symbole de code à barres, alors le symbole de code à barres est balayé suivant une seconde ligne de balayage différente pour déterminer un second jeu de valeurs de caractère candidates, chaque valeur de caractère candidate de ce second jeu ayant une valeur d'erreur associée. On compare ensuite les valeurs d'erreur correspondantes associées avec le premier et le second jeux de valeurs de caractère candidates. Pour chaque paire de valeurs de caractère candidates correspondantes du premier et du second jeux, on choisit la valeur des caractères candidate ayant la valeur d'erreur associée la plus petite. Un troisième jeu de valeurs de caractère candidates est formé conformément aux valeurs de caractère candidates sélectionnées et le symbole de code à barres est décodé conformément au troisième jeu de valeurs de caractère candidates.

Title: Controlled switching
Inventor: BIRRELL PETER
IPC: H03K17/13
Filed: 1996-10-28
Abstract: A  method  of  and  apparatus  for  controlling  the opening  and/or  closing  of  contacts  of  an  electro-mechanical  switching  device  in an alternating  current circuit.    Detection  is  made  for  the  existence  of  a voltage having a level which is indicative of a back emf in a load circuit immediately following opening of the contacts,  and if  such a voltage level  is detected an incremental  adjustment  is made  in the phase angle at which successive actuations of the contacts are effected. This  procedure  is  repeated  under the  control  of  a microprocessor until such time as the voltage which is indicative of back emf reduces to zero, this providing an indication that contact opening is occurring at a time corresponding to zero current crossing in the alternating current waveform.

IPC: G06T11/60
Filed: 1997-03-07
Abstract: A processor is provided with a first set of digital information that includes a first, resolution-independent structured representation of a document.  This first representation is one from which various image collections (e.g., sets of page images) can be obtained, each such image in each such collection having a characteristic resolution. From the first set of digital information, the processor produces a second set of digital information that includes a second, resolution-dependent structured representation of the document.  The second structured representation is a lossless representation of a particular one of the image collections obtainable from the first structured representation, and it includes a set of tokens and a set of positions. The second set of digital information is produced by extracting the tokens from the first structured representation, and by determining the positions from the first structured representation. Each extracted token includes pixel data representing a subimage of the particular image collection. Each position is a position of a token subimage in the particular image collection. At least one of the token subimages contains multiple pixels and occurs at more than one position in the image collection. The second set of digital information thus produced can be made available for further use (e.g., distribution, transmission, storage, subsequent reconversion into page images). Applications of the invention include high-speed printing and Internet (World Wide Web) document display.
