• SPECTROPHOTOMETRY: ChromaID scanner challenges traditional spectrophotometry - Laser Focus World

  • eliminates the need for delicate optical components and expensive detectors by using a “virtual” light-emitting diode (LED) source and inexpensive photodiode detectors
  • the current supplied to the LEDs is varied through a sequence of steps to vary the frequency of the light produced by the emitter
  • one prototype source incorporates 34 emitters that are fired through 25 current steps in a sequence that is repeated four times; in effect, a single less-than-one-second scan paints 34 × 25 × 4 = 3400 flashes of light onto the sample
  • Recent testing on plastic sample bags containing a variety of similar-looking white powders demonstrated that the SPM ChromaID method was able to distinguish between flea powder, household cleaner, ground Tums, Splenda, baby powder, and cornstarch, to name a few

• CES 2013: The Four-Sentence Summary - Forbes

  • With enough of the right sensors in my life, the sensors can flexibly identify the things in my environment and provide a very efficient means of addressing them

• Intellicig-maker CN Creative acquired by Footsie giant British American Tobacco | Manchester Evening News - menmedia.co.uk

  • the acquisition was a natural extension of its approach to tobacco harm reduction
