Explanation
Com port Check
1
Select the com port number of the device.
The com port should be selected each time you start the software.
2
If this device is present in Com port, this menu is disabled.
If not, go back to step 1 again.
View measurement waveform
1
Proceed in the same way as “COM port check”.
2
Identify the direct data and process data (power spectrum, histogram) provided by the device.
3
The current state stops. At this time, com port is closed.
Clicking the Start button reopens the com port.
4
Software shutdown
Saving the Measurement Waveform
1
Proceed in the same way as “COM port check”.
2
Specify folder and file name.
3
The file size increases from the time waveform view starts.
At this time, although the spectrum and the histogram can be seen, the data is not stored.
4
stop. Storage session completed.
You must specify the file again for a new save.
5
Software shutdown.

Table[2]. Procedures for using software.

Waveform storage may or may not be performed depending on whether “file” is specified prior to “start”. Overwriting a file depends on the user’s choice.

 

Viewer S/W Screen description

Viewer software screen configuration for neuroNicle FX2 device.


Figure[18]. neuroNicle FX2 waveform view software screen.

[1]. COM port number : If the software is correctly installed, show all com ports installed on your computer when you start the software. Select the correct number to match the com port of the device.

[2]. COM Check : Check that the com port setting in [1] matches the device. If the neuroNicle FX2 device is found on the com port, this menu will be disabled and the menu [3], [4] will be activated.

[3]. Start : If this button is active, you can check the waveform. When this menu is selected, only [5] stop button is activated.

[4]. File : Select this menu to specify the folder and name of the file to save. Waveform storage is possible only when a new file is specified. If you select an existing file when you specify a new one, you are asked if you want to “overwrite” it. If the user allows “overwrite”, the new waveform data is written to the existing file.

[5]. Stop : It is activated only in the waveform view (click [3] start button). “Stop” closes com port and save file.

[6]. End : Exit the software.

[7]. Firmware information : Displays the firmware ID of neuroNicle FX2.

[8]. Communication path information : Show communication path information used by neuroNicle FX2.

[9]. Status Notification Window : Displays the current operating mode of the software.

[10]. File path : Displays the name and path of the file to be saved. The files are stored in txt format.

[11]. File size : Displays the size (in kB) of the file to be saved in real time.

[12]. Real-time heart rate per minute : Displays the real-time heart rate in bpm.

[13]. Channel 1 electrode connection state : Indicates whether the channel 1 electrode (left forehead electrode) is in contact with the skin. When contacted, it turns green.

[14]. Channel 2 electrode connection : Indicates whether the channel 2 electrode (right forehead electrode) is in contact with the skin. When contacted, it turns green.

[15]. Reference electrode connection status : It indicates whether or not the reference electrode (ear clip electrode) is in contact with the skin. When contacted, it turns green.

[16]. Sensor wearing state : Indicates whether the sensor band is worn on the head. If correctly worn, it is green, otherwise it is red.

[17]. Ear clip electrode state : Check that the electrodes are in contact with each other on the clamp structure with the ground and reference electrodes. If the electrodes are stuck together, they are displayed in green. If it is not in contact, it is displayed in red.

[If the ear clip are stuck together but not stuck, the device is in a broken state.]

[18]. Battery remaining : Displays the remaining battery level (in%). The value changes by 5%. The remaining amount is displayed in yellow, and the lower limit (10%) is indicated in orange. If the current level is below the lower limit, a low battery warning ([19]) occurs. The value can be varied at the boundary value.

[19]. Low battery warning : If the current battery level is less than 10%, a low battery warning occurs and turns red. If a low-battery warning occurs, stop using it and charge the battery.

[20]. Left brain waveform (EEG-CH1) : It shows the EEG detected by the left forehead electrode. The signal size unit is uV. The maximum and minimum values of the graph can be changed by double-clicking the value.

[21]. Right brain waveform (EEG-CH2) : It shows the EEG detected by the right forehead electrode. The signal size unit is uV. The maximum and minimum values of the graph can be changed by double-clicking the value.

[22]. PPG: The PPG detected by the sensor provided on the ear clip electrode is displayed. Automatic gain control (AGC) of the PPG is performed once when the initial sensor is worn. During the measurement, the pulse wave signal can be changed according to the size of the original signal. If the PPG is not measured correctly, remove the ear clip and try again.

[23]. Second Differential PPG (sdPPG): It is the data provided by the device as a pulse waveform obtained by differentiating the PPG by a second time. A heartbeat pulse is detected at the apex of this waveform. The magnitude of this signal varies with the size of the PPG.

[24]. Heartbeat pulse (pulse): It is the heartbeat pulse detected at the apex of the sdPPG signal. This data is from PUD0.bit7.

[25]. Heart rate interval (peak_interval): It is the time interval between heartbeat pulses displayed in msec. This data can be used as raw data for HRV analysis. The accuracy of this value is 4 msec.

[26]. EEG power spectrum : The power spectrum of left and right brain EEG waveforms is shown. This is the power spectrum obtained by FFTing the sampling interval data of 4 msec for 2 seconds of waveform. It is obtained by real-time FFT by pushing single data. The frequency resolution is 0.5 Hz and the maximum frequency is 125 Hz. The frequency value of the horizontal axis can be adjusted by changing the boundary value by double-clicking.

[27]. Heart rate interval histogram : The heart rate interval data of [25] is expressed as a histogram graph. The number of data used is 180, and the class interval is set to 20. At approximately 3 minutes, the first data is excluded from the histogram graph.
