Abstract
A method and apparatuses protecting a portable device from an impact are provided. An accelerometer is operable to detect acceleration of the portable device. A protective structure disposed outside of the portable device includes a substrate and an elastomeric layer arranged on the substrate. The elastomeric layer defines an inflatable region in which the elastomeric layer is not attached to the substrate. The substrate includes a fluid channel in fluid communication with a pressurized fluid source. A controller is operable to trigger the pressurized fluid source upon detection of an acceleration event, wherein the pressurized fluid source transmits pressurized fluid to the inflatable region, causing the inflatable regions to inflate. The inflatable regions provide a cushion against impacts with surfaces when the portable device is dropped or otherwise propelled toward a surface.
