Abstract: A particulate monitor includes a housing, an air-moving device coupled to the housing, and an air passageway disposed at least partially within the housing. The air-moving device is operable to create an airflow through the air passageway. The particulate monitor may include a real-time measuring device positioned at least partially within the housing and in fluid communication with the air passageway and a particulate collection device positioned at least partially within the housing and in fluid communication with the air passageway. A collection device may be positioned downstream of the real-time measuring device. At least one impactor may be movably coupled to the housing to be movable between a first position adjacent the air passageway and a second position displaced from the air passageway.

Abstract: A personal temperature monitor senses inner ear temperature and uses the sensed ear temperature to determine the internal core body temperature. The monitor places an audible signal device at the ear of the individual being monitored to alert the person when elevating core body temperatures may be indicative of a potentially dangerous heat stress condition.
