 The term "compliant" in this context is a mechanical engineering term.
It has been in use since the 80's to describe a class of mechanisms that
take advantage of elastic deformations in some of the elements - like a
flexural hinge or a long flexible segment. In the case of the Clement
focuser, I believe Don is using a type of compliant hinge design to allow
for long travel with no shift. I am sure he can explain it better than I
can.

  OK.  I can't take it anymore!  What in the world is a compliant hinge
or focuser????  Who coined this phrase?  I looked up the meaning of the
word in a dictionary.  Not much help there, since the standard meaning of
the word seems to not have much application to ATMing.  When has ATMing
complied with any standard whatsoever?  So I checked the archives.  The
first use of the phrase is on Jan 1999.  What is the hinge and or focuser
complying to????  Who set the standard for focusers and hinges to comply
to?

like a lot. The compliant hinge design looks to me like it will lead to
VERY stable movements and minimal shift - which is really good.
