Abstract: An exemplary system to provide visible lighting of a selectable spectral characteristic (e.g. a selectable color combination of light) uses an optical integrating cavity or other diffuse mixing element to combine light of different colors from different color LEDs. Amplitude modulation of pulsed operation the light sources, e.g. pulse amplitude modulation added to a baseline forward bias current for each of the LEDs, controls the amount of each light color supplied to the diffuse mixing element and thus the amount included in the combined light output of the system. A color sensor may provide feedback as to a color characteristic of the combined light, for closed-loop control of one or more of the pulse amplitude modulations. Examples are also disclosed that utilize phosphor doping of one or more of the system's reflective elements, to add desired wavelengths of light to the combined output.

Abstract: An individualized modeling equation for predicting a patient's blood glucose values is generated as a function of non-invasive spectral scans of a body part and an analysis of blood samples from the patient, and is stored on a central computer. The central computer predicts a blood glucose value for the patient as a function of the individualized modeling equation and a non-invasive spectral scan generated by a remote spectral device. If the spectral scan falls within the range of the modeling equation, the predicted blood glucose level is output to the patient. If the spectral scan falls outside the range of the modeling equation, regeneration of the model is required, and the patient takes a number of noninvasive scans and an invasive blood glucose level determination. The computer regenerates the individualized modeling equation as a function of the set of spectral scans and corresponding blood glucose values.
