    Abstract: Disclosed is a method for detecting and/or growing particles, comprising controlling the surface area exposed to the saturator region by monitoring at least one of a depth of the working liquid on the saturator surface, the surface area exposed to the saturator region, or a volume of the working liquid on the saturator surface. Also disclosed is an apparatus or system for detecting and/or growing particles, comprising a fluidics system configured to control the surface area exposed to the saturator region by monitoring at least one of a depth of the working liquid on the saturator surface, the surface area exposed to the saturator region, or a volume of the working liquid on the saturator surface. Certain aspects do not employ one or more porous structures for vapor generation, nor a separate carrier fluid flow or inlet comprising a carrier fluid and vaporized working liquid for combining with the sample flow in the saturator region.

    Abstract: A system for inspecting a fluid includes a lighting system for illuminating a fluid under inspection in an image detection area; an image capture system for capturing a sequence of images of the fluid in the image detection area; a magnetic component for generating a magnetic field towards the image fluid under inspection, the magnetic component having at least one coil for generating a magnetic field, whereby ferromagnetic particles in the fluid under inspection are prevented from reaching the image detection area; wherein the image capture system is configured to capture an image of the fluid in the image detection area before the magnetic field is applied and an image of the fluid in the image detection area after the magnetic field is applied, free of ferromagnetic particles; and a processing component configured to compare the images of the fluid under inspection and count the ferromagnetic particles in the fluid.

    Abstract: A system for determining a vehicle operating state is provided. The system includes at least two particle detectors, a controller and a memory. A sample volume used by each particle detector of the at least two particle detectors configured to be collected in a different location relative to the vehicle than another sample volume used by another particle detector of the at least two particle detectors and at least one sample volume is configured to be collected in an environment where particles are disturbed by the vehicle. The controller is configured to determine at least one operating state of the vehicle based at least in part on a comparison of output signals of the at least two particle detectors. The at least one memory is used to store at least operating instructions implemented by the controller in determining the at least one operating state of the vehicle.

    Abstract: Aspects of the present disclosure include methods for characterizing particles of a sample in a flow stream. Methods according to certain embodiments include generating frequency-encoded fluorescence data from a particle of a sample in a flow stream; and calculating phase-corrected spatial data of the particle by performing a transform of the frequency-encoded fluorescence data with a phase correction component. In certain embodiments, methods include generating an image of the particle in the flow stream based on the phase-corrected spatial data. Systems having a processor with memory operably coupled to the processor having instructions stored thereon, which when executed by the processor, cause the processor to calculate phase-corrected spatial data from frequency-encoded fluorescence data of a particle a flow stream are also described. Integrated circuit devices (e.g., field programmable gate arrays) having programming for practicing the subject methods are also provided.
