My child was diagnosed with type 1 six weeks ago. I'd love to have this for him.

I would not consider it for anyone but an adult with diabetic experience We have always seen articles in areas of speculative new devices. Most do not work out well. I would look for an Endo with a good reputation and try to learn the ropes. Learning takes much time and multiple sooirces. Some day we will have better devices. ----== Posted via Pronews.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.pronews.com The #1 Newsgroup Service in the World! >100,000 Newsgroups ---= - Total Privacy via Encryption =---

The basic mechanical technologies were solved at least 25 years ago to my knowledge, the sensor is the problem. With good sensors, you don't need fancy computers. It's a simple damped feedback loop like physics and engineering students have been tuning since the invention of feedback loops. |
