EXPERIENCE

Jiskha Homework Help Online Physics & Mathematics Tutor

Southfield, Michigan June 2000 – Present

-Online tutor at www.jiskha.com

-Tutor elementary through college students in mathematics and physics

-Have resolved over 13,000 mathematics and science problems

FORD MOTOR COMPANY Reliability Engineer, Contract

Dearborn, Michigan January 1992 - June 2000

-Performed reliability assessments/predictions and worst case circuit analysis on Electronic Modules including

Electronic Engine Controls and Antilock Braking Systems. Excel 5.0 spreadsheets and SAS were used with the

AT&T/Bellcore Reliability Prediction Method.

-Each module was broken down into functions and the failure rate of each function was calculated at selected

temperatures ranging from -55 C to 85 C

-Wrote reports showing the results of each reliability assessment/prediction including recommendations for

Improving reliability. Held meetings with system and design engineers to discuss reliability issues

AC ROCHESTER Electronics Design Engineer, Contract

General Motors Corporation - Flint, Michigan March 1989 - March 1990

-Analog circuit design for new Fuel Level Sender concept. Designed analog circuitry to interface with pressure sensors

-Tested Fuel Level Sender over a temperature range of -40 C to +85 C

-Wrote monthly progress reports

GENERAL DYNAMICS CORPORATION Electronics Design Engineer, Contract

Land Systems Division - Warren, Michigan January 1982 - July 1988

-Analog/digital circuit design for Fire Control Electronics Unit, XKI Tank Program. Designed: Synchronous

demodulators Azimuth and Elevation Rate Amplifiers, power and scaling amplifiers; a LED driver to vary

current over a range of 0 to 600 milliamperes; a mile per hour to DC converter to produce a DC output

proportional to vehicle speed.

-Tested and operated all circuits over a temperature range of -40 C to +75 C. Wrote test procedures for Fire

Control Electronic Unit and its circuit cards; and designed test equipment for bench testing of F.C.E.U. circuit cards.

-Redesigned Fire Control Electronics Unit (F.C.E.U.) reducing number of circuit cards from nine (9) to six (6).

Improved circuit performance and accuracy by reducing number of stages in each demodulator.

-Performed open bench test of F.C.E.U. and its circuit cards. Designed test set for production testing of F.C.E.U.

-Followed all designs from concept to production, assisting subcontractor in solving initial production problems.

Assisted in troubleshooting production F.C.E.U.s and circuit cards.

GMC TRUCK & COACH DIVISION Project Engineer

Pontiac, Michigan July 1977 - December 1981

-Designed and developed a battery blower sensor and shutoff system, for use in all propel battery charges

Responsible for fabrication and installation

-Designed special harness which allowed SIGNAL and STOP lamps on a disabled vehicle to be controlled from a

towing vehicle

-Designed and developed a battery current sensing system to detect battery current “RUNAWAY” during charge - sensor

would shut-off battery charger when “RUNAWAY” condition existed. This self-testing safety device required the use of

more than 100 solid-state devices including ICs.

-Assisted in design of a microcomputer based battery charger controller. Designed the front end of controller, which

included a current integrator and scaling amplifier, and a regulated power supply for the controller. Power supply included

current limiting and current fold-back for short-circuit protection.

-Wrote test and calibration procedures for integrator, scaling amplifier and power supply

CINCINNATI ELECTRONICS CORPORATION Electronics Engineer

Infrared and Radar Department - Cincinnati, Ohio January 1974 - July 1977

-Design and development of regulated power supplies at output levels up to 100 watts at current levels up to 20 amperes

with temperature coefficients less than 1MV/ C over a temperature range of -55 C to +75 C

-Designed power control system for Infrared Laser Ranger System

AVCO PRECISION PRODUCTS DIVISION Electronics Engineer

Weapons Electronics Department - Richmond, Indiana July 1966 - January 1974

-Circuit design, development and test of microwave an optical fuzing systems

-Assisted in design of a 15 GHz radar fuzing system and designed gate range cut off and modulator circuits

-Performed laboratory and field tests on radar systems, made attenuation measurements on PIN modulators at frequencies

Up to 4 GHZ and specified microwave components

-Designed wideband amplifiers for short pulse receivers and high speed modulators for injection laser diodes - modulators

operated at PRFs up to 50-KHz with pulse widths as short as 20 nanoseconds

-Designed and developed an RF receiver for a pneumatic tire low pressure monitoring and warning system

-Designed D.C. - D.C. converts for optical fuzing systems and sawtooth and triangular wave generators for FM-CW fuze
