Abstract: A method and system for providing pulsed power and data from a main control unit to slave units via a first bus. The main control unit has an AC signal generator for providing a plurality of first pulses (P1) on the bus for providing the power to the slave units. Each slave unit is AC-coupled to the bus via a first series capacitor arranged for converting the first pulses (P1) into second pulses (P2). Data communication from the main control unit to the slave units is established by modulating the first pulses (P1), and by demodulating the second pulses (P2). The modulation may be based on Pulse Position Modulation, Pulse Width Modulation, Pulse Count Modulation, Pulse Amplitude modulation. Zero, one or more bits may be communicated per first pulse. Optionally the slave units may communicate to the main control unit via a second bus.

Abstract: The current invention concerns a method for identifying the elemental composition of and/or quantifying the presence of mono-isotopic elements in a molecule in a sample by computing a solution of a system of linear equations ??Ei?n?=Fi, whereby the set of numbers Fi comprises said set of relative peak heights from the aggregated isotopic distribution and the coefficients Ei? of said linear system comprise powers and/or power sums of roots r?,i?. The present invention also provides a method for analyzing at least part of an isotopic distribution of a sample, comprising obtaining data comprising at least one probability qj with which a j'th aggregated isotopic variant of said molecule with mass number Aj occurs within said aggregated isotopic distribution; and computing a probability qi with which an i'th aggregated isotopic variant occurs within said aggregated isotopic distribution, by taking a linear combination of said at least one probability qj.
