Abstract: A computer system displays a representation of a field of view of the one or more cameras, including a representation of a portion of a three-dimensional physical environment that is in the field of view of the one or more cameras. The computer system receives a request to add a first virtual effect to the displayed representation of the field of view of the one or more cameras. In response to receiving the request to add the first virtual effect to the displayed representation of the field of view of the one or more cameras and in accordance with a determination that the first virtual effect requires a scan of the physical environment, the computer system initiates a scan of the physical environment to detect one or more features of the physical environment and displays a user interface that indicates a progress of the scan of the physical environment.

Abstract: An elastomer composition includes guayule rubber and a butadiene rubber, with at least about 5 phr guayule rubber based on 100 phr elastomer. The cured rubber has a higher coefficient of friction as compared to a cured rubber of the same formulation except using Hevea rubber rather than guayule rubber.

Abstract: Curable rubber compositions and cured articles are based on the use of zinc activator compositions for the sulfur cure. Activator compositions contain zinc and a polymeric component having a plurality of COOH groups, at least some of which are neutralized with the zinc. With polymeric zinc activators, sulfur cure can be activated at levels of zinc below those used in conventional systems.

Abstract: Rubber in its uncured state is very tacky and rubber forms such as pellets, sheets, etc., tend to be hard to process due to the agglomeration and sticking of these rubber forms. Aspects of the invention use cured rubber powder as an anti-tack agent in a molding rubber mixture. In one aspect, the cured rubber powder has a particle size between 50 and 250 ?m in the uncured rubber forms, a diameter of between 1 and 10 mm, and a length of between 1 and 15 mm.

Abstract: Cured rubber compositions with reduced divalent metal levels and improved physical properties are prepared using methods that limit or avoid a deleterious side reaction, and that make activator compounds available only during cure and not earlier during mixing. Specifically, the presence of activator soap (or of components that can form the activator soap in situ) and silica filler together is avoided or minimized in process steps where the temperature would tend to be above 100° C. or 110° C. The use of ZnO for example can be reduced by as much as 90˜95% in a typical rubber compound.
