Neuro-physiological Optical Sensor Suite for Gravity-Induced Loss of Consciousness Monitoring and Intervention

Real-time monitoring of the physiological state of pilots flying high performance tactical aircraft would offer significant benefits to the prediction and detection of gravity-induced loss of consciousness (GLOC) and almost loss of consciousness (ALOC) and thus help prevent aviation mishaps and loss of lives and aircraft. Such measurements are typically difficult to accomplish because the sensor technologies currently available are hard to attach to and remove from human subjects. However, it is of increasing importance that miniature, compact, reliable and rugged sensor technologies be developed to monitor the neuro-physiological response of the brain in stressful operational environments, including the tactical cockpit, if significant performance and safety improvements are to be achieved. This proposal addresses development of a real-time neuro-physiological optical sensor suite for the prediction and detection of gravity induced loss of consciousness (GLOC), and almost loss of consciousness (ALOC). An all-optical sensor that combines Near Infrared Spectroscopy (NIRS) and optical electrodes (PhotrodeT) would provide a reliable device that could be integrated with a flight helmet. The sensing system would be suitable for integration with tactical aircraft cockpit and control systems to provide a reliable means to rapidly detect the onset of GLOC, provide alert/alarm functions and an autopilot recovery mechanism.
