A method andor system for a breathable air safety system for both emergency and civilian personnel are disclosed. The panel includes a retainer portion and a door portion circumscribed by the retainer portion. The coprocessor is suitable to be tightly coupled with raw image sources like sensors. The outsoles can prevent or reduce the accumulation of soil on the footwear during wear on unpaved surfaces such as sporting fields. The system further includes trial period checking logic configured to retrieve a new dynamic list and check whether a trial period for a media file has expired by determining whether the media file is listed on the new dynamic list and offer presentation logic configured to offer a user a license for continued use of a media file that has an expired trial period.
