My activities in 2013

During the year 2013 the missions of measuring and testing took me in France, Mexico, Brazil, Tunisia, Canada and the United States. They allowed me to increase my experience in the integration of test benches in the mass production lines and test systems technical audit. And it's always a pleasure to meet various stakeholders, engineers and management teams from different sectors, different countries and communicate in different languages ​​(English, French, Spanish and Portuguese).
Here's the list of my activities in 2013:
  • Testing process audit into a xDSL modem repair center, defining solutions to establish, develop the new process, the layout of the line. This optimization resulted in an increase of 500% test volume capacity (TestStand ).
  • Accessory on a regulation system of laser cooling with cRIO LabVIEW real-time.
  • Development of a quality test bench at the end of the mass production of xDSL modem (GVT, Telefonica): VDSL, WiFi 2.4GHz, 5GHz WiFi, FTTH, Ethernet, HPNA (TestStand).
  • Optimization and debugging of functional test benches in the mass production of xDSL modem: 40% reduction in test time, reducing false failures (TestStand, LabWindows / CVI)
  • Development of instrument drivers for the measurement of the skin characteristics with LabVIEW.
  • IVI drivers development with LabWindow/CVI integrated in TestStand.
  • Development of a system for measuring the aging of electronic components
  • Trainings of LabVIEW, LabWindows/CVI, Measurement and instrumentation with Visual Basic. Net (Measurement Studio)
  • Technical audit of test benches and power supplies in xDSL modems repair centers (GVT, Bell and Cablevision) to increase testability and volumes: analysis of the feasibility of testing, measurements stability, statistical analysis of the measurements and production data for test benches, optimization of operator actions, software, traceability and product flows.

Increasing testability

For this project, my client asked me to increase the capacity of their test suites for your after-sales service: going from 500 units daily to 2500 units per day (units here are modems ADSL / VDSL telephone, HPNA, WIFI , WAN, Ethernet and USB.) Using benchmarks aftermarket in this case is to analyse and give a diagnosis to replace defective components and then verify that the repair has solved the problem.
Analysis
To optimize the test suites in the best way, the analysis is essential to decide what to do I found several factors that limited the ability.:
  • too many manual actions: the test is unfair, well, whenever operator intervention The can not perform actions on another bank.
  • b ank usability testing: the operator loses time to place the unit, connect and disconnect.
  • software usability testing: test results are not clearly identifiable, the operator loses time to read the diagnosis, or worse, think again.
  • false failures: if false failures, operator definitely test and the test is restarted, we lose time. False failures They can be caused by hardware (measurement instability due to instrumentation wiring, connectors or other components) and software (processing measurement, analysis, tolerance).
  • the use of hardware resources: all tests are run one after the other, while some can run in parallel on the same drive or multiple drives.
  • process: having a single bank, to execute all actions and testing is not always the best solution. The number and functions of banks depend on the product, the tests to be performed, the environment and why we test.
  • optimization of the line: the placement of the test suites may penalize the flow, forcing the operator to waste time in their movement and increase the risk of handling errors that may damage the product.
  • traceability: having the product history is important to optimize the repair, fluidize (not try a product that has been tested failed previous tester without any repair), diagnose problems l test Provide maintenance actions, but also to analyze production.
Solution
After presenting an analysis of the identification of problems, I worked with my client on several points:
  • Review of the line and testers to improve the flow, ergonomics and movement of operators and products.
  • use of the material now available, replacing and adding new, rewiring and connector type for better reliability and speed.
  • l migration software testing from test scripts executed from the Linux command line to test sequences of TestStand on Windows by creating a simple screen (test in progress, good or bad result, pending test) to test parallelization to reduce the time.
  • test report generation, data centralization in the network and development of data analysis software.
  • operator training and actions optimization.

My activities in 2012

The projects were exciting for 2012. Anyway I did 160 000 km by plane to see my clients: going a week in a country, 3 weeks in this one, 2 weeks in this city, but in total it is 6 months of business trips to share techniques and friendships (behind the technique there is always the human). This year I enjoyed sharing my experience, working beyond my expertise to give the best to support my clients in difficulties, improving processes at the level of software and hardware and analysing the procedures to propose changes to solve the problems, speak four languages ​​at the same session (English, French, Portuguese and Spanish), share my experiences in these languages ​​during training.
Here is the summary of 2012:
  • test bench development with TestStand and LabWindows/CVI for Brazilian industry; install production lines, improve testing procedures to reduce cycle time and increase capacity
  • production equipment support: traveling or remote support for the identification of the issues, or pre correction and optimization analysis to get the right specialist (for production database for example)
  • trainings LabVIEW, TestStand and LabWindows/CVI
  • development of a measurement system for the cosmetic industry with LabVIEW
  • test bench development to validate the communication protocols for the production of PLCs with LabWindows/CVI and TestStand

My activities in 2011

To start the year 2012 nothing better than to do the recap of last year 2011 as an independent engineer:
  • Trainer for LabVIEW, TestStand and LabWindows/CVI for various sectors of industrial, scientific and military activities.
  • Development of a system of eddy current measurement for detecting surface defects of the materials for nuclear plant (LabWindows/CVI).
  • Technical intervention to improve cosmetology and pharmacology clinical study system (LabVIEW)
  • Improvement of a thermodynamic principles bench study applied to refrigeration (LabVIEW real-time and embedded WEB server)
  • Implementation of Modbus-TCP instruments measurements on Ethernet network and radio for the analysis of energy consumption in buildings and industrial installations (LabVIEW and Visual Basic)
  • Development of an automated transcoding measurements server for PLC (LabVIEW)
  • Implementation of functional tests for speed industrial controllers validation (TestStand and LabWindows/CVI)
  • Conference titled "Particle accelerator: light to future medical" featuring advanced technology through nanoparticles observations processed by synchrotrons.

Conference "Synchrotron: lights to medical future"

This time, the conference was not about control and measurement with LabVIEW, LabWindows/CVI or TestStand but on particle accelerators in medicine for the treatment of cancer and especially the applications of synchrotron radiation to observe proteins and different mechanisms operating at the end of active use in future nanotechnology based drugs. Where does the idea of ​​this issue? I play accessory to give synchrotron "Soleil", south of Paris, operated by the CNRS (French National Center of Scientific Research) and the CEA (atomic energy commission) to optimize measurements in a beam line.
