Work Experience

Litton I ndustries 1990- 1997

Manufacturer of Mi li tary Radar Warning Systems

Master Electronics Technician 1990-1993 - testing and t roubleshooting down to a component level

Radar Warning Systems for domestic and foreign Navy and Air Force.

T est Engineer 1993-1995 - Developed and delivered a RF Test System for the German Air Force

r adar warning receiver. Designed system on an Apple McIntosh running LabView 3.1 controlling

several instruments on a GPIB bus including a Spectrum Analyzer, DMM, and power meter. Interfaced

w ith customer and successfully delivered test station to Lit ton affiliate in Freiberg Germany.

Designed software for test system using LabWindows CVI ( C language). This test system had a mil

spec 1553, RS-422 and RS-232 interface. The test station tested the controller for the Hellenic Air

Force radar warning receiver.

Software Engineer 1995-1998 – Designed real t ime embedded software (C++) for the Taiwan

I ndigenous Fighter controller for the Taiwanese Air Force in a multi-threaded environment. Designed

and implemented Chaff f lare dispenser interface along with a built in test to detect system failures

w ithout external equipment.

T erayon 1998-2003

M anufacturer of high speed cable modem and headend using SCDMA technology.

Senior Member of Technical Staff

Responsible for the Cable modem test station. LabView based system with GPIB and serial interface

controlled instruments. The test station came in two platforms one with a proprietary Terayon

headend for the SCDMA modem and the other a Cisco headend for the DOCSIS modem. The test

stations resembled a mini network with the addition of a Spectrum Analyzer to measure Gain, Spurs,

Phase noise, Band Rejection, etc. Also, a BERT analyzer to measure the Upstream signal quality of the

modems. All results were logged to a database and management tools were created for product

monitoring.

Interfaced with manufacturing and successfully delivered test stations to the manufacturing

contractors in Bangkok Thailand and Nagano Japan.

Neuropace 2003-

Manufactures the Responsive Neuro-stimulator (RNS) an implant for epilepsy. The device detects

seizures and then stimulates the area in the brain where the seizure is occurring, stopping the seizure

and returning normal brain activity.

Senior Test Engineer

M igrated VXI test station to PXI platform. The PXI chassis included a scope, analog input and output

card, DIO and a switch multiplexor board. The small footprint of the PXI chassis allowed for a

significant decrease in manufacturing f loor space.

C reated test software using LabView and Teststand to test the RNS final, PCA and component test

levels. This included writing to the RNS registers to setup the device, generating input signals (sine

waves to emulate brain activity), and measuring output signals across external loads with an

oscilloscope or analog input cards. A source meter was also used to measure DC leakage between

electrodes and effectively measure resistance within the device. All results were logged to a SQL

database including calibration data for the devices which was retained permanently.

Designed test fixtures for the PCA and final devices. The PCA board required external load sets,

relays, discrete test points and a communication port routed to a socket for the PCA.

Deigned several test boards using Mentor Graphics Pads schematic capture, these boards included

analog and digital circuits along with switching and load circuits.

C reated all documentation including test specifications, tech reviews, test plans, parts lists and work

i nstructions for various test stations, ensuring compliance with QA and FDA regulations.

Trained manufacturing personnel in the use of the test station. Successfully delivered several test

stations to contract manufactures in Minnesota and Oregon.

Designed and created environmental test for the RNS. Designed two boards, one a multiplexed load set

and the other a multiplexed telemetry (inductive communication) to support environmental testing of

12 RNS at one time.

Developed tests using LabView and Teststand so all the units could be run in one Teststand sequence

w ith the need for operator input at only the beginning and end of the sequence. This software

downloaded all test data to a database and allowed for individual printouts of each units test data.

C reated data mining tools for management and engineering to monitor test results.

Designed test system for the RNS long range telemetry using the Medical Implant Service Band and

2.45 GHz wakeup frequency. This test was necessary to ensure that the onboard Zarlink radio and

supporting circuitry was functional at the PCA and Final levels. This required designing a circuit card

t hat accepted a socket that held the PCA and allowed communication with the Zarlink through a SPI

bus using Aardvark technology. The final level was performed in an RF chamber using an antenna that

b roadcasted the 2.45 GHz wakeup and communicated on the M ICS band. Tests performed: RF

sensitivity, Power Tuning, adjacent channel power, unwanted emissions and spurs. Developed all tests

using LabView and Teststand.
