  • Patent number: 7880743
    Abstract: An improved attribute determination process allows the sharpness of a surface attribute function to be adjusted on a per-object, per-surface, per-texture, per-function, or other appropriate basis. A computer-based animator then can selectively adjust the sharpness or other attribute(s) of portions of a to-be-rendered image without significantly increasing the rendering time. For a selected texture, corresponding sampling regions will be shifted about the respective surface points projected in texture space. A multi-dimensional set of sub-regions can be generated for the shifted sampling region. Bounding boxes can be determined for each sub-region, the boxes occupying less area, such as in texture space, than a single bounding box for the original sampling region. The bounding boxes can be used for local attribute determinations (such as texture lookups) for each sub-region, with the local attributes being processed to determine an attribute for the respective surface point.

  • Patent number: 7880770
    Abstract: Tools for controlling cameras (and other objects), using an input device. Some such tools may establish a threshold, above which the input from the input device is fed directly to the object being controlled, and below which the input signal is processed to provide smoother operation. This can allow for direct control over a camera (or other object) in large movements but still allow for smooth, controlled movements when slower movement is desired.

  • Patent number: 7879729
    Abstract: In a method of forming micro patterns of a semiconductor device, first etch mask patterns are formed over a semiconductor substrate. An auxiliary film is formed over the semiconductor substrate including a surface of the first etch mask patterns. Second etch mask patterns are formed between the auxiliary films formed on sidewalls of the first etch mask patterns. The first etch mask patterns and the second etch mask patterns are formed using the same material. The auxiliary films between the first and second etch mask patterns are removed. Accordingly, more micro patterns can be formed than allowed by the resolution limit of an exposure apparatus while preventing misalignment.

  • Patent number: 7879066
    Abstract: A luminal occlusion device comprises a tension member, an elongate shaft, and a flat film having an axial receptacle which is received over a distal portion of the tension member. The flat film has proximal and distal ends which are attached to the distal ends of the tension member and the elongate shaft, respectively. Thus, distal advancement of the tension member relative to the shaft will cause the flat film to assume a low profile configuration, while proximal retraction of the tension member relative to the elongate shaft will cause the flat film to assume a foreshortened, compacted configuration. The film usually includes one or more radioopaque markers which help shape the compacted film.

  • Patent number: 7880026
    Abstract: A rapid, simple and versatile metal organic framework molecule (MOF) synthesis method particularly adapted to make non-linear MOFs includes heating MOF precursors, such as a metal or metal oxide and an organic ligand, in a microwave oven for a period sufficient to achieve crystallization. Microwave-assisted MOF synthesis yields high quality MOF crystals in a reaction time ranging from about 5 seconds to about 2.5 minutes, compared to hours and days required in conventional solvothermal and hydrothermal methods. In addition, microwave assisted methods provide MOF materials with uniform crystal size and well-defined shape. Further, microwave synthesis of MOFs allows the size and shape of MOF crystals to be tailored for use in a wide range applications by manipulating reaction conditions. Secondary growth processes may also be employed to grow larger crystals using seeds obtained from microwave-assisted synthesis methods.

  • Patent number: 7882296
    Abstract: Circuits, apparatus, and methods for avoiding deadlock conditions in a bus fabric. One exemplary embodiment provides an address decoder for determining whether a received posted request is a peer-to-peer request. If it is, the posted request is sent as a non-posted request. A limit on the number of pending non-posted requests is maintained and not exceed, such that deadlock is avoided. Another exemplary embodiment provides an arbiter that tracks a number of pending posted requests. When the number pending posted requests reaches a predetermined or programmable level, a Block Peer-to-Peer signal is sent to the arbiter's clients, again avoiding deadlock.
