Wearable computing device for secure control of physiological sensors and medical devices, with secure storage of medical records, and bioimpedance biometric. U.S. Patent 9,595,187; International Patent Application WO2013096954A1, March 14, 2017. Priority date 2011-12-23; Filed 2012-12-24; Issued 2017-03-14. Later revised as kotz:patent9936877.
A wearable master electronic device (Amulet) has a processor with memory, the processor coupled to a body-area network (BAN) radio and uplink radio. The device has firmware for BAN communications with wearable nodes to receive data, and in an embodiment, send configuration data. The device has firmware for using the uplink radio to download apps and configurations, and upload data to a server. An embodiment has accelerometers in Amulet and wearable node, and firmware for using accelerometer readings to determine if node and Amulet are worn by the same subject. Other embodiments use pulse sensors or microphones in the Amulet and node to both identify a subject and verify the Amulet and node are worn by the same subject. Another embodiment uses a bioimpedance sensor to identify the subject. The wearable node may be an insulin pump, chemotherapy pump, TENS unit, cardiac monitor, or other device.
