Sex toys are not regulated in the us?! There are a ton of regulations in the EU unfortunately not the same in all countries but some even classify them as medical devices.

In Germany engineer is a regulated term. Computer scientists wanting to call themselves engineer or software engineer need to complete certain higher education programs. A B.Sc. program in CS is enough for example.
