Loveland, Colorado, Us

Developed firmware for a variety of water quality instruments such as a chlorine measurement analyzer, chlorine measurement probe, silica analyzer and a bench top controller. Tasks included hardware debug, low level hardware and color VGA display driver firmware and instrument measurement firmware. Code was written in C/C++ and instruments utilized Keil RTX or embedded Linux operating systems. Processors used were ARM, Cortex and PIC. Agile development methodology was used and code underwent static analysis, unit testing and peer code reviews.Wrote C# program to compile scripting language files that were then downloaded to the silica analyzer to control instrument operation. Also wrote C# program to test sensors that connect to the bench top controller for compliance to the controller/sensor interface specification.

Developed embedded firmware and LabVIEW programs for a variety of polarization characterization and measurement instruments based on liquid crystal technology. Firmware was written in "C" for embedded Philips XA-G49 and LPC2138 ARM processors. Used Keil and Tasking development tools.Debugged hardware, performed hardware bringup on new hardware designs. Used scope, embedded test firmware and JTAG debugger to troubleshoot malfunctioning hardware, debug and validate new hardware, and build instrument prototypes using various evaluation boards.Designed and implemented firmware and LabVIEW programs to enable firmware upgrades of field units. PC LabVIEW program interfaced with embedded firmware to download new object file via USB and reprogram flash memory in the unit. Units no longer needed to be returned to factory for reprogramming.Undertook the task of developing the USB firmware for an optics instrument from scratch and with no prior USB experience. Company possessed only the object code and needed the source code recreated. Completed the firmware in three months, less than half the time of the original developer. New firmware transferred data at twice the rate of the original firmware.Rewrote optics instrument firmware from ground up to improve efficiency and speed. On a tight time basis, firmware read data from measurement hardware, processed the data and transferred the data via USB to the host PC running a LabVIEW user interface program. Speed of the instrument increased tenfold, making it more competitive with industry standards and leading to increased sales.

Developed software for the DLT2 tape drive. Software controlled functions such as tape cartridge load/unload, movement to beginning of tape and tape motion during reads and writes.

Developed embedded software for a multi disk RAID data storage system.

Us

Developed software for the Mammoth line of tape drives.

Developed vision software for the next generation tape library which utilized a 2575 pixel by 1 line CCD camera to take pictures of the tape cartridge bar label. Software used the pixel information from several line scans to decode the bar label. Also developed library controller code in Java.Developed tape drive servo software which controlled functions such as tape cartridge load/unload, tape threading, head tracking and tape motion during reads and writes.Developed embedded software for a multi disk RAID data storage system.

Us

Developed servo software for a variety of hard disk drives. All software was written in assembly language and targeted for Intel and TI DSP based platforms.

Charlotte, North Carolina, Us

Developed software for a real-time optical disk data storage and retrieval unit designed to go on the B-2 bomber. Designed, coded and tested software for drive control, seek and read/write functions, and data error detection and correction algorithms. Software was written in Ada.Developed functional and servo software for a variety of flight control systems (AV-8B, QF-106 drone jet, QS-55 drone helicopter and C-17 airlifter). Software was developed in JOVIAL and assembly language. Participated in all phases of software development from high level design to hardware/software integration and system testing.Developed software for the C-17 real-time color graphics display system. Performed Built-in-Test software design, display format design, character/symbol quality improvement and extensive system testing.
