 So, we have built this setup to demonstrate how precise, how dynamic can be U2-YBN tracking. This is a fantastic technology. If all works, it's running on our legacy products, it's running on an MP1 processor, and it is showing how far you can go with new applications relying on U2-YBN. So, inside the bowl, we are inserting this tag, and inside the tag, there is this circuit board with our legacy U2-YBN transceiver that is sending and receiving U2-YBN pulses to measure distances with the various antennas that are surrounding the pitch. The distance between the bowl and the antenna represents a circle. This is a circle that represents this, and for every antenna, we have a circle. At the intersection of every circle, that's where the bowl is located. Here we go.
