Technical Experience

Software Design

Real-time system design: Systemic solutions for latency, predictability, and simultaneity; multiple simultaneous axis control; "Go and Load" interrupt event handling; BSP primitives and drivers; task-switching schemes based on time and priority
Operating system application and internals knowledge: *NIX, Windows, VxWorks, pSOS, C-EXEC, ThreadX, various proprietary schemes; thread management and inter-process data exchange; analysis to eliminate issues such as deadly embrace and priority inversion
Thirty plus years of experience in C/C++; a few accumulated years of Pascal (Delphi), BASIC, PLM, and a smattering of other high-level compiled and interpreted languages
Web applications: REST interface design; web site design and layout; AJAX and other active scripting in PHP, Perl, and Javascript; various CGI server side applications

Control systems: Analog front end to servo control output; D/A & A/D; logic conversions
Bare metal hardware launch with micros in the families of ARM, AVR, X86, MCS-51, etc.
Analog signal processing: Filtration, delays, level conversions, windowed signal passing
Real world-to-micro interfaces: Position, speed, pressure, flow, and other analog sensing; detectors; discriminators; bounce elimination; power drivers (PWM, FM, phase-angle)

Technical writing: Architecture description, design documents, specifications, protocols, product proposals, APIs, manuals, charts and graphs, and everything else nobody wants to do
Mechanical and packaging design (when forced to do so)

Medical systems: Class III patient-intrusive blood separator, Class IIB syringe pump, Nuc Med Gamma camera imaging, analog X-ray, medication delivery
Automation: Vehicle fleet tracking via IP over cellular networks; municipal waste water lift station management; liquid mixing valve (with full motion system); automotive ignition; automotive LED light balancing; nuclear particle analysis; teller machines; coil winding machines; fuel pump monitoring; portable industrial printer controller/database manager
Imaging: Marine video display system central manager; video capture and recording via DirectX and proprietary schemes; astrophysical data acquisition display; Nuc Med medical imaging; phototypesetting
Datacomm: Router REST interface package; video game networking; automated voice message notification via SIP telephony; one-wire, TWI, and other low-level comms; proprietary protocols and links
Process control: Overall process condition monitoring; position and speed controls using PID; programmable machine controllers; counters, timers, etc...
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, and filtering, non-linear sensor amplification for positional controls
