Claim 22:
23. A remote monitoring device for monitoring audio signals from an automated external defibrillator (AED) and electronically reporting to a monitoring service via a communications network, comprising:
a housing configured to be positioned outside of the AED such that audio signals from the AED can be detected, the housing containing:
a communications module configured to transmit electronic communications to the monitoring service via the communications network;
at least one audio sensor;
at least one audio detection circuitry operably coupled with the at least one audio sensor, the at least one audio detection circuitry configured to detect audio sounds from the AED via the at least one audio sensor; and
at least one processor operably coupled with the communications module and the at least one audio detection circuitry, the at least one processor configured to:
process signals from the at least one audio detection circuitry based on the detected audio sounds,
detect a first audio signal from the processed signals,
in response to the first audio signal being detected, commence an active listening mode to detect a second audio signal from the processed signals and confirm that the second audio signal meets a predetermined criterion associated with the active listening mode;
in response to the second audio signal being detected, re-commence the active listening mode to detect a third audio signal from the processed signals and confirm that the third audio signal meets the predetermined criterion associated with the active listening mode, and
transmit a report signal to the monitoring service if the third audio signal meets the predetermined criterion.
