Title: The Innovations of Eldon Nerheim
Introduction
Eldon Nerheim is a notable inventor based in Edina, MN (US), recognized for his contributions to the field of explosive technology. With a total of 6 patents to his name, Nerheim has developed innovative solutions that enhance safety and efficiency in explosive applications.
Latest Patents
Among his latest patents is the "Insensitive Propellant Ignitor." This device utilizes a slapper type detonator to initiate an insensitive explosive material. The design features a high-strength housing that confines and dissipates the explosion, ensuring safety during operation. The ignitor retains the explosive material in a collar placed in a chamber with an orifice leading to the propellant. This orifice prevents the shockwave from prematurely expelling the propellant, allowing it to be ignited by the hot gases and particles resulting from the explosion.
Another significant patent is the "Integrated Silicon Secondary Explosive Detonator." This device comprises an integrated circuit built on a silicon wafer substrate, featuring an epitaxial layer and a covering insulating oxide layer. Metal contacts are deposited on the oxide layer through a photolithographic masking process, forming a regular pattern of contact pairs. These pairs are connected by a bridge element, which may be made from the same metal as the contacts or a higher density metal. The substrate is back-etched to create a barrel through which the flyer may travel, enhancing the device's functionality.
