Secret DoD Clearance for 30 years until 2001 (when it lapsed).

EDUCATION From 71-Present: has taken several (~95) Continuing Education Courses and Short Courses since his highest

degree. University of Iowa, Iowa City: Ph.D. in E. E./Stochastic Control and Estimation Theory in Feb. 1971. MSEE in Feb. 1969.

Howard University, Washington, DC: BSEE (Magna cum Laude)/Electrical Engineering (electronics) in Jun. 1967.

Over 38 years experience as a Research and Development Systems Engineer for a variety of airborne and shipborne navigation

systems. H is prior investigations typically included performing trade-off studies by writing computer programs, where he codes up

the algorithms himself and then performs simulation studies using the resulting software. Prior to the 1990 s, he coded his prototype

implementations in the FORTRAN 66/77 or in the PL/1 computer languages and then these programs were later manually converted

to assembly language (by others) for real-time implementation. He had coded assembly language applications himself while at

General Electric R&D Center ( 71- 73). Now he codes his initial implementations in higher level languages like MatLab ver. 6.5 or

in its Simulink ver. 5.0 adjunct (possessing both from The Mathworks) then afterwards sometimes converts select prototypes into

C using a MatLab-to-C compiler (that he possesses from The Mathworks). An alternative that he still frequently uses is to

implement parts of the software solution in Absoft ver. 6.3 Fortran or in Digit Visual Fortran 90/95. He usually uses Microsoft

Visual Basic 3.0-6.0, or .Net and M/S Access 97/2K for implementing Graphical User Interfaces (GUI). He possesses both Wise

Installer ver. 8.12 and PC-Install ver. 7. As an experienced consultant, he has received several subcontracts from major aerospace

primes to debug programs written by others and to write Software Requirement Specifications in his specialty area of Kalman

Filtering. He presents his findings using PowerPoint . He has published 130+ peer reviewed journal papers and company reports

summarizing new and innovative results. He received 1988 M. Barry Carlton Award and $2000 honorarium for Outstanding Paper to

appear in IEEE Aerospace and Electronic Systems Transactions in 1987. He received another $340 award for his technical writing in

a contest sponsored by the U.S. Power Commission in 1967. He s a Senior Member of both IEEE and AIAA and is a 28+ year ION

member (also 8 in MSDN level II) and has served as chairman/vice-chairman of Boston section of Control System Society for 8 years.

4/9/07 To 4/8/09 Google contractor via Kelly Services: Swing Shift Scanner & QA Operator for 2-D images (used Excel).

2004 To Present

TK-MIP as we convert from a pure service company to one offering shrink wrap software product.

Served as Web Master in creating content for company Web Site: www.TeKAssociates.biz

Wrote four technical papers in the estimation and Kalman filtering area as further advertising of our

technical expertise in this same area as our software product. Two are under technical review, two have

already been published in AIAA Journal of Guidance, Control, and Dynamics. Have had twenty-one

research and applications papers published in our specialty since 1991. He founded company in 92.

Took course in National Instrument s ATEasy that handles many different recent Input/Output

protocols including USB, VXI, PXI, Ethernet, RS-232, and GPIB. 17 years as a Windows developer.

Wrote TeK Associates Business Plan for 2006 NECINA Business Plan competition.

2003 (6 weeks) At TeK Associates, with a subcontract from Ar te Associates Navy AROSS program, developed a

Kalman filter-based covariance analysis program using MatLab .

Used covariance analysis program mentioned above and exercised it in performing a quantitative

analysis of the relative pointing accuracy provided by each of several alternative candidate Inertial

Navigation System INS platforms of varying quality (and cost) by using high quality GPS [P(Y)-code,

differential, or kinematic] fixes at a high rate to enhance the INS with frequent updates to compensate

for degradations incurred with time due to inherent gyro drift rate characteristic of each of several INS

candidates being evaluated.

2002(summer) At TeK Associates for Boeing Company:

Prepared a proposal (as specifically solicited) to improve the tracking filter used for National Missile

Defense (NMD) in the application below. Published two papers as an outgrowth of that work.

