Sensors having more than twenty discrete spectral bands are sometimes referred to as hyperspectral imaging sensors. “Natural uranium” (0) means uranium containing the mixtures of isotopes occurring in nature. “Network access controller” (4) means a physical interface to a distributed switching network.
