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 olefin metathesis process involving contacting an unsaturated fatty acid ester or unsaturated fatty acid, such as methyloleate or oleic acid, with a lower olefin, preferably ethylene, in the presence of a metathesis catalyst so as to prepare a first product olefin, preferably, a reduced chain ?-olefin, such as methyl-9-decenoate or 9-decenoic acid, respectively. The metathesis catalyst contains ruthenium or osmium and a chelating ligand, preferably, a chelating ligand containing a carbene moiety and a second donor moiety of a Group 15 or 16 element Optionally, the catalyst can be supported on a catalyst support, such as, a cross-linked polymeric resin.

Abstract: An apparatus in accordance with this invention includes an alignment mark that is formed in a substrate. The alignment mark extends across a dice line so that, upon dicing the substrate, the mark is exposed in the substrate's side edge. The mark is formed at a predetermined distance from a position at which a feature is desired to be formed on the substrate's side edge using a mask. Accordingly, the mark is a positional reference that can be used for highly accurate placement of the feature on the side surface of the substrate with the mask. Preferably, the mark is formed of metal or other material enhanced to a size that is readily detectable by an alignment system with which the mark is to be used. The invention also includes methods for making the alignment mark.

Abstract: The present invention is directed to a process for producing a hydrogenated polymer or copolymer by hydrogenating prior to polymer isolation or finishing.

Abstract: A longitudinal gage fixture extends the entire length of the cutting blade and provides positively locked, parallel surfaces that uniformly and reliably set the proper height of the gage blade along its length while in a blade holder, In use, the device requires no frictional movement of the gage along the length of the blade, and adjustment of the blade may be achieved in an accurate, single-step process. The entire blade and holder assembly is positioned within the gage fixture and adjusting screwy at the base of the holder are accessed through apertures in a base plate of the gage fixture so that all necessary adjustments of the blade may be made with the holder insitu without any movement of the holder. Only movement of the blade within the holder is required during adjustment. Once properly adjusted, the tightening down of the blade may also be accomplished with the blade and holder still within the gage fixture.

Abstract: An air-probe structure of an air-gauge nozzle that defines an air-probe bore having an elongated, relatively small-area output tip (e.g., 0.3.times.1.3 millimeters) situated at the air-probe structure's output end. Such an air-gauge nozzle is useful in controlling the distance between the bore's output tip and a rowbar workpiece (employed in an optical microlithographic pole trimming step of the fabrication process for thin-film heads) in accordance with the air pressure measured by the air gauge. The air-probe structure's output end preferably also comprises a relatively large-area protective manifold (e.g., 6.times.7 millimeters) surrounding the elongated, relatively small-area output tip.

Abstract: Octahydrofluorenyl metal complexes, such as octahydrofluorenyltitanium trichloride, or ring substituted octahydrofluorenyl metal complexes wherein the metal is in the +2, +3 or +4 formal oxidation state are prepared by reduction of tetra- or hexa-hydrofluorenyl metal complexes.

Abstract: A process of phase edge lithography is employed in the manufacture of very large scale integrated (VLSI) chips in which chrome images are biased on a phase edge of a phase shift mask (PSM) and the mask overexposed to compensate for the positive bias. This overexposure eliminates any residual images from the phase edge mask with minimum impact to the desired images. This simple process results in a trim-less phase edge process that takes advantage of the improved resolution and process latitude of phase edge PSMs while avoiding layout impacts caused by a trim mask or other phase edge elimination methods.
