Abstract: Methods and systems for generating customized learning programs include performing the operations of: receiving learning materials for a target platform; selecting a first set of learning materials based at least in part upon a first role; generating a first customized learning program which includes one or more first learning steps using the first set of learning materials; selecting a second set of learning materials based at least in part upon a second role, the second role being different from the first role, the second set of learning materials being different from the first set of learning materials; generating a second customized learning program which includes one or more second learning steps using the second set of learning materials; and deploying customized learning programs which include the first customized learning program and the second customized learning program.

Abstract: An entrainment-based filtering system for use in connection with a facemask or respirator that includes: a filter housing defining an interior volume comprising at least one airflow pathway having an airflow pathway length that is longer than the length of the interior volume and spaced within the interior volume; and a plurality of entrainment substrates. The plurality of entrainment substrates is positioned within the at least one airflow pathway and the plurality of substrates and the dimensions of the at least one airflow pathway together function to entrain particles on the surface of the chemically coated entrainment substrates and prevent at least 95% of particles traveling through the at least one airflow pathway from exiting the entrainment-based filter.
