Obviousness

I cannot perform an obviousness analysis of US patent 10117290 under 35 U.S.C. § 103 as requested. The provided patent text does not contain a "Prior Art" section listing specific prior art references that would be used for such an analysis. While the patent includes "Prior art keywords" and a "Priority date," it does not enumerate documents or inventions as prior art against which the claims could be evaluated for obviousness.
