Computer-Integrated Surgical Systems and Technology

Douglas Green, Dean of the College of Engineering, Marquette University

With the advent of more reliable and capable computer and robotic technology, future surgeons will be provided with tools to carry out surgical interventions more accurately and less invasively. Computer-integrated surgical systems will in-corporate patient specific models, based on a full integration of all pre-operative laboratory tests and imaging information about each patient. A number of examples will be drawn from the NSF Engineering Research Center in Computer Integrated Surgical Systems and Technology. As the director of that center, Russell H. Taylor said, "Computer-integrated surgical systems will have the same effect on health care in the next 20 years that computer-integrated manufacturing had on industrial production over the past 20 years, and, for many of the same reasons. By integrating information with action, these systems will lead to critical advances both in the quality of surgical treatment and in its cost effectiveness."

Green is the Dean of the College of Engineering at Marquette University, a native of Big Spring, Texas, and previously had been Associate Dean for Research at the Whiting School of Engineering at Johns Hopkins University in Baltimore, MD from 1993-1999. Before this, he was professor of electrical engineering, Associate Dean for Research and External Affairs, and Director of the Center for Research in Engineering and Advanced Technology (1988 to 1993) at the Thomas J. Watson School of Engineering and Applied Science of the State University of New York at Binghamton. From 1985 to 1988, he headed the Computer and Information Department at the Research and Development Center of Dowell Schlumberger in Tulsa, Oklahoma. Green was a member of the Electrical Engineering Department faculty at Texas A&M University from 1978 to 1985, and from 1984 to 1985 he served as coordinator of computing at the Office of the Provost. He presently serves on the Board of Directors of the American Society of Engineering Education and is Chair of its Engineering Research Council. Green is also the President of Tau Beta Pi Association, the national engineering honor society.

The Loading of Free Wheel Diodes (FWD) and IGBT's In Power Modules

Richard Lukaszewski, Standard Drives Development, Rockwell Automation - Allen Bradley

The loading of free wheel diodes (FWD) and IGBTs in the power modules of a Voltage Source Converter (VSC) are in-vestigated. In converter duty, the FWD is utilized more then the IGBT. Presently, most FWD's in power modules are op-timized for inverter duty. This practice tends to undersize the FWD from a converter viewpoint. This design philosophy is examined in the paper. For this purpose, the original dynamic thermal model of IGBT and FWD were developed. Model parameters were identified from the manufacturers catalogue data. A mathematical model of the entire VSC was developed to compute current, voltage, power and thermal conditions for the power module and other components in converter operation.

Rich Lukaszewski graduated from Milwaukee School of Engineering with a BSEE in February of 1976 and is a Registered Professional Engineer in the State of Wisconsin. He was employed at Louis Allis/Magnetek for sixteen years. During his stay at Louis Allis, he worked in Drive Systems Engineering and later in Drive Development Engineering. At Louis Allis, he worked on SCR based current source inverters, BI-polar, and IGBT voltage source inverters. Since 1992 Rich has been employed by Rockwell Automation / Allen-Bradley, Standard Drives Division in Mequon, Wisconsin, where he is a Senior Project Engineer-Hardware. Rich was the Project Engineer on the 60 to 125 Hp frames used in the current Bulletin 1336 product line. Presently, he is one of the project engineers on a new drive development program that covers a wide horse-power range. Rich has been an active member of the IEEE/IAS and is involved with several committees within the IAS. He is active in the Industrial drives committee and is current the Vice chairman for the Power devices and Components Committee. Rich served in the Milwaukee Chapter if the IEEE/IAS Section from 1980 to 1984. He was the Section Chairman of the Milwaukee Chapter when it won the "Best Large Chapter" Award presented at the 1984 IEEE/IAS Annual meeting in Chicago, IL. He is also the co-author of several technical papers presented at IAS Conferences.

Modeling and Implementation of DSP FPGA Solutions

Robert D. Turney, Chris Dick, David B. Parlour, and James Hwang, Xilinx Inc.

Recent developments in the simulation capabilities of high level mathematical modeling tools have opened exciting new design flow possibilities. System level support for bit true modeling enables a designer to use a single environment to create floating and fixed-point models, and to make scaling and rounding decisions early in the design process. At the same time, FPGA vendors have expanded commercial IP offerings to incorporate higher level DSP functions. Together, these technologies enable a new flow for data path design that includes design iterations at the system level. In the past, DSP FPGA design required the combined efforts of a DSP engineer and a hardware engineer familiar with HDL or schematic based design. In this workshop we present a new method to derive a HDL netlist for a data path directly from a system level tool. The steps include construction of an ideal mathematical model, investigation of implementation effects, test-bench creation, and hardware netlist generation. Traditional HDL design methods are then used to complete the design implementation. These concepts are illustrated through examples of digital filter realizations and Discrete Wavelet Transforms (DWT).

Robert Turney is a Senior Systems Engineer in the CORE Solutions Group at Xilinx, specializing in image and video processing algorithms. He also holds a lecturer position at the University of Wisconsin and Milwaukee School of Engineering teaching DSP and VLSI related courses. He has been involved in medical image processing since 1994 in projects such as real-time lossless compression, image enhancement, and noise reduction for real-time image acquisition. He received his BSEE, MSEE from the University of Wisconsin where he is currently a PHD candidate.

EMC Chapter

Comparison between Two Vantage Points: The EMC of Electronic Design vs. Successful Electronic Design without Neglecting the Importance of EMC.

Mr. Matt Planning, RF Design Engineer, L.S. Research Inc.

While working in EMC research in the automotive sector, the electromagnetic compatibility of system and sub-system electronics relative to limits defined by industry-recognized documentation was my primary objective. Others had already performed the functional design in the engineering department. Now in the high-tech engineering sector, I am involved in circuit design and development. The EMC considerations still exist, as with any circuit design, but they are something I can better anticipate, having spent the time involved in EMC research. I will share with the audience some experiences from my time as an EMC technician, and how they relate to my current position as a RF focused design engineer.

For nearly three years prior to receiving his BSEE from the University of Wisconsin, Milwaukee, Matt worked at Harley-Davidson in the Electrical & Electronic Systems Group. During that time, he was an integral part of the development of the Group's in-house Electromagnetic Compatibility Lab. He also evaluated a microcontroller based, high-performance fuel injection system, developed effective ignition noise reduction strategies and tested prototype instrumentation and cruise control systems. In 1999, Matt was awarded an U.S. Patent for developments in 1996 on motorcycle cruise control systems. Matt joined L.S. Research in February 1998 as a RF Design Engineer developing antennas and communications circuitry.

In his spare time, Matt is an active Amateur Radio Operator (a Ham, per se) who enjoys building antennas, analog and digital circuits and restoring vintage Test and Measurement equipment. He is also serving as First VP for the Milwaukee Radio Amateurs Club. When not involved with electronics, Matt tinkers with his collection of Pontiacs from the 1960s.
