CA 2492959

Portable and wearable chemical detector devices, such as badges, that are analyte-general, rather than analyte-specific, and which provide an optimal way to notify and protect personnel against known and unknown airborne chemical hazards. The devices of the present invention are advantageously low- cost, have low-power requirements, may be wearable and are designed to detect and alarm to a general chemical threat. A sensor device of the present invention in one embodiment includes two or more sensor devices, a processing module coupled to each of the sensor devices and configured to process signals received from each of the two or more sensor devices to determine an environmental state; and a communication module that communicates information about the environmental state to a user.

L'invention concerne des dispositifs de détection chimique portables et prêts-à-porter, tels que des badges, non spécifiques à une substance à analyser, plutôt que spécifiques à une substance à analyser, et fournissant un moyen optimal pour informer et protéger du personnel contre des risques chimiques connus ou inconnus en suspension dans l'air. Ces dispositifs sont bon marché, consomment peu d'énergie, peuvent être portés et sont conçus pour détecter et signaler une menace chimique générale. Un mode de réalisation de ce dispositif de détection comprend au moins deux capteurs, un module de traitement relié à chacun des capteurs, conçu pour traiter les signaux transmis par les capteurs pour déterminer un état environnemental, ainsi qu'un module de transmission servant à transmettre à un utilisateur des informations relatives à l'état environnemental.
