Abstract: Provided is a non-Newtonian engine oil lubricant composition with improved fuel efficiency and engine wear protection. The lubricant composition includes a major amount of a base oil including a Group II base stock and an optional Group V base stock, from 0.1 to 9.0 wt. % of at least one viscosity modifier and from 0.1 to 1.2 wt. % of at least one friction modifier. The non-Newtonian engine oil lubricant composition has a kinematic viscosity at 100 deg. C. of less than or equal to 10 cSt and an HTHS (ASTM D4683) of less than or equal to 2.2 cP at 150° C. Also provided are methods of using the lubricant composition in internal combustion engines and methods of making the lubricant composition.

Abstract: A system and method for documentation and analysis of dermatological aspects of a human body. The system has a predetermined arrangement of at least three image sensors selected from visible light sensors, ultraviolet (UV) light sensors, infrared (IR) sensors. Each of the image sensors has an effective normalized focal length of from about 8 to about 28 millimeters, an aperture stepped-down to at least f/4 or higher F-stop, and a shutter exposure length of no longer than about 125 milliseconds. Output from the image sensors provide a single relatively high resolution image of a skin surface of the human body obtained from a distance of at least about 0.1 meters. A data collection and processing system is integrated with the image sensors to provide storage, analysis, and output of in-situ dermatological information to a system operator.
