Abstract: A system, device, and method for sensing air quality with a sensor platform is disclosed. The method includes (i) directing a set of mobile sensors to a coarse region wherein the coarse region has coarse size based on variance of prior air quality measurements taken at locations within a vicinity of the coarse region, and (ii) directing the set of mobile sensors to a fine region wherein the fine region has a fine size based on variance of prior air quality measurements taken at locations within a vicinity of the fine region. The variance of air quality measurements associated with the fine region is greater than a variance of air quality measurements associated with the coarse region.

Abstract: A system, device, and method for sensing air quality with a sensor platform is disclosed. The method includes (i) directing an air quality measurement system to a predicted high information region wherein the predicted high information region is determined based on high variance of prior air quality measurements taken at different times, (ii) directing the air quality measurement system to a predicted low information region wherein the predicted low information region is determined based on low variance of prior air quality measurements taken at different times. The air quality measurement system is preferentially directed to the predicted high information region.

Abstract: The present invention is directed to a collimator that comprises grooves or channels in the submicrometer to micrometer range. The present invention is also related to uses of a collimator and collimator holder as described herein as well as apparatuses comprising the same.
