This design is not a medical device and should never be used as such.
Medical ventilator are really complex devices, they follow strict process of certification and can be lethal if used improperly.
So, NEVER use this device to care a CODIV19 people… nor for anything else than an illustration of complexity of these systems…

What is my system doing :

Control the volume of air pushed into the mask in a NON INVASIVE WAY…
Use a professional dust mask equipped with an exhaust valve (needed to insure security of the system)
Filter the air pushed into the mask
Be able to follow the breathing rhythm and to "help" the user to breathe through the FFP2 or FFP3 filter cartridge. This means that air will be pushed when breathing and stopped during exhalation
Automatically adapt to the wish of the user (plus or minus air volume)
Is a safe system provided it is used with the indicated turbine and the indicated mask

Nice weather app for Android Wear device.
As Peter wrote:
Yesterday I decided to create myself a new Android Wear watch face before I start a new project for a client. The simplicity of B4A meant that this watch face didn't take long to create. I created this watch face to cater for both round face and square face devices, all the code is in one service. For watches like the Moto 360 that has a chin/flat tyre, the code caters for that too (see the screen shot below).

There's an options screen for turning the outer border on or off, for changing the border colour, for changing the background colour of the LCD display and you can also select from either 12 or 24 hour readouts (yes the dots do blink on and off every 500ms). I've added a rear digit alpha SeekBar so that users can set the alpha to their desired preference. Since taking the screen shots I've added a temperature select option to switch between Celsius and Fahrenheit, I've also changed the design and placement of the buttons that allows for changing the border and LCD background colours.
