Yes. It's a device that we became aware of through the work that our counterparts were doing in the United Kingdom, as were some of our colleagues to the south, in the United States.
Basically, it's a chair that an individual would sit in. They would place their hands and arms on the rests, and through the technology the chair would be able to...not penetrate in a significant way, but penetrate at least a few inches into the body to determine whether somebody has secreted packages in a body cavity. We've been trying out this chair. We've had some success in some places. In other places we haven't, so we're still working with the technology. It's just another tool for us to be able to quickly determine whether somebody has secreted something in a body cavity.
