Robotic Hematology Analyzer -- Key developer on a small software team that helped take Bloodhound, an automated hematology analyzer, from its startup / early prototype phase, through several full release cycles, through a successful acquisition by Roche. See https://www.youtube.com/watch?v=T25tnzMR6FcDirectly involved in all aspects of design, coding, and testing activities for the server and embedded side of the multithreaded PC-hosted machine control, patient sample processing, and workflow management systems. Java / C++ / OpenCV, SQL, SVN, DOORS, Mantis, Linux.OpenCV algorithm development, including specification and design of various OTS and custom camera, optics, and illumination systems for "LevelSense" (submicron accuracy microscope slide surface detection) and "Rack Imager" (test tube location detection and OCR).

Robotic Semiconductor Wafer Handling System -- Sole architect, designer, and implementer of "JSAL-RCS", a PC-hosted HMI, supervisory, robot motion planning, and motion control system for a 5 axis SCARA robot and high vacuum control hardware. C#,C++/CLI, .NET, MEI motion control. Hardware under control included BlueShift-developed 5-axis dual arm SCARA wafer handling robot, 4- and 6-port vacuum chamber modules, wafer cassette elevator, and vacuum load port.This was a 4-tier dynamically configured/loaded system, including visualization and full offline simulation capabilities of all modules. Went from a design proposal to controlling a working prototype wafer fabrication system in 5 months.Successfully deployed to domestic research production facilities on time, meeting or exceeding all performance and reliability requirements.Deployed this control sytem and JSAL-designed retrofit hardware and fixturing to a working Canon-Anelva wafer fabrication line in Japan as a retrofit to an existing (orphaned, underperforming) legacy installation. Notably for this industry, the hardware/software retrofit was customer installed, with the commissioning and startup accomplished entirely remotely by JSAL and myself, without a single site visit.

Robotic Semiconductor Wafer Handling System -- Proposed and accomplished a complete refactor/recode of the robot motion control layer of BlueShift’s 5-axis dual-arm SCARA semiconductor wafer handling robot and vacuum chamber product. Windows / PC-hosted multithreaded C#/C++, with MEI SyncNet servo motion control. Recode fixed all outstanding critical performance issues and bugs, and met business needs by handling arbitrary robot configurations, vs. the original system’s hardcoded configuration. The completed software was less than half the size of the original. It was deployed for new systems and as an upgrade directly into working wafer fabrication facilities with zero reported defects.Designed and implemented the IO, robot control, and supervisory control layers for a next-generation C#/.NET-based semiconductor manufacturing supervisory control platform. Developed C++/CLI .NET framework that layered BlueShift’s C++ motion control code (see above) under a .NET OO machine control hierarchy.Designed and developed C# framework that provided a dynamically loaded machine model that included extensibility for integration of third-party hardware inline with Blueshift’s products. The supervisory control system handled scheduling, product tracking, resource contention, and mechanical interference avoidance for entire wafer fabrication lines. RCS recruited and supplied the key personnel for this project, which was successfully deployed on schedule, straight into three working semiconductor foundries in the far east.

Designed, co-developed, and managed a two-man independent team, to produce “Leaf DCBIII/Live for WinNT, With ColorShop. This was a port/rewrite of Leaf's Mac application to control a 6 megapixel studio CCD digital camera, and a post-processing suite similar to something like PhotoShop of that era. Coded the multithreaded I/O engine, the file I/O, the camera control and device interface (including device driver design and debugging), recoding the image processing routines for reentrancy and improved performance, and about 20% of the GUI. (VC++5.0, MFC4.0, SKD, DDK, WinNT).

Refactored and ported a large (180,000 lines of C/C++) digital printing and color-management application. Advised the original developers on C++ and OO techniques and coding practices. The refactoring eliminated approximately 24,000 lines of code and over 150 documented anomalies. (C++, Mac PPC / OS 7, CodeWarrior)

OO architect and key developer of Printasia, a Digital Photofinishing Kiosk. The product included custom interfaces to flatbed and film scanners, powerful image enhancement and manipulation features, page layout, and network printing.

This was a side project of the Terminal Doppler Weather Radar (TDWR) development effort led by Lincoln Labs; unlike TDWR, this ground control station intentionally directed a NASA instrumented 737 aircraft INTO severe weather to gather in-situ measurements of windshear, related atmospheric data, and its impact on the aircraft.Additional responsibilities included post-flight data analysis of both the NASA flights and other research missions, windshear and storm prediction algorithm development, and co-authoring a research paper describing the efficacy of on-board versus ground-based estimates of windshear hazard.

Created automated high-volume automated battery QC final test machines for the company’s flat-pack battery assembly line. Specified and debugged much of the project's mechanical and electronic hardware, and wrote all software. Designed and supervised the QC acceptance test for the completed system (IBM PC, MSDOS, C, MASM).Designed a new statistical method for battery QC testing and acceptance. Adapted the production QC hardware to perform these tests, and designed a long-term experiment to test the proposed technique.
