Since there is said to be no computer hooked up, the storage device is maybe a flash memory. they come in gigabyte size now for less than a 100 bucks. The power supply? I see no plug in wires in the pictures, so probably re-chargeable batteries.
I dunno how much a UVF spectrometer costs, I ain't got wunna them.
Yeah, they ain't any money in this gadget. BAXA can add it to the sales portfolio, and maybe sell a few copies. Or get somebody else to make it for them, or simply build them for themselves if they sell.
CDEX has no patent, and not much money with which to file suit.
