Abstract: A system, wearable device and management device provided for predicting a flashover event. According to one aspect of the disclosure, a wearable device for predicting a flashover event is provided. The wearable device includes at least one thermal sensor configured to generate thermal data associated with an environment, and processing circuitry configured to: determine a risk of ignition of at least one combustible gas in the environment based on the thermal data, and trigger at least one action based on the determined risk of ignition.

Abstract: In general, techniques are described for a personal protective equipment (PPE) management system (PPEMS) that uses images of optical patterns embodied on articles of personal protective equipment (PPEs) to identify safety conditions that correspond to usage of the PPEs. In one example, an article of personal protective equipment (PPE) includes a first optical pattern embodied on a surface of the article of PPE; a second optical pattern embodied on the surface of the article of PPE, wherein a spatial relation between the first optical pattern and the second optical pattern is indicative of an operational status of the article of PPE.

Abstract: A system and method for determining a sensing capability of a PAAV and for performing at least one operation of the PAAV as a function of at least one policy applied to the sensing capability determined for the PAAV. A sensing capability of the PAAV is determined at least in part on sensor data received from at least one sensor accuracy measurement feature deployed along a pathway. At least one operation of the PAAV is performed as a function of at least one policy applied to the sensing capability determined for the PAAV.
