Abstract: An electronic device emulating nonvolatile memory includes: a first memory including a data block in which data is stored and a metadata block in which metadata relating to the data is stored; a second memory in which data to be used by the electronic device is stored; and a processor configured to manage data of the first memory and the second memory. The processor may generate a random value for distinguishing between first data and other data when the first data is stored in the first memory, include the random value in the first data and then store the first data in the data block, and store, in the second memory, a password value obtained by encrypting information on the first data based on the random value and a roll-back key.

Abstract: An apparatus for obtaining a three-dimensional (3D) face model using a portable camera, comprising: a face image capturing unit; a face image processing unit; a 3D face mesh creating unit configured to analyze relationships of the face images to create a 3D user face mesh; a standard face model matching unit configured to match a 3D face standard model to the 3D face mesh created by the mesh creating unit to create a final high-quality user face model; a face skin texture synthesizing unit configured to create a face skin texture from the captured images; and a realistic face rendering unit configured to perform realistic rendering by using the user's high-quality 3D face model and the skin texture.

Abstract: A virtual plastic surgery SNS service apparatus for providing a virtual plastic surgery service, comprising: a three-dimensional (3D) face model generation unit configured to generate a 3D face model by using an image from a portable camera; a 3D face model database management unit configured to store and manage the 3D face model and a result of virtual plastic surgery such that the 3D face model and the result of virtual plastic surgery are shared by people on a SNS (Social Network Service); a virtual plastic surgery simulation unit configured to allow a user to directly perform a simulation of virtual plastic surgery by using a certain facial part of a shared face model of a friend or by using a certain facial part of a known entertainer; and a social network service unit configured to allow the user to share the simulation result with people on the SNS or to connect the user to an expert to be consulted.

Abstract: An internal combustion engine that combines the concepts of a rotary engine with those of a piston engine. This engine can be adapted to embody many different forms to be appropriate for operating environments ranging from small engines up to large engines for use in power plants. The engine is less complex than a conventional reciprocating engine, but more efficient than a conventional rotary engine.
