Embodiment Construction
[0038] The present invention preferably includes a compact automatic inflatable floatation device assembly and a detector unit. The detector unit preferably includes at least one physiological sensor that senses a physiological characteristic of an individual, such as a swimming child, being monitored. The detector unit preferably includes a processing and evaluation means for permitting predetermined parameter value(s) to be stored, and means for comparing the output of the at least one physiological sensor with a respective predetermined parameter value, and providing an output signal responsive to that comparison. Preferably, the predetermined parameter value(s) correspond to risk threshold(s) for the particular individual being monitored. The output signal can be used to trigger an local alarm, such as a siren and / or a bank of flashing lights, and / or a remote alarm, and to inflate the floatation device assembly. For example, when a sensor for pulse rate is employed, when the mon...
