Abstract: A method for increasing the safety of a person in an aquatic environment including attaching a remote node to a monitee, sensing atmospheric pressure; sensing continuously the actual atmospheric pressure of said remote node; communicating bi-directionally with a base station via RF transreceiver; comparing pressures via microcontroller; signaling a monitee when the comparison yields a result that exceeds the pressure set point, thereby providing the monitee with a predetermined time interval to get back into compliance, else notifying the base station via the remote node of the non-compliant pressure reading and duration thereof via visual indicator and vibrating motor; setting the predetermined time interval by the base station; providing the base station with a deployment means for deploying said buoy means; deploying said buoy means by activating a button on the base station; and sending a message repeatedly from the base station to the remote node to activate the buoy.

Abstract: An interactive life system for increasing the safety of person in water having a base station configured to communicate with a remote node; the base station having a first controller having a first microcontroller; and a transceiver means; wherein the base station further includes an alert for alerting a monitor, a pager; a NOAA weather receiver; wherein the remote node comprises a second controller, a second transceiver, a GPS, a buoy, a panic button, a pressure transducer, a visual indicator, a vibrating motor, and a mount; wherein the second controller comprises a second microcontroller; wherein the panic button communicates with the base station; wherein the visual indicator includes light; wherein the vibrating motor includes a mechanical indicator; and where the monitee can wear the device on the wrist.
