I spoke to Jerry about the glucose sensor because I am a diabetic. He said that the unit they were testing was like a fountain pen, something that would fit easily in your shirt pocket. He said they had high hopes for it as the market for glucose sensing is worth billions, and the first one to do it non-invasively will benefit greatly. He also said that the FDA were very tough on the testing and that they had some issues with results in certain cases (he said they covered someone in coal dust and asked to test him).

In any case, he was optimistic, but at that time, there was no viable product.
