http://www.beckdevice.com/ Dr. Bob Beck's technology is based on the Patent 5,139,684 & 5,188,738 issued to Dr. Kaali in 1993. Dr. Beck wanted to utilize the therapy by applying the electricity from outside the body, since the method shown in Dr. Kaali's patents involved cutting the artery to move the blood outside the body to electrify it. Dr. Beck designed a circuit that allows to ulitize this invention in a non-invasive way.
