Abstract: A face mask having mechanical, chemical, and electrostatic barriers to the movement of a material into and out of a face mask are described herein. Various examples of the face mask described herein use electrostatic charges to capture and, in some examples, inactivate viruses, germs, fungi, or bacteria (or other material). The use of a biocidal agent combined with electrostatic charges provides an additional measure for capturing and inactivating at least a portion of pathogen(ic) microorganisms.

Abstract: Automatically tagging a trial balance is disclosed. The trial balance is received in a user specific format. Items in the trial balance are analyzed to identify a first item that likely corresponds to a first data grouping of a first data subset of the trial balance. Items in the trial balance are analyzed to identify a second item that likely corresponds to a second data grouping of a second data subset of the trial balance. Information is provided to display at least a portion of the first data subset of the trial balance identified as the first data grouping and to display at least a portion of the second data subset of the trial balance identified as the second data grouping to facilitate user verification of the identification of the first data subset as the first data grouping and the identification of the second data subset as the second data grouping.
