Abstract: A case for a tablet computer has an upper shell and a lower shell. The upper shell has an open area through which the screen of the tablet computer is exposed. The upper shell is in sealed relation against a periphery of the tablet computer. The lower shell is in sealed relation to the upper shell. A subframe is interposed in sealed relation between the upper shell and the lower shell. The subframe has an outer periphery aligned with an outer periphery of the upper shell and the lower shell. A finned member is affixed to the shells so as to transfer heat from the tablet computer outwardly of the shells. A plurality of pins are formed in the shell and are suitable for allowing electrical connection with the tablet computer.

Abstract: The present invention is an explosion-proof case for a tablet computer that has a tablet computer having a screen and an outer periphery, an upper shell having an open area such that the screen is exposed through the open area, and a lower shell being in sealed relation to the upper shell. The upper shell is sealed against the periphery of the tablet computer. The upper shell and the lower shell contain the tablet computer therein. The tablet computer and the lower shell define an interior volume. This interior volume has at least one atmosphere of a gas contained therein. The gas is an inert gas. A valve is in communication with the interior volume so as to allow the gas to be introduced into the interior volume. The gas is maintained at a pressure of at least one atmosphere above atmospheric pressure. A subframe is interposed in sealed relationship between the upper shell and the lower shell.

Abstract: A rigid, inflatable stretcher provides the capability to carry a person who may be injured or otherwise not capable of moving them self from an inaccessible or dangerous area, such as a combat zone, a steep canyon, and/or a mountain side. The stretcher may be designed to be inflatable with durable and rugged materials providing protection and comfort for the person being carried by it. The stretcher may be designed to be easily stowable, transportable and deployable so that it can serve its intended purpose of carrying a person from a remote or hostile area.

Abstract: The present invention is directed to an escape and survival capsule that provides protection to occupants from, e.g., cataclysmic natural events such as tsunamis, flooding, monsoon, typhoons, tornadoes, hurricanes, water spouts, earthquakes and mudslides. The capsule may be designed to be inflatable with durable and rugged materials providing protection against hazardous environmental factors during one or more of the preceding cataclysmic events. The capsule may be designed to be easily stowable, transportable and deployable so that it can serve its intended purpose within minutes after the occurrence of any of the preceding or other cataclysmic events.
