They make motion sensor chips primarily. The kind that you might find in nintendo wi, kindle, samsung phones, etc. This is without a doubt a buy long term, there is a very bright future in this space and INVN has a fine balance sheet. But I just rode this from 10.5 to 15 for nearly a 50% increase and I think it'll be a little while before we see any movement like that. Keep in the mind the market helped it reach 15 and if the market were to undergo a correction I could see this dropping back down to 13, in which case I'd buy again.
