    Abstract: Embodiments are directed to an apparatus that includes a fluidic structure and optical components. The fluidic structure includes a transparent channel through which objects in an analyte fluid can travel along respective paths during operation of the apparatus. The optical components are configured to provide measurement light to the objects traveling through the transparent channel. The fluidic structure is configured to reversibly engage with a host structure. The host structure includes a source of the measurement light and electronics to receive and process output light emanating from the objects traveling in the channel. The fluidic structure makes an air-tight seal when engaged with the host structure.

    Abstract: A monitoring system for a power grid includes one or more power transformer monitors. Each power transformer monitor includes a plurality of optical sensors disposed on one or more optical fibers that sense parameters of the power transformer. Each optical sensor is configured to sense a power transformer parameter that is different from a power transformer parameter sensed by at least one other sensor of the plurality of optical sensors. An optical coupler spatially disperses optical signals from the optical sensors according to wavelength. A detector unit converts optical signals of the optical sensors to electrical signals representative of the sensed power transformer parameters.

    Abstract: Approaches for determining the delivery success of a particle, such as a drug particle, are disclosed. A system for monitoring delivery of particles to biological tissue includes a volume, an optical component, a detector, and an analyzer. The volume comprises a space through which a particle can pass in a desired direction. The optical component is configured to provide a measurement light. The detector is positioned to detect light emanating from the particle in response to the measurement light. The detected light is modulated as the particle moves along a detection axis. The detector is configured to generate a time-varying signal in response to the detected light. The analyzer is configured to receive the time-varying signal and determine a delivery success of the particle into a biological tissue based upon characteristics of the time-varying signal.

    Abstract: Approaches for determining object position in a flow path are disclosed. A system includes a spatial filter having a length disposed along a longitudinal axis of the flow path and a width along a lateral axis of the flow path. The spatial filter has mask features configured to modulate light. Light emanating from objects moving along the flow path is detected. The detected light has a component along a detection axis that makes a non-zero angle with respect to the longitudinal and lateral axes. An electrical output signal that includes information about the trajectory depth of the object is generated in response to the detected light.
