Abstract
A system synchronizes a PC exhibiting latency of operations to a biosensor enabled microcontroller with real-time clock by providing an encoding scheme that captures the subject's absolute reaction time transmits the subject's reaction time from the PC exhibiting latency to the microcontroller with real-time clock. The system includes a transmitter that transmits a stimulus signal from the PC exhibiting latency, an input device indicating the subject's response to the stimulus signal, an encoding circuit adapted to encode a difference in time between the stimulus signal and the subject's response to the stimulus signal, an emitter adapted to transmit the encoded difference signal representing the subject's reaction time, and a complementary receiver adapted to detect the encoded difference signal. The receiver includes a decoding circuit that decodes the encoded difference signal to determine the subject's reaction time, and the receiver provides the subject's reaction time to the microcontroller with real-time clock for synchronization with received biosensor data such as EEG data.
