2.4 Device Operation Diagram of CAI
CAI acts as charging and execution.
When u-USB power is plugged into CAIx, it acts as charging mode. In the charging mode, CAIx
continuously monitors the USB connection. Charging status is displayed with 4 White LEDs on
CAIx. The connected USB can be maintained even after completion of charging, but it is
recommended to disconnect USB if possible.
In the monitoring preparation mode, contact of sensor to human body is monitored
continuously to check access condition to EEG & EMG monitoring execution mode. Unless the
sensor is disconnected, the device acts in this mode until the battery is exhausted. To block
power to the board, it will be turned off automatically when the sensor is disconnected from
the connector.
The EEG & EMG Monitoring execution mode is a mode to act only when all electrodes of CAIs
contact human body and their installation state is confirmed. In this mode, CAIx provides
brainwave poser spectrum values by bands (theta, alpha, L-beta, M-beta, H-beta, and gamma).
Electromyogram (EMG) signal, which is measured between CH1 and REF electrode to detect
muscular movement (forehead frowning) of subject.
Likewise in the monitoring preparation mode, the execution method will be maintained until
continuously monitors the USB connection. Charging status is displayed with 4 White LEDs on
CAIx. The connected USB can be maintained even after completion of charging, but it is
recommended to disconnect USB if possible.
