METHOD AND DEVICE FOR DISPLAYING DATA AND INDICATOR UNIT POINTING TO IT Russian patent published in 2002 - IPC

FIELD: survival engineering. SUBSTANCE: method involves changing color of self-luminescent part of indicator unit depending on time without visually perceptible jumps or changing at least one of boundary colors within the range of which indicator information field color is changed with preset frequency changing in time and/or space. Timer device switches on liquid crystal screen, multicolor or full-color light- emitting diode which crystal currents depend on time or it is provided with light source and color filter of variable chromaticity. The color filter is positioned behind the screen. The light source is positioned behind the color filter. The screen has property of independently changing transparency of some of regions depending on time causing perceptible light color to change when passing through the screen. The indicator unit has various crystals. Its output surface is manufactured so that it has different radii of curvature in meridian and sagittal cross-sections. EFFECT: reduced stress loads acting upon a patient. 38 cl
