Abstract: A non-wearable Personal Emergency Response System (PERS) architecture is provided, having a synthetic aperture antenna based RF interferometer followed by two-stage human state classifier and abnormal states pattern recognition. In addition, it contains a communication sub-system to communicate with the remote operator and centralized system for multiple users' data analysis. The system is trained to learn the person's body features as well as the home environment. The decision process is carried out based on the instantaneous human state (Local Decision) followed by abnormal states patterns recognition (Global decision). The system global decision (emergency alert) is communicated to the operator through the communication system and two-ways communication is enabled between the monitored person and the remote operator. In some embodiments, a centralized system (cloud) receives data from distributed PERS systems to perform further analysis and upgrading the systems with updated database (codebooks).
