Nakamatsu Yoshiro's patents.
EDIT: Google link fixed! Chris, one of my readers, was kind enough to fire over to me a link to Nakamatsu Yoshiro's portfolio of patents, courtesy of Google. There is some fairly mundane stuff in here, like a couple of patents related to golf clubs, a device for increasing the activity of the human brain, and some just plain nifty stuff. I get the feeling that this is only a partial list, because he's reputed to have a couple of thousand under his belt.
