Abstract
A wearable safety apparatus includes a housing, a plurality of directional thermal imaging sensors mounted on the housing and facing outwardly away from the housing in a corresponding plurality of different directions towards thermal zones of a heat source. Each sensor detects infrared radiation (IR) intensity and generates an output indicative of a temperature of the detected IR intensity in a respective thermal zone faced by a respective sensor. An interface is mounted on the housing and has a display positioned to be viewable by a user, e.g., a firefighter. A controller processes the outputs generated by the sensors, and displays at a plurality of spaced-apart positions on the display a plurality of positional thermal indicators when the temperature in the respective thermal zone is elevated. The position of each positional thermal indicator corresponds to the thermal zone faced by the respective sensor.
