Dr. Direen has reversed engineered a variety of complex systems over the years, including: media players, modems, modem compression algorithms, coriolis mass flow meters, database systems, and a range of other products to support patent infringement cases generating detailed claim charts and writing expert reports to demonstrate infringement. He has successfully discovered and analyze...

Gary L Blank, PhD, PE Engineering Update Institute

Campton Hills, Illinois
Electrical Engineering, Electronics - Control Systems, Motors, Power Systems, Intellectual Property, Instrumentation, Patent Infringement, Process Control, Power Electronics, Statistics, Signal Processing, Communications, Expert Witness, Machinery, Brushless DC Motors, Avionics.
Dr. Blank was elected President of IEEE-USA in 2014 by the 200,000 members of IEEE-USA. As President, he traveled to Canada, Europe, South America, and nationwide (including Capitol Hill) representing and pursuing the interests of the members. Dr. Blank has 40+ years of experience in the design, construction, and manufacture of electrical/electronic control and instrumentation systems. Many of these systems involved the control of motors, electronic devices, both ground and airborne vehicles, signal processing, machinery, and communication. During his term of office as President of IEEE-USA, • he was invited to the U.S. State Department (John Kerry, Secretary of State) to render his opinions on a variety of topics including Standards and Patents, • he submitted comments to the USA President’s Office of Science and Technology as input to a proposed U.S. Strategy for American Innovation on ways the Administration could help technology companies’ programs, • he was contacted by phon...

Robert O Peruzzi, PhD, PE R. Peruzzi Consulting, Inc.

Bethlehem, Pennsylvania
Electronics, Engineering - Integrated Circuits (ICs), Patent Infringement, Mixed-Signal, Analog, Radio Frequency (RF), Signal-Processing, Analog-to-Digital (A/D), Digital-to-Analog (D/A), Control Systems, Semiconductor, System on Chip, SOC
My sub-specialty within the broad category of electrical engineering is with integrated circuits (or complete systems) used for signal-processing, which • Detect signals from a sensor (e.g. antenna, microphone etc. • Amplify, filter, then convert to digital • Process further in the digital domain • Convert the result back to the analog domain for further processing, and/or • Deliver the final output to an actuator (e.g. antenna, speaker, video display, heater control-switch etc.). Examples of these systems are • Mobile and cell phones • Recording and retrieving systems for disk drives or tape • Radio transmitters/receivers and their building blocks such as low noise amplifiers, filters, automatic gain control and frequency mixers (down-converters, up-converters) • Audio amplifiers • Audio recording/reproduction systems • Heat, ventilation and air conditioning controllers • Data transmitting/receiving systems such as serializer/de-serializers (SERDES)
