PTP messages to the master clock may be selectively relayed based on whether the PTP messages have been received from the valid one of the redundant networks.

Abstract: The disclosed embodiments related to a clocked memory system which performs a calibration operation at a full-rate frequency to determine a full-rate calibration state that specifies a delay between a clock signal and a corresponding data signal in the clocked memory system. Next, the clocked memory system uses the full-rate calibration state to calculate a sub-rate calibration state, which is associated with a sub-rate frequency (e.g., ½, ¼ or ? of the full-rate frequency). The system then uses this sub-rate calibration state when the clocked memory system is operating at the sub-rate frequency. This calculation of the sub-rate state calibration states eliminates the need to perform an additional time-consuming calibration operation for each sub-rate.

Abstract: Systems and methods are provided to perform dead time correction. An observed ion count rate is obtained using a non-paralyzable detection system of a mass spectrometer. The detection system includes an ion detector, a comparator/discriminator, a mono-stable circuit and a counter. The non-paralyzable detection system exhibits dead time extension at high count rates. The extension of the dead time occurs because the mono-stable circuit requires a rising edge to trigger and can only be triggered again after the output pulse from the comparator/discriminator has gone low. This allows a second comparator/discriminator pulse arriving just before the end of the dead time started by a first comparator/discriminator pulse to extend the dead time to the trailing edge of the second comparator/discriminator pulse. A true ion count rate is calculated by performing dead time correction of the observed ion count rate.

The measured value (yE) is determined based on a corrected point in time (TK) which is determined by correcting the point in time (TM) that is associated with the measurement by using a correction term that accounts for a dead time (TT) of the measuring device.

Abstract: Techniques for sensor data time alignment are described. According to one or more embodiments, sensor data from different sensor systems is time-aligned to a reference time base. For instance, reference time values may be propagated to sensor systems to enable the sensor systems to mark sensor data based on the reference time values.

An alignment policy, for example, accounts for a difference between a time base of a sensor system and a reference time base. Thus, sensor data from different sensor systems may be aligned to common time values in a variety of different ways.

Abstract: In an analyzing system including a commanding unit for sending a command and an executing unit for executing a processing upon receiving the command, a processing instruction may not be executed at the right time due to a heavy traffic of information and other factors. In order to solve this problem, in a preparative separation system 1 according to the present invention, a PC 20 provides the execution time for starting/finishing the fractionation processing to a controller 18. Therefore, even in the case where the time of the PC 20 and that of the controller 18 are not synchronized, the controller 18 can accurately set the execution time for starting/finishing the fractionation in a preparative separation unit 16. A piping 17 may be placed so that the traveling time of sample components is sufficiently larger than the delay time of signals due to the signal transfer lag and other reasons. This can absorb the delay time, allowing the units to cooperate with each other at a correct timing.
