Abstract
A digital fever thermometer includes a backlit LCD display, which may act as a non-audible annunciator indicating that a stable temperature has been achieved. The digital fever thermometer includes a photo detector and a single mode-select switch to determine when the backlight should be enabled. When the backlight is enabled, the thermometer activates the backlight, indicating that a temperature reading is complete.
