Well, the first example is in a post by Dennis Boseman:
http://news.lugnet.com/technic/?n=11787
I used them in my original and/or gates.
A single piston can give you two stable states, expanded or contracted.
Two pistons can give you three lengths with four stable states:
Contracted/Contracted : length = two contracted pistons end to end
Expanded/Contracted : length = One expanded and one contracted
Contracted/Expanded : length = same as Expanded/Contracted
Expanded/Expanded : length = two expanded pistons
I've used this in pneumatic walkers where I want the feet to have more than just
forward and backward positions. None of them worked well, but not because of
this design pattern.
