Abstract
An individual activity monitoring system comprises a microphone configured to receive sounds and convert them to audio signals, a memory configured to store recorded audio signal patterns of water flow events, and a microprocessor coupled to the microphone and configured to receive the audio signals, compare the audio signals to the recorded audio signal patterns, and recognize whether the audio signals represent a water flow event. The microprocessor is configured to reset a reset clock in response to a recognized water flow event, and being further configured to issue an alert notification in response to an absence of a subsequent water flow event after the reset clock exceeds a preprogrammed time period since a last recognized water flow event.
