IBM has announced the winner of an international competition that sought disaster response technologies from across industry and academia. Prometeo, winner of the Call for Code 2019 Global Challenge, is an artificial intelligence system that works to protect firefighters during operations, IBM said Saturday. The arm-strapped, smartphone-sized device measures external factors that affect firefighters, such as smoke concentration, humidity and temperature. The system then links with IBM's Cloud Internet of Things platform and a machine learning model to help command centers monitor firefighter health in real time. Software developers, a nurse and a firefighter compose the Barcelona-based team that produced Prometeo.
