Filed:

May 9, 2005

Appl. No.:

11/126509

Paul B. Lundquist - Tucson AZ, US
Richard Adler - Tucson AZ, US

Eric Lau - Tucson AZ, US

Assignee:

Applied Energetics, Inc - Tucson AZ

International Classification:

F41H 11/136

US Classification:

89 113, 86 50

Abstract:

Systems and methods are presented herein that provide for ignition of explosive devices through electric and/or electromagnetic discharge. In one embodiment, an electrostatic discharge is directionally propagated through air to conduct electric current to the explosive device. The electric current may ignite the explosive device via heat, via triggering of ignition circuitry, via induced electric current conduction to the explosive material therein and/or via direct electric conduction to the explosive material therein. Alternatively, or in addition to, electromagnetic energy may be directionally propagated to the device through a waveguide. Such electromagnetic energy may be in the microwave region and may heat and/or induce electric current in the explosive device. In either instance, the directionally propagated energy may be time varying. In one embodiment, a system is configured with a vehicle to distally position the directionally propagated energy to the explosive device such that damage caused by the device is inhibited.

Abstract:

Certain aspects of the present disclosure provide techniques for a method of removing material on a substrate. An exemplary method includes rotating a substrate about a first axis in a first direction and urging a surface of the substrate against a polishing surface of a polishing pad while rotating the substrate, wherein rotating the substrate about the first axis includes rotating the substrate a first angle at a first rotation rate, and then rotating the substrate a second angle at a second rotation rate, and the first rotation rate is different from the second rotation rate.
