Sensata (formerly Dimensions) designs and manufactures power (3600 watts) conversion systems including power inverters (DC->AC), power DC->DC converters, and chargers for various battery types including Lithium-Ion. Their main customers are utility companies such as Excel, high end Recreation Vehicle manufacturers (using Lithium-Ion), and the government which uses high power 3-phase inverters.My responsibilities include writing (embedded) firmware (C language) to make the devices work.The custom hardware platform uses a Microchip dsPIC33F as the brain.Low level programming requires interfacing to hardware i/o and chips including1) Non-Volatile-Memory flash chip2) Analog/Digital converters to read voltages, current sensor currents, 110 volt A/C line3) Timers, Temperature sensors4) Digital I/O for reading user buttons and switches5) Cooling fan control (PWM) to reduce operating temperatures6) SPI bus to interface to a remote LCD controller7) Watch-dog-timer (7 msec)8) Controller Area Network (CAN bus) implementing the RV-C (Recreation-Vehicle-Communications) protocol which is an off-shoot of the J1939 protocol.9) Power train uses an H-Bridge transformer that is regulated by controlling 4 corner Field-Effect-Transistors (FETs) at a rate of 23 kilohertz.10) Charging uses fly-back transformer induction to produce voltages larger than available from the original power source to allow charging.11) Many of the hardware interfaces are interrupt driven, including PWMing the duty cycle of the FETs at 23 khz to produce a pure-sine wave inverter 110 VAC output signal.Also wrote PC based software automated mfg tester to test units on the production line. Written in C# and uses a scripting language which allows engineers to develop test scripts for testing different models. USB devices interfaced to include:DC,AC power supplies, electronic DC loads, A/D units, DMM, Hi-Potential testerFirmware Programmer device, Multi-channel relay units, CAN bus, RMS, THD

Designed and wrote the flight control firmware for a NASA science satellite called Firefly which was launched Nov 19, 2013. It is a small CubeSat satellite (size of a loaf of bread) which orbits the earth every 90 minutes, and includes instrumentation to detect gamma ray particles emitted during lightning storms. It communicates with ground station, located at Wallops, VA, over a 400Mhz radio transceiver. It is powered by solar cells and has battery storage during eclipse. It uses a Texas Instruments MSP430 processor for the flight computer and was progammed using IAR development system using C language. All of the low level hardware i/o interfaces were written from scratch.I also wrote the MFC C++ ground software for communicating with the satellite, which used a custom binary protocol for communicating with the spacecraft via the 400Mhz packet radio transceiver. The spacecraft orbits so fast that we had to account for the doppler shift of the radio waves.First ground contact was made Jan 6, 2014. The mission is funded by the National Science Foundation.Here is a link to replay the NASA Firefly rocket launch on Nov 19, 2013.https://www.youtube.com/watch?v=5fF8f4FUrkA Links to the project mission:http://www.spacedaily.com/reports/NASA_led_Firefly_Mission_to_Study_Lightning_999.htmlhttp://mstl.atl.calpoly.edu/~bklofas/NSF_comm/20091130_telecon/Firefly_Status_Nov_30_2009.pdfhttps://www.youtube.com/watch?v=_ZHVA36gqMMhttp://firefly.gsfc.nasa.gov/http://www.nasa.gov/topics/universe/features/firefly.html

Designed and wrote firmware for a wireless animal implant medical device using ThreadX and Digi Arm9 module. Worked on the wireless implant (embedded) firmware which uses a MSP430-F5 processor with the IAR development environment and C++ language. Also wrote code for the PC LabView based manufacturing test system DLL interface which used C# .NET VS 2008/2010 and communicated with the wireless implant device.http://www.datasci.com/

Spectrum Design Solutions (now named Etherios) is a design services company with a focus on solving customer's wireless development challenges. They employ over 30 highly specialized engineers with extensive experience in wireless technologies. In July 2008, they were acquired by Digi International. Projects worked on include: 1) Wireless animal implant moitoring system using ThreadX RTOS; ARM9 processor / Cygwin; RMTrack used for requirements tracking (C++)2) 14 channel RFID Reader incorporating ARM7 processor (RC632 RFID chip) ThreadX RTOS; Eclipse / GNU X-Tools development environment (C++)3) Wireless golf-cart GPS tracking system; BusyBox embedded Linux; Freescale processor (written in C)4) Wireless Industrial Telematics controller; CAN, GPS; GSM; Linux (RedHat) (written in C)5) Automotive anti-theft device; PIC24F; GPS; GSM Wireless; Microchip ICD3 ICE (written in C)6) Ported Windows CE 5.0 FlashFX device driver; Platform Builder 5.0 (written in C)7) Medical hygiene compliance system PIC18F; Zigbee (written in C)http://www.spectrumdsi.com/

Sr Embedded Firmware Engineer developing electronic controls for Caterpillar, John Deere, Bobcat, and other industrial manufacturers.http://www.deltatechcontrols.com/

As a contract consultant, I wrote a Windows CE 5.0 USB Device Driver for Purdue University Forensics lab.http://www.itrgroupinc.com/Home.aspx

I was part of a cross-functional development team providing roadmap enhancements to the solder paste laser inspection machine. My main responsibilities included firmware enhancements to the QNX real-time motion-control / data acquisition / image-processing sub-system (written in C), but I was also assigned the task of converting the Windows MFC code from .NET 2003 to .NET 2005. This was a large software system with over a million lines of code.http://www.cyberoptics.com/

Gentra Systems is a small biotech company which designs and manufactures DNA/RNA purification systems and has since been purchased by QiaGen (QGEN). I was responsible for architecting and implementing the firmware for their new table top model. The firmware for the custom hardware was was written in C, and required low level programming (CAN bus, I2C, motion control, sensors). Safety requirements included properly handling of bio-hazard material, and flammable reagent chemicals. I also wrote a couple of Windows MFC C++programs for communicating with the instrument and burning flash memory.http://www1.qiagen.com/

Imation was a spin-off of 3M and makes data storage products.I was in the "Systems Lab" group which developed hardware/software test systems for research of magnetic recording media, including magnetic tape and rotating disk media. I was involved with motion control components, reading/writing components of digital media, and magnetic coating analysis components.Most of the software was written in “C” on custom PC-104 hardware platforms. Various motion controllers were used such as Galil and Tech80. http://www.imation.com/

Software Architect and Technical Lead of the high-end commercial video-board control system. The video-board is a matrix of LEDs that operates as a large screen “video” board. This control system displayed stats at the Lillehammer, Barcelona, Atlanta, and Sydney Olympic events. It is also used in several sports stadiums around the country/world, including the Metrodome, Montreal Expos, Seattle Mariners, and the Xcel Energy Center.The controller was a PC based computer with custom hardware that interfaced to the matrix board. The software was written in "C" and was heavily interrupt driven. The software ran under the MS-DOS operating system and then later ran under Windows NT. Several routines were written in x86 assembly language for speed.http://www.daktronics.com/

I wrote Fortran programs for in-house customers on an IBM 370/3033 mainframe running VM/CMS. Projects included: Designing / writing CAD software to model complex 3D parts such as turbine blades and vanes using cubic splines and generate NC tapes for machining parts Developing a software tool to “unwrap” a 3D airfoil to a 2D flat pattern for manufacturing airfoil baffles from sheet metal. This involved using calculus, least-squares-sums, Newton-Raphson iteration for root searching, and math libraries for matrix inversion. Software support for various departments including Tool Design, Manufacturing, Drafting, and Inspection. Technical support for the Evans & Sutherland real-time system used by engineers for viewing 3D models of airfoils.http://www.pw.utc.com/
