Jeffrey K. Cunningham
—J. K. Cunningham, LLC
A contract services company providing engineering,
analysis and development.
- Developed signal processing algorithms improving
Ascan performance of ultrasonic measurement systems for
non-destructive testing of steel walled pipelines for
Quest Integrated Group.
Managed program upgrading existing products with improved
algorithms, working with FPGA engineers and embedded programmers to
meet timing, verify performance and validate desgin. Designed robotic
ultrasonic laboratory measurement system using a modified 4-axis CNC
table and quaternion-based motion control g-code generator.
- Developed autonomous purchasing agents using Ruby and
Selenium, the core technology for web startup Netplenish.com. Solved problem
with poor quality affiliate product feed data driving high levels of
customer servicing by designing a real-time price and availability
and implemented web-based performance monitoring system in Lisp.
- Built toolchain and updated Linux kernel and drivers
Corporation's proprietary motion controller board. Derived the
equations of motion for a 5-axis motion controlled waterjet cutting
head using quaternions
instead of classical Euler angles to
improve accuracy and reduce computational load on embedded processor.
Proposed alignment and calibration technique applying least-squares
optimization to over-determined measurement sets.
- Designed web-based system enabling customers to
virtually 'try on' hats for Lady Diane
Hats. Nginx+Php+Jquery+Octave-based system employs
—active contour image processing—to locate
head outlines from uploaded portraits, then cut away
background to transparency, scale and sandwich between
hat back and foregrounds to produced final fitted
image in real time.
- Wrote threaded master control loop model and provided
software architecture solutions and advice on Intrepid
Systems autonomous robot entry in NASA
Sample Return Challenge.
|2008 - 2010
Principal Signals Engineer
—SAIC Space Systems Division
A $10B company providing scientific, engineering,
systems integration, and technical services.
- Implemented software signal processing components of
satellite communication system in Matlab and C++. Solved significant
performance issues by re-engineering parallel-processing architecture
employing MPI-based architecture on multiple Linux-based blade
- Developed quaternion-based orbital model and link
budget for nanosat communication system using Lisp.
|2003 - 2008
Principal Systems Engineer
—The Boeing Company
An $88B American multinational aerospace and defense corporation.
- Created high-performance, high-resolution image
processing library in C++ used to perform detection and feature
extraction on satellite radar imagery.
- Designed and implemented criteria and testbench for
analyzing performance of air-to-surface seeker missile
homing algorithms using FLIR imagery. Re-engineered
existing Government laboratory code to improve
performance, maintainability, reliability and
- Developed accurate link performance model for global
airborne satellite communication system—Connexion by
Boeing—used to determine power and bandwidth constraints
applied to transponder channels on commercial aircraft Internet
services. Employed a variety of languages, including C++, Lisp and
- Designed and implemented telemetry analysis tools
used to remotely monitor performance and detect link degradation on
in-service aircraft prior to failure. Isolated a difficult problem by
correlating aircraft geolocation and orientation with link degradation
due to differential deterioration of left versus right polarization
antenna feeds to phased arrays on aircraft.
|2000 - 2003
Communication Systems Engineer
A $180M Startup that developed dNTSC
technology to embed and recover wideband data in broadcast television
- Designed fixed-point FIR filters for modulator signal
processing block using original optimization technique to meet
challenging size and speed requirements in FPGA modulator.
- Responsible for FPGA validation which included
development of Matlab unit test framework, test vectors, operation and
troubleshooting. Led team responsible for lab verification of FPGA
implementation and continued regression testing throughout revision
- Developed C++ reference model for ASIC demodulator
signal processing block used in both validation and
verification. Components included FIR filters, QAM modulators and
demodulators, complex wave-shapers and adaptive decision feedback
- Responsible for debugging, test and tuning phases of
ASIC signal processing design.
|1993 - 2000
—The Boeing Company
- Developed and maintained GUI-driven performance model
for airborne links between Kx and Ku-band phased array antennas and
geosynchronous satellites. Written in Visual C++.
- Wrote GUI-driven program to import scanned images of
satellite EIRP and G/T earth foot prints, register
landmarks, and rasterize into geographical grid of
interpolated values using LMS fit to find map
