In this, the third book of the Tesla Presents Series, engineer-historian Leland Anderson provides the transcript of the 1902 U.S. Patent Interference investigation concerning Tesla\'s System of Signaling. The document, \"Nikola Tesla vs. Reginald A. Fessenden,\" which is no longer on file at the U.S. Patent Office, contains Tesla\'s own depositions as well as those of his closest and most trusted associates, George Scherff and Fritz Lowenstein. Included is material on the history of radio-controlled devices, the first practical form of these being Tesla\'s radio-controlled \"telautomaton\" ? an operational boat first demonstrated to the public at Madison Square Garden in 1898. In addition to describing Tesla\'s \"individualization\" techniques for obtaining secure noninterferable radio communications?the patent is today recognized as the fundamental AND logic gate, a critical element of every digital computer?the interference record also reveals that essential features of the spread-spectrum telecommunications techniques known as frequency-hopping and frequency-division multiplexing have their roots in the resulting patents. Furthermore, there are new disclosures by Tesla on the operation of his large high voltage radio-frequency oscillators at both the Houston Street laboratory and the Colorado experimental station. Rarely in the history of science do we encounter such opportunities to gain deep insight into the fundamental ideas and concepts of an esteemed scientist/inventor.
