Sierra Video Systems

• United States
• Computer Hardware Manufacturing

• Executive Vice President of Engineering

  • 2003 - 2005

  As VP of Engineering, I defined professional audio/video routers and terminal equipment products and feature sets in conjunction with Sales team members and customers. I developed mechanical and electrical design criteria including, in some cases, detailed design of subsystems and feature definition. I allocated design work to a team of software and hardware engineers as well as PCB designers. I also defined test processes and assembly sequences.

• Senior Design Engineer

  • 1995 - 2003

  As a Senior Design Engineer, I defined feature sets, determined chassis and board dimensions, designed PCB's (schematic and layout), created FPGA code, coordinated with software developers to implement features using my hardware designs, wrote calibration and test procedures for in-house production staff, and wrote user guides for terminal equipment products. This work included 1 Hz to 400MHz analog signal routing, professional video and audio ADC and DAC products, audio/video time delay products, audio embedder/disembedder products, frame synchronizers, 270MHz video SDI interface development, PLL development, and pipelined digital video processing in FPGA's and other DSP IC's.



Grass Valley Group

• United States

• Senior Design Engineer

  • 1989 - 1994

  As a Senior Design Engineer, I developed video ADC, DAC, filter (analog and digital), PLL, and pipelined signal processing hardware for Digital Video Effects and production video switcher products. I created schematics, guided PCB layout, selected part sources, defined test and alignment procedures, and worked with software developers to define access to and control of hardware features to be controlled by software.

Videotelecom Corp. (VTEL)

• Hardware Development Engineer

  • 1988 - 1990

  As a Hardware Development Engineer at Videotelecom, I was involved the development of video I/O subsystems for video compression/decompression systems used for teleconferencing. This requires analog and digital design of composite video digitization, filtering, decoding, encoding, synthesis, annotation(overlay), and switching(routing) circuitry. I used CAD tools(primarily SCHEMA and SCHEMA-PCB) to design the analog and some digital portions of two to eight layer printed circuit boards. I designed antialiasing filters in both analog and digital(FIR) form and gauged their performance with SPICE, HYPERSIGNAL, and other tools. Where application specific devices did not exist to suit my needs, I substituted PLAs, FPGAs(Xilinxes), and other SSI, MSI, and discrete circuitry to achieve my design goals. I wrote diagnostic software in Pascal and C programming languages.



Miletus Associates

• Hardware Development Engineer

  • 1986 - 1988

  My responsibilities at Miletus Associates included original linear and digital circuit design, enhancement and redesign of existing products, design of 1, 2, and 4 layer printed circuit boards, specification of mechanical design aspects affecting electrical performance, and documentation of electronic aspects of products. Specifically, I designed a variety of analog and digital video processing systems utilizing discrete and integrated technology. I also developed analog fiber optic data links implemented with four layer printed circuit boards. In addition, I developed a number of mechanically shuttered video cameras. This required analog design in the way of type two phase locked loops (which controlled DC, PM motors), digital design in the way of control circuitry which provided power-up and shut-down functions and modification of various vacuum tube and solid state video camera designs to provide compatibility with the shutter systems. Erasable Programmable Logic Devices were used to implement traditional digital and analogue replacement functions. I also designed and built automatic iris control systems as well as a component color bar generator. I developed a number of analog/digital systems for time lapse video recording and video tape review. In addition, I developed a number of phase locked loops and interface circuits for other, predominantly digital projects. I also wrote operating guides and service manuals for the products I designed.



Nisus Video, Inc.

• Hardware Development Engineer

  • 1985 - 1986

  My responsibilities at Nisus Video included original linear and digital circuit design, software development, enhancement and redesign of existing products, specification of mechanical design aspects affecting electrical performance, and documentation of electronic aspects of products. Specifically, my work involved the design and development of electronics necessary to implement mechanically shuttered Professional and Industrial video cameras. This required analogue design in the way of type two electromechanical phase locked loops(which controlled DC motors), digital design in the way of control circuitry which quickly reconfigured shuttered video cameras to and from un-shuttered cameras, and modification of various vacuum tube and solid state video camera designs to provide compatibility with the shutter systems.
