Abstract: A covert information viewing system converts visible light to infrared wavelengths that can be transmitted for detection by an infrared-sensitive detector, such as night vision goggles, without detection by the human eye. The system includes a visible light information source emitting radiation as visible light, and a covert covering including an energy converting layer for absorbing the visible light emitted from the visible light information source and converting the visible light to infrared wavelengths, and a light blocking layer capable of absorbing unconverted visible light and transmitting infrared wavelengths. The covert covering is attached to the visible light information source and oriented to cover visible light emitted from the visible light information source, but it is also easily removed from the visible light information source.

Abstract: The present disclosure relates to aerosol delivery devices that may include components configured to convert electrical energy to heat and atomize an aerosol precursor composition. An outer body may at least partially enclose the components. An illumination source may be configured to output electromagnetic radiation. For example, a light emitting diode may output light.
