Collapsible muffler system

USPTO Application #: 20070187174
Title: Collapsible muffler system
Abstract: The muffler system of the preferred embodiment includes an outer membrane adapted to operate in a collapsed mode, wherein the outer membrane defines a first volume that facilitates portability and stowage, and in an expanded mode, wherein the outer membrane defines a second volume, which is larger than the first volume, that provides attenuation and muffling of the noise signature of the power system. The muffler system further includes an inlet coupled to the outer membrane and adapted to allow the exhaust gases and sound waves from the portable power system to enter the muffler system.
