Title: John T Naff: Innovator in Spark Switch and Acoustic Technology
Introduction
John T Naff is a notable inventor based in Pleasanton, CA (US), recognized for his contributions to electrical and acoustic technologies. With a total of 4 patents, Naff has made significant advancements in the design and functionality of spark switches and acoustic devices.
Latest Patents
One of Naff's latest inventions is a spark switch featuring coaxial electrodes with increased electrode surface area. This innovative design includes an inner electrode surrounded by an outer electrode, which substantially enhances the exposed overlapping surface area. The increased surface area results in a proportional increase in the operational life of the switch. Additionally, the outer electrode is designed to shield a surrounding insulation layer from debris, preventing contamination. Another significant invention is the acoustic cannon, which consists of multiple acoustic sources arranged symmetrically in a planar array. This device generates pressure pulses that exit as sonic pulses, creating a Mach disk, a non-linear shock wave that travels efficiently. The acoustic cannon serves as a non-lethal weapon, useful for crowd dispersal or disabling hostile targets.
