    Abstract: A bidirectional AC-to-DC and DC-to-AC circuit includes a first inductor-capacitor (LC) circuit connected to an AC power source, a transistor synchronized with the AC power source signal, a second LC circuit electrically connected to the synchronized transistor and the first inductor-capacitor circuit, a high-frequency switching transistor electrically connected to the second inductor-capacitor circuit and a direct current (DC) load, and a controller connected to the high-frequency switching transistor. The controller identifies an error between a measured DC output signal and a predetermined DC output signal that is applied to the DC load, and adjusts a duty cycle of a pulse width modulation (PWM) switching signal for the high-frequency transistor to reduce the identified error.

    Abstract: In a linear drift tube partitioned into a plurality of cascaded drift tube segments each followed by an ion elimination region, a system and method of separating ions includes repeatedly establishing electric drift fields in the drift tube segments and in some of the ion elimination regions while establishing electric repulsive fields in others of the ion elimination regions such that ions having a predefined mobility or range of mobilities are transmitted through the drift tube in one direction, and when the ions reach the end of the drift tube the electric drift fields are reversed and the process is repeated to transmit the ions to the opposite end of the drift tube. Ions may be made to pass back and forth through the drift tube any number of times before being drawn out of the drift tube to an ion detector or into another drift tube.

    Abstract: A hybrid ion mobility spectrometer includes a single-pass drift tube having an ion inlet at one end and an ion outlet at an opposite end, a multiple-pass drift tube having an ion inlet and an ion outlet each coupled to the single pass drift tube between the ion inlet and the ion outlet thereof, and a set of ion gates each controllable between an open position to pass ions therethrough and a closed position to block ions from passing therethrough. The set of ion gates may be controlled to pass at least some ions traveling through the single-pass drift tube into the multiple-pass drift tube via the ion inlet of the multiple-pass drift tube and to pass at least some ions traveling through the multiple-pass drift tube into the single-pass drift tube via the ion outlet of the multiple-pass drift tube.
