Abstract
Battery powered systems with long standby times, such as automatic external defibrillators (AEDs), may be required to indicate their operational status to a user by blinking lights or sounding speakers or buzzers. These active status indication activities consume power thereby reducing the battery life of the system. To conserve power and to be more effective in seeking attention from a human operator, the status alerts for the AED produced by an active status indicator (ASI) system can be more meaningful to humans or more unique relative to status alerts provided by conventional devices. Additionally, the ASI system may automatically adjust power consumed by the indicators in response to sensing environmental conditions of the AED.
