A magnetron has a cathode, an anode with vanes, and an insulating surface which faces the cathode and receives material from the cathode due to sputtering at the cathode. In an embodiment, a processor mounts onto the center of a substrate with flexible appendages and memory components mount to the flexible appendages. The information processing apparatus extracts a set of pixels whose coordinates fall within a specified coordinate range defined around the coordinate position of the wrist and whose distances from the imaging device fall within a specified distance range defined around the distance of the wrist. In at least one embodiment, the pin may be used to attached a baitfish to a hook by inserting the pin through a lower and upper jaw of a baitfish.
