The fuses and relays box test bench has two functions in trucks assembly factory:

it displays to the operator the optional fuses and relays to be manually inserted according to the serial number of the truck it inspects the box by vision checking all standard and optional fuses and relays are in place

This software does the automation the characterization measurements of the skin during clinical trials of pharmaceuticals and cosmetics, using more than 15 instruments usually present in this type of laboratory: corneometer, sebometer, pH-meter, thermometer, glossimeter, mexameter, colorimeter tewemeter, reviscometer, spectrocolormeter, chromameter, cutometer, torquemeter. Therefore, it makes quicker measurement through a single software tool.

This system allows the study of refrigeration systems and the implementation of the thermodynamic calculations applied to refrigeration. Its uniqueness is that it is fully controllable via the Internet directly from a web browser like Internet Explorer or Firefox.

It consists of two cold rooms, each with their own evaporator but sharing the same cooling fluid R134a system (compressor, condenser ...).

The control and configuration of this system can be done in two ways:

a classic console coupled to a regulator PLC type industrial PAC (programmable automation controller) Compact Fieldpoint

The Compact Fieldpoint adds the possibility of remote control via the Internet, viewing the evolution curves of temperature, air and refrigerant fluid, pressure and power at various points. This allows calculating the required cooling system features such as enthalpy, entropy, Mollier diagram and performance coefficients.

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.

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
