Abstract
A display assembly which detects gas recirculation or airway occlusion includes an electronic display located within a housing, and an open loop pathway through said housing. Fans along the open loop pathway ingest, circulate, and exhaust ambient air while sensors take measurements. A processor takes data from the sensors and compares it to weather data gathered for the location of the display assembly, as determined by a location detection device. An alert is generated if the measured characteristics of the ambient air are not within a margin of error of the gathered weather conditions. Operations of the display assembly may also be adjusted.
