Editing User:SL/Borg Logic Gates

I'm mostly just pondering borg logic at the moment.

In order to make borg logic reliable without forcing dwarves to stand around, we may need to base it on a memory gate first. The memory gate requires either water or an animal:
This one uses water: http://dwarffortresswiki.org/index.php/User:SL/Logic_Gates#Memory
This one uses a kitten (or other animal): http://dwarffortresswiki.org/index.php/User:Bidok#Memory

If you use my water-based memory gate, put it on top of a reservoir, aquifer, or ocean. If you use Bidok's, just make sure the door is non-pet-passable, put an animal inside, and have the door leads to a hall that leads to the activity zone (whereever the pets meet normally).

As I design each gate, I'll explain what to link the SET and CLEAR inputs and the OUTPUT to.

Note: It is possible for both the SET and CLEAR outputs to be triggered at the same time on the memory gate with these designs. With the water-based memory gate, this may result in an unpredictible output for a small amount of time. With the kitten based gate, well, I'm not sure what the kitten will do. The hatch would be open, so it couldn't try to go to the door, but would it try to walk up to the hatch, or would it keep standing on the pressure plate until the hatch closed?

Also, these gates are only theoretical and have not yet been tested.

So far, from the NOT gate's design, it looks like these would probably respond slowly (slower than water gates), and would disrupt dwarf tasks on top of it. Not so good. Hmm.

Thoughts before I get DF running:
Do dwarves still cancel jobs and drop items when they run into obstacles which weren't there when they calculated their paths?

'O': Service doors, normally locked - so that you can get in to perform maintenance on the pressure plates and whatnot.
INPUT : All the floodgates, labelled F, and the bars or grates, labelled B. Your input is some lever, or something else, which you want to negate the value of.
SET OUTPUT: 'v' tiles are pressure plates set to detect dwarves, linked to the SET output on a memory gate. They are given a pathing priority with the highest possible value (Important!). They should each also be linked to the adjacent 'F's or 'B's in case a dwarf is trapped inside.
CLEAR OUTPUT: '^' tiles are pressure plates set to detect dwarves, linked to the CLEAR output on a memory gate.

How it works: If the INPUT is ON, the doors are opened, and newly calculated paths will be routed over the SET OUTPUT pressure plates. If the doors are closed, newly calculated paths will be routed over the CLEAR OUTPUT pressure plates instead. This will unfortunately cause dwarves who have already calculated a path through the now-closed doors to run into the doors and exclaim "WTF."
