Patent ID: 8854228

Claim:
A computer comprising: a microprocessor; a memory system including an operating system stored therein; a bus system coupling the memory system to the microprocessor; a single point indicator coupled to the microprocessor, wherein the single point indicator is mounted in a location visible to a user, the single point indicator being capable of emitting a single point of light of substantially any wavelength in a visible spectrum; first logic that determines a level of a selected one of a plurality of operational parameters of the computer, wherein the selected one of the plurality of operational parameters varies continuously between a first level and a second level, wherein the first logic is operable to distinguish between at least the first level and the second level, wherein the first and second levels are distinct from each other, and wherein the first and second levels are non-zero; and second logic that generates a corresponding wavelength of light emitted from the single point indicator, wherein the corresponding wavelength of light corresponds to the level of the selected one of the plurality of operational parameters of the computer, wherein the second logic is operable to generate a first wavelength corresponding to the first level and a second wavelength corresponding to the second level, wherein the first and second wavelengths are distinct from each other, and wherein the first and second wavelengths are within the visible spectrum, wherein the first logic-includes logic that determines an average level of the selected one of a plurality of operational parameters of the computer during a selected time interval and wherein the second logic generates the corresponding wavelength of light emitted from the single point indicator for the selected time interval.
