Technical Experience

Software Design

• Over fifteen years of experience in C/C++; a few accumulated years of Pascal (Delphi), BASIC, PLM, and a smattering of other high-level languages
• Several years of cumulative experience in assembly with micros such as 68000 family, 80X86 family, 6800 family, MCS-51 and derivatives, Z80, etc.
• Real-time system design: event- and time-driven interrupt handlers, device drivers, task-switching schemes based on time and priority
• Operating system application and internals knowledge: UNIX, Windows, MS-DOS, VxWorks, C-EXECUTIVE, ThreadX, VMS, various proprietary schemes
• Web applications: web site design and layout, PHP, Perl, and CGI server side applications for SQL data management; client-side Javascript applications

Electronic Design

• Control systems: (analog front end to servo control output): D/A and A/D; logic conversions
• Analog signal processing: filtration, delays, level conversions, windowed signal passing
• Real world-to-micro interfaces: detectors, discriminators, power drivers (PWM, FM, phase-angle)

Collateral material development

• Technical writing: design documents, specifications, protocols, product proposals, APIs, manuals, and all the rest of the writing nobody else wants to do
• Mechanical and packaging design (when forced to do so)

Technology Background

Current

• Medical systems: Class III patient-intrusive blood separator, Class IIB syringe pump, Nuc Med Gamma camera imaging, analog X-ray, medication delivery
• Data communications: TCP/IP network, DDS, modem, proprietary formats and link layers
• Process control: programmable machine controllers, counters, timers, position and speed controls using PID
• Sundry: video capture and recording via DirectX; astrophysical data acquisition display subsystem, phototypesetting imaging, automotive ignition, nuclear particle analysis, teller machines, coil winding machines, fuel pump monitoring, video game networking, portable industrial printer controller/data transfer/database manager

Legacy

• Positional sensors and servomechanisms
• Telephone/intercom
• Resistive welding
• Telecomm mainframe switching systems
• Agricultural equipment instrumentation
• Audio mixing, VCA level control, filtering, power amplification
• Wave shaping and level shifting for instrumentation
• Telecomm and datacomm wave shaping, delays, filtering, etc.
• Non-linear sensor amplification for positional controls
