Filed:

Dec 21, 2010

Appl. No.:

12/974706

Inventors:

Willem VAN DAM - Novato CA, US
Jim MCGEEHAN - San Rafael CA, US
Trevor MILLER - Dublin CA, US
James BOOTH - Napa CA, US

Assignee:

Chevron U.S.A. Inc. - San Ramon CA

International Classification:

C10M 169/04

US Classification:

508110

Abstract:

Provided is a lubricating oil composition for internal combustion engines comprising at least one hydrocarbon base stock which is determined to exhibit a 40 C. PVC/100 C. PVC ratio approaching one or greater, and one or more lubricating additives. Also provided is a method for preparing such a composition, which includes determining the 40 C. PVC/100 C. PVC ratio of a hydrocarbon base stock oil, and selecting a hydrocarbon base stock oil which exhibits a 40 C. PVC/100 C. PVC ratio approaching one. One or more lubricating additives is then added to the selected base stock oil.

Abstract:

In one embodiment, a method includes receiving image data corresponding to an external environment of a user. The image data is captured at a first time and comprises a body part of the user. The method also includes receiving a first tracking data generated based on measurements made at the first time by at least one motion sensor associated with the body part; generating, based at least on the image data, a model representation associated with the body part; receiving a second tracking data generated based on measurements made at a second time by the at least one motion sensor associated with the body part; determining a deformation of the model representation associated with the body part based on the first tracking data and the second tracking data; and displaying the deformation of the model representation associated with the body part of the user.
