So that's cholesterol. We have a kidney stone detection device. Here we take a drop of urine from any random sample and just add a proprietary series of proteins, which are actually in one little vial, and sit it on a card. Based on the drying pattern, we're able to tell whether someone is in the active phase of forming a kidney stone or not. With that, they are then able to monitor their dietary intake, medications or whatever, so they don't get a full stone incident.
Some companies have.
But, more often it's actually inventors or university groups that come to us. More often than not, we agree to fund all of the development of any one invention. The inventor will take a royalty back and they may take some shares or options. We've been doing this since 1993. I'm the founder of the company.
