    Abstract: An input driven self-clocked dynamic comparator, and associated systems and methods are described herein. In one embodiment, self-clocked dynamic comparator, includes a latch configured to receive an input voltage (VIN), a reference voltage (VREF) and a clocking (CLKsf) signal, and configured to output a first rail-to-rail output (OUT+) signal and a second rail-to-rail output (OUT−) signal. The self-clocked dynamic comparator also includes a pre-amplifier (PRE-AMP) configured to output an enable (TRI) signal based on a comparison between the VIN and an adjusted VREF. The self-clocked dynamic comparator further includes a pre-amplifier (PRE-AMP) configured to output an enable (TRI) signal based on a comparison between the VIN and an adjusted VREF, and a logic gate configured to receive the TRI signal and one of the OUT+ signal and OUT− signal, and configured to output the CLKsf signal. The cycles of the CLKsf signal cause the latch to dissipate energy.

    Abstract: Systems and methods for analyzing particles flowing in a channel are described. In an embodiment, the channel is configured to flow a particle through a lumen of the channel, the channel defining an interrogation window configured to allow light to pass into and out of the lumen; a light engine comprising: a first light source positioned to output first excitation light onto a first portion of the channel in the interrogation window; and a second light source positioned to output second excitation light onto a second portion of the channel in the interrogation window separate from the first portion. In an embodiment, the systems include an emission fiber bundle comprising a first emission optical fiber and a second emission optical fiber, wherein a proximal end of first emission optical fiber and second emission optical fiber are arranged in an emission fiber bundle head.

    Abstract: Systems and methods for optical computation and acousto-optic modulation are described. The systems and methods comprise acousto-optic modulators with reflectors and transducers used for actuation and modulation of mechanical waves. The systems further comprise multilayer optical computing systems incorporating arrays of acousto-optic modulators. In an embodiment, the acousto-optic modulator comprises a substrate; an optical layer coupled to a first portion of the substrate, the optical layer comprising: a free-standing portion shaped and positioned to define a gap between the free-standing portion of the optical layer and the substrate; and a rib waveguide comprising a photonic crystal, formed in the free-standing portion; and a piezoelectric transducer mechanically coupled to the free-standing portion, wherein the piezoelectric transducer comprises a piezoelectric material and a plurality of conductive electrodes disposed in electrically conductive contact with the piezoelectric material, the plurality of conductive electrodes extending from a base portion of the piezoelectric transducer.

    Abstract: A reactor system includes a first reaction chamber, a second reaction chamber, a resource, one or more processors, and a computer readable medium storing instructions that, when executed by the one or more processors, cause the one or more processors to perform functions. The functions include making a first determination that providing a first reaction chamber access to a resource of a reactor system requires that the first reaction chamber have exclusive access to the resource. The resource includes a reactant source and/or a vacuum pump. The functions also include making a second determination that a second reaction chamber does not require access to the resource. The functions also includes providing the first reaction chamber exclusive access to the resource in response to making the second determination.
