Claim 12:
13. 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 sounds 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;
a first audio sensor;
a first audio detection circuitry operably coupled with the first audio sensor, the first audio detection circuitry configured to detect audio sounds from the AED via the first audio sensor;
a second audio sensor;
a second audio detection circuitry operably coupled with the second audio sensor, the second audio detection circuitry configured to detect the audio sounds from the AED via the second audio sensor; and
at least one processor operably coupled with the communications module, the first audio detection circuitry, and the second audio detection circuitry, the at least one processor configured to:
power on the first audio detection circuitry during a periodic detection interval to detect the audio sounds during the periodic detection interval,
process signals from the first audio detection circuitry and generate a wakeup notification signal in response to the detected audio sounds during the periodic detection interval,
activate the second audio detection circuitry to commence an active listening mode in response to the generated wakeup notification signal,
process signals from the second audio detection circuitry during the active listening mode to make a determination that the AED is in need of service, and
transmit a report signal to the monitoring service based on the determination that the AED is in need of service.
