The path to decompression

[pisoiu]

I am contemplating with the idea of creating a dive computer which may have aditional functions like navigation, etc.
It is a long shot, I am not trying to do some DIY gadget. The goal at this point is to create a commercial product. But as I said, it is a long shot and for now I am only evaluating the possibilities.
What it concerns me at this point is the decompression algorythm required to be implemented in such a computer, as this will be its basic function. I understand the mechanisms involved in decompression practice, not at their finest details, but I understand them. What would you consider to be the best path to follow, in order to gain the knowledge required to implement in practice all models used at present (buhlmann, rgbm, vpm, etc)?
-to study books on this topic (ex. Deco for divers, Powell). Is this book ok for such a purpose or are there other books. Recommandation?
-to search for scientific articles on this problem? Where?
-to cooperate with institutions specialized on this problem? I imagine there are not many...

Thank you.

Get a job with a dive computer manufacturer in their engineering and/or design department.

Depending on where you think your market might be, you really should be looking at product liability insurance... then you or a contractor needs to have the basic skills in programming and mathematics to write a program to run a decompression algorithm... which unless you use an outdated Buhlmann model, may cost you a license fee. There are several people who subscribe to ScubaBoard who have written decompression software. You should do a little detailed research and look them up.

I don't think there is any in 1000 miles radius. And besides that I run my own business in electronics design from 10 years.
But thank you anyway.

LE: Doppler, I saw your post just now. I have all the technical knowledge to do it, I need the documents to start with. This thread should be the research you are talking about and the research I need. So far I do not know where to start.

Deco for Divers is a good starting point, but will not provide in depth knowledge of Algorithms.
You might want to search the Rubicon Foundation, and/or contact Decompression software for the diving world | www.gapsoftware.com.
Of course searching the web for the names Baker, Wienke, Yount, Pyle, Workman or Bühlmann (to name a few) will provide enough reading for months

No offence to any of the true subject matter experts on SB (and there are many here), but if you rely on this forum as your research source you're not doing due diligence in your research. Asking people to simply provide you with the answers is NOT research and could lead to possible issues later in your design phase when someone says (with validity) "this was my algorithm/concept/idea and here's the forum thread to prove it".

If you're serious in your plan license an existing model and go from there.

Consider Bruce Wienke's books. They are very heavy on the math of decompression theory. They would be a good place to start.

This web site DIY DECOMPRESSION gives the fundamentals of implimenting Buhlmann in a psuedo code format that anybody with a basic understanding of computer language can figure out. I did some code ib C that actually worked. It would be very easy to modify the code to include gradient factors. The only thing I had trouble with was figuring how you tranition from NDL dive to mandatory deco dive but I am very weak in programming so I'm sure someone with some coding experience could come up with a solution.

Good luck Keep us posted.

Adrian,
It is not my intention, by far, to get from here or from anywhere else on the internet, a paper with some formulas on it, implement them on a microcontroller and sell it as a dive computer. A device which can affect someone's health or life cannot be designed that way. That much I know after some years of designing embedded systems. In part it is my fault, english is not my native language and perhaps my ideas are not expressed in the best way possible.
What I need is a starting point, some authors and books names, a trail. As it was kindly provided by other persons who posted here. That is exactly what I'm looking for, to know where to look for information I need.
My respects and thank you very much for provided information.
Of course I will post updates on my research, but I expect this to be really slow. There will be much information to be absorbed and the time dedicated to this project is not as generous as I would like it to be.

Gee Steve I doubt the top dive computer manufacturers in the world would consider Buhlmann outdated especially when you apply gradient factors which many have done now.
