Abstract: Systems, methods, and apparatuses are disclosed for simplifying a point cloud. A point cloud is received where the point cloud has a plurality of points, a global spatial structure, and a local point density. The processor calculates a set of pairwise distances for the plurality of points to at least one other point in the plurality of points. A first distance matrix is generated using the set of pairwise distances. The processor calculates a second pairwise distance set where the plurality of points have a weight and generates a second distance matrix based off the second pairwise distance set. A portion of the points in the second pairwise distance set are removed based on the weight. The processor performs a comparison of the two matrices using the comparison and the global spatial structure and the local point density, and generates a second point cloud based on the second distance matrix.

Abstract: In various embodiments, a multi-layer X-ray source target is provided having two or more layers of target material at different depths and different thicknesses. In one such embodiment the X-ray generating layers increase in thickness in relationship to their depth relative to the electron beam facing surface of the source target, such that X-ray generating layer further from this surface are thick than X-ray generating layers closer to the electron beam facing surface.

Abstract: An enhanced television service provides a shared folder over a television network, such as a fiber optic network. Users, the service provider, or trusted sources, share use of a program folder via television. A user recommends content, such as a program listing, to other geographically dispersed subscribers, by sending the content to the subscribers' shared folder. Users may create a personal content guide for use instead of a standard program guide that contains identical listings for all subscribers. The shared folder may consist of programs from a variety of channels as well as other content and may be populated by trusted sources in remote locations. Users may search for content that matches search criteria and may delete or edit listings from the shared folder. The contents of the folder may not only include program listings, but also other content such as movies, television shows, web sites, photos, home videos, etc.
