Patent number: 7920683Abstract: A testing device and a method for verifying the charge invoicing for a communications device according to time unit intervals is provided. A testing device, which can simulate at least one calling analog terminal and at least one called terminal, is connected to a network node that generates time pulses. At least one predetermined test communications connection is set up and terminated over at least the one network node. Further, the time interval between the beginning of the test communications connection and the generation of a first time pulse is determined and verified to ascertain whether the determined time interval is located within a first predetermined time domain. During the existing test communications connection, time unit intervals of successive time pulses are measured and compared with a predetermined time interval. A further method involving receipt of additional time pulse(s) after the termination of the test communications connection is also provided.Type: GrantFiled: July 17, 2003Date of Patent: April 5, 2011Assignee: Deutsche Telekom AGInventors: Monika Schmidt, Ernst Schneider

Patent number: 7302045Abstract: A method and system for verifying the connection-related communications data registered by a network node, where the connection-related communications data are used for the calculation of charges includes establishing at least one predetermined test communication connection. By clearing the predetermined test communication connection via the network node and registering a time of an event, the system and method registers the time of at least one additional event for calculating charges at a predetermined measuring point lying outside of the network node. A systematic temporal measuring error is determined. A reference data record containing time-related data and a connection-related communications data record generated is generated. The method corrects the time-related data of the reference data by the ascertained systematic temporal measuring error and compares the reference data record to the connection-related communications data record to determine if a difference lies within a predetermined range.Type: GrantFiled: July 17, 2003Date of Patent: November 27, 2007Assignee: Deutsche Telekom AGInventors: Monika Schmidt, Ernst Schneider

Patent number: 5098381Abstract: A catheter for treating an obstructed blood vessel comprises an elongated tubular body having an internal lumen, a proximal portion and a distal portion, and includes an inflatable dilatation element on the distal portion thereof. The dilatation element is in communication with the lumen and is adapted to be inflatable and deflatable by the application of a suitable therapeutic tissue dissolving fluid pressurized within the lumen. The dilatation element includes a wall having microporus openings adapted to be permeable by the fluid applied to inflate the dilatation element. The fluid, which is pumped into the interior space of the dilatation element, under sufficient pressure, presses through the microporus wall directly on and into the adjacnet tissue. The fluid tends to dissolve the tissue, thereby treatment time is considerably shortened and the long-term success of the treatment is improved, since the impairing tissue is not only dislodged but also dissolved from the vessel.Type: GrantFiled: July 19, 1991Date of Patent: March 24, 1992Assignee: Schneider EuropeInventor: Ernst Schneider

Patent number: 4018863Abstract: Polytetrafluoroethylene (PTFE) pipes, which may have a supporting metal mandrel placed therein, are flanged. To this end, use is made of a first implement which is a rigid annular plate having a frustoconical element and a bevelled cylindrical plug slightly smaller in diameter than the PTFE-pipe centrally mounted thereon. The first implement is heated once to 180.degree.-210.degree. C and forced into contact with the PTFE-pipe so that the plug opens thereinto. The PTFE-pipe and the first implement projecting thereinto are caused to rotate for 0.5-3 minutes at a speed of 5-10 rpm and under a contact pressure of 5-20 kg/cm.sup.2 of pipe surface area to be flanged whereby the free end of the PTFE-pipe is flared. The first implement is removed and replaced by a second implement which is a rigid annular plate having a bevelled cylindrical plug substantially equal in diameter with the PTFE-pipe centrally mounted thereon. The second implement is heated once to 180.degree.-210.degree.Type: GrantFiled: September 30, 1974Date of Patent: April 19, 1977Assignee: Hoechst AktiengesellschaftInventors: Ernst Schneiders, Wilhelm Klocker
