Patent number: 6697274Abstract: An open-loop and closed-loop control method is proposed for a single-phase or polyphase three-point converter which is connected to a DC voltage intermediate circuit, having two series-connected main switches/inverse diodes between each DC voltage connection and each load connection. The common junction point of the two inner main switches forms the load connection. An active clamped switch with an inverse diode is connected between each common junction point of an inner main switch and an outer main switch and the center tap of the DC voltage intermediate circuit. As a result of which, two possible paths are formed for connecting a load connection to the center tap. Irrespective of the direction of the load current, at least one of the two active clamped switches (T5, T6) is connected to the center tap together with at least one inner main switch for connection of a load connection.Type: GrantFiled: March 13, 2003Date of Patent: February 24, 2004Assignee: ABB Research Ltd.Inventors: Steffen Bernet, Thomas Brückner

Patent number: 6401086Abstract: The method enables the sentence-based automatic summarization of a text on a computer. For this purpose, subject-related lexica are used that provide a relevance measure for each word contained therein. Each sentence of the text to be summarized is processed word-by-word, and for each word an individual word frequency, weighted with the relevance measure, is cumulated. For the summarization, the n sentences having the greatest probability that they belong to the summary are assembled, whereby n is a predeterminable reduction measure.Type: GrantFiled: September 16, 1999Date of Patent: June 4, 2002Assignee: Siemens AktiengesellschaftInventor: Thomas Brückner

Patent number: 6295543Abstract: The text to be classified is compared with the contents of a relevance lexicon in which the significant words of the texts to be classified per text class and their relevance to the text classes is stored. The fuzzy set is calculated which specifies for the significant words of the text to be classified, their occurrence per text class and their relevance to the text class. A probability calculation is used for determining the probability with which the fuzzy set occurs per class for the corresponding class. The class having the highest probability is selected and the text is allocated to this class.Type: GrantFiled: October 5, 1998Date of Patent: September 25, 2001Assignee: Siemens AktiengesellshaftInventors: Hans-Ulrich Block, Thomas Brückner
