New Research on reversal electric field the law of physic for AI drone electronic warfare weapon

WORK EXPERIENCE:

Teaching and Consultant, OHSU/PSU, Portland, OR, 09/2020-present

Teach statistic courses and teaching assistant for Dr. Fountain manage the large classroom with 296 students. For lecture note and seminar paper access website: www.pdx.edu/~fountair

Network Consultant: LTE experience with Protocol Stack modem software, Digital Signal Processing (DSP) software, LTE RRC, MAC layer software, Debug, and error analysis

Portland State University Statistic Consultant on projects: market research, Web analytics, Healthcare technology, data mining, predictive analytics, fraud detection, and energy efficient

PMIC, Tablet, Phone Validation Test Engineer Intel, Hillsboro, OR 06/2010 to 08/2020

Run validate stress test help designers getting the new products on market before deadline.

PMIC in theory, power consumption: CV^2f for C is load, V^2 is tolerant voltage 3.6v,

and f is switching frequency. Run the test for the clock, switch, regulator, and intrinsic load.

Debug systems when the problems occur after flash Phone and Bios, install driver, and Win

Physician predict,” Moor’s law will run out of fuel at finFET 5nm for devices unable to handle the heat”.

Correlation between test equipment and technology scaling down the dimension size by 0.7nm every 2 years, Photographic Print Image scaled down every 3 years, and probe cables and test equipment need increased the speed for rule of thumb by 3 times faster than product speed.

RF /Medical device Test Engineer, Benchmark Electronic, Beaverton, OR,06/2003 to 05/2010

(Economic slowdown and the company shut down)

Power Supply Technology: linear, switching, variable, coaxial, and RF laser.

Apply technical capability to analyze complex RF assemblies, components, and dielectric material for minimizing the insertion loss, and making suggestion to improve design

RF laser high power supply between 300W to 1,500KW put components on board by hands and manual test; RF laser application couldn’t be done by SMT machines and automation test.

Electrical Safety Rule requires unplug power when assemble/disassemble the component from the systems (note: power down or using circuit breaker is still getting risk if it had defect part).

Experimental: applied thermal techniques cooling down the systems under test and used camera software built into Laptop for capture hot spot with red color that indicated failure. Supported test department on test floor and trained test technicians on test equipment, ICT test, functional test, and fix & philosophy troubleshoot the issue for save time/money at test floor.

Expert user of Cadence/Allegro schematic capture and Allegro PCB Layout design tools providing critical support of field hardware and software over the entire product lifecycle.

Update defects and test procedures on database as daily test plan and yield improvement. Bottom line, it gets the jobs done faster and efficient and kept production line run with minimum of amount down time find the root cause of problem and implement lasting solution.

Apply Lean Six Sigma principle analyze the root cause of problem with 5 key words for Define, Measure, Analyze, Identify, and Control.

ply Engineer Optimization Techniques moved the test equipment from Remand WA site due to shut down and required to install back at Beaverton OR site making everything working.
