Once a company asked for ideas about a COPD and Heart Failure early detector. I submitted my idea (based on Physionet 2016 competition), but the company then asked for a proof of concept. I had none, so I decided to make my own and make it public. I would be happy if it would be copied widely.

The PoC was developped in Java, uses ML and works well enough for me. I have a clear idea how to extend it to detect fibrous tissues in the heart and possibly in lungs. I have confidence that I can develop this, all by myself in the C language, embed it in a self contained $150 device and market it.

However several things worry me: * Having a health detector is nice but is the information really useful? * How to get a market authorization with little resources? * What strategies about next steps, in particular I am thinking about a much more ambitious detector. Some guys, inspired by the Star Trek Tricorder and Qualcomm prize, already had wonderful ideas. Another possibility would be to think about how to integrate an existing organization (I made my whole career in a large company)

Thank for your suggestions.
