So maybe you could describe the pipeline, things go from, obviously, an idea to something that becomes a research project, and then maybe it turns into a venture. Maybe you could explain the process. As most of you can imagine, it starts with a problem. The process, it begins with the analysis of the problem looking at the attributes of the problem, and when I say attributes, you look at how big is the problem and how is that problem currently solved? Are there opportunities to improve that solution? Or sometimes, you stumble on problems that haven’t been solved. So you spend a lot of time understanding the problem. Probably, during this first concept stage, 80 or 90% of my time goes in understanding the problem. I feel that the more time you spend with a problem, the better chance you have of coming up with a good solution. So I think just to give the audience a sense of the range of topics that you tackle, I think it's overwhelming, I cannot even imagine that one person can be a master of all these different fields, maybe you could give us a sampling of some of the projects you have going on right now. Probably about half of them are in implantable devices. There's one company developing a gastric pacemaker for the treatment of obesity. Another one is focused on treatment of chronic pain with an implantable stimulator. Another one is developing an implantable device for the treatment of atrial fibrillation. Another one, which is a very exciting company, it's a drug device combination for the treatment of epilepsy, so it's an exciting novel approach, and I collaborated on that project with some scientists at Duke. There are a couple of others - an artificial prosthetic colon and rectum company for people who have colostomies due to cancer or what have you. So we couldn't potentially restore normal function, and then, another one which is focused on inflammatory bowel disease. So a whole range of things. How do you become so well-versed ...
