I can see Chips membrane trigger working but, this
I don't get yet.
Sorry, Joe - I missed this one in my post.
"Chip's membrane" (Chip - you are asking for trouble :-) is in
effect a dive regulator's diaphram.
Chip's concept is correct but it can be reduced one
more level.
"Chip's membrane" Methinks we've just
coined a phrase!!! Kewl.

Joe, when you descend the cabin pressure will decrease relative
to the ambient pressure. So that would be a negative pressure gradient
that could trigger the regulator.
Right?

use this system. How? Once the required amount of
ballast water is admitted, you seal off the cockpit so that the regs
take over. Open the valve, the cabin is exposed to surrounding water
and the regs are disabled by default. Close the valve, and the cabin
pressure is now isolated and available to the regs."
I'm sorry Rick, "explain it to me like I'm a two year old" Where the
cabin environment is concerned, where is the negative
pressure required to trigger the regulators on descent?