June 1999 To With a direct TeK Associates subcontract from: Raytheon, Sudbury, MA

October 2000 Served as RADAR SYSYEM CONSULTANT specializing in Tracking Issues

Wrote specialty radar target tracking segments of Software Requirements Spec. for Updated Early

Warning Radar (UEWR)

Participated in the development (and debug), and refinement of parameters in the implementation

and test of various candidate Extended Kalman Filters (EKF s) for UEWR, as implemented in

Fortran on several different UNIX platforms and targeted for eventual C implementation. He

implemented prototypes in MatLab 5.3 and in Fortran on PC for our experiments prior to

translation (by others) into C code.

Wrote an M/S Word memo On use of Lambert algorithm versus use of Levenberg-Marquardt

algorithm for Early Warning Radar target Track Initiation (TI) .

Participated in the writing (using M/S Word ) of the Software Requirements Specification (SRS)

for Raytheon s Batch Least Squares (BLS) Algorithm, for the following extended Kalman filters:

RVCC EKF, RUV EKF, for Interactive Multiple Model (IMM) Filter, and for Track Initiation (TI).

December 1998 Performed System Analysis Studies of Updated Early Warning Radar (UEWR)

To May 1999 with a Tek Associates subcontract from: XonTech, Inc. (Lexington, MA), as

RADAR SYSYEM CONSULTANT specializing in Tracking Issues:

Exercised the same CRLB evaluator for gauging tracking accuracy that had been previously

implemented below for MITRE, and applied it to XonTech s more realistic TD/SAT simulations and

compared results to Extended Kalman Filter (EKF) results.

Prepared and delivered M/S PowerPoint presentation of the above results.

Became familiar with parameter settings of XonTech s software program TD/SAT and its associated

corresponding UEWR radar performance evaluations.

Single-handedly wrote the 150 page UEWR Analysis Design Notebook on Tracking, summarizing the

tracking behavior established to date for UEWR.

May 1997 To Performed System Analysis Studies of Updated Early Warning Radar (UEWR)

August 1998 As a contract engineer to: MITRE (Bedford, MA), via a Gemini Basic Ordering Agreement (BOA) as

RADAR SYSYEM CONSULTANT specializing in Tracking Issues:

Designed and developed and coded a Cramer-Rao Lower Bound (CRLB) evaluator (an area of my

prior published 1974 and 1989- 90 expertise) for gauging tracking accuracy. Personally implemented

this evaluation tool in MatLab 4.2.

Documented the CRLB implementation and its User instructions.

Exercised this CRLB tool to evaluate expected performance of best possible tracking algorithms over

a variety (40) of specified trajectories, as viewed by different Early Warning Radar locations and their

respective characteristics.

Wrote a TeK Associates final report (in LaTeX) and then as a MITRE final report (in M/S Word)

summarizing the results of these CRBL evaluations.

Wrote a White Paper (in M/S Word) for MITRE considering both CRLB and other aspects that affect

radar tracking accuracy for UEWR.

To April 1996 Client: Myself, as CEO/Chief Programmer/acting Advertising & Marketing Manager

Design of comercial TK-MIP software for the PC as a way to quickly and cost-effectively

implement various Kalman filter design options as a prototype so that user avoids the need to do any

programming whatsoever.

Developed and published in several technical conference Proceedings several closed-form test cases to

Verify and Validate TK-MIP and that can be similarly used for any other software of this type.

Implemented TK-MIP Graphical User Interface (GUI) in Visual Basic (VB) 3.0, with other critical

portions implemented in VB 5.0 and 6.0 (as truly compiled modules).

Performed unit and integration testing of TK-MIP . Performed thorough regression tests after

every major change to confirm that no prior functionality was clobbered as a consequence of change.

Prepared two levels of a selectable on-line user guide for TK-MIP to prompt and support both the

novice and experienced user.

Did publicity and marketing: published successful applications in peer-reviewed professional IEEE,

SPIE, AIAA, and Institute of Navigation journals (in GPS use for airborne image collection for

mapping; for image enhancement and multi-sensor data fusion; for simplifying iterated EKF

implementation). Had a total of 9 technical publications in 2001. Four in 2005. Used Microsoft Word
