Abstract: Systems and methods are provided for characterizing shuttle capture events in a nanopore sensor. The method first collects time-dependent current blockage signatures for at least one bias voltage. The method then identifies each signature as corresponding to a permanent or transient event. The method then generates a protein dynamics landscape (PDL) for the transient event signatures. The PDL comprises a set of histograms of nanopore current data and characterizes current through the nanopore during shuttle capture events. The method can then comprise identifying an entrance level blockage value based on the permanent event signatures. Permanent event captures can be determined by time duration which is larger than a certain threshold time value. Applying a between the fluidic chambers above a threshold voltage level can be used to control that the vast majority of events are permanent.

Abstract: Modern X-ray generators are required to deliver a peak power between 30 kW and 120 kW. This requirement places demanding constraints on the design of the power inverters used to supply such X-ray generators, at the same time that there exist industry incentives to reduce the size of X-ray generators. An trend towards increased frequencies of switching operation in the power stage of modern X-ray generators makes it possible to use air-core inductors, rather than magnetic-core inductors. This application discusses an air-core inductor assembly having an integral current sensor. According to this application, a current sensor can be more accurately provided, which does not drift in position over time, and in a way which reduces the overall bill of materials.
