Abstract
A portable communication device includes one or more miniature sensors to sense one or more environmental gases. A processor is coupled to the miniature sensors and is configured to enhance location detection by determining a sensor signal transition. The sensor signal transition is caused by subsequent exposures of at least one of the miniature sensors to environmental gases of a first air composition and a second air composition. The first air composition and the second air composition are respectively associated with a first location and a second location.
