Hi,
take a look at www.infodev.ca/.
This company uses J as a prototypyng tool and in production code for people
counting systems. Code is translated to C only if necessary.
The owner, Pierre Deslauriers, wrote APL code for the development of a
cochlear implant device back in the 90's.
You can read the article about it in the "APL '93 Proceedings of the
international conference on APL" :
