This appears to use the libraries from http://greensock.com/ .

I'm not sure how to figure out what libraries are being used in
these examples.

The relevant source for this appears to be:
which cites:
which in turn points to:
whose code is at:
under an MIT license.

One other piece of relevant library information (although not from
any of the URLs you cited, I think) is:
although I couldn't find the source code in
https://github.com/jquery/jquery-ui ; it appears the code may (???)
actually come from:
http://gsgd.co.uk/sandbox/jquery/easing/ (code under a BSD license)
which in turn cites:

A few concrete things in here (other than what you quoted below or
what I derived from that)

 * use an array of points defining a spline, i.e.:

 * http://www.schipholgomultinational.nl/ appears to also use
   greensock (see above)

 * more references to bouncejs as well

So there are a few useful starting points in there.
