Abstract: Embodiments in the disclosure are directed to the use of distributed computing to align reads against multiple portions of a reference dataset. Aligned portions of the reference dataset that correspond with an above-threshold alignment score can be assessed for the presence of sparse indicators that can be categorized and used to influence a determination of a state transition likelihood. Various tasks associated with the processing of reads (e.g., alignment, sparse indicator detection, and/or determination of a state transition likelihood) may be able to take advantage of parallel processing and can be distributed among the machines while considering the resource utilization of those machines. Different load-balancing mechanisms can be employed in order to achieve even resource utilization across the machines, and in some cases may involve assessing various processing characteristics that reflect a predicted resource expenditure and/or time profile for each task to be processed by a machine.

Abstract: A method for recording pulse signals which allows the reconstruction of a time reference. The time of every pulse signal event can be determined by counting sampling result bits preceding the respective sampling result bit using the known sampling frequency. For this purpose, every period of the sampling frequency is associated with a bit representing the respective sampling result and the sampling result bits are stored one by one and per channel in data blocks. The sampling frequency is preferably higher than a pixel clock, a sampling result bit associated with a flank of the pixel clock being marked. The pixel clock can thus be synchronized with the individual events exactly per sampling period. The invention further relates to the field of fluorescence correlation spectroscopy using confocal microscopes or laser scanning microscopes.

Abstract: A data analysis technique for a long data record in a memory uses a reference, either user-provided or calculated from the data in the long data record, as a representative event. Each event in the long data record is compared with the reference to determine whether there are significant deviations from the reference.

A tolerance value may be added to the waveform reference and varied for dynamic limit testing. Events that are outside the waveform reference as modified by the tolerance value are identified as outliers and may be reduced to iconic images for display simultaneously with the long data record and a selected one of the outliers.

Abstract: Delay induced apparent amplitude desensitization in a data signal channel and its accompanying worm-like distortion in an Eye Diagram Analyzer is avoided by altering the measurement to avoid the need for any substantial delay in the path of the data channel threshold comparison signals. In a first technique, only enough delay will be inserted in the data channels to produce the relative adjustments needed to compensate for skew between the data channels, as determined by a calibration operation, and it is these de-skewed, but otherwise un-delayed, data threshold comparison signals that are, in rapid succession, clocked into the latches whose difference registers a hit at a given (time, voltage) pair. The clock path delay is then varied from a minimal value to a sufficiently large value capable of spanning a desired the number of eye diagram cycles.
