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: Embodiments are directed to spinal treatments and, more particularly, to a compression device for use in spinal surgery that includes integrated compression and distraction. In an exemplary embodiment, the present invention provides a compression device for use in a spinal surgery. The compression device may comprise a first sleeve having a proximal end and a distal end, wherein the distal end of the first sleeve is arranged for placement over at least a portion of one or more pedicle screw tulip. The compression device may further comprise a second sleeve having a proximal end and a distal end, wherein the distal end of the second sleeve is arranged for placement over at least a portion of one or more additional pedicle screw tulip. The compression device may further comprise a linear drive, wherein the linear drive is operable to cause movement of the first sleeve and/or the second sleeve for compression and/or distraction.
