Patent number: 6611194Abstract: A secure and efficient key management system for utilizing a service key for retrieving service data transmitted to a terminal from a service center via a communication channel. A service key is inserted into a terminal and is used to enable the decryption of the received encrypted service data from the service center. The service center requests and obtains a coding key from a trust center when the service center receives a service key transmission request from the from the terminal. The service key transmission request includes a terminal identity number. The service center forwards the request to the trust center which returns the coding key associated with a decoding key corresponding to the specific terminal. The service center encrypts the service key with the coding key and transmits the service key to the terminal. The service key is decrypted in the terminal using the decoding key input to the terminal by the terminal manufacturer.Type: GrantFiled: October 21, 1999Date of Patent: August 26, 2003Assignee: Mannesmann AGInventors: Stefan Vieweg, Matthias Jungemann, Maik Schmidt, Michael Thoenissen

Patent number: 6585299Abstract: A pipe joint with a sleeve element, which has an internal thread, and with a spigot element, which has an external thread which can be screwed to said internal thread. One element has a constant pitch throughout and the other element, with two sections extending in each case from the ends of the threaded length is likewise provided with a constant pitch. The other element has more than two sections with a pitch which is constant within the section but is different from the first-mentioned element, it being the case that the pitch difference at least of one section is in the opposite direction, in terms of sign, to the rest of the sections. The pitch difference of one section is at least double that of the adjacent sections and in the screwed-together position, in the section with the large pitch difference, the thread play and the thread tolerances are compensated and the load flank of one corner tooth of this section, with the guide flank of the other corner tooth, produces the basic bracing.Type: GrantFiled: March 27, 2000Date of Patent: July 1, 2003Assignee: Mannesmann AGInventors: Erich Quadflieg, Gerhard Krug, Friedrich Lenze, Martin Schlüter

Patent number: 6563820Abstract: The invention relates to a process and a device for forwarding non-speech-bound information between a mobile communications network and any other communications network. To allow data packets data to be sent, regardless of its receiver address, to the involved communications network, the transmission route for the forwarding of the information is established as a function of the identification code of the data packet one logical transmission channel is assigned to each identification code, and each logical transmission channel is bound to exactly one physical transmission channel. For this purpose, an identification code is assigned to each incoming logical transmission channel. The logical transmission channels from the mobile communications network then are permanently connected to selected outgoing physical transmission channels to different communications networks.Type: GrantFiled: April 8, 1998Date of Patent: May 13, 2003Assignee: Mannesmann AGInventor: Rainer Griess

Patent number: 6541974Abstract: A device for measuring the filling level of a medium—for example hydrogen—in a storage container of a storage device—for example a tank system. To provide a simple and direct possible way of accurately determining the filling level of the storage container even without knowing the amount of medium already discharged or irrespective of uncontrollable losses, the device is designed as a measuring device for measuring the nuclear magnetic resonance of the medium located in the storage container. For this purpose, the device has a measuring head with, for example, a permanent magnet and a measuring coil, via which a static magnetic field and an electromagnetic alternating field are generated in the measuring head. The electromagnetic alternating field is generated in a transmitter, which is connected to the measuring head by a bridge circuit.Type: GrantFiled: February 20, 2001Date of Patent: April 1, 2003Assignee: Mannesmann AGInventor: Walter Schütz
