NGC
New Generation Computer

A long-term project
Since 2019, we have been working on developing electronics designed to replace the Monox PpO2 display, initially as a display. We also intend to upgrade this display to a dive computer that manages decompression.
To integrate this new electronics into the TRITON®, the latter has undergone its CE certification, which also includes electromagnetic testing.


The central unit

The main unit is the cell housing. It incorporates the main board of the NGC’ electronics on which there is the emergency pressure sensor, the whole being sealed in resin. It contains the intelligence and the electronics’ black box.
The main unit is made of the following components:
-
The inner clip of the cells holder allow to maintain in place all components of the cells holder in an easy way.
-
The Humidy pad, captures the surrounding humidity close to the cells.
-
The cell holder plate holds in place the cells inside the cells holder.
-
The Main board, the Main
-
The secondary pressure sensor, connected to the Main Board and sealed in resin.
-
The central unit box, contains all these elements and protect them during transportation or when the are integrated in the rebreather.
-
The cells are connected by a Molex plug. The set up of the cells is more robust if done without cables to prevent these from premature aging.
-
The Main Sup PCB enables to easily connect the 3 cells. This plate has the first pression sensor.
The display
Control and configuration box for the entire NGC. It is worn on the arm (right or left).
It features a color screen, a vibrator, and two buttons integrated into the box (up, down, and confirm).
The NGC is switched on by simultaneously pressing the 2 buttons of the display.
The menu is called by simultaneously pressing the 2 buttons of the display.
The navigation in the menu is done by pressing one of the button of the display :
-
Top one to go up,
-
Bottom one to go down.

One press corresponds to the move of one line in the drop down list or a digit in the numerical list. To validate, press the 2 buttons of the display simultaneously. The display can be worn on either the left arm or right arm.

A color theme
The display is the control and configuration unit of the entire NGC. This unit is the human-machine interface (HMI). It enables the start up, navigation and setting of all the parameters of the entire NGC. It has a color screen, a vibrator and 2 buttons integrated in the unit.The display is linked to the intermediate module with a cable.
The display setting allows a switch to a low visibility theme, with possible adjustment of the light intensity.

A low visibility theme

The HUD - Head Up Display
The HUD is attached to the breathing loop using the HUD holder either on the right or on the left side of the DSV.

The HUD allows multi-directional visualization of NGC information using 6 LEDs of 3 different colors:
-
The red LED : means a low or very low PpO2
-
The yellow LED : means a high or very high PpO2
-
The white LED : means a non PpO2 alarm (lime time, battery, faulty sensor…)
These LED are placed back to back so that they can be seen by both the diver and his buddy. The message is multidirectional.
When the PpO2 remains in the programmed range, the 2 colors red and yellow flash at the same time every 4, 8, 12 or 16 seconds.


The battery module
The NGC is powered by 2 Li-Ion 18650 type batteries (B1 and B2). They provide a 35 hours autonomy per battery
The way the batteries are managed allows the use of one battery and then the other. Indeed, if the battery B1 is too weak, the switch to battery B2 is immediate. The B2 battery acts as redundancy.
Each battery has its own watertight compartment that can be sealed by screwing waterproof plugs (2 in total). Each compartment is independent from the other thus allowing the replacement of the 2 batteries in an independent way.


It can do all that...
...and so much more
It shows the status of the connection
It provides information on the eGB (NEPTUN solenoid module) connection status via a green or orange indicator.
It also displays the eGB's battery capacity status via a percentage and voltage.

It manages the solenoid


It allows the solenoid to be controlled according to the different PpO2 management modes. Enter your high and low SetPoint values. Switch from one mode to another before or during the dive, it adapts to your desires
It has its internal diving logbook
The NGC has its own diving logbook. The log lists your completed dives in date and time order. The logbook provides a summary of the details of the selected dive and a graph of the dive.



It handles the decompression
Currently in testing, the NGC will support decompression management. Whether you have a TRITON or a NEPTUN, an update with decompression management will be available soon.

The application of the NGC
comming soon
The NGC app is currently under development. It will allow users to view their dive logs, update their NGC via Bluetooth, and configure their diving settings from their phone.
The NGC app will be available on both iPhone and Android.
