Abstract: System that enables urine testing in a home environment. A user may apply a urine sample to a card containing multiple tests, and capture an image of the card using a phone; an analysis system executing on the phone or in the cloud may analyze the image and determine test results. The test card and analysis system may compensate for variability in lighting conditions and time of exposure to the urine sample, which are difficult to control in a home environment. The test card may contain fiducial markers of known colors; the analysis system may adjust colors in the captured image based on appearance of these markers. Color adjustments may also compensate for nonuniform lighting across the card. The card may also contain time indicators that change appearance over time after urine is applied, and the analysis system may use these indicators to calculate the time of exposure.

Abstract: Spectral irradiance distributions are calculated within a virtual environment based on arbitrary light source spectral power distributions. Architectural, horticultural and aquacultural lighting control systems use the calculated results to control both the intensity and spectral power distribution of the electric light sources. Energy consumption may be minimized while maintaining optimal occupant visual comfort and plant health.
