Patent number: 11283636Abstract: A method for enabling a charging of packet switched data transfer between an authorized customer and a network. The method includes transferring a total data volume via at least a first data path and a second data path between an equipment related to the authorized customer and a hybrid access aggregation point (HAAP) as an access to the network. Each of the at least a first data path and a second data bath use a different access technology for transferring its respective part of the total data volume. The total data volume is determined as a sum of the respective parts of the total data volume transferred in both the first path and the second path. The total data volume is used by a central charging unit for a charging.Type: GrantFiled: January 12, 2016Date of Patent: March 22, 2022Assignee: DEUTSCHE TELEKOM AGInventors: Cornelius Heidemann, Gerrit Voehringer, Christoph Ludwig

Patent number: 7678679Abstract: A growth material that grows selectively on the vertical sidewalls of a vertical device forms sidewall spacers on substantially vertical sidewalls of the vertical device that is disposed on a horizontal substrate surface of a semiconductor substrate. A spacer-like seed liner may be provided on the vertical sidewalls of the vertical device to control selective growth. The vertical device may be a gate electrode of a field effect transistor (FET). With selectively grown sidewall spacers, heavily doped contact regions of the FET may be precisely spaced apart from the gate electrode. The distance of the heavily doped contact regions to the gate electrode does not depend from the height of the gate electrode. Distances of more than 150 nm between the heavily doped contact region and the gate electrode may be achieved so as to facilitate the formation of, for example, DMOS devices.Type: GrantFiled: May 1, 2006Date of Patent: March 16, 2010Assignee: Qimonda AGInventors: Dirk Manger, Jyoti Gupta, Christoph Ludwig, Hans Lindemann
