 Worked on and implemented real-time physiological status monitoring system (RT-PSM) named OBAN (Open Body Area Network) that collects data from COTS (commercial off the shelf sensors) and custom sensors for heart rate, and static load. This data is used to calculate the subjects Physiological Strain Index (PSI) which is an indication of susceptibility to heat injury. Sensor data is transmitted via a Bluetooth Mate Gold modem (ships with RN-41 Class 1 Bluetooth Module) which acts as a serial RX/TX pipeline to a control unit Hub i.e. Seeeduino (Arduino based MCU off of Atmel’s 2560 with built-in Android Development Kit (ADK) support) and forwarded to an Android Smart Phone (Samsung Galaxy Nexus running Android 4.0 Ice Cream Sandwich) or Tablet Display. Android Smart Phone or Tablet Display UI is written in Java using Eclipse and Android Development Tool (ADT) plugin for Eclipse, Hub Control unit interface is written in Visual C++ Worked on and implemented Physiological Status Monitoring emulator (Hub, Mote, Sensor, and Display) in java for testing while hardware was being designed and built Worked on and implemented Android Phone emulator to communicate with Physiological Status Monitoring emulator for testing and debugging while hardware was being designed and built Ported Hub Control Unit code and Messaging Library written in Visual C++ from Ubuntu Linux to Microsoft Windows 7 Professional Enterprise
