Patent DE-4140017-A1 (DE)
IPC: H04J3/06
Filed: 1991-12-04
Abstract: A process is disclosed for operating computing units in communication with each other by serial data transfer over a data bus. Each computing unit has its own clock generating system and the computing units exchange timing information over the data bus. In order to generate a common time base using the transfer protocol valid for the system, a time recording start signal is at first supplied to the data bus; then each computing unit stores its own time value when it identifies the time recording start signal, transfers the stored own time value at a later moment in time to the other computing units and stores the time values received from the other computing units. Each computing unit then compares its own stored time value to the stored time values of the other computing units and calculates the present time value of the other computing units taking into account its own present time value. Each computing node can thus very accurately ascertain the relation between its local time and the local time base of the other computing units or of a reference node, without having to adjust or correct the local time base.

Patent DE-4190742-A1 (DE)
IPC: G05B13/02
Filed: 1991-04-10
Abstract: The invention relates to a process and circuit arrangement for correcting the frequency response of a signal and/or affecting interference in a regulating circuit. Here, high frequencies are summed in the signal and/or the transfer behaviour of the signal is transformed and/or the signal is separated into several signals. For the purposes of implementation a delay compensating circuit and/or a transfer circuit and/or a selection circuit is arranged at the output of a transmission component. To affect interference in a regulating circuit with a measuring signal formed by a measuring device and having a command variable whereby the measuring signal of the control value is transformed after a fifth summation point into a delay-free proportional signal, a difference signal is formed with the signal of the command variable in a first summation point and sent to a regulator for interference compensation. The interference-free signal with respect to the measuring device is transformed into a delay-free proportional signal with respect to the control range and all the interference signals acting on the control value are converted into a supply interference signal and sent to a second summation point. The signal of the control variable is also sent to the second summation point and a dynamically corrected signal for the regulation deviation and, by adaptation and lock-on, a signal improving the control and interference transmission ratio (improved signal) is formed. The improved signal and that of the control variable are adapted as a correcting signal and summarily sent to the second summation point while its algorithmically optimised output signal and the output signal of the regulator are set to a third summation point. The setting value signal is fed back to the third summation point to optimise and limit its output signal via the setting device and sent to the fourth summation point and to the input of the control section.
