US Patent:

20100283657, Nov 11, 2010

Filed:

Nov 15, 2007

Appl. No.:

11/940425

Inventors:

JEFF L. VOLLIN - Tucson AZ, US
Frederick A. Ahrens - Tucson AZ, US
Kenneth W. Brown - Yucaipa CA, US

International Classification:

G01S 7/38

US Classification:

342 14

Abstract:

The disclosed system, device, and method for diverting a guided missile generally includes a ground-based sensor array generating tracking data of a guided missile tracking a target. A control node in communication with the ground-based sensor array generates targeting data from the tracking data. A phased array directed-energy unit in communication with the control node radiates the guided missile with variable beam width microwave radiation based on the targeting data received from the control node, where the microwave radiation disrupts an electronic component of the guided missile such that the guided missile discontinues tracking the target.

International Classification:

F42B 15/34
F25B 9/02

Abstract:

An open-loop thermal control system and method for components that generate heat includes a reservoir for containing a pressurized working fluid, a first heat exchanger in thermal communication with the working fluid, a Joule-Thomson expansion valve in fluid communication with the reservoir, and a second heat exchanger in fluid communication with the valve. The first heat exchanger is configured to transfer heat from the components to the fluid in the reservoir. The valve is configured to expand the working fluid into a two-phase fluid having a primary use of cooling. The second heat exchanger is configured to receive heat from the components and receive the two-phase fluid. The second heat exchanger provides a single-phase working fluid for at least one secondary use before the working fluid is expelled from the thermal control system.

Abstract:

A method for controlling a power converter that includes a first cell having an output connected at a first node in parallel with a second cell includes sensing a voltage signal at the first node, defining a current set point associated with the converter, processing the current set point associated with the converter to define a current set point associated with the first cell, sensing a current output by the first cell, controlling the first cell such that the first cell outputs a current substantially similar to the current set point associated with the first cell, processing the current set point associated with the converter to define a current set point associated with the second cell, sensing a current output by the second cell, and controlling the second cell such that the second cell outputs a current substantially similar to the current set point associated with the second cell.
