Patent number: 10024635Abstract: A landmine-neutralization system has a vehicle including a water supply tank and an electrical power supply and an electro-discharge apparatus. The electro-discharge apparatus includes one or more electro-discharge nozzles each having a discharge chamber that has an inlet for receiving water from the water supply tank and an outlet, a first electrode extending into the discharge chamber and being electrically connected to one or more high-voltage capacitors that are connected to, and chargeable by, the electrical power supply, a second electrode proximate to the first electrode to define a gap between the first and second electrodes and a switch to cause the one or more capacitors to discharge across the gap between the electrodes to create a plasma bubble which expands to form a shockwave that escapes through one or more exit orifices of the one or more nozzles ahead of the plasma bubble to thereby neutralize a landmine.Type: GrantFiled: September 29, 2017Date of Patent: July 17, 2018Assignee: VLN ADVANCED TECHNOLOGIES INC.Inventors: Mohan Vijay, Emilio Panarella, Meisheng Xu, Wenzhuo Yan, Bruce Daniels, Andrew Tieu

Patent number: 7502446Abstract: A soft x-ray generator includes a unique pulse trigger assembly which reliably and reproducibly provides a plasma to initiate the discharge between a cathode and an anode, and having a cone-shaped geometry. The soft x-ray generator of the present invention also includes a rotating anode which is generally disk-shaped with an outer circumferential edge which can be rotated with respect to the cathode to expose different sections of the anode to the plasma discharge, thereby reducing anode wear and providing longer term operation. Anode erosion is also reduced by the liquid cooling of the anode during use. The generator utilizes a relatively low capacitance for the cathode-to-anode discharge and a relatively high voltage and pulse repetition rate (frequency) to achieve continuous reproducible results.Type: GrantFiled: October 17, 2006Date of Patent: March 10, 2009Assignee: ALFT Inc.Inventors: Robert Dotten, Robert Taylor, Emilio Panarella, Meisheng Xu, Yuriy Antoshko, Ian Stanley Chapman, Philippe P. Gratton, David Johnson
