OBJECT EXTRACTION IN COLOUR COMPOUND DOCUMENTS / CANON KABUSHIKI KAISHA Disclosed is a computer implemented method of text extraction in colour compound documents. The method connects similarly coloured pixels of an image of a colour compound document into connected components (CCs); classifies each CC as either text or non-text; refines the text CC classification for each text CC using global colour context statistics; groups text CCs into text blocks; recovers misclassified non-text CCs into a nearby text block; and removes extraneous CCs from each text block using local colour context statistics to thereby provide the extracted text in the text blocks. Also disclosed is a computer implemented method of locating graphics objects in a colour compound document image. The method connects similarly coloured pixels of said image into connected components (CCs) and placing the CCs in an enclosure tree; classifies (330,730) each CC into one of a plurality of classes wherein at least one class (862) represents salient graphics components; identifies (1140) a graphics container (441) to perform semantic analysis for each CC of said class representing salient graphics components; profiles (1170) descendents of said graphics container in said tree to obtain semantic context statistics; and decides (1710) whether the graphics container contains a whole or part of a graphics object based on said semantic context statistics. |

POWER SUPPLY UNIT DC-DC CONVERSION / PHILIPS CORPORATE INTELLECTUAL PROPERTY GMBH, BE The invention relates to a power supply unit for direct current to direct current DC-DC conversion having multiple outputs. Such power converters comprise a DC-AC converter 100, a transformer 200 and a plurality of AC-DC onverters 300-i i=1...n each for generating an individual DC-output voltage Vi being provided to a respective load impedance 330-i. Lossy components in said transformer and said AC-DC converters cause undesired voltage drops causing undesired fluctuations of the DC-output voltages. A reduction of said fluctuations of said DC-output voltages is achieved by feeding-back the DC-output voltage of at least one AC-DC converter to said DC-AC converter. Starting from that prior art it is the object of the invention to improve a power supply unit for DC-DC conversion such that a more uniform sharing of the fluctuations of the output voltages is achieved easily and cheaply. This object is achieved according to the present invention by connecting an auxiliary impedance 340 in series to the load impedance connected to one of said AC-DC converters.La presente invention concerne une unite d'alimentation pour la conversion de courant continu-continu comportant une pluralite de sorties. De tels convertisseurs de puissance comporte un convertisseur CC-CA (100), un transformateur (200) et une pluralite de convertisseurs CA-CC (300-i i=1 n) chacun permettant le generation d'une tension de sortie individuelle en courant continu (Vi) fournie a une impedance de charge respective (330-i). Des composants a perte dans ledit transformateur et dans lesdits convertisseurs CA-CC provoquent des chutes de tension indesirables entrainant des fluctuations dans les tensions de sortie en courant continu. On peut obtenir une reduction desdites fluctuations desdites tensions de sortie en courant continu-continu par realimentation de la tension de sortie en continu d'au moins un convertisseur CA-CC vers le convertisseur CC-CA. A partir de cet etat de la technique l'invention propose l'amelioration d'une unite d'alimentation pour la conversion CC-CC de maniere a realiser aisement une repartition uniforme des fluctuations de tensions a moindre cout. Cela est realise selon la presente invention par la connexion d'une impedance auxiliaire (340) en serie a l'impedance de charge reliee a l'un desdits convertisseurs CA-CC.

MULTIPLEX MODE AMPLIFIER / YOKOGAWA HEWLETT PACKARD LTD (PURPOSE) To increase the power efficiency, by selecting a linear mode or a switching mode in response to the level of an input signal. (CONSTITUTION) The signal CC transmitted through a line 45 is supplied to an amplifier 310 which works in a linear mode as well as to an amplifier 330 which works in a switching mode respectively. The output signals of both amplifiers are supplied to a mode selector 3700. The selector 3700 supplies the output of a pulse width modulator 3500 to a power amplifier 390 when the amplitude of the signal CC is larger than 1V on the line 45. While the output signal of the amplifier 310 is supplied to the amplifier 3900 when the amplitude of the signal CC is smaller than 0.5V. When the amplitude of the signal CC is set between 0.5∼1V, the selection has a hysteresis action. A switching mode is used for such as big action as to drive a servomotor; while a linear mode is used for a fine adjustment. Thus, the power efficiency is increased. |
