Developed C++ Win32 API interactive enumerated and curve function aspheric lens design programs based on differential calculus and refraction principles. Invented new mathematical proofs for deterministic lens calculations using the interactive program to discover roots of eighth-degree (and higher) polynomials.

In-depth study of various software topics, including Linux and Posix network and IPC; BASH and Windows WSH scripting; and fundamental algorithms. Developed Windows and Linux utilities. Formalized project history web standards. Improved touch pointer program in embedded ARM C and Win32 C++.

Developed firmware and hardware for capacitive touch devices with ARM and MIPS CPUs and Android/Linux/Windows touchscreen drivers. Developed Windows program (Win32 GUI with USB-HID driver) with NXP LPC1342-based USB, I2C, SPI data acquisition system to support general touch and gesture algorithm development. Developed original DSP algorithms for multi-term.

Designed and implemented drivers, interface libraries, and multi-lingual (English, European, Chinese, and Japanese) applications (including installers, co-installers, control panels, and property sheets) for USB (HID, isochronous, and vendor-specific) and serial touchscreens for Windows XP, Vista, XP embedded, Tablet PC, and CE. Invented driver-based means.

Designed and implemented (in C++, x86 asm, 68K asm, lex, and yacc) clinical instrument development system, including self-configuring robot network, distributed multi-processing operating system, robot control language with dynamically configurable compiler, Windows-based (Win32 API) interactive debugging system. Windows 9x/NT/2K/XP universal device driver.

Planned and directed software development of the CD3200 hematology analyzer. Developed multi-domain, hierarchical software/firmware version control system using PolyMake as a job control language to automate project rules for programming MC68340, I8051, Pentium, MC6809, and FPGAs in C, Assembler, VHDL, and Palasm. Developed run-time selectable Japanese and.
