Sonar
FRUn sonar utilise des signaux acoustiques pour détecter, localiser ou suivre des objets sous l’eau. Il peut être actif, en émettant un signal puis en analysant son retour, ou passif, en écoutant. Les solutions de coque, remorquées et déployables répondent à des contraintes différentes. Une portée ou précision ne doit pas être déduite du seul nom de la technologie.
ENSonar uses acoustic signals to detect, locate or track underwater objects. Active systems transmit signals and analyze their returns; passive systems listen. Hull-mounted, towed and deployable systems address different constraints. Range or precision cannot be inferred from the technology name alone.

- BIBusiness intelligence turns data into information for decision-making. It combines data preparation, analysis and visualization but does not itself guarantee data quality.
- CRMCRM comprises practices and tools for managing customer and prospect relationships. CRM software centralizes contacts, sales opportunities and interaction history.
- ÉlastomèreAn elastomer is a polymer material capable of deforming and recovering much of its shape after load removal within its operating limits. It may be used for flexible parts, coverings, seals or contact components. Hardness alone is insufficient for selection: temperature, chemicals, abrasion, compression and ageing should also be considered. Compatibility must be confirmed for the exact formulation and application.
- Emballage de protectionProtective packaging is designed to limit product damage during handling, storage or transport. It may combine a crate, blocking and cushioning adapted to the product. Design considers mass, fragility, handling access and the logistics route. Humidity, vibration, shock or export requirements must be defined and validated using appropriate methods; no package protects against every risk.
- EmbeddingVector representation of a text (often 1,024 to 3,072 dimensions) capturing its meaning. AI engines convert indexed content and the user's question into embeddings to measure semantic similarity.
- ERPAn ERP integrates business functions through shared data and processes. In a plant it can coordinate orders, purchasing, inventory, planning and accounting depending on the deployed modules.
