A method for dynamically determining a separation distance in which thermal images of a space are received that indicate a count and location of users within the space, temperature of the users within the space are received along with acoustic data from the users within the space, which is filtered to include specific symptom-related sounds and discard other sounds. The one or more processors generate a probability of a contagious infection of users within the space at a location determined by the thermal images, based on correlating the temperature and the acoustic data associated with the users within the space. A separation distance from the users within the space is calculated, based on the locations and the probabilities of infection of the users within the space, and a notification corresponding to the calculated separation distance is delivered to a protected user.

A computer determines one or more temperature sensitive components from a part details in a bill of materials for soldering on a printed circuit board assembly, where the bill of materials is a record comprising part details having a reference designator. The computer determines whether temperature sensitive components exist in the bill of materials. Based on determining that at least one of the temperature sensitive components exist in the bill of materials, the computer determines temperature limits for each temperature sensitive component based on the reference designator, monitors, using the thermographic cameras the measured temperatures of the temperature sensitive components during soldering in the reflow oven. Then, based on determining that the measured temperatures of the temperature sensitive components exceeds the temperature limits, the computer determines an elapsed time outside of the temperature limit when the measured temperatures of the temperature sensitive components exceeds the temperature limits.
