Abstract: The invention describes a method and a walk through apparatus to treat surfaces with hydroxyl ions to reduce the viability and/or kill pathogens.

Abstract: A visual and tactile emergency exit system comprising a series of signs having both visual and tactile components to guide a person to the nearest exit of a room. The visual components of each sign comprises the sign's shape and text incorporated in the face of the sign. The sign is constructed of a self-illuminating material. The tactile components of each sign comprises braille translations of the sign's message mounted on the face of the sign, a minimum sign thickness, and cut out or raised text on the face of the sign. The signs are positioned in strategic locations along a wall to indicate the direction to the nearest exit, whether a person must turn or continue traveling straight at a comer, and the location of the exit door. The signs are positioned on the lower portion of the wall so that they can be easily read or touched by a prone person.

Abstract: A prefabricated, modular shelter system that utilizes a series of identical enclosures, each made from barrier panels connected to define the shape of a modifiable dodecagon prism. The top cover of each enclosure can be flat or peaked at the center. The lightweight components are easily transported, assembled, disassembled, and/or re-assembled. The design allows two or many enclosures to cluster together without interstitial triangle prism volumes forming among them. Interior space within a cluster of enclosures can be increased, decreased, or re-arranged by simple addition, removal, or relocation of enclosures. Though the enclosures are each identical in shape, they can create a limitless variety of spatial areas and configurations, thus adapting to varied uses and requirements.
