In one embodiment, the present invention provides for extended memory protection for memory of a system. The luminous layer includes: a luminescent dopant having a reorganization energy of 0 eV to 0. Blood analyte concentrations are then estimated using support vector regression analysis. The level shifting mechanism adjusts the common mode voltage by either drawing a level shifting current from the output node and the complementary output node or injecting a level shifting current into the output node and the complementary output node. The optical characteristics of the particles are determined on the basis of the direct backscattering signal and the counterpropagating backscattering signal. In order to minimize occurrences of a user viewing information about a first patient and images of a second patient, and mistakenly believing the information and images belong to the same patient, a visual indicator may be displayed over images that are out-of-context with the information displayed.
