  • Publication number: 20020143919
    Abstract: The invention relates to a network comprising a plurality of switches which are combined to respective sub-networks and coupled to fixed terminals or, via base stations, to mobile terminals. Each switch comprises for the connection setup from a terminal to a mobile terminal at least a table which contains an assignment of the home address of a mobile terminal to its visitor's address and to the sub-network of the switch assigned to the mobile terminal.

  • Patent number: 6373918
    Abstract: The present invention relates to a method for automatically detecting contours of, for example, shutters or implants in an X-ray image. A number of closed paths is derived from the X-ray image, one of said closed paths being selected, in dependence on the contrast along the closed paths, as the contour. The closed paths may be derived from a set of line candidates on which contour pixel candidates are situated. The contour pixel candidates can be derived from a high-pass or gradient version of the X-ray image.

  • Patent number: 6252931
    Abstract: The invention relates to an image processing method in which an original image is first decomposed into a series of detail images, with each of which there is associated a respective spatial frequency range, low contrasts being enhanced before assembly of a final image from the images which are produced by the decomposition and are subsequently modified. The modification of the detail images is performed in dependence on the relevant image value as well as in dependence on the mean image value and/or the variation of the image values in a window around the relevant pixel.

  • Patent number: 5774539
    Abstract: A communication system includes subscriber terminals which can be coupled via at least one switch, and to which subscriber terminals, several call numbers can be assigned for which telecommunication parameters are definable. The subscriber terminals each store respective telecommunication parameters. In the case of a change of assignment of a subscriber call number from a first subscriber terminal to a second subscriber terminal, the telecommunication parameters belonging to the subscriber call number are transmitted to the second subscriber terminal. The communication system is preferably implemented in ISDN switching systems with ISDN telephones as terminals.
