Heat treatment is used to alter the physical properties of a material – typically to increase the strength and wear characteristics of a chain while maintaining adequate toughness and ductility for the application. Heat treatment involves the use of heating, rapid cooling (quenching), and sometimes even chilling components to extreme temperatures to achieve a desired result. 

In Industrial Internet of Things (IIoT) connected devices, sensors are responsible for collecting data from various functions of the machine. As most connected devices have multiple sensors, it is crucial that the data being collected is conveyed to users in the most “context-driven" way possible. This is where data aggregation or “sensor fusion” comes into play.
