I read "industrial stapes" and interpreted that as mechanical reference. Industrial staples. Ah-hah! I can understand that! So it must have been a mistype, your "stapes." (I do that allah time, what with my lousy typing.)
Then I looked up "stapes" and found out what you meant. Ah-hah, again!
(I remember something about a stirrup and a cochleus and a drum....or something....but stapes?) Learned something new. Cool.
