PROFESSIONAL HISTORY
R&D Consultant
Edge Technical Associates LLC, 1999-2000, 2002-present
Projects for client Sarnoff Corporation, now SRI International (2010)
NOVA project: Real-Time WAAS Video Tracking
Performance evaluation tools
Developed tool to generate track-oriented ViPER (Video Performance Evaluation Resource) XML
from the tracklet-oriented XML output of NOVA, a real-time, wide-area, multiple-target video
tracking system. Output is compatible with ViPER-GT ground-truth authoring tool and NIST F4DE
(Framework For Detection Evaluations). Started from a prototype developed by Sarnoff staff. Used
C++, STL, BOOST, MSXML.
Developed and documented methods and workflows for using these tools.
Fixed bugs in real-time tracking system related to XML generation. As part of this work, fixed a
track/frame alignment bug in tracking system by revising inter-thread and inter-process (MPI)
communication (joint work with a staff member).
Field Exercise Support
Proposed and demonstrated using MATLAB a novel mechanism for scene-based Non-Uniformity
Correction (NUC) of extinction artifacts in a shutterless, segmented image sensor.
Developed a tool (in awk) to select co-synchronous video frames from asynchronous segmented
camera arrays. Used this tool to obtain usable video from samples that were available but unusable.
Proposed & set up Linux-based CIFS (Samba) server to work around speed limitations of Windows-
based drivers that are available for reading high-resolution video data from ext3 RAID file systems.
Used this server to make daily video drops from TNT10 field exercise available to team.
Road marking for EA10 and OA/DT3 field exercises.
Edward J. Segall, Ph.D.
Other
Ported tracker build environment to Windows XP x64.
As part of this work, found a fundamental application design flaw that must be fixed before upgrading
to latest development tools, and that may be responsible for functional issues.
Wrote road marking guide.
Worked with other team members on a wide variety of build issues, concurrency problems, memory
issues, and other problems.
Projects for client TruePosition Inc. (10/2004-12/2009)
U-TDOA Location Processing Accuracy improvements
Improved 95th percentile accuracy of TruePosition s core location technology by 10%.
Co-recipient (with Chief Scientist and Senior Scientist) of TruePosition s 2008 Invention of the
Year award for this work. (Only non-employee ever to receive this award.)
Used C (Visual Studio 2005) for the programming portion of this work.
U-TDOA Location Processing Reference selection
Led resolution of anomalous GSM reference selection metric values found in testing.
Coop Generation (Selection of Demodulating and Cooperating Receivers) Algorithms
Developed and verified coop generation algorithms for Distributed Antenna Systems (DAS).
Invented, developed and verified coop generation algorithms for UMTS and other air interfaces
that use selective combining.
Resolved long-standing result inconsistencies among Solaris, Linux and Windows builds by revising
core data structures. Developed tests that reproduced the discrepancies and verified the fixes.
Used C++/STL for development (Visual Studio 2005 for coding and unit testing, with gcc and Sun
Workshop for cross-platform integration, testing and verification). Used Perl for generating test
configurations, DOS scripting for testing, and Excel for analysis & communication of results.
Real-time resource scheduling
Invented, developed and verified load- and fault-tolerant scheduling method for LMUs (Location
Measurement Units). Used C++/STL for development (VS 2005 for coding and unit testing, gcc for
cross-platform integration, testing and verification), and MATLAB for visualization of results.
CGI+TA and E-CID location processing
System engineering, software design and implementation for multiple features and updates.
C++/VS 2005 (development, unit testing), gcc and bash scripting (cross-platform verification).
Simulation/Modeling
Improved Accuracy Prediction tool speed by 50X and halved memory footprint (made server farm
obsolete). Improved robustness across multiple platforms. This tool has been used to successfully
engineer nationwide networks and has brought in new business through proposal support.
As part of this work:
Ported to C++ a Java implementation of CBCA algorithm (fast cell-based polygon containment);
found and fixed day-1 bugs (carried over from the Java implementation).
Using encapsulation and inheritance, integrated the C++ implementation into a related tool as a
first step towards elimination of redundant code.
Made numerous stability improvements, bug fixes and feature enhancements in both tools.
Designed and developed (in C++) a domain-specific comparison tool for comparing related results,
measuring their differences and formatting the differences for visualization.
System engineer and subject matter expert/internal consultant for accuracy prediction + related
tools. Developed baseline reference results, test configurations and pass criteria for regression
testing. Worked with QA department to address all discrepancies over multiple major releases.
Used MS Visual C++ for development and profiling (code is mix of C and C MapInfo for
visualization, and DOS for scripting unit level tests.
Configuration/build/release management
Improved internal release process for library code that is incorporated into multiple system
components and standalone tools.
Managed and performed release builds of those tools and release labeling of library code in
coordination with SMLC team, SCOUT team and Release Engineering (ClearCase, Perl).
