1990 – 1994 Harvest Software, Sunnyvale, CA
Senior Software Engineer
Harvest Software developed an automated order entry system using fax as an input device. My primary responsibility involved extracting data from the fax image (document recognition). This process took advantage of image processing and computer vision techniques such as bar code processing, skew detection and correction, line extraction and image decoding and encoding. The application ran on a Unix based system and written in C,C++.
1987 -1990 Loma Linda University Medical Center, Loma Linda, CA
Senior Software Engineer
This project involved the development of a treatment planning system for a Monoclonal Anti-body cancer research project. I was responsible for two main areas of the program. The first area was a system that automatically outlines particular tissues on a CT Image. The second area was a system that registers a CT image and a Nuclear Medicine image. The registration process involved the development of methods to physically align a patient in both a CT imager and a NM camera along with special image processing algorithms. Both of these programs were used to speed up the dosimetry calculations. Algorithm testing was done on a PIXAR Image computer and then ported to both sun and Dec workstations
1984 -1987 Rockwell International, Anaheim, CA
Software Engineer
There were two projects I was involved in at Rockwell, both involved real-time, multiprocessor navigation systems. The first project was the maintenance of the ESGN navigation system. The second was research for a ring laser gyro system for commercial navigation systems. Both systems used three Motorola 68xxx processors on proprietary hardware. I was responsible for all software, system BIOS and application software.
These systems were very time critical and what would be considered “hard real time”. The processing was driven by interrupts from the gyro processing hardware. Any delay in the processing would render the navigation calculations useless. The software was all assembly code.
