Filed:

Mar 15, 2006

Appl. No.:

11/376505

Inventors:

Brian Spears - Dublin CA, US
John Wood - Tempe AZ, US
Nicholas Tufillaro - Corvallis OR, US

International Classification:

G06F 19/00

US Classification:

702085000, 702001000, 702107000, 702106000, 702108000, 702109000

Abstract:

A mixer measurement system and method use a chaotic signal to characterize a mixer under test. The mixer measurement system includes a chaotic reference source, an excitation source at an input end of the mixer under test and an inverse system at an output end of the mixer under test. The inverse system removes a chaotic component from a response signal from the stimulated mixer under test to produce a recovered signal having an included distortion that is characteristic of the mixer under test. The method of characterizing a mixer includes applying the chaotic stimulation to the mixer under test to obtain a response signal and employing the inverse system to remove the chaotic component from the response signal.

G21B 1/19

Abstract:

Methods, devices and system for asymmetric inertial confinement fusion are disclosed. One method includes a fixing in position a target capsule comprising an inertial confinement fusion fuel, where the target capsule is substantially spherical. The method further includes for applying an oscillatory compression to the target capsule. The oscillatory compression includes compression at a first time in a radial direction orthogonal to a diametric axis of the target capsule, and compression at a second time along the diametric axis to drive the target capsule into driven into an ovoid shape. The oval shaped target can implode upon being further driven at a third time.
