I have been to the website of the company that makes this
device or one just like it. Unfortunately, I can't find
the bookmark for you. I was checking out all of the
Rife/Beck/CLark information and came accross it.
I think it is based on acupuncture meridians. It is
associated or at least has some connection to a device
called the F-SCan. If I find the bookmark I will post it.
