Abstract: An ultraviolet C (UVC) unit, comprises a Light Emitting Diode (LED) module containing a series of UVC LEDs that provide UVC emission, a lens that linearly focuses the UVC emission of the LED module and a controllable baffle that directs UVC light that passes from the LED module through the lens. The UVC light emitted from the LED module is directed toward the lens for linearly focusing the emission of the LED module in order to propagate the light throughout a top portion of a room in which the UVC unit is positioned, when the baffle is in a first position, and wherein the light is propagated downward from the UVC unit when the baffle is in a second position.

Abstract: Systems, methods and devices for detecting a presence of an analyte in a fluid sample are described herein. The devices include a microfluidic module having a microfluidic channel configured to receive the fluid sample at an inlet thereof and direct the fluid sample towards an outlet thereof. The devices also include an image sensor positioned removably abutting the microfluidic module. The image sensor is positioned laterally between the inlet and the outlet of the microfluidic channel and below a lower surface of the microfluidic channel. The image sensor is communicatively coupled to a processor that is configured to receive signal data from the image sensor. The devices also include a light source configured to direct light through the fluid sample and towards the image sensor as the fluid sample passes through the microfluidic channel. The image sensor receives the light and outputs the signal data to the processor.
