The United States Patent and Trademark Office (USPTO) has granted Amazon a new patent that could transform an unmanned aerial vehicle (UAV) into a mini airship. The USTPO published the schematics on March 9, first reported by SlashGear, which shows the UAV will have an inflated membrane and compressed gas chamber containing hydrogen - mounted into its airframe that could be deployed when entering a location where noise reduction is desirable.
