Issue area, that's a little -- it's clearly shifting -- we have over 200 patents now. Counting is very difficult because we're buying patents as we're buying – just the last quarter alone, we buy 14. The lawyers love us anyway right now, they basically live here. I think we have about 50% -- no, about 45% -- 40% of them related to display and display systems. And I think as you can understand, that's where our original situations are. We have now software, a lot of software patents. We are now -- I'm very glad that we've got the 4 patents for aero sound [ph]. They are the most original patents in this whole area of speech. Those patents come in Japan, United States, China, and they all issue patents. So we're very glad to have that. So we're still building there. In fact, last quarter alone, we filed 3 speech patents. Speech is going to be a big thing for the wearable. If you don't have good sound, good speech, you can forget about wearable. So we are building that. And later on, just stay tuned, we're going to have additional announcement in this area. We want to be the #1 speech in the entire world. So that's another area. And ergonomics, as we well all know, wearing something over your head is a huge issue. And now, well, of course, we have a lot of experience with the military so we know what it does take and what does not take. And we already have patents in it and we're going to find additional patents, some of them are design patents. So I'll just go on and on, we can talk about it. I'm very excited about this area. It's not over yet. We're still are just seeing the beginning part, I would even say the inflection point is being reached. The inflection point will probably be early next reached, and then it becomes very clear. So that's why we're very active in acquiring patents, acquiring companies and people because I think next year, those prices will be very different.
