Thank you. I had a few questions, so I appreciate Mr. Aspin sharing his time with me.
You talked about the three different types of technology. I realize that you haven't actually studied them based on the necessity for any kind of monitoring. Obviously, it sounds like you know these three systems quite well, and you said you didn't want to bore us. It's not really boring for us, and we really need it spelled out really simply, and we probably need it spelled out two or three times.
It's not something that many of us have studied a lot. I wonder if you could just explain GPS radio frequency and biometrics in some other platforms in which you have used them, or other technologies or other purposes that you may have not used but have studied. I found your GPS explanation very helpful, and I actually would like you to have gone into more detail. If you can just do that in a little more detail....
Talk slowly for all of us—not you.
