Senior Electrical Engineer
Analytical, innovative electrical engineer with over 25 years in LED lighting, medical electronics, and process control. One who interfaces microcontrollers to the analog world of batteries, sensors, and high-brightness LEDs.
M2007 – 2009 | Senior Product Engineer | The Home Depot| Atlanta, Georgia
The Home Depot, is the third largest retailer in the world, providing $73.5 Billion of commercial and residential products to the North American Market. Home Depot private electrical brands include Husky, Safe Home, Home Hero, Hampton Bay and Commercial Electric.
- Product Development - Developed private brand label products. Evaluated, compared and qualified competitive products to define product characteristics. Managed off shore product development and qualification.
- Project Management - Managed third party pre-purchase qualification testing for hundreds of new products representing millions of dollars in potential revenue. Developed functional specifications, standards and test protocols for global sourcing of sensors, security products, electrical devices, NiMH batteries, tools, heaters, ceiling fans, consumer electronics and lighting fixtures. Insured that imported products were safe, legal and functional.
- Regulatory Compliance - Saved $30 thousand on one lighting program. Reduced test time and cost by eliminating redundant testing and correlating lead testing to existing federal regulations (lead paint, 16 CFR 1303). Managed test protocol development for California Proposition 65 testing of interior lighting fixtures. Enforced conformance to UL1598: Luminaires, UL153 : Portable, UL1993 : CFLs, UL1278: Heaters, NFPA 70.
2002 – 2007 | Electrical Design Engineer | Cooper Lighting |
- Product Development - Planned future product capabilities to reduce future development time. Designed switching power supply based ballasts, battery chargers and inverters. Managed contract and tested 8051 microcontroller firmware development using C and assembly. Developed dual Hand/Man Pedestrian signal for new ITE standard. Built ITE nondestructive transient interference surge tester. Designed and developed 100 watt, 277 Vac lighting inverter using Pb-acid batteries. Specified, tested, corrected and qualified next generation products.
- Optical Development - Established requirements and test methods for qualification of traffic signal lamps and exit signs. Built manual goniometer for accurate ITE photometer measurements. Selected LEDs and LED layout to meet requirements. Verified product compliance before executing third party qualification testing.
- Circuit Design - Designed power electronics & controls, including analysis, bread-boarding and testing. Utilized loop stability analysis, thermal calculations and measurement, HAST, HALT, MTBF, FMEA, DFM and simulation to reduce test failures, improve quality and shorten development time.
- Value Engineering - Generated savings of $90K/year at a production rate of 5K/yr. City of Chicago specifications for exit lights required white light and optical uniformity. Replaced 44 LEDs with four, high brightness surface mount LEDs reducing LED cost to 20% of the original cost. Managed product qualification to meet UL924, NEMA, FCC, and IEC standards.
- Quality Improvement - Improved customer satisfaction by improving product uniformity. Investigated and analyzed field returns and failed product data. Executed product changes and implemented Engineering Change Notices.
- Product Support - Expanded the CooperLED product line into the southwestern region growing the business by 15%. Modified an existing product, tested to ITE photometric and TX DOT goniometric specifications, and then established product manufacturing in China.
- Customer Support - Saved a $750K/yr line of business by satisfying an angry customer. Traffic signal lamps, designed by an outside consultant, were failing at low temperatures. Rented a temperature chamber and duplicated the failure mode. Corrected the design error and modified customer samples to insure quick response time.
1999 – 2002 | Electrical Engineer | Respironics |
- Circuit design - Developed Japanese OEM oxygen concentrator controller, Oxygen conserver and Breathing monitor. Component level hardware designs included PIC microcontroller, onboard AC/DC and DC/DC power supplies, batteries, motor and solenoid valve controls, user interface, serial communications, oxygen, pressure, temperature and flow sensors. Customized low cost commercial components to provide high reliability with increased value.
- Personnel Development - Project completed on time and within budget. Recruited and managed a summer intern. Maintained the project schedule through coaching and mentoring. DC Motor controller performed to scheduled requirements and was presented to upper management.
- Portable Product Development - Extended battery life of an Oxygen Conserver by 80%. Redesigned solenoid control hardware and software. Added manual override capability by modifying solenoid valve. Investigated battery technologies for portable oxygen concentrators. Developed breathing detection algorithms implemented in PIC hardware and C firmware. Prepared documentation for FDA510K submission. Capable in Good Manufacturing Practices (GMP), Design for Test (DFT), and Design for Manufacturing (DFM).
1991 – 1999 | Senior Manufacturing Engineer | Yokogawa Corporation of
- Product Support - Responsible for supporting $40 million in annual Chart Recorder sales. Designed, implemented and maintained automated test equipment using personal computers, Visual Basic and IEEE-488 equipment. Internal consultant for electronic circuit analysis and troubleshooting.
- Product Modification - Expanded recorder market share by 15%. Customized products for niche markets including nuclear safety, OEM, and pharmaceutical sterilization. Designs included Faraday shielding, Man Machine Interface modification, Current to voltage converters, and circuit modification.
- Factory Support - Component source engineer for data acquisition, flow meters, and analytical sensors. Evaluated circuit requirements, located and documented local electronic component sources to support SMT PCB Assembly operations. Corrected printed wiring assembly processes such as fluxing, dip soldering, wave soldering, and component preparation. Established hardware verification and test schedule for CSA and CE standards.
- Value Added Redesign - Redesigned OEM oxygen analyzer system to reduce costs by 40%. System included: Oxygen sensor, PID controller, AC heater controls, isolated current outputs, Thermocouple inputs, LCD, and user interface. System programmed in C, C++, and 8051 assembler.
- Communicator - Technical liaison to Japanese Manufacturing Engineering department. Developed English drawings and specifications for US operations.
