Abstract: The method and apparatus of the present invention provides a system wherein light-emitting diodes (LEDs) (162) can be tuned within a given range by selecting their operating drive current in order to obtain a precise wavelength. The present invention further provides a manner in which to calibrate and utilize an LED probe (150), such that the shift in wavelength for a known change in drive current is a known quantity. In general, the principle of wavelength shift for current drive changes for LEDs is utilized in order to allow better calibration and added flexibility in the use of LED sensors, particularly in applications when the precise wavelength is needed in order to obtain accurate measurements. The present invention also provides a system in which it is not necessary to know precise wavelengths of LEDs where precise wavelengths were needed in the past. Finally, the present invention provides a method and apparatus for determining the operating wavelength of a light-emitting element such a light-emitting diode.

Abstract: A light detection module has N optical channels, each with an optical filter, a detector, and an amplifier; and an N×1 switch with N input ports each connected to one corresponding output port of each channel to receive an amplified detector output corresponding to a filtered optical intensity incident on that detector. The switch cycles between channels, connecting each amplified detector output in turn to the output port. An ADC samples a time dependent optical intensity signal from the switch, generating a corresponding ADC digital signal output. A microcontroller, connected to the N×1 switch and the ADC, controls acquisition by the ADC to provide a digital voltage data stream from each channel; making the average optical intensity value characterizing the voltage data stream available from each channel at a digital output port of the microcontroller, as N data values, characterizing the light incident on the N channels of the module.

Abstract: In some implementations, a device may identify, based on spectroscopic data, a pseudo steady state end point indicating an end of a pseudo steady state associated with the blending process. The device may identify a reference block and a test block from the spectroscopic data based on the pseudo steady state end point. The device may generate a raw detection signal associated with the reference block and a raw detection signal associated with the test block. The device may generate a statistical detection signal based on the raw detection signal associated with the reference block and the raw detection signal associated with the test block. The device may determine whether the blending process has reached a steady state based on the statistical detection signal.
