But generally you notice something is wrong, and it won't kill you. I think that is the difference with rebreather control systems. Firstly, not many computers control life support systems where a failure, if unacted upon, will result in death. I think the term "failsafe" means that in the event of a malfunction, the system/device is still "safe". (eg joints on Newtsuit). Maybe I'm wrong. Remember, this computer will control the addition of oxygen, too little and not enough is almost unnoticable to the diver. Secondly, of the computers that control life support, how many have to operate in SALT WATER under hydrostatic pressure? Salt water and electronics don't mix. > we trust computers with the world's missle launch systems. The reason I am sure that some human factor is in the launch sequence, don't you? No human trigger is required to add o2 to a breather, under normal use. >that they work the way they are intended is that they operate under >specificied conditions & THERE IS USUALLY >MANUAL OVERIDE. Sure is! See the post re software testing and bugs on this thread. >As for point 2, being the OCEANIC presentation....since I know the person >you >are talking about quite well (and he is on this list) I will leave it up >to them >to pass comment.....but I would recommend you don't visit Sorrento or >Melbourne >on your dive trip to the Mount next week!!!! I don't know this person, only what he said. The reference was to make a point, not point the finger. I would be happy to defend my statement. Rod Nairne.
