Personal protective equipment (PPE) with analytical stream processing for safety event detection

A computing device comprising:

• one or more computer processors that receive usage data from at least one sensor of a respirator including a self-contained breathing apparatus, the at least one sensor being configured to generate the stream of usage data, the at least one sensor being of a type selected from the following group of sensors:
• extension sensor, tension sensor, accelerometer, location sensor, position sensor, and altimeter;
• a memory configured to store at least a portion of the usage data and at least one model for detecting a safety event signature indicative of an occurrence of a safety event, wherein the at least one model is based at least in part on a set of usage data generated,
• prior to receiving the usage data from the at least one sensor, by one or more other respirators of a same type as the respirator;
• and
• one or more computer processors configured to:
• detect the safety event signature indicative of the occurrence of the safety event in the usage data based on processing the usage data with the model, and
• perform at least one operation in response to detecting the safety event signature.

A non-transitory computer-readable storage medium encoded with instructions that, when executed, cause at least one processor of a computing device to:

• receive usage data from at least one sensor of a respirator that at least includes a self-contained breathing apparatus, the at least one sensor being configured to generate the stream of usage data, the at least one sensor being of a type selected from the following group of sensors:
• extension sensor, tension sensor, accelerometer, location sensor, position sensor, and altimeter;
• store at least a portion of the usage data and at least one model for detecting a safety event signature indicative of an occurrence of a safety event, wherein the at least one model is based at least in part on a set of usage data generated, prior to receiving the usage data from the at least one sensor, by one or more other respirators of a same type as the respirator;
• and
• detect the safety event signature indicative of the occurrence of the safety event in the usage data based on processing the usage data with the model, and
• perform at least one operation in response to detecting the safety event signature.
