Summary
Most of my career has been devoted to devising novel sensors and associated signal processing. Some of these sensing systems make novel use of inferential, indirect sensing using local bioreporters sensed remotely. Some of these sensing systems fuse data from many sources to draw inferences from automatable hypothesis testing. I was the conceiver and principle advocate for a early-stage effort at DTRA to exploit indigenous botanicals as indicators of militarily interesting items. I am an advocate for a genetically-modified botanical energy crop solution to the nation's evolving vehicular fuel crisis. An analysis I did some years ago identifies the rate-limiting, photosynthetic conversion deficiencies of plants and identifies botanical physiological modifications needed to achieve an optimistic 7% solar conversion to ethanol efficiency. Best guess: a solution is 30 years off if the initiative were started immediately and progressed in an unfettered manner. For the past 40 years I have been quietly working at the very fundamentals of all of physics; and devoting considerable effort developing a new cosmology around a novel geometric explanation of Special Relativity. Early success with the gravity part explains Dark Energy and Lunar Orbital Recession, the anomalous gravity of the Pioneer Spacecraft and the spiral appearance of most galaxies. For the past 15 years, the principle efforts have been directed at explaining particles and particle mass in consonance with the new perspective of Special Relativity and a reinterpretation of the Dirac relativistic wave equation. The result is that I have a explanation for why particles have only one unique rest mass, particle charge, moment and mass-energy and inertia during acceleration; and can show gravitational attraction as an immediate consequence of the explanation for mass. Those who are interested are invited to visit my cosmology website to see how far I've advanced the cosmology.

Work History
Senior Principal Engineer
Bioreporter Sensing
- For Sensors and Signal Processing I supported the Arms Control Technology Division (ACTD) of the Defense Threat
- Reduction Agency (DTRA) on Dyn’s SETA contract with DTRA
- Computer
- Science Corporation bought DynCorp shortly before the end of my employment
- Vegetative Effects Environmental Sensing
- I conceived and proposed a $60M, 5 – year program to develop vegetative signatures suitable for sensing the presence of AP Landmines and Chemical
- Warfare chemicals through the agency of plants to the Defense Threat
- Reduction Agency
- On my advice, DTRA spent about $3M over a two year period advancing this technology before it was zeroed in the wake of 9-11
- I was also the author of the 2002 DTRA SBIR topic styled something like
- Botanicals as Bioreporters for the detection of CWAgents and reviewed the resulting proposals to select the winners
- See the presentation titled "Vegetative Effects Environmental Sensing Decision Brief" under my
- Publications, below
- Plants are rooted in their environment and react to novel environmental influences in telling ways
- Hypothetically, local vegetation should show perceptible effects of TNT and CWA exposure because TNT and CWAs are toxic to plants
- Testing proved this conjecture correct
- See my presentation, titled "Plant Effect Environmental Sensing (of TNT and other toxics" under my
- Publications, below
- Technology
- Upon my advice, DTRA supported the development of several bioreporter – reliant electro – optic technologies proposed by proponent companies responding to solicitations, including: a LIDAR technology to sense unique gases produced by soil bacteria ingesting TNT from landmines; laser induced fluorescence of genetically – modified soil bacteria that fluoresced green (but not when exposed to TNT) and a fluorescence imaging technology that demonstrated that many plants show novel fluorescent signatures from their leaves when exposed to TNT and AMPA (a simulant for GB nerve agent).

- Knowledge of these deficiencies and causes offers considerable opportunity for intentionally exploiting the sensing system to operate in a way that may be unexpected by its owner to give bogus results
- I have a fascination with spoofing sensors by exploiting their weaknesses.
Consulting Scientist
ENSCO, Inc
01.2003 - 01.2004
- Magnetic Effects Sensing
- As a Consulting Scientist supporting a team developing technology for sensing occulted facilities, I conceived, designed, built and tested a new sensor to sense occulted metallic objects
- The sensor I invented relies on the fact that resistance and inductance in an electric coil are affected by conductive and magnetic properties of objects permeated by the magnetic field
- The new sensor discriminated various metallic and magnetic materials and sensed objects at distances up to a foot with only a three inch diameter coil
- Hyperspectral Imaging
- As a Consulting Scientist, I demonstrated for an unknown customer that anomalous scene clutter filtering could be used for detecting deviations from the normal mix of vegetation that may be telling of items of military interest

- I tested the filter against AVIRIS spectral data of various species of trees to develop the Receiver Operating Characteristic of a hypothetical alarming-function hyperspectral imager
- Such novelty is from an unnatural botanical species mix, a herbivorous insect infestation of the trees or other causes that might present perceptible vegetative spectral effects and deviation from the normal spectra
- The analysis results of several hyper- spectral vegetative effects sensor data processing ideas are shown in "VEES

- The results are summarized in a report to BMDO/AQS titled Endoatmospheric IR
- Seeker - Interceptor Performance Limits
- See the plot of the simulation results titled "Endoatmospheric IR Seeker - Interceptor Performance Limits" in my
- Publications, below
- Page 11 of 17
- I analyzed THAAD - like IR seeker - interceptor – RV engagements to determine an optimal intercept altitude accounting for target signal transmission through the hot sapphire window and optical train, the three largest noise contributions to focal plane array (FPA) signal, and the effects of the thermally emissive "hot" sapphire window

- Measured the emission patterns of optical fiber bent tightly around various diameters of drill stock
- Diagnosed a polarization noise problem in a fiberoptic test instrument being developed for the market and suggested the lowest cost solution to the problem
- Optimized a monochromator for TTC's optical fiber test and evaluation laboratory
- TTC has become Acterna
- The linear polarization of light from a laser diode corkscrews as it propagates down a single mode optical fiber and thermal fluctuations in the fiber core cause the linear polarization to wiggle angularly at each of the cleaved surfaces at the optical connectors
- Complementary portions of the light will be in the S and P orientation at each interface and (according to Fresnel’s
- Equations) the reflected and transmitted light is different for each orientation
- Page 8 of 17
- The cleaved surfaces aren’t perfectly perpendicular so the reflected and transmitted signals are noisy because the S and P components wiggle with the polarization
- The diagnosis was confirmed when the linearly-polarized diode laser was replaced with an unpolarized light emitting diode (LED) and the noise floor dropped dramatically
- This is because the light polarization from a LED is uniformly distributed across all 360 degrees of angle and there will be no fluctuations from S and P differences at each connection.

- Carbon Tetrachloride is electrically non-conductive and has a known room-temperature heat capacity and low vapor pressure and is suitable for such a measurement
- The rising and falling temperature of the Carbon Tetrachloride was taken as a function of time with each of the immersed ICs initially operational and then turned off to get heating and cooling curves
- The heating and cooling curve data were fit to the two applicable linearized thermal transport equations and these were solved for the unknown beaker heating and cooling rates from which the IC heating rate was estimated using the mass and heat capacity of the fluid
