I am a supervision, control, test and measurement specialist. I develop several  systems:

visual inspection automation, tests production sequencer, instruments drivers, automatized and semi-automatized test and measurement benches, instrumentation (National Instruments, Racal, HP, Agilent, Rodhe & Schwartz...).

My strong competence in the field of test and measurement has led me to participate in various projects of:

aeronautics, automotive, armament, food, petrochemicals, energy, electricity, telecoms, construction, scientific research, pharmacology, cosmetology.

LabVIEW is used in this system to program a supervisor controlling the quality of sand in a career, before filling the trucks after the results of measurements of quality, we will inject a product to improve the characteristics of the sand to neutralize impurities (such as clay for example) and make them suitable for building. This pilot supervises three PLC (programmable logic controller), which each have a dedicated function: a sampler, a analyser and a divider. Software for the supervising of the sand quality control Programmable logic controller

The role of this test bench is the analysis and quality control of gas cylinders used in metallurgical industries, chemical, petrochemical, pharmaceutical and food industry. The control system of gas is functionally decomposed as follows: Entering management and production information of gas Measuring the gases composition, Analysis of measures and results, Archiving data to a remote database. The bench contains the following elements: Gas delivery system, Measurement instrumentation, Acquisition and control central, Management and supervision software. User interface of the supervision software for the gaz analysis bench

The aim of this test bench is to validate electronic measurements and audio signals. The system must be enough flexible to permit the test of several models of car radio.

Radio car validation bench

Calibration system for oil well sensors. This system measures the pressure and the temperature behavior of the sensors along one week to one month. All measurements are safeguarded in a data base to be analyzed and to create reports/ratios.

Electronic Control Modules are subsystems consisting of CPUs and assorted signal inputs and outputs dedicated to controlling a component within the vehicle (cars, trucks...). The aim of this system is to check that all ECM actions are correct, conforming to the specifications. It performs design validation. It is a development bench, helping technicians and developers during design and developement phases. System Diagram
