  • Patent number: 7161980
    Abstract: A system and method for processing received transmission signal(s) adapted to be used in high rate communication systems without impairing the received signal energy and without additional expensive components. The system and method are adapted to transmission system(s) having at the receiver-side a compound system of a feed-forward equalizer (FFE) and a subsequent decision feedback equalizer (DFE). A feed forward equalization and/or a decision feedback equalization is performed on the received high rate signal by deriving adaptation information from the equalized signal after a signal decision is performed for adjusting all intended feed forward equalization and/or decision feedback equalization coefficients and/or table entries in dependence on said information.

  • Patent number: 6857358
    Abstract: The invention relates to a device and a method for marking cigarette packets, comprising a transport device for conveying at least one cigarette packet to a marking station for marking cigarette packets, and the following features: the transport device grasps a batch of adjacent, aligned cigarette packets and moves them to the marking station, where the transport device releases the batch; and the released cigarette packets are marked on at least one exposed area.

  • Publication number: 20050002278
    Abstract: The present invention relates to a radio clockwork mechanism which includes a movable hour hand and a mechanism for determining which hour the hour hand is currently indicating. That determining mechanism comprises hour-contact arches, a scanning mechanism, and a querying mechanism. The hour-contact arches are assigned to respective hours and are spaced apart a circular path. The scanning mechanism includes an hour-scanning device which is movable synchronously with the hour hand for sequentially scanning the hour-contact arches and giving a currently scanned hour-contact arch and an electrical potential different from all other hour-contact arches. The querying mechanism queries the hour-contact arches for determining which has the different electrical potential.

  • Publication number: 20040260477
    Abstract: according to one aspect of the present invention, regulatory classification of a product is performed by using a computer to search a database for at least one classification covering the product; outputting a classification if the classification is found in the database; and, if no classification is found, ascertaining at least one classification in a different manner and entering any ascertained classifications to the database.

  • Patent number: 5616970
    Abstract: In a method and a circuit arrangement for driving semiconductor switches in a series circuit, in which a voltage limiting device is assigned to each semiconductor switch, the power losses of the voltage limiting devices are detected by a control equipment for equalizing the voltage distribution across the semiconductor switches. The control equipment generates modified control pulses for each semiconductor switch from a common control pulse on the basis of the detected power losses of the voltage limiting devices. By this means, the power loss of the voltage limiting devices is controlled to a minimum.
