MOTION SENSING IN A WIRELESS RF NETWORK

摘要

Techniques and systems that monitor motion of a person or object and wirelessly communicate the motion data of the person through a network of wireless communication transceiver nodes to a central monitor station. An abnormal state of motion of the person or object can be detected based on the motion data and an alert signal can be generated when an abnormal condition of the person or object occurs. Other parameters of a person or object may also be measured and transmitted to the central monitor station, such as the heart beat and body temperature of the person or the orientation or dynamic motion of an object.
