US10749557B1	Adaptive spur processing A system and method for adaptive spurious signal (spur) processing at a broadband RF receiver. Spur processing addresses the detection of spurs generated by the receiver when high level RF signals are present at its input. The spurs can lead to undesired false detections. Based on signal parameters of the received RF signal, the system detects a strong enough real signal that would cause a spur and prevent generation of false reports. The adaptive spur mitigation scheme uses multiple detection and report thresholds to enable false report rejection with an improved high probability of rejecting false detections, while minimizing the adverse effects on multi-tone dynamic range. The necessary detection and report thresholds are generated based on a system level behavioral model that predicts the performance of several different types of spurs as a function of signal parameters. The thresholds are tuned to match the behavior of the dominant spur.

The perturbation W may be introduced in various ways, such as by distorting the geometry of the trap so that it no longer follows an equipotential of the ideal field U(r, ϕ, z), or by adding a distortion field (either electric or magnetic). The magnitude of the perturbation is such that at least some of the trapped ions have an absolute phase spread of more than zero but less than 2π radians over an ion detection period Tm.
US10748754B2	Isotope mass spectrometer An isotope mass spectrometer including: an electron cyclotron resonance ion source, a front-end analysis device, a back-end analysis device and an ion detector; where the electron cyclotron resonance ion source is connected with the front-end analysis device, and is used for generating ion beams of multivalent charge states; the front-end analysis device is connected with the back-end analysis device, selects and separates the ion beams, and receives ion beams of constant, microscale and trace levels; the back-end analysis device is connected with the ion detector, and is used for eliminating a background of an isotope to be measured at an ultratrace level; and the ion detector is used for receiving ion beams of the ultratrace level, and carrying out energy measurement and separation on the ion beams of the ultratrace level, so as to obtain the isotope to be measured at the ultratrace level.
US10748752B2	Data independent acquisition with variable multiplexing degree A method is disclosed for analyzing ions by mass spectrometry by repeatedly executing a data acquisition cycle to acquire product ion data across a precursor mass range of interest. The data acquisition cycle comprises performing, for each of a plurality of isolation windows having different mass ranges, steps of (i) isolating precursor ions within the mass range of the isolation window, (ii) fragmenting the isolated precursor ions to generate product ions, and (iii) mass analyzing the product ions. The step of mass analyzing the product ions includes concurrently mass analyzing product ions corresponding to N isolation windows, N being an integer greater than or equal to one, wherein N is changed at least once across the data acquisition cycle.
