Electronics Engineering Expert 508590 AL

Expertise Description

I have over 30 years of experience as an engineer designing and developing products in the electronics and software industry. My expertise includes control systems; embedded systems design and development; XML database design; control UAVs (Unmanned Aerial Vehicles); bio-informatics, and product reverse engineering. I have a broad base of knowledge in electronic and software systems gained in my career working on various product designs for a number of companies. I developed embedded control of high power RF amplifiers used in Magnetic Resonant Imaging systems. I was chief architect developing a novel XML database system. I developed DNA and protein sequence search algorithms and software used for bioinformatics. I am working with a research group on control of UAVs. I have reversed engineered a number of complex systems, including: media players, modems, modem compression algorithms, coriolis mass flow meters, blood analysis meters and a variety of other products. I have successfully discovered and analyzed complex digital signal processing algorithms and pertinent operations within these products. I have taught engineering at both undergraduate and graduate level classes. I am an inventor of three patents associated with the XML database technology. I have prior expert witness experience with consultation, deposition, and courtroom testimony.

Areas of Expertise

Expert Witness

My expert witness experience includes multiple patent litigation cases involving encryption and decryption methods associated with databases. I have carried out product reverse engineering and writing of expert reports and claim charts. Analyzed opposing invalidity reports and provided rebuttals. I’ve supported the attorneys on opposing side depositions. I have been an expert witness on a patent litigation case involving signal processing within a coriolis flow meter. I carried out detailed product reverse engineering of all the 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 made available through court order. I generated claim charts and reports for the analysis. An expert witness on a patent litigation case involving a hide and seek toy doll. I carried out product reverse engineering, writing of a claim chart and expert report. He provided support for the legal team and wrote rebuttal reports for non-infringement arguments and patent invalidity arguments.

Consulting Experience

I am responsible for the design and development of embedded mission control system software for un-manned 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.

I have designed and developed an automated software test system which uses 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, multidimensional curve-fitting and other complex analysis of the data, and displays the results. This is an on-going project with new features being added regularly.

I 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 patents are being pursued. I was 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.

Professional Experiences

I have designed and developed analog circuitry throughout my career as an engineer. I have worked with TVs as far back as high school, so I understand the circuitry and technology of the patent.

I currently do research with the US Air Force Academy which in part involves image processing. Images and video for some of the cameras we use are interlaced which we de-interlace before processing. In addition, I have a strong background in digital signal processing so I understand the technology of the patent.

I have deep experience in working with law firms in patent litigation cases and can help with both patent invalidity and demonstrating non-infringement of the patents.

I have worked with a number of companies throughout my career, designing and developing product in a number of fields including: UAV research, XML Database, MRI high powered RF amplifiers and RF generators for semiconductor processing equipment, and a range of other products and systems. I have taught engineering courses. I have reverse engineered a wide range of electronic and software systems, writing claim charts to support patent infringement cases and I have been an Expert Witness on several patent litigation cases.

Relevant Experiences

I have a very strong background in all levels of software design, development and reverse engineering . I also have a background in computer systems design. I have worked at the low level interface of software with computer hardware up to the graphical user interface level. I have worked with computer hardware and software since the 70’s time frame.

I do have experience with IPRs and CBMs. I am currently working with image and signal processing on a research contract with the US Air Force Academy.
