I believe that there is a large MARKET for a wearable device (either wrist or necklace) that provides a blue tooth connection to the cell phone and the cell phone would automatically dial 911 directly. It should contain a microphone and speaker to allow conversation with the 911 operator. Obviously must be waterproof. It must also contain safeguards to prevent accidental activation. The number to be dialed should be programmed in the cellphone so that the device could alternately be programed to auto dial any number.This device would save dollars by eliminating the need for paid membership in the medical alert monitoring market whose sole reason for being is to answer ones call and THEN dial 911.
