Patent number: 9689822Abstract: A system and a method for characterizing a dielectric material are provided. The system and method generally include applying an excitation signal to electrodes on opposing sides of the dielectric material to evaluate a property of the dielectric material. The method can further include measuring the capacitive impedance across the dielectric material, and determining a variation in the capacitive impedance with respect to either or both of a time domain and a frequency domain. The measured property can include pore size and surface imperfections. The method can still further include modifying a processing parameter as the dielectric material is formed in response to the detected variations in the capacitive impedance, which can correspond to a non-uniformity in the dielectric material.Type: GrantFiled: January 22, 2015Date of Patent: June 27, 2017Assignee: UT-Battelle, LLCInventors: Danny J. King, Susan Babinec, Patrick L. Hagans, Lonnie C. Maxey, Edward A. Payzant, Claus Daniel, Adrian S. Sabau, Ralph B. Dinwiddie, Beth L. Armstrong, Jane Y. Howe, David L. Wood, III, Nicole S. Nembhard

Publication number: 20140133041Abstract: A modular solar concentrator having an aspherical primary reflector that is a segment of a paraboloid parent shape. The peripheral shape of the segment is selected to allow arrangement of an array of concentrators in a closely-fitting pattern. The peripheral shape may be rectilinear or trapezoidal. The primary reflector may be an off-axis segment having an optical axis at or near a peripheral edge. In one embodiment, the modular solar concentrator includes a primary mirror and a secondary minor. In an alternative embodiment, the modular solar concentrator is monolithic having internal surfaces that reflect light into the optical fiber. The monolithic concentrator may include a first internal surface that functions in a manner analogous to a primary mirror and a second internal surface that functions in a manner analogous to a secondary mirror. The optical fiber may be secured in the monolith by an index matching adhesive.Type: ApplicationFiled: October 8, 2012Publication date: May 15, 2014Inventor: Lonnie C. Maxey

Patent number: 8653830Abstract: Methods and apparatuses for evaluating a material are described. Embodiments typically involve use of an impedance measurement sensor to measure the impedance of a sample of the material under at least two different states of illumination. The states of illumination may include (a) substantially no optical stimulation, (b) substantial optical stimulation, (c) optical stimulation at a first wavelength of light, (d) optical stimulation at a second wavelength of light, (e) a first level of light intensity, and (f) a second level of light intensity. Typically a difference in impedance between the impedance of the sample at the two states of illumination is measured to determine a characteristic of the material.Type: GrantFiled: December 2, 2008Date of Patent: February 18, 2014Assignee: UT-Battelle, LLCInventors: Lonnie C. Maxey, James E. Parks, II, Samuel A. Lewis, Sr., William P Partridge, Jr.

Patent number: 7881882Abstract: A system for monitoring or detecting tampering in a flexible structure includes taking electrical measurements on a sensing cable coupled to the structure, performing spectral analysis on the measured data, and comparing the spectral characteristics of the event to those of known benign and/or known suspicious events. A threshold or trigger value may used to identify an event of interest and initiate data collection. Alternatively, the system may be triggered at preset intervals, triggered manually, or triggered by a signal from another sensing device such as a motion detector. The system may be used to monitor electrical cables and conduits, hoses and flexible ducts, fences and other perimeter control devices, structural cables, flexible fabrics, and other flexible structures.Type: GrantFiled: September 25, 2006Date of Patent: February 1, 2011Assignee: UT-Battelle, LLCInventors: Lonnie C. Maxey, Howard D. Haynes

Patent number: 5383024Abstract: A wet steam monitor determines steam particle size by using laser doppler velocimeter (LDV) device to produce backscatter light. The backscatter light signal is processed with a spectrum analyzer to produce a visibility waveform in the frequency domain. The visibility waveform includes a primary peak and a plurality of sidebands. The bandwidth of at least the primary frequency peak is correlated to particle size by either visually comparing the bandwidth to those of known particle sizes, or by digitizing the waveform and comparing the waveforms electronically.Type: GrantFiled: July 6, 1994Date of Patent: January 17, 1995Assignee: Martin Marietta Energy Systems, Inc.Inventors: Lonnie C.
