	The idea that *WHEN* the filaments melt the sensors operate
	make me think of the idiot lights in cars now that go on 
	only when there is a problem ie; oil light comes on when
	you have run out of oil pressure (as well as oil) with out
	warning. I'm sure that the engine filaments we speak of here
	are not like that. (?) Are they,...........
