Drowning prevention and soothing device

A method of operating a combination drowning prevention and soothing device, comprising:

• providing a housing having a central processor and a heartbeat sensor, a moisture sensor, a local wireless networking transceiver, an accelerometer, and a memory, wherein the heartbeat sensor, the moisture sensor, the local wireless networking transceiver, the accelerometer, and the memory are each operably coupled to the central processor;
• the central processor determining a present mode of operation, wherein the present mode of operation is one of a drowning prevention mode and a soothing mode;
• when operating in the drowning prevention mode the central processor:
• monitoring the heartbeat sensor and comparing a heartrate of a wearer as detected by the heartbeat sensor to a first preselected heartrate threshold;
• monitoring the moisture sensor to determine whether the moisture sensor indicates the housing is submerged for a preselected time threshold;
• and
• when the heartrate exceeds the first preselected heartrate threshold or when the moisture sensor indicates the housing has been submerged for the preselected time threshold, the central processor causing the local wireless networking transceiver to send an alert signal to a mobile device that is associated with the combination drowning prevention and soothing device;
• when operating in the soothing mode the central processor:
• monitoring the heartbeat sensor and comparing a heartrate of a wearer as detected by the heartbeat sensor to a second preselected heartrate threshold;
• monitoring the accelerometer to determine if an acceleration of the housing over time matches an agitation pattern;
• and
• when the heartrate exceeds the second preselected heartrate threshold or when the accelerometer indicated the acceleration matches the agitation pattern, the central processor selecting an audio file from the memory and providing the audio file to an audio circuit that is operably coupled to the central processor, whereupon the audio circuit plays the audio file over a speaker contained in the housing.
