Emergency alarm system: prototype and experience

Finding fusion in the domain of engineering and healthcare, we propose a wearable emergency alarm system that 1) monitors continuously the activity levels of the patient and 2) detects anomalies, in particular unconsciousness, in a timely fashion to alert the caregivers of the emergencies. In this summary, we share our experience building the first prototype and the preliminary results that support the feasibility of the system and give rise to a number of design choices towards better energy efficiency and emergency event detection accuracy.
