Sound Analysis-Synthesis
iNSTiTUT DE RECHERCHE ET COORDiNATiON ACOUSTiQUE/MUSiQUE
The analysis of sounds includes methods enabling the permanent extraction or automatic structuring of diverse sorts of information given off by the signal, such as the fundamental frequency or the spectral evolution determining the pitch and timbre of a perceived sound. Information outside what is strictly musical is also taken into consideration, notably concerning industrial acoustics, sound design and multimedia as well as the automatic indexing of recorded sounds. The methods used are based on signal processing, statistical analysis, information theory, machine learning and recognition techniques, but also on knowledge of auditory perception.

Whole Body Vibration Analysis
Whole Body Vibration (WBV) testing is a type of vibration analysis geared towards estimating the effects on the operator. There are three categories of concern for the operator, health and comfort, perception, and motion sickness. The goal for any WBV test is to ensure that under normal operating conditions there is no significant or lasting effect of the vibration experienced by the operator.

Gloss & Reflectance
Visual appearance can determine a person’s perception of a product. Colour and Gloss are two key parameters that are used to define a product’s overall quality. Perception is subjective, but Elcometer’s range of gloss meters, DOI meters and colour assessment equipment can quantify appearance measurement. The ability of a surface to reflect light without scattering is known as gloss. Using a gloss meter, gloss is measured by directing a constant intensity light beam at a fixed angle to the test surface and then by monitoring the amount of reflected light at the same angle. Different surfaces require different reflective angles.

Brake Test Systems
Giant 8000 Series
Customer perception of vehicle quality is closely related to the NVH behaviour of the vehicle. With the HORIBA ATS Brake testing system, NVH relevant design features are analyzed and various metrics stored in the database of the automation system. For friction borne vehicle NVH problems coming from the brake and its components the GIANT 8000 Series is the ideal tool to resolve it. The GIANT 8000 Series is superior NVH test system providing you with the best testing conditions for all types of vehicles. Test brake fixtures could be tested with a complete wheel suspension system. In a semi acoustic chamber NVH tests could be realized and drum brakes and disc brakes including the vehicle axle could be tested.

Simulator for Test Driving of Drones & Robots
Aerial Informatics & Robotics Platform
The Aerial Informatics and Robotics platform solves for these two problems: the large data needs for training, and the ability to debug in a simulator. It will provide realistic simulation tools for designers and developers to seamlessly generate the copious amounts of training data they need. In addition, the platform leverages recent advances in physics and perception computation to create accurate, real-world simulations. Together, this realism, based on efficiently generated ground truth data, enables the study and execution of complex missions that might be time-consuming and/or risky in the real-world. For example, collisions in a simulator cost virtually nothing, yet provide actionable information for improving the design.
