Patent number: 7177281Abstract: The invention discloses removal of ATM cells from an ATM communications device. A first algorithm is provided by means of which, with the exception of a first and a last ATM cell in a frame, all newly arriving cells in the frame are removed. A second algorithm is provided by means of which all the ATM cells in a frame, from a first cell to a last cell, are removed on arrival in a queue from the ATM communications device. At a start of a transmission process, a user indicates a maximum number of ATM cells per frame, and the ATM cells using the number are transmitted when the maximum number is exceeded, the associated frame is discarded or the first algorithm is used. The invention solves this problem by defining rules whose application results in this method now being used only to a very limited extent.Type: GrantFiled: September 30, 2005Date of Patent: February 13, 2007Assignee: Siemens AktiegesellschaftInventors: Herbert Heiss, Raimar Thudt

Patent number: 7103513Abstract: A standard, modularly expandable system is for measuring and analyzing far spread signals from industrial processes consisting of several partial processes in an essentially feedback-free and synchronous manner. Random signals occurring in the partial processes are detected by way of measuring heads, optionally provided with a time stamp, and transferred to a measuring bus system in a predefined form as measuring signals or time signals. The measuring bus system is not identical with existing automation-related bus systems. The measuring signals and/or time signals are further processed by data concentrators. Evaluation units and/or display units that are local or indefinitely removed from the industrial process make it possible to further process or visualize measuring signals and/or time signals. The measuring heads detect a standard time signal such as the one of the global positioning system.Type: GrantFiled: January 14, 2003Date of Patent: September 5, 2006Assignee: Siemens AktiegesellschaftInventors: Rupert Maier, Ralf Sykosch

Patent number: 6434925Abstract: A gas and steam turbine plant includes a waste-heat steam generator which is located downstream of a gas turbine on the flue-gas side and which has heating surfaces that are connected into a water/steam circuit of a steam turbine. A gasification device is located upstream of a combustion chamber of the gas turbine through a fuel line, for the integrated gasification of a fossil fuel. The gas and steam turbine plant is to be operated with particularly high plant efficiency even when oil is used as the fossil fuel. Thus, a heat exchanger is connected on the primary side into the fuel line upstream of a mixing apparatus for admixing nitrogen to the gasified fuel, as seen in the direction of flow of the gasified fuel. The heat exchanger is constructed on the secondary side as an evaporator for a flow medium.Type: GrantFiled: April 9, 2001Date of Patent: August 20, 2002Assignee: Siemens AktiegesellschaftInventors: Frank Hannemann, Ulrich Schiffers

Patent number: 6310537Abstract: The broadcast code (I) is received by the receiver (E) fitted in the motor vehicle, which receiver (E) controls the relevant lock or the relevant locks—after a comparison of the received code (I) with digits stored in the receiver (E) and correlating with the code (I) or with the series of codes (I). The code (I) is initialized as a permanent code or interchangeable code at least on the occasions when the motor vehicle is first used and, possibly when changes are later made to the code (I), is reinitialized. For (re)initialization, the receiver (E) must first be switched by a signal to its (re)initialization readiness, before the receiver (E) can be (re)initialized. The motor vehicle has a diagnostic interface (D) for the electrical testing of motor vehicle units. The receiver (E) is only switched to its (re)initialization readiness by a signal fed to it (E) via the diagnostic interface (D).Type: GrantFiled: December 6, 1996Date of Patent: October 30, 2001Assignee: Siemens AktiegesellschaftInventors: Anton Bachhuber, Maximilian Kern, Christian Schneider

Patent number: 5442647Abstract: Bit falsifications occur in the switching networks of digital communication systems in the transmission through these switching networks of bit streams composed of a plurality of information words. By correcting these bit errors, only a correctly transmitted information word is forwarded to a destination subscriber after the transmission given redundantly executed and activated switching network halves. Whether an information word was correctly transmission is determined after the transmission with a combined parity bit check as well as bit-by-bit comparison to the information word transmission in parallel. It is assured that bit falsifications of the units (holding memories) participating in the transmission process are detected and corrected.Type: GrantFiled: May 24, 1993Date of Patent: August 15, 1995Assignee: Siemens AktiegesellschaftInventor: Norbert Loebig

Patent number: 4965857Abstract: A method for generating an FSK-modulated optical signal with an optical two-filter FSK super-heterodyne receiver. The optical signal has two different polarization conditions that are orthogonal to one another. Due to orthogonal conditions, polarization-independent reception is possible. Synchronized polarization shifting occurs to generate a polarized modulated optical signal having alternating orthogonal polarization conditions. A delay stage for delaying the switching signal by one-half a clock period ensures accurate synchronization. The frequency shift of the FSK-modulated signal can be freely selected while maintaining excellent bandwidth characteristics and optimum sensitivity.Type: GrantFiled: September 26, 1989Date of Patent: October 23, 1990Assignee: Siemens AktiegesellschaftInventors: Franz Auracher, Alfred Ebberg, Bernd Noll, Eckhard Meissner, Hermann-Johann Rodler
