Abstract

The design of a 20-segment LED display device is presented. The display visually indicates peak levels of slowly changing biomedical data. Its fullscale indication is adjustable from +0.5 to +12.5 volts. The segments can be activated in either a dot or a bar mode, and upper-limit sensing can be indicated by an audio tone and/or a flashing display.
