Abstract: A system with a machine and a lighting device. The machine includes an image capture device and a machine vision processing system configured to detect a characteristic of a subject in a space for an operation of the machine. The lighting device includes a first light source for generating light to illuminate the space, and a second light source for generating light of a particular wavelength to support detection of the characteristic of the subject via the machine vision processing system. The light of the particular wavelength is output at a sufficient intensity reasonably expected to produce a particular emission from the subject detectable via the image capture device different from an emission produced by exposure of the subject to the light for illumination of the space. The first and second light sources are integrated into the lighting device.

Abstract: The invention provides a high resolution, wide dynamic range, multi-color detection platform for microfluidic analyzers/instruments and methods. The detection platform uses multiple high gain semiconductor optical sensors for the detection of luminescence from cellular or biological samples. The digitized outputs from these sensors are combined and weighted in a signal processing unit, using pre-determined algorithms for each color, which optimize the resolution in each of these high gain semiconductor optical sensors while extending the dynamic range of the detection platform.

Abstract: A user-wearable device includes a front facing first light detector and a backside optical sensor, which faces the user's skin and includes a light source and a second light detector. The device also includes a skin tone detector and an ultraviolet (UV) exposure detector. The UV exposure detector is adapted to determine estimate(s) of a user's exposure to UV light in dependence on signal(s) produced using the first light detector, calibrate UV exposure threshold(s) in dependence on a skin tone metric produced using the skin tone detector, compare estimate(s) of a user's exposure to UV light to calibrated UV exposure threshold(s), and selectively trigger an alert in dependence on results of the comparison(s). The second light detector is also used to produce a photoplethysmography (PPG) signal from which measures heart rate (HR), heart rate variability (HRV), respiration rate (RR) or respiratory sinus arrhythmia (RSA) is/are produced.
