Abstract: A method of polygonizing an object calculates indicators that points within a set (Q) of points within three space representing the object likely lie near a surface discontinuity of the object. A global mesh is formed around a point that likely does not lie near a surface discontinuity (i.e. a reliable point). Local meshes are formed about reliable points on the frontier of this global mesh. Each local mesh is combined with the global mesh, thereby adding to the global mesh and advancing the frontier. Once a local mesh has been formed about each reliable point on the frontier and added to the global mesh, a local mesh may be formed about a point on the frontier that is more likely to lie near a surface discontinuity. The formation of local meshes can be repeated until no frontiers are left, or until all points have been added to the global mesh.

Abstract: A method of restricting access to private keys in a public key infrastructure provides for storage of an encrypted private key at a primary site. A masked session key is stored at a secondary site, where the masked session key enables recovery of the private key. By using distributed storage architecture for recovery data, simplification can be achieved without sacrificing security.

Abstract: This invention presents a method to extract atomic parts of a graphics model using its skeleton. A skeleton is a fully collapsed body of the model, and is obtained through a novel way to contract edges of the model. From the skeleton, atomic parts or features each is a part of the model that is distinctively autonomous from its connected or neighboring body is formed through space sweeping. Next, atomic parts can be connected into a hierarchy depending on the eventual interactive visualization applications. The operation of the method includes the steps of interactively computing, displaying and recording skeleton, atomic parts, and object hierarchies in response to user commands to, for example, modifying skeleton, atomic parts or object hierarchies. Object hierarchies are useful to various applications such as object scene management, view-dependent simplification, mesh-mapping, morphing, and building bounding volume hierarchies.

Abstract: A modified comb (10, 10A, 10B or 10C) for heating drone bee larvae and pupae in a hive (100) is described. The comb includes wires (11, 11A, 11B, 11C, 11D) for treat the drone larvae and pupae(P) to kill the mites (M) on the larvae and pupae. By this method, the mites are prevented from infesting the hive.
