Expert is working on a research contract with the US Air Force Academy in area of image processing, GPS designed navigation technology, and over-all control of unmanned aerial vehicles (UAVs). Expert is responsible for the design and development of embedded mission control system software for unmanned aerial systems. This software controls un-manned, autonomous, cooperative, aircraft for missions involved in target search, acquisition and tracking. The control system captured images of potential ground targets; handled image processing; sensor fusion; communications with aircraft avionics; communications with ground stations and other aircraft and un-manned assets; and handled all command and control decisions and processes to carry out the aircraft’s mission.

Expert designed and developed an automated software test system which uses a Laser-Micrometer to measure characteristics of high-precision, milling tools. The system contains motor controller for accurately placing and controlling tool position; measures tool parameters; performs significant digital signal processing including filtering, multi-dimensional curve-fitting and other complex analysis of the data, and displays the results.

Expert designed and developed embedded software for an in-car camera system. The camera system captures continuous running videos of both in car and front of car locations. Video movies from before, during, and after an event are stored to a flash drive when triggered by an event such as a collision, panic button press, or door opening. The camera system contained an accelerometer, GPS, Wi-Fi, USB, and other subsystems. He developed digital signal processing algorithms for sensor processing with in the camera.

Expert designed and developed a 400 watt, switch-mode power supply technology, microprocessor controlled, neon light ballast for a start-up company. The ballast uses SEPIC converter coupled with a push-pull forward convertor, taking AC-line input to 10-KV output. The neon ballast has a number of unique features for which a patent was being pursued. He has been responsible for all the electronic hardware design and development along with the embedded firmware design and development. Digital signal processing algorithms were designed and implemented within the firmware.

Expert was a principal design engineer at ETO for all embedded control of the full line of the company’s RF amplifiers and RF generators. These products are used in MRI systems, semiconductor processing equipment, Laser equipment and other industrial and medical applications. Responsibilities included hardware design of: microprocessor controls using single and multiprocessor designs, DSPs, FPGAs, A/D converters, DACs; analog signal processing, analog filters, analog feedback loops, and linear power supplies.

For EF Johnson, he designed high power, linear RF amplifiers (150 MHz). He handled analog signal processing design. Developed a semi-custom IC design of a tone generator/decoder using switch capacitive filters, analog, and digital processing. This design generated sub-audio tones used for dispatch radios and monitored and detected the sub-audio tones to open the squelch gate on the dispatch radios. Complex digital signal processing was used in the tone decoder process.

He has been involved in both hardware and software product reverse engineering, which in part, consists of comparing the technology in various products to inventions disclosed in a wide range of patents and the claims therein. Products that he has reverse engineered include database systems; media players; audio signal processing and compression; modems; modem compression algorithms; Coriolis mass flow meters; and a variety of other products. He has successfully discovered and analyzed complex digital signal processing algorithms and pertinent operations within these products.

Expert has been an expert witness in multiple patent litigation cases involving encryption/decryption methods associated with databases, and a range of other products. He carried out product reverse engineering and writing of expert reports and claim charts. Analyzed opposing invalidity reports and provided rebuttals. Supported the attorneys on opposing side depositions. He supported counsel on multiple Covered Business Method and IPR patent review cases.

As an expert witness on a patent litigation case involving signal processing within a Coriolis flow meter, expert carried out detailed product reverse engineering of key digital signal processing algorithms within the flow meter. Reverse engineering was originally accomplished on firmware dumps and assembly code. The analysis was confirmed on source code when it was made available through court order. He put together claim charts and expert reports for the analysis.
