International Classification:

C10M159/00

US Classification:

208/018000, 208/019000

Abstract:

This invention relates to base stocks and base oils that exhibit an unexpected combination of high viscosity index (130 or greater) and a ratio of measured-to-theoretical high-shear/low-temperature viscosity at -30C or lower and the methods of making them. Specifically, the present invention relates to low-volatility/low-viscosity lubricant base stocks, lubricant base stocks and base oils, formulated lubricant compositions or functional fluids comprising these base stocks and methods of making them. More particularly, this invention relates to lubricant compositions of low-temperature flow capability and low viscosity for passenger car motor lubricants of SAE 0W-XX grade (where XX=40 or lower), methods for optimizing fuel economy using the same, and methods or processes to produce them.

International Classification:

A61B 19/00
A61B 1/00

US Classification:

600111, 600166

Abstract:

In one embodiment of the invention, a method for a minimally invasive surgical system is disclosed. The method includes capturing and displaying camera images of a surgical site on at least one display device at a surgeon console; switching out of a following mode and into a masters-as-mice (MaM) mode; overlaying a graphical user interface (GUI) including an interactive graphical object onto the camera images; and rendering a pointer within the camera images for user interactive control. In the following mode, the input devices of the surgeon console may couple motion into surgical instruments. In the MaM mode, the input devices interact with the GUI and interactive graphical objects. The pointer is manipulated in three dimensions by input devices having at least three degrees of freedom. Interactive graphical objects are related to physical objects in the surgical site or a function thereof and are manipulatable by the input devices.
