Abstract: A compressed gas energy harvesting system (CGEHS) for use in a gas delivery system is disclosed herein. The CGEHS comprises a gas control device connected to a compressed gas container and in fluid communication with a fluid within the compressed gas container. The gas control device comprising one or more electrical components. The CGEHS further includes a power storage device for providing power to the one or more electrical components and a potential energy converter coupled to the one or more electrical components, the potential energy converter for supplying power to at least one of the one or more electrical components and the power storage device by converting the potential energy retained by the compressed gas container into electrical energy.

Abstract: An information gauge apparatus and method for providing both visual and audio readings of pressure within a pressure vessel. The information gauge apparatus includes a digital display coupled to a printed circuit board in communication with a pressure sensor. The digital display illustrates indicia relating gas pressure levels provided by the pressure sensor to the printed circuit board during use. The gauge further comprises an audible indicator coupled to the printed circuit board, the audible indicator provides an audible signal relating to gas pressure levels sensed by the pressure sensor to the printed circuit board during use. The gauge also includes a mechanical sensor providing a mechanically sensed reading value to a visual indicia display on the information gauge apparatus relating to gas pressure levels during use.
