Do they ship with a safety cut-off that detects obstruction, and stops the
processes of opening or closing if something gets in the way?

If not, the OP probably wants to be pretty careful that he isn't building a
legal issue for himself.  A manual-only design can easily get away without
that sort of cut-off on the basis that someone has to be pushing a button to
operate it.

Hook that up to a computer that can't respond to screams and, well...
