A signal analysis system for monitoring biological media and analyzing motion-induced signal modulation

摘要

According to one configuration, the system includes sensor hardware and signal processor resources for monitoring and analyzing a subject's biological medium (such as blood and / or other substances). In operation, the sensor hardware monitors the subject's biological medium and generates an output. The monitored output (such as one or more signals) changes based at least in part on the movement induced by the person. The signal processor resource analyzes the output generated by the sensor hardware. Based on the analysis and the detected change in sensor hardware output caused by the movement of the person, the signal processor resource generates a set value for the biometric parameter of interest associated with monitoring the biological medium. It should be noted that the systems described herein can be used to measure different biometric parameters of interest such as venous blood oxygen content, vascular hardness, etc.
