Abstract: A method for transmitting measured information from a measuring computer to a control computer of a measuring system, the control and measuring computers being interconnected via a telecommunications network, includes combining measured data into characteristic values having a lower volume than the measured data. The characteristic values are transmitted from the measuring computer to the control computer.

Abstract: A method for measuring unidirectional transmission properties, e.g., packet delay, delay-time fluctuations, and results derivable therefrom, in a telecommunications network. Test packets are transmitted from a first measuring computer via a measurement path to a second measuring computer. The first measuring computer records the departure time of the outgoing test packet. This clock time is transmitted along with the test packet. The second measuring computer records the arrival time of the test packet. In a subtraction operation between the departure time from the first measuring computer and the arrival time in the second measuring computer, the delay time of the test packet, i.e., the measuring result, is determined. To determine the measuring result, the two measuring computers are synchronized in time by satellite systems, e.g., GPS (global positioning system), in that the clock time is continuously transmitted to both measuring computers.

Abstract: A method for automatically indicating status information of a measuring system via an output device includes assigning status information to respective status ranges according to at least one predetermined condition, the status ranges being limited by at least one threshold value. The status ranges are individually outputted. The status information is automatically updated at a predetermined time interval.

Abstract: A method for time synchronization of a number of measuring computers cooperating over a telecommunications network includes providing a number of time sources associated with one of the measuring computers. Each of the time sources has a different accuracy and can provide a time stamp. Using the first measuring computer, one of the time sources is selected as a function of the accuracy of the time source.

Abstract: A method for transmitting measured information from a measuring computer to a control computer of a measuring system, the control and measuring computers being interconnected via a telecommunications network, includes combining measured data into characteristic values having a lower volume than the measured data.

Abstract: The invention relates to a method for temporal synchronisation of at least two measuring computers (28, 36, 46), cooperating over a telecommunication network (10) such as internet, intranet or similar in which a highly accurate timestamp is required for each measurement process. The invention is characterised in that each measuring computer (28, 36, 46) is provided with several time sources with varying accuracy for reading off the timestamp from a time source and the selection of the time source by the measuring computer (28, 36, 46) is carried out depending an the accuracy of the time source.

Abstract: The present invention is directed to a method for measuring unidirectional transmission properties, such as packet delay (Dnetwork), delay-time fluctuations (tjitter), and results derivable therefrom, in a telecommunications network (10), such as the Internet, an intranet, or the like. In the telecommunications network, a plurality of switching devices (12 through 22) and other devices (34, 36, 38) are interconnected via transmission lines (24). Between at least two measuring computers (26, 28), test packets are transmitted from the first measuring computer (26) via a measurement path (32) to the second measuring computer (28). The first measuring computer (26) records the departure time (t1) of the outgoing test packet. This clock time is transmitted along with the test packet. The second measuring computer (28) records the arrival time (t2) of the test packet.

Abstract: This invention relates to an arrangement for projecting cantilever sections of multi-sectional bridge supporting structures of steel or prestressed concrete forming the superstructure of the bridge which is supported on bridge piles. The arrangement includes at least one traveling auxiliary beam movably carried on and arranged above the superstructure for spanning between superstructure sections. Two concreting scaffolds each comprising a supporting part having crossbeams and rollers are arranged above the superstructure and carry a platform which is arranged below the superstructure for carrying casings to extend the projecting superstructure sections. A transport device is movably carried on the auxiliary beam and supports the concreting scaffolds for transport between superstructure sections and from the end of a completed section to a bridge pile for beginning construction of a new section.
