This CE 156:
But every bit of it titanium and a Venturi control so maybe really a G250 and if a G250T then a titanium back case with a carbon fiber face plate and titanium bump ring, hard purge button of titanium and air barrel and adjustment knob of titanium. And of course a Mk 10 or Mk 5 of titanium.
Electronic servo operated regulators that have an adaptive, learning algorithm that mimics the human breathing pattern and is predictive of future needs are possible.
When we take a step, we do not think about where the earth is, we know it intrinsically from millions of years of evolution, we know the earth will come up to meet the soles of our shoes, no thought is needed, it just happens. When I breath, air rushes into my lungs, this does not require thought, it just happens. That is predictive, I know it will happen without thought or will and that is what I mean by a predictive breathing machine, it does not need to know or compute, it just does what it does transparently to my breathing patterns and needs.
