Abstract: A nonmechanical fully electronic multifunctional digital indicator useful for providing elapsed time indications or as event counters is disclosed. The event counter uses a ChLCD-type matrix array and requires unique steps to properly erase and place new information on the display without inadvertently changing the status of individual array elements.

Abstract: A dimmable, infrared secure, indicator for use in equipment panel displays capable of maintaining sufficient luminance for proper equipment operation by personnel in covert situations, while minimizing detection by hostile entities is realized by a device comprising an light source, an infrared absorbing filter, and two polarizers. These components are incorporated into an external housing which includes a selectively rotatable segment capable of rotating one of the polarizers from a fully parallel to fully crossed position with respect to the other and a hood which minimizes the viewing angle of the indicator.
