Abstract: A packaging material comprised of a gas-impermeable base layer, an indicator layer, and a gas-impermeable top layer is disclosed. The top layer is selected to rupture upon experiencing an impingement or impact that exceeds a predetermined threshold. The indicator layer is configured to change visual appearance upon exposure to ambient air. The top layer further may be configured into a plurality of cells, with each cell filled with a gas that is inert with respect to the indicator layer. The cells may be of a size and shape configured to indicate the location and shape of an impingement or impact, to alert a recipient of an item protected by the packaging material of an area that may require further inspection.

Abstract: An airflow treatment system is worn or carried by a user and irradiates an air flow with energy in the electromagnetic spectrum, such as UV light, before the air is inhaled by the user. The irradiated energy is of sufficient power and duration to substantially cleanse the air of airborne viruses and the like prior to inhalation. The system includes a light source with a power supply to generate the energy for irradiation. A face mask is worn by the individual so that outside air is drawn into the system, and the airflow passes through a airflow treatment chamber before it is inhaled by the user. The airflow is irradiated by the energy, such as UV light, while passing through the airflow treatment chamber such that airborne virus microorganisms in the airflow are substantially destroyed or rendered unharmful before the airflow is inhaled by the user.
