I have two questions related to rebreathers.

First, I heard that PRISM will be commercialized soon by a company called
"COHRAN" (I am not sure about the name). Anybody have info on this? 

Second, I read on the WWW rebreather page of Eric (Thanks to him) the
description of the BMD. It is said that, this semi-closed rebreather use as
feeding gas Air and that the percentage of O2 still acceptable even on
surface. My understanding of semi closed technology is that there is a
degradation of the O2 level down to a plateau/asymptote where it is
stabilized. To achieve this, semi-closed reb. are usually fed with a nitrox
mix so the plateau is within an acceptable O2 percentage range.
If any could explain me the BMD technology i'll appreciated as it is a
mystery for me!

Thanks.
